Influencing the future: interactions of skeleton, energy, protein and calcium during late gestation and early lactation 
Ian J. Lean, Peter J. DeGaris, Pietro Celi, David M. McNeill, Rachael M. Rodney and David R. Fraser

The surprising findings in mice of an important role in energy metabolism of osteocalcin raised the question ‘why would a bone-specific hormone (osteocalcin) regulate energy metabolism’. We identify evidence to support a similar role for calcium and bone in energy metabolism of cattle to that found in mice. These relationships, identified in mice and cattle, and probably represent important adaptations of metabolism in mammals to the challenges of lactation.

A review on the effects of mycotoxins in dairy ruminants 
I. Rodrigues

When toxins produced by moulds are ingested by ruminants, the adverse impacts may range from sub-clinical effects to overt disease manifestations. This paper covers such effects which are not only witnessed at the farm level but which may also result in public health concerns should such metabolites be transferred into milk.

Animal welfare: towards transdisciplinarity – the European experience 
Isabelle Veissier and Mara Miele

Researches in animal welfare are carried out in various disciplines (ethology, animal health, sociology...) that rarely exchange with each other. We argue that it is time to reinforce links between disciplines and develop interdisciplinary projects (between scientific disciplines) or even transdisciplinary projects (beyond scientific disciplines and with stakeholders) to address animal welfare in a holistic way and to be able to efficiently improve the welfare of animals.

Tropical cattle methane emissions: the role of natural statins supplementation 
C. A. Ramírez-Restrepo, C. J. O'Neill, N. López-Villalobos, J. Padmanabha and C. McSweeney

This study examined the dose-dependent supplementation effects of fermented-Monascus purpureus red rice (FRR) containing the natural lovastatin monakolin K and other secondary compounds on dry matter intake, rumen fermentation, body growth, animal safety and methane emissions. Although to our knowledge this is the first trial that reports the anti-methanogenic potential of FRR in cattle, it is recognised that tolerance and abatement efficacy are required to be assessed in the long term. Our findings provide a framework to assess potential additive opportunities for improving the environmental performance of livestock and develop further research.

Comparison of enantiomers of organic acids for their effects on methane production in vitro 
L. G. Reis, A. V. Chaves, S. R. O. Williams and P. J. Moate

Organic acids and their enantiomers (L-tartaric acid, D-tartaric acid, DL-tartaric acid, L-malic acid, DL-malic acid, fumaric acid and citric acid) were investigated at four concentrations (0, 5, 10 and 15 mM) using in vitro incubations for their methane mitigation potential as feed additives. None of the organic acids and their enantiomers were identified as potential mitigation agents.

Storage stability of raw chevon chunks packaged in composite, bioactive films at refrigeration temperature 
Manish Kumar Chatli, Surabhi Kaura, Mohan Jairath, Nitin Mehta, Pavan Kumar and Jhari Sahoo

Composite, bioactive packaging films developed from potato starch and chitosan as base material impregnated with antimicrobial substances nisin (60 000 IU/g) and cinnamaldehyde (0.5% v/v) extend the storage life of meat and meat products while keeping the product free from antimicrobial substances. These films inhibit post-processing surface spoilage and provide oxidative stability, leading to improvement in colour, flavour and maintenance of the sensory attributes during storage.

Evaluation of growth hormone response to insulin-induced hypoglycaemia in dairy cattle during a 670-day lactation 
L. C. Marett, M. J. Auldist, W. J. Wales, K. L. Macmillan, K. DiGiacomo and B. J. Leury

Marked variation exists between cows in their ability to maintain extended lactations which is partly regulated by hormones that affect nutrient partitioning. Growth hormone promotes milk production and persistency and was measured following infusion of insulin in dairy cows during an extended lactation, with the greatest response occurring in early-mid lactation. The insulin tolerance test could potentially be used to identify cows with greater growth hormone secretory responses and improved milk production.

Price risk exposure of Australian Merinos – is it in the bloodline? 
Karl Behrendt

Australian Merino bloodlines are known to vary in their wool production and potential for meat production, as such, the process of identifying more profitable bloodlines needs to consider the impact of wool and meat market price changes. This study defines the price risk profiles of Merino bloodlines which are influenced by fibre diameter and clean fleece weight, and to lesser extent bodyweight. By using this process, sheep producers have the capacity to identify more profitable and risk-efficient bloodlines.

Mass to height relationships in annual pastures and prediction of sheep growth rates 
S. M. Robertson

The intake of pasture by sheep is influenced by its height. This study showed that the relationship between pasture height and mass differs between pasture types, but is highly variable within pasture types. Prediction of intake and liveweight change by sheep can be improved if appropriate pasture height for mass is used, and the relationships shown in this study may assist with the development of simulation models.

How feasible is it to replace urea with nitrates to mitigate greenhouse gas emissions from extensively managed beef cattle? 
M. J. Callaghan, N. W. Tomkins, I. Benu and A. J. Parker

Feeding nitrogen in the form of nitrate, rather than urea, reduces methane emmissions by ruminants. This paper discusses why this particular abatement strategy may be considered attractive to the extensively managed, grazing beef cattle industry. The potential for adverse consequences arising from nitrate supplementation may be elevated in this environment, necessittating further investigation prior to this strategy being considered effective and safe.

