AN24102Average daily gain in lambs grazing mixed annual forage species compared with single species and relationship to feed on offer

E. H. Clayton 0000-0002-3302-3781, H. Fahey, P. Tyndall, R. Lowrie, B. Xu, F. Ataollahi 0000-0002-6538-8566 and M. R. Norton 0000-0003-2649-5307
 

Annual forage crops provide high-quality fodder for livestock during autumn and winter feed-gaps in south-eastern Australia. We investigated potential animal-production benefits of grazing mixed annual forage crops. Average daily gain was lower for female, but not male, lambs grazing brassica only than for those grazing forage mixtures. The low rumen pH when lambs grazed brassica only could have been associated with subacute rumen acidosis. Future studies should assess the effect of forage mix on fibre degradation and growth rates over a longer grazing period.

AN23157Undegradable dietary protein limits growth and carcass yields in crossbred Boer kids fed Desmanthus hay or Rhodes grass (Chloris gayana) hay supplemented with urea and/or cottonseed meal

A. Aoetpah 0000-0002-4941-3813, C. Gardiner, B. Gummow, A. Mialon and G. Walker 0000-0002-5050-9468
 

Growth and carcass weight of meat goats on tropical pastures is determined by forage, and especially grass, quality. Supplementation of urea or cottonseed meal in Australian farms is common, but Desmanthus, as a shrub tropical legume that is rich in true protein, was also found to greatly increase bodyweight and yield heavier carcasses when fed to Boer goats. More work is required to identify alternate sources of true protein in tropical regions.

AN24138Prediction of the apparent ileal digestible amino acid contents of canola meal for broilers from crude protein content

X. Li 0000-0003-3109-5789, Y. M. Sun 0000-0002-9887-2303, D. Zhang, K. H. Huang, V. Ravindran and W. L. Bryden 0000-0002-7187-4464
 

Canola meal (CM) is a potentially important protein source for poultry. The amino acid profile of CM is reasonably well balanced, but digestibility of amino acids is key to the nutritional value of CM. Amino acid analysis and in vivo digestibility assays are costly and time consuming. The aim of this study was to determine whether the digestible amino acid content of CM could be deduced from its crude protein content, which is routinely determined.

AN23402Regional differences in beef cattle trade and movements associated with the COVID-19 pandemic in Australia

Joshua Aboah 0000-0003-1000-2109, Peggy Schrobback, Stephen McFallan and Dianne Mayberry 0000-0003-1584-8066
 

Despite the COVID-19 restrictions, agricultural activities were permitted to continue as essential services in Australia. This study showed that most regions in Australia did not experience significant changes in farm-level decisions concerning beef cattle movement and trade during the COVID period. Instead, minor adjustments were made to address the demand changes. The findings show the effectiveness of government policies in response to a disease outbreak like COVID.

AN23424Probiotics effects on the growth performance and meat quality of broiler chickens

Nazerke Begdildayeva 0000-0003-3302-5215, Aynur Gul Karahan 0000-0001-7625-5868, Askar Kondybayev, Aliya Kudaibergenova, Alina Nurgazina, Nurlan Akhmetsadykov, Aikerim Ospanova and Shynar Akhmetsadykova
 

This study examined the effectiveness of probiotics derived from fermented camel and mare’s milk products (shubat and koumiss) in Kazakhstan for improving broiler chicken production. Several probiotic strains had a significant effect on body and carcass weights, and average daily gain and feed conversion ratio were also improved. Considerable presence of these traditional fermented dairy products in Kazakhstan offers a promising opportunity for the creation of locally derived probiotics specifically designed for poultry use. This potentially enables the adoption of more environmentally friendly and specialised broiler-farming practices in the area.

AN23406Advances in smallholder large ruminant production and profitability in Southeast Asia over the past decade – lessons from the Mekong region: a review

Russell D. Bush 0000-0003-4252-039X
 

Global demand for protein in the form of red meat is growing, especially in Southeast Asia, with income and population growth driving an increase in beef consumption. To meet this demand advances in smallholder large-ruminant production and profitability have been achieved. However, to achieve regional food security ongoing challenges and opportunities need to be addressed.