Cysteamine hydrochloride increases bodyweight and wool fibre length, improves feed conversion ratio and reduces methane yield in sheep 
M. C. Barnett and R. S. Hegarty

Developing processes which reduce enteric methane production while increasing animal productivity has become critical for sustainable livestock production. Cysteamine hydrochloride, a naturally derived metabolic compound of cysteine, is capable of achieving both goals by reducing methane emissions while increasing wool growth and weigh gain in sheep. Therefore, CSH has the potential to meet the global rise in livestock product demand with a reduced greenhouse gas footprint.

Characterising barrier function among regions of the gastrointestinal tract in Holstein steers 
G. B. Penner, J. R. Aschenbach, K. Wood, M. E. Walpole, R. Kanafany-Guzman, S. Hendrick and J. Campbell

Barrier function of the gastrointestinal tract (GIT) is an essential component of the innate immune system and for efficient nutrient transport. The objective of this study was to characterise the regional variation in the barrier function of the GIT in Holstein calves. This study indicates that the translocation of inulin across the omasum and rumen is greatest while the translocation of mannitol and Gt were greatest in the jejunum.

Growth rate of weaned lambs grazing brown midrib sorghum (Sorghum bicolor) supplemented with increasing levels of soybean meal 
L. Piaggio, M. de J. Marichal, M. L. del Pino and H. Deschenaux

In Uruguay, spring-born lambs are weaned in summer, when native pastures present low energy and protein content. Some feeding alternatives, such as supplementation and grazing on summer annual crops (soybean and brown midrib sorghum) have been tested. Brown midrib sorghum is selected for its high energy content, and good responses have been obtained when protein supplements are supplied. However, protein supplements are expensive, and it is essential to determine performance response curves of lambs to increasing levels of protein sources.

Survey of Bali bull fattening practices in central Lombok, eastern Indonesia, based on feeding of Sesbania grandiflora 
Dahlanuddin, Baiq T. Yuliana, Tanda Panjaitan, Michael J. Halliday, Elske van de Fliert and H. Max Shelton

Farmers in central Lombok Indonesia have uniquely integrated cattle fattening with intensive paddy rice production by planting the forage tree legume Sesbania grandiflora along the paddy bunds. This research provides the first detailed analysis of the production parameters of the system including: area of rice paddy and number of sesbania trees planted; harvesting and feeding practices; cattle purchases and sales; and monthly liveweight gain. This work has confirmed the high productivity of the feeding system and has highlighted the opportunity for its wider adoption, both in Indonesia and other regions in South-east Asia.

Can a single rumen sample really diagnose SARA in commercial farms? 
E. Trevisi, A. Minuti, S. Cogrossi, P. Grossi, S. Ahmed and P. Bani

Subacute rumen acidosis (SARA) is a subclinical digestive disorder, which reduces welfare and performance (milk production, milk fat content, fertility) of dairy cows. A single measurement of the ruminal pH has been proposed to diagnose SARA, but our study supports the inconsistency between the ruminal pH 6 h after feeding and several markers of performance (milk yield and composition) and health status (large metabolic profile). Thus, more sensitive and specific rumen or metabolic indices should be investigated to identify herds at risk of SARA.

Rumen degradation characteristics of ryegrass herbage and ryegrass silage are affected by interactions between stage of maturity and nitrogen fertilisation rate 
J. A. H. Heeren, S. C. Podesta, B. Hatew, G. Klop, H. van Laar, A. Bannink, D. Warner, L. H. de Jonge and J. Dijkstra

In the rumen of dairy cattle, fibre-rich feed such as grass is degraded by microbes, and products of degradation represent the major supply of nutrients to the cow. We evaluated the effect of rate of nitrogen fertilisation and grass maturity stage at harvest on rumen degradation, and found significant interaction effects. The present findings indicate that the effect of nitrogen fertilisation rate on nutrient supply to the cow is not constant but depends on grass maturity stage.

Comparison of goat, sheep, cattle and water buffalo leptin (LEP) genes and effects of the Intron 1 microsatellite polymorphism in goats 
Paola Di Gregorio, Adriana Di Trana, Pietro Celi, Salvatore Claps and Andrea Rando

This study compares the partial genomic sequence of goat, sheep, cattle and water buffalo leptin (LEP) genes and evaluate the effects of the genetic variation at this locus on some metabolic, hormonal, and dairy traits in goats. All the four species showed a microsatellite region in Intron 1. Our data bring further evidence for the role of leptin as an indicator of metabolism and mammary gland health in dairy ruminants.

Tissue mobilisation in Holstein-Friesian cattle selected for divergence in efficiency, defined as residual feed intake 
G. C. Waghorn, K. A. Macdonald and M. M. Verwoerd

Holstein-Friesian dairy cows, identified as either efficient or inefficient for feed use during growth have been evaluated during lactation to measure changes in live-weight post-partum. The groups retained their divergence for efficiency during lactation, and post-partum live-weight losses were not affected by selection. Selection for efficiency should not affect tissue mobilisation, or contribute to consequences of excessive weight loss.

Increasing ewe genetic fecundity improves whole-farm production and reduces greenhouse gas emissions intensities: 2. Economic performance 
C. K. M. Ho, T. Jackson, M. T. Harrison and R. J. Eckard

Previous modelling has shown that ewes with increased fecundity can increase production and reduce net farm greenhouse gas emissions. This study showed that a prime lamb enterprise incorporating high-fecundity ewes can also increase annual whole-farm profit compared with a baseline system typical of those in south-western Victoria. However, risk, or variability in farm profit, increased. Assuming higher fertility and weaning rates could be achieved consistently, ewes with high-fecundity offer producers the potential to increase profit with decreased emissions.

Sheep of divergent genetic merit for wool growth do not differ in digesta kinetics while on restricted intakes 
I. De Barbieri, R. S. Hegarty, V. H. Oddy, M. C. Barnett, L. Li and J. V. Nolan

We hypothesised that as digesta retention time affects rumen microbial protein outflow, differences in digesta kinetics may contribute to genetic divergence in fleece weight of sheep. However, sheep of divergent genetic merit for wool growth differed in wool growth rate but not digesta retention time. Feeding level affected both wool growth and digesta kinetics consistently, irrespective of animal genetic merit.

Impact of severity of ruminal acidosis on feed-sorting behaviour of beef cattle 
T. J. DeVries, T. Schwaiger, K. A. Beauchemin and G. B. Penner

Beef feedlot cattle, fed high-grain diets with limited forage content, often experience ruminal acidosis challenges, particularly when transitioning from a forage-based diet. As theorized, it was found that greater experience of ruminal acidosis resulted in a greater change in dietary selection for higher-fibre dietary particles. The results provide further evidence cattle will alter their diet selection behaviour in response to rumen discomfort.

Effects of restricted time allocation to pasture on feeding behaviour, intake and milk production of dairy sheep rotationally grazing Italian ryegrass (Lolium multiflorum Lam) in spring 
G. Molle, M. Decandia, V. Giovanetti, C. Manca, M. Acciaro, G. Epifani, L. Salis, A. Cabiddu, M. Sitzia and A. Cannas

The effects of restricting time at pasture on intake and performance of dairy ewes are poorly known. To fill this gap, a study was conducted in rotationally grazing milked ewes, finding that time restriction below 6 h/day and depletion of herbage quality at the end of grazing period constrained intake and milk performance. Further studies are needed to evaluate the implications of these results at system level.

Rice straw, cassava by-products and tree legumes provide enough energy and nitrogen for liveweight maintenance of Brahman (Bos indicus) cows in Indonesia 
R. Antari, G. P. Ningrum, D. E. Mayberry, Marsetyo, D. Pamungkas, S. P. Quigley and D. P. Poppi

Indonesian smallholder farmers require cost-effective and accessible supplements to increase the liveweight and body condition score of Brahman cows fed rice straw-based diets. Cows fed rice straw supplemented with cassava by-products plus urea or a tree legume, were able to gain liveweight and maintain a body condition score of 2.2 on a 1–5 scale. Better supplementation strategies are required for cows to maintain a higher body condition score.

A systems approach to determine the effect of changes in gene expression in adipose tissue on productive and reproductive efficiency in dairy cattle 
K. Huber, A. Kenez, J. P. McNamara and S. L. Shields

The complex metabolic interactions that control efficiency of animal production requires the use of systems biology research and mathematical models. An existing metabolic model of metabolism in the dairy cow was expanded to include more detail in describing adipose tissue metabolism and reproductive processes. Changes in adipose tissue metabolism alterthe energy expenditure of the animal, which altered the degradation of steroids and changed the pattern of cyclicity.

Target feeding for improved smallholder beef production in the Mekong region: lessons from Cambodia and Lao PDR 
R. D. Bush, B. Page, T. Macdonald, J. R. Young, S. Nampanya, S. Suon, S. Khounsy, L. A. Henry, P. C. Thomson and P. A. Windsor

Increased demand for red meat throughout the Greater Mekong Subregion (GMS) presents smallholder cattle and buffalo farmers with an opportunity to supply better-quality animals to expanding regional markets. Cattle were target-fed introduced forages in Cambodia to gain 0.19 kg/day and over US$60 in value compared with traditional cut-and-carry feeding practices where animals lost 0.04 kg/day. To increase supply for the growing demand for red meat, as well as poverty reduction, an ongoing, multi-disciplinary extension program should be a priority for livestock improvement programs in the GMS.

Including essential oils in lactating dairy cow diets: effects on methane emissions1 
S. J. Meale, A. V. Chaves, T. A. McAllister, A. D. Iwaasa, W. Z. Yang and C. Benchaar

Methane emissions from ruminant livestock have increased five-fold over the past century, heightening efforts to investigate the mitigation potential of feed additives. This study found no effects of dietary essential oils on methane and carbon dioxide emissions from lactating dairy cows. Identifying dietary additives which can consistently reduce methane emissions without compromising animal performance is a primary focus of most mitigation strategies.