The management of heat stress is an increasing topic of interest in pork production, especially during summer. This study approaches nutritional management to mitigate the negative impacts of environmental temperature on pork production and meat quality by supplementing selenium and vitamin E in pigs’ diets, along with organic acid in drinking water. The results of this study suggest that during cool seasons, supplementing antioxidants and organic acids in grower-finisher’s diets may be unnecessary, reducing the feed cost.

AN23206Nutritive value and multi-mycotoxin occurrence in feeds and milk of dairy cattle

Amal Mannai, Cristina Juan, Jordi Manes and Hichem Ben Salem 0000-0002-4806-4578
 

The safety and nutritional quality of milk for human consumption depends on the quality of the feed sources consumed by dairy cattle. Our study has shown that mycotoxins, harmful toxins, detected in some feed sources (e.g. forage silages, hay and concentrates) could be transferred to milk. Strategies for efficient management of feed sources should be developed and the transferability of mycotoxins to milk should be controlled to ensure that the food supply chain is safe and free from harmful toxins.

AN24073Assessing input efficiencies of specialised milk farms in the EU by using a non-radial DEA approach

Bülent Miran 0000-0001-6229-3740
 

Understanding input efficiency in specialised milk farming is crucial for enhancing sustainability and productivity in the European Union (EU) dairy sector. This study addressed the problem of inefficient resource utilisation in EU milk farming, discovering that countries such as Ireland and the Netherlands achieve full efficiency, whereas others have significant potential for improvement. The findings indicated that improving resource efficiency can lead to significant cost savings, environmental benefits, and increased competitiveness within the dairy industry.

AN24070Growth rate of male Bali cattle (Bos javanicus) fed leucaena and rice straw diets with increasing levels of cassava

  Dahlanuddin, L. A. Kariyani, T. S. Panjaitan, R. A. Putra, K. J. Harper 0000-0002-3443-6692 and D. P. Poppi
 

Supplementing Bali cattle rations in leucaena-based smallholdings with locally available cassava as an energy source, provides an opportunity to increase cattle live weight gain, extend the utilisation of leucaena and increase farmer profitability. Weight gain and profitability were maximised up to 45% cassava, but higher levels reduced feed intake, average daily gain and income over feed costs. Feeding cassava meal to leucaena-based diets is an important strategy to preserve leucaena as well as to increase profitability and meat production nationally.

The purpose of this study was to investigate the effects of flock age and egg weight on egg characteristics, incubation traits, hatchling weight, and initial offspring performance. Eggshell thickness and albumen height were lower, but albumen weight, yolk weight, and percentage of yolk were higher in eggs laid by older broiler breeders. Feed intake, bodyweight, and feed consumption rate were affected by the age of the hens and egg size.

AN23385A narrative review of factors affecting the welfare of dairy cows in larger Australasian pasture-based production systems

Megan Verdon 0000-0002-3971-4161 and David S. Beggs 0000-0001-5519-9123
 

Pasture-based dairies of the future are likely to be bigger, have higher stocking rates and feed more concentrate. This review uses the five-domains framework to consider risks to the welfare of dairy cows in these larger pasture-based systems. Risks to cow welfare are broadly categorised as (1) emerging welfare risks that can be managed, (2) emerging welfare risks that require research to be managed, or (3) persisting and/or exacerbated welfare risks. Suggestions are made for future research, development and extension.

AN24057Phytase super-dosing modulates bone parameters and the concentration of the calcium epithelial carrier calbindin-D28k in quails (Coturnix coturnix japonica) under thermal stress

A. G. Ribeiro 0000-0001-6730-0209, R. S. Silva 0000-0001-9988-4755, F. S. Costa 0000-0003-2763-4348, E. G. Silva 0000-0002-1123-086X, J. E. Santos Ribeiro 0000-0001-9493-6392, E. P. Saraiva 0000-0001-9461-1723, F. G. P. Costa 0000-0003-4075-1792 and R. R. Guerra 0000-0001-8226-8606
 

Thermal stress induces significant changes in the bioavailability of minerals, especially calcium, compromising egg production and egg quality in quails. The use of additives becomes necessary to optimise nutrient absorption and mitigate the negative impacts of high temperatures. Phytase stands out as it breaks down phytate molecules, releasing vital nutrients such as calcium. It also helps combat the effects of thermal stress on the calcium transporter calbindin-D28K. This optimisation consequently enhances calcium absorption for use in egg production.