Productivity results and physiological response of the gastrointestinal tract of rabbits fed diets containing rapeseed cake and wheat distillers dried grains with solubles 
A. Gugołek, J. Juśkiewicz, P. Wyczling, D. Kowalska, J. Strychalski, M. Konstantynowicz and C. Zwoliński

Biofuel industry generates vast amounts of plant by-products, including rapeseed cake (RC) and distillers dried grain with solubles (DDGS). The aim of study was to determine whether RC and wheat DDGS can be used as components of diets for rabbits. Our study demonstrated that 5% RC can be incorporated into rabbit dietary as a substitute of soybean meal. Because the productivity of rabbits fed 2.5% of DDGS (with 2.5% RC) was comparable to the 5% RC, the incorporation of up to 2.5% wheat DDGS to a diet should also be taken as a dietary option. The higher content of DDGS (5%) in the diet deteriorated the growth of rabbits.

S. Indu, V. Sejian and S. M. K. Naqvi

The study was conducted to observe the impact of simulated heat-stress model on productive and adaptive capability of Malpura ewes. Compared with constant heat-stress models, the simulated model inflicts less severe physiological strain as evidenced by relatively lower changes in the heat-stress markers such as RR, RT and plasma cortisol. However, their growth and reproductive performance are compromised during the process of adaptation.

Márcia Cristina Araújo Santana, Bruno Ramalho Vieira, Diogo Fleury Costa, Paulo Henrique Moura Dian, Giovani Fiorentini, Roberta Carrilho Canesin, Gener Tadeu Pereira, Ricardo Andrade Reis and Telma Teresinha Berchielli

This paper is about the inclusion of ingredients of soybean origin in supplements and the frequency of supplementation of grazing cattle during the drier periods of the year, evaluating the effects on animal performance. The main finding was that frequency of supplementation did not affect the weight gain of cattle, but suggested that supplementation could be done 3 days a week opposed to daily, and would decrease production costs.

Effects of weaning beef cattle in two stages or by abrupt separation on nasal abrasions, behaviour, and weight gain 
Christian Lambertz, Peter R. Bowen, Georg Erhardt and Matthias Gauly

As an alternative to traditional weaning by abrupt separation, weaning beef calves in two stages by fitting nose flaps to prevent nursing before the final separation might reduce the stress response. Although two-stage weaning positively influenced the post-weaning behaviour of the calves and cows, the devices caused heavy irritations of the nasal septum. Therefore, the design of the anti-suckling devices and the period the devices are fitted should be modified in order to minimise nasal abrasions.

Evaluating rates of technology adoption and milking practices on New Zealand dairy farms 
J. P. Edwards, B. T. Dela Rue and J. G. Jago

Milk harvesting is a fundamental component of dairy farming, requiring significant labour input. Consequently, with increasing herd sizes, there is a constant drive to improve milking efficiency. Explaining differences in milking efficiency by monitoring milking practices and the adoption of new technologies can, therefore, be beneficial to the industry. The results of this work indicate the use of technology was associated with greater labour efficiency but the potential benefits of each technology require careful evaluation to ensure appropriate selection decisions are made by farmers to meet their requirements.

The search for solutions to safeguard animal performance and health while reducing antibiotic usage currently attracts worldwide interest. While certain feed additives such as probiotics and phytogenics show promising results, tailoring additive combinations as part of an overall efficacious dietary strategy is largely undeveloped. Our results support the concept of sequential or throughout probiotic and phytogenic administration as being beneficial for broiler performance and broiler antioxidant status, worth of further investigation.

In the arid zones of Mexico young kids graze/browse together with their mothers on rangeland. It is unknown if goat kids discern between forages, therefore the aim was to find out if 4-week-old goat kids display an efficient foraging behavior. Kids ingested a diet richer in nutrients than mature goats; thus, herbage selection seems to be shaped by physiological effort.

Effects of feeding various levels of full fat soybean extruded at high temperature on performance, serum components and intestinal morphology of broiler chickens 
Safa Zhaleh, Abolghasem Golian, Seyed Ali Mirghelenj, Avisa Akhavan and Abdollah Akbarian

The present paper reports on application of extruded full fat soybean (EFFSB) in broiler diet to identify its potential toward improving production performance criteria. The FFSB extruded at 170°C had acceptable protein solubility in KOH, indicating a good EFFSB. The latter in turn indicates an optimum balance between degradation of ANFs and maintaining the bioavailability of essential amino acids, hence having the potential to exert positive effect on blood metabolites and intestinal morphology of broilers at market age.

To improve the spermatozoa fertility, cryodamages must be decreased by using suitable diluents and cryopreservation. Therefore, the aim of this study was to investigate the effect of different levels of trehalose and glycerol on the freezing process of ram semen, when lecithin is used as cryoprotectant. It was concluded that simultaneous use of glycerol and trehalose had a desirable effect on motility of ram frozen–thawed sperm.

Re-used progesterone devices efficiently synchronise oestrus and ovulation after autoclaving process in Toggenburg goats during the breeding season 
J. M. G. Souza-Fabjan, C. A. A. Torres, A. L. R. S. Maia, F. Z. Brandão, E. Oba, M. J. Bertoldo and J. F. Fonseca

As protocols for oestrus synchronisation shortened the time of exposure to progesterone, CIDR devices were able to be reused; however, they can be a health risk. This study demonstrated that new and previously used (and autoclaved) devices are equally effective for synchronisation of oestrus and ovulation during the breeding season in goats. This approach decreases the cost of oestrus synchronisation program and makes it more economically feasible for producers.

Possible involvement of myo-inositol in the physiological response of broilers to high doses of microbial phytase 
A. J. Cowieson, R. Aureli, P. Guggenbuhl and F. Fru-Nji

Although myo-inositol is proportionately equivalent to phosphorus in phytic acid, its contribution to the observed beneficial effects of phytase in poultry and swine nutrition is obscure. Evidence is presented herein to show substantial increases in myo-inositol concentrations in the plasma of poultry in response to phytase addition. As myo-inositol has recently been shown to be an insulin-mimetic, links between insulin pathways, glucose uptake, protein accretion and exogenous phytase are drawn.

The αs1-casein is the most polymorphic milk protein and its genetic variants influence the quali-quantitative characteristics and the technological properties of the milk. This study investigates the genetic variability at the CSN1S1 in the Mediterranean buffalo. A significant association between the c.628C>T SNP and the protein percentage was found. This result offers useful indications for future applications of marker-assisted selection programmes.

Effects of two different forage sources on mammary gland growth, mammary cell turnover and activity in early lactation dairy cows 
Tong Qin, Haoyu Wang, Dengpan Bu, Haisheng Hao, Dong Wang and Huabin Zhu

The forage system is critically important to lactation performance in dairy cows. Our results suggested that the expression of IGF-1R in the mammary glands and the number of mammary cells is significantly affected by forage system, and this is closely related to the milk production in early lactation cows. This research provided the basis for better understanding of the molecular mechanisms of lactation regulation.

Micro-encapsulated sodium butyrate attenuates oxidative stress induced by corticosterone exposure and modulates apoptosis in intestinal mucosa of broiler chickens 

Under the conditions of intensive farming, it is very important to improve poultry health. The aim of this study was to investigate the effects of micro-encapsulated sodium butyrate (MSB)on oxidative stress and apoptosis in the intestinal mucosa of broilers and the main discovery was that dietary MSB can partially attenuate oxidative stress induced by corticosterone treatment and inhibit apoptosis of intestinal epithelial cells. This could confirm again that nutritional regulation of pre-slaughter stress through feed additives may provide a simple way to improve poultry health.

Dietary chromium picolinate of varying particle size improves carcass characteristics and insulin sensitivity in finishing pigs fed low- and high-fat diets 
A. T. Hung, B. J. Leury, M. A. Sabin, T. F. Lien and F. R. Dunshea

The effects of Cr in pigs have been equivocal. The aim of this study was to evaluate the effects of different-sized particles of CrPic in gilts; the results showed that small-sized particles CrPic improves carcass characteristics when pigs fed a high fat diet. Dietary supplement with small-sized particle CrPic can provide beneficial effects, particularly in high-fat diets.

The effects of chronic nitrate supplementation on erythrocytic methaemoglobin reduction in cattle 
I. Godwin, L. Li, K. Luijben, N. Oelbrandt, J. Velazco, J. Miller and R. Hegarty

Cattle fed nitrate risk methaemoglobinaemia, but with chronic feeding their red cells increase their ability to reduce methaemoglobin. In vitro studies suggest that phosphate plays a role in aiding the reduction of methaemoglobin and that the metabolic endpoint of red cells changes to maximise substrate availability for methaemoglobin reduction. It appears that both the animal and its rumen microbes adapt to nitrate feeding.

Association of carcass weight with quality and functional properties of beef from Hanwoo steers 
Dinesh D. Jayasena, Ki Chang Nam, Jong Ju Kim, Hyeonju Ahn and Cheorun Jo

Beef producers in Korea try to increase marbling in beef muscles due to higher consumer demand towards such meat. Increasing marbling through extended feeding eventually burdens stakeholders of the beef industry and this study showed that medium (375–425 kg) carcass weight was optimal for achieving superior beef quality. Medium carcasses provide more health benefits at lower cost.

Effects of duration of salt supplementation of sheep on rumen metabolism and the accumulation of elements 
Clive J. C. Phillips, Mohamed O. Mohamed and Paul C. Chiy

Excess salt in the sheep’s diet can impair digestion, but they may adapt to high concentrations in plants by reducing absorption. We found no evidence of adaptation, in fact their rumen developed a reduced ability to maintain a normal pH over time, with implications for accumulation of some elements in the brain and kidney. Thus farmers should beware exposing their sheep to high salt in their feed for prolonged periods.

An animal house study on utilisation of fresh tedera (Bituminaria bituminosa var. albomarginata and crassiuscula) by Merino wethers 
C. M. Oldham, D. Wood, J. Milton, D. Real, P. Vercoe and A. J. van Burgel

Bituminaria bituminosa is a drought-tolerant, perennial legume that has been used for centuries as a part of the mixed sward in grazing systems around the Mediterranean sea and ‘cut and carried’ to feed as hay to dairy goats in the Canary Islands; varieties albomarginata and crassiuscula, commonly known as tedera, are native only to the Canary Islands. In south-western Australia, tedera will likely be directly grazed as green plants to help fill the feed gap in summer–autumn, due to its drought tolerance and capacity to retain green leaves. . Sheep fed fresh tedera exclusively for 34 days readily consumed the forage and remained in good health, they maintained their liveweight (42.5 kg) and body condition (condition score 3) throughout the experiment.

Selection for residual feed intake affects appetite and body composition rather than energetic efficiency 
D. S. Lines, W. S. Pitchford, C. D. K. Bottema, R. M. Herd and V. H. Oddy

Feed costs are the largest single cost in any animal production enterprise with improvements in feed efficiency able to reduce feed costs. This study aimed to understand the basis for feed efficiency measured by residual feed intake and variation in maintenance requirements. The results obtained suggest that body composition, specifically fat deposition, is affected through inherent differences in feed intake or appetite rather than maintenance requirements.

Measuring blood stress indicators could be useful for improving animal welfare and meat quality. The current study measured various blood parameters from pigs under the standard pre-slaughter conditions using a portable analyser. Higher levels of blood lactate and glucose correlated with decreased pork quality. Therefore, measuring blood lactate and glucose could easily and quickly provide information about pork quality.

Whole-grain feeding for chicken-meat production: possible mechanisms driving enhanced energy utilisation and feed conversion 
Sonia Yun Liu, Ha H. Truong and Peter H. Selle

Whole-grain feeding regimes for chicken-meat production provide economic advantages by reducing feed costs while generating improvements in energy utilisation and feed conversion efficiency; however, the genesis of the performance improvements are not defined. The present paper considers the contexts in which these responses may be best realised. Identifying the drivers will enable the most appropriate WGF strategies to be adopted.

Monthly metabolisable energy feed requirements of crossbred ewes in accelerated and traditional lamb production systems 
N. M. Fogarty

Accelerated lambing potentially increases biological efficiency of lamb production and affects seasonal patterns of feed requirements. Metabolisable energy requirements were used to calculate dry sheep equivalents (DSE) and showed that crossbred ewes in accelerated lambing weaned 16–47% greater weight of lamb per DSE over 4 years than ewes in traditional systems. The increased efficiency of accelerated lambing requires a more consistent feed supply throughout the year.

Tedera is a perennial pasture containing secondary compounds that has the potential to be utilised in the farm systems during the summer-autumn feed gap and reducing supplementary feeding. In our study, we showed that tedera was fermented without any adverse effects on digestibility or fermentability. These findings give further support for pursuing tedera as a fodder for growing regions of Australia.

Combining wavelet and linear-regression methods to model the effect of available forage on daily grazing and lying activity of mature Bos indicus cows during summer months 
M. S. Gadberry, W. Whitworth and G. Montgomery

Wavelet and linear regression methods were used to model time-of-day changes in behaviour due to available forage. The study concluded decreasing forage availability resulted in greater lying activity from 1000 to 1300 and greater grazing activity from 1300 to 2100. Understanding the dynamics between forage supply and behaviour could provide decision tools incorporating behaviour into drought management decisions.

Y. Singh and V. Ravindran

The influence of pellet diameter and whole wheat inclusion on gizzard development and performance of broilers was investigated. Whole wheat and larger diameter pellets increased the energy utilisation and starch digestibility, but gizzard weights differed depending on the method of whole wheat inclusion. The data showed that improvements associated with whole wheat feeding cannot always be explained on the basis of gizzard development.

The primary goal of this study was to assess the usefulness of rye-containing dry mixes (modern rye cv. Visello) for pig fattening. Feeding the mixes in which a proportion of barley was replaced with the rye grain has yielded significantly better results than barley-containing diets in terms of carcass quality and price. These observations warrant further studies of different rye cultivars to determine their utility in intensive pig farming.

Pork makes a major contribution to worldwide meat consumption, and ways of improving meat quality are imperative. Variation in the rate of post-mortem pH decline is an important reason for variation in meat quality, but the mechanisms involved are not clear. In our research, we found that post-mortem energy status and metabolism might be important factors in the conversion of muscle to meat and might be important determinants of ultimate meat quality.

Dual-purpose wheat may be grazed by late-pregnant and lactating ewes during the winter in southern Australia. Results from two experiments with ewes grazing wheat crops during the lambing period identified that wheat forage may contain insufficient calcium, magnesium and sodium to meet ewe requirements. Providing a loose-lick mineral supplement to ewes can increase liveweight gain in twin-born suckling lambs.

The use of maize as a switch crop or the use of markets for roughage are the most efficient strategies to reduce financial risk of suckler cow farming. Applying a bio-economic optimization model we find that these strategies cause only low reductions of average gross margin. Our results also indicate that gross margin insurance is not attractive for farmers.

Algae are a novel protein source which could be grown on farm to provide a cheap protein supplement to cattle. Algae were compared to urea and sulfur as a nitrogen supplement and markedly increased intake and microbial protein production in cattle, more so than a simple urea and sulfur supplement. Algae are thus a new protein supplement which has the potential to markedly increase liveweight gain of cattle.

Effects of reduced dietary protein on performance and nitrogen (N) excretion were assessed to reduce the environmental impact of pig production. Pigs were given a control diet or a diet with reduced protein content, either with (LP1) or without (LP2) amino-acid supplementation. Compared with the control, N excretion was reduced (~18%) in LP1 and LP2, but the feed-conversion ratio was poorer, as was growth in LP2, but not LP1. This indicates the difficulty in maintaining consistently high performance when dietary protein levels are reduced.

High potassium (K) in the diet of sheep and cattle has been implicated in the incidence of milk fever and grass tetany (hypomagnesaemia). The aim of this study was to determine the effect of a high K diet on calcium (Ca) absorption in sheep. The results demonstrate that increased dietary K decreased Ca absorption and decreased magnesium (Mg) status of the sheep. Therefore, levels of both Ca and Mg should be considered when feeding high-K diets to ruminants, to reduce the risk of hypomagnesaemia and hypocalcaemia and to improve livestock health and productivity.

Lambs born in spring were weaned in summer when they began to graze natural pastures. In summer, natural pastures commonly present low protein content. Restricted grazing of natural pastures improved with legumes resulted in similar or better performance than supplementation with soybean meal. Including in the feeding plan natural pastures improved with high-protein forage species is an alternative as effective as the supply of soybean meal.

Natalie A. Browne, Ralph Behrendt, Ross S. Kingwell and Richard J. Eckard

Greenhouse gas emissions from Australian agriculture are currently at 15% of national emissions and mitigation research is an important way of showing farmers how they might reduce their agricultural emissions. This research uses farm management practices to examine if producing more product across an animal’s lifetime affects emissions and profitability on farm enterprises. The results show that the potential for greater profitability on farm enterprises is driven more by increasing production than from claiming carbon offsets.

Milking permission and milking intervals in a pasture-based automatic milking system 
N. A. Lyons, K. L. Kerrisk and S. C. Garcia

Extended milking intervals have a negative effect on milk yield and udder health. Analysis of cow traffic data from an automatic milking system found that previous milking refusal was not the main cause of extended milking intervals. These cows could be sorted to an area close to the dairy; however, management should focus on reducing time cows spend between milkings in any one pasture allocation.

Effect of inulin and mannan-oligosaccharides compared with zinc-bacitracin on growing performance, nutrient digestibility and hematological profiles of growing rabbits 
Y. A. Attia, R. S. Hamed, A. E. Abd El-Hamid, H. A. Shahba and F. Bovera

It is important to identify valuable alternative to antibiotics in rabbit production to control the problem of antibiotic resistance of bacteria. Mannanoligosaccharides and inulin are able to effect similar results to antibiotics in rabbit growth. Mannanoligosaccharides were more effective than inulin at improving rabbit performance during growing.

The leptin receptor is expressed in the Leydig cells of Merino rams, but its expression is not affected by long-term differences in the plane of nutrition 
blank image
J. Gil , P. Genovese , I. Sartore , A. Bielli , F. Montossi and C. Viñoles
pp. 981-986

Ram reproductive potential is affected by nutrition and its action at testicular level may be mediated by leptin, although the specific compartment expressing its receptor (Ob-Rb) remains uncertain. After 14 weeks of improved nutrition, we promoted histological changes linked to increased spermatogenesis, and found that the Ob-Rb expression in the Leydig cell cytoplasm was similar among treatments.

Polymorphisms of LHβ and GnRHR genes and their association with the number of embryos recovered in goats 
blank image
M. Z. Fu , G. Li and Z. Q. Zhou
pp. 987-991

The candidate-gene approach could identify genes influencing the superovulatory response. The study was to analyse associations between the number of embryos recovered and polymorphisms of LHβ and GnRHR genes and showed that two SNPs had significant effects on the number of embryos recovered. LHβ and GnRHR genes are potential markers for the number of embryos recovered.

pp. 992-998

Yolk hormones play an important role in the regulation of offspring development through maternal effects. In this study, we aimed to determine whether the enzyme 3βHSD1 has an effect on yolk progesterone; we found that 3βHSD1 in the follicular wall may play a key role in the accumulation of yolk progesterone. This finding may be used to improve the quality of offspring by further research.

Commercial producers should access available crossbreeding systems using existing swine breeds before application. In this study, the profits of terminal, rotational and rotaterminal cross were evaluated using three imported swine breeds in south-western China, and their profits were ¥3895.15, 3749.02 and 3317.33/sow, respectively. The results suggested terminal cross or rotaterminal cross should maximise effective use of heterosis and breed complementarity in China.

The effect of peri-conceptual grazing of live pasture on fetal numbers in unsynchronised ewes 
blank image
S. M. Robertson , B. J. King , M. B. Allworth , J. Rummery and M. A. Friend
pp. 1008-1015

Short-term elevated nutrition around mating is a potential means of increasing the number of lambs born to ewes. This study showed that ewes grazing live pasture for 7 days before and during the first 7 days of mating in autumn can produce more lambs than those grazing dead herbage. This method provides a simple, natural means of increasing lamb production.

Effects of organic and inorganic selenium supplementation during late pregnancy on colostrum and serum Se status, performance and passive immunity in Merghoz goats 
blank image
R. Kachuee , M. Moeini and M. Souri
pp. 1016-1022

Organic and inorganic Se supplementation would be useful for producers who raise animals in Se-deficient regions. There is higher efficiency of L-selenomethionin (Se-Met) than the sodium selenite (SS) supplement. The kids with adequate levels of Se obtain more maternal antibodies in colostrum. Both Se supplementations in pregnant goats improved Se status of goats and the newborn kids. The Se-Met supplement could have influenced passive immunity of kids.

Plantain (Plantago lanceolata L.) and perennial ryegrass (Lolium perenne L.) as pregnancy and lactation feed for ewes joined at 8 months of age

M. C. Raeside , Z. N. Nie , M. Robertson , D. L. Partington and R. Behrendt
pp. 1023-1029

Dry matter production and nutritive characteristics of the pasture feed-base during pregnancy and lactation are key drivers of ewe and lamb performance. A paddock-scale field experiment in Victoria, Australia, evaluated plantain as a forage alternative to perennial ryegrass for lambing ewes. There were rarely differences in forage or livestock performance between the forage species. Based on our experiment, there are no clear benefits of using plantain instead of perennial ryegrass for lambing ewes.

Effect of processing method on in sacco ruminal degradability of organic matter and nitrogen from canola seeds and in vitro intestinal nitrogen digestion of the in sacco residue 
blank image
S. A. Gunter , T. L. Springer , C. A. Loest and J. J. Goldman
pp. 1030-1038

Production of canola seed is increasing in the United States and alternate uses for seeds other than oil may be necessary in the future. On-farm use of whole canola seed for ruminant livestock production is discussed, but little is known regarding necessary processing to optimise digestion in grazing cattle. Grinding of whole canola seed should provide a viable protein supplement that requires minimal processing before feeding.

R. Rodríguez , G. de la Fuente , S. Gómez and M. Fondevila
pp. 1039-1046

Three tropical browse legumes were assayed in vitro to estimate the proportion of the response in different parameters when tannins are inactivated with polyethylene glycol (biological effect). Tannins differing in their amount or chemical nature may have different biological effect and this may be an easy and rapid index of the microbial fermentation pattern of tropical feeds.

Effects of rice straw versus wheat straw as ingredients in a total mixed ration on intake, digestibility and growth of Holstein heifers 
blank image
R. E. Rauch , G. Cun , G. A. Nader and P. H. Robinson
pp. 1047-1055

Rice straw has generally not been considered as a feed for dairy cattle in the developed world, partly due to its tough physical character. While our results confirmed the lower nutritional value of rice vs. wheat straw, they demonstrated the practical utility of using energy restriction/re-alimentation feeding systems to increase heifer growth efficiency.

Ruminal pH and whole-tract digestibility in dairy cows consuming fresh cut herbage plus concentrates and conserved forage fed either separately or as a partial mixed ration 
blank image
J. S. Greenwood , M. J. Auldist , L. C. Marett , M. C. Hannah , J. L. Jacobs and W. J. Wales
pp. 1056-1063

Feeding high amounts of supplements to grazing dairy cows as a mixed ration containing maize grain can increase milk production responses compared to traditional systems of feeding supplements. An experiment showed that cows fed PMR had higher ruminal pH than cows fed grain and silage separately, but that this did not result in any changes to whole tract digestibility. Benefits of PMR systems are presumably related to increased intake of both supplement and pasture rather than improvements in digestibility.

H. S. Mun , S. T. Ahmed , J. A. Hwang , Y. J. Kim and C. J. Yang
pp. 1064-1074

The combination of medicinal plants and probiotics is a new possibility for addition to cattle feed supplements, as it provides complementary antioxidant and antimicrobial activities and lacks side effects. This study aimed to ferment Alisma canaliculatum with multi-strain probiotics and investigate its effects on Hanwoo steers. Alisma canaliculatum probiotics showed a potential role in improving growth performance, carcass characteristics and meat oxidative stability of beef cattle.

pp. 1075-1083

Automatic monitoring of farm animals could be a useful tool in large-scale husbandry. This study aimed to evaluate the relationship between pig activity and environmental parameters in a piggery by means of image analysis. Climate variations affected occupation and activity indices of animals, which could be used as indicators of the of pigs’ physiological status change in response to external inputs.

pp. 1084-1090

Aggression in pigs is a serious issue in pig farming since it poses enormous welfare and economic problems. This study aimed to use acoustic-reward learning as a new approach to reduce the incidence of aggression among pigs. The presented method showed some potential to reduce the frequency and duration of aggressive actions among young piglets.

pp. 1091-1094

The main purpose of this study was to find out the effect of season on chemical composition and microbial quality of milk and yoghurt produced from sheep milk. Data revealed that the quality of yoghurt samples made in winter was better than those made in summer; so the marketability of dairy products could be affected by season.

We extracted acetic acid-soluble and pepsin-soluble collagen from antler velvet. Thermal denaturation temperature and peptide mapping were similar between antler and porcine type I collagen. There is a possibility of using collagen extracted from elk antler velvet as an alternative to using porcine or cattle collagen for industrial purposes.

J. P. Edwards , J. G. Jago and N. Lopez-Villalobos
pp. 1102-1108

Milk harvesting is a fundamental component of dairy farming and affects all parts of the business from cows to people and financial performance. Previous researchers have investigated strategies to improve the efficiency of different components of milking, without quantifying the effect that these strategies, or combinations of them, may have on the overall milking system. This study analysed the effect of rotary size, platform speed, cluster attachment time, milk yield and end-of-milking criteria on cow throughput, operator efficiency and return on investment.
