AN24186Effects of by-product feed inclusion in a grass hay-based diet on nutrient disappearance, total gas and methane production, rumen fermentation and protozoal populations in an artificial rumen (RUSITEC)

S. Robinson, P. Tamayao, A. Saleem, K. Ominski, T. McAllister, G. Crow, K. Wittenberg and E. J. McGeough 0000-0001-7763-3306
 

As part of the natural process of feed digestion, cattle produce methane, which is a potent greenhouse gas. This study evaluated the impact of fat in grass hay-based cattle diets by including by-products from cereal/oilseed processing and determining the impact on methane emissions. Overall, higher dietary fat reduced methane emissions; however, it reduced digestibility of the diet, which is an important consideration for its impact on animal productivity.

AN25046Managing predators on livestock producing properties in South Africa and Western Australia – producer perspectives

T. L. Kreplins 0000-0002-6439-7858 and H. A. Melville
 

South Africa and Western Australia have long histories of livestock production and predator management, which impacts livestock productivity and viability. A survey of producers in both regions found farm sizes to be generally similar. More predators reside in South Africa, and as poison use is illegal, most farmers rely on shooting as their primary control method. Losses to predators are higher in South Africa, where predator management is responsive rather than proactive, unlike the Recognised Biosecurity Groups in Western Australia.

AN24415Mapping the use of insects in animal feed: scientific and technological data of Tenebrio molitor, Hermetia illucens, and Zophobas morio

Jade Silva Oliveira 0009-0002-4170-4760, Camila Duarte Ferreira Ribeiro, Carolina Oliveira de Souza 0000-0002-8028-5418 and Cláudio Vaz Di Mambro Ribeiro 0000-0001-8676-3225
 

Tenebrio molitor, Hermetia illucens, and Zophobas morio are species rich in nutrients essential for animal nutrition. However, it is still unclear whether these species are studied with the same frequency, which areas of animal production benefit the most from their use, and the main objectives of the most recent studies. Identifying these knowledge gaps can support the development of innovative research on the use of insects in animal feed.

AN25047Effect of methionine and lysine supplementation on performance and intestinal morphometrics of finisher broiler chickens fed diets containing processed cassava peel meal

Tolulope O. Adebowale 0000-0002-7325-5691, Muhammed A. Arowolo, Mukaila Adekola, Tolulope Adeleye and Oyegunle E. Oke 0000-0002-9425-4217
 

Researchers have been exploring sustainable feed alternatives for broiler chickens due to the rising costs of conventional feed ingredients and environmental footprints associated with agricultural by-products. This study investigated the use of processed and fortified cassava peel meal as a replacement for corn in broiler diets and found that it supports growth and reduces production costs without compromising gut health. However, some morphological alterations were observed in the liver and intestinal tissues of the chickens, which require further investigation.

AN25057Economic analysis of benefits from grazing unharvested standing lupin crops in a mixed farm enterprise in south-west Western Australia

Amelia Gooding 0009-0008-1717-7626, Serina Hancock, Andrew Thompson 0000-0001-7121-7459 and John Young 0009-0009-5557-5585
 

In the south-west of Western Australia, weaned lambs typically graze dry pastures and crop stubbles from late spring to autumn, which limits growth rates without supplementation and can contribute to ill-thrift and mortality. This study tested whether incorporating grazing of standing lupin crops improves whole-farm profitability. Grazing lupins on 7% of the farm area increased profitability by almost A$30,000 (A$200/ha), primarily by increasing stocking rate. Across a range of crop yields and prices, grazing was always more profitable than harvesting.

AN24154Predicting weaning weight in Hair goat kids: a comparative analysis of tree-based machine learning approaches using environmental and herd data

Necati Esener 0000-0002-2773-3234 and Yavuz Kal
 

We applied tree-based machine learning techniques to predict weaning weight in Hair goat kids, offering a fresh approach to goat farming. We used these tree-based machine learning models to analyze a variety of data sources, such as herd features and environmental factors like weather and geography. We found that these methods achieved strong predictive performance, suggesting that incorporating diverse environmental data into weight prediction models can help goat farmers make better decisions, especially with the challenges posed by climate change.

AN25092Growth curves of three broiler chicken strains fed diets of different nutritional densities

Josiane Carla Panisson, Isabella de Camargo Dias 0000-0003-0375-2462, Marley Conceição dos Santos, Leopoldo Malcorra de Almeida, Everton Luis Krabbe, Alex Maiorka and Simone Gisele de Oliveira
 

The purpose of this study was to evaluate the growth curves of three broiler chicken strains and the effects of different dietary nutritional densities on growth performance. The Gompertz model explained 99% of the variation in chicken weight. Chickens fed a regular diet had slower maturation and lower growth rates, whereas Strain A showed lower bodyweight and feed intake than did Strains B and C. Higher nutritional density diets increased growth rates, but all strains exhibited similar allometric growth patterns.

AN24245The potential of various phenotypic traits to predict feedlot production in cattle – a systematic review

Andreas H. R. Hentzen and Dietmar E. Holm 0000-0002-9340-6573
 

Beef cattle have been improved over a long time, mostly by subjective visual appraisal, but are these phenotypic traits predictive of feedlot production potential? This review investigates evidence of an association between phenotypic traits and feedlot production, and found valuable evidence in the literature of a number of traits that are associated with production outcomes. This provides the foundation for the establishment of precision farming systems based on individual animals’ production potential.

AN25081Effects of almond hulls on the chemical composition and in vitro ruminal protein degradation of lucerne silage

Selim Sirakaya 0000-0003-2733-1726 and Selma Büyükkiliç Beyzi 0000-0002-4622-0645
 

Almond hulls are a significant by-product produced in quantities roughly double that of the kernel. The elevated tannin concentration is a limiting factor in their application in food and feed. Incorporating almond hulls into lucerne silage enhances the protein utilization efficiency of lucerne while reducing the tannin content in the hulls. Incorporating almond hulls into lucerne silage provides a dual advantage.

AN24358Insights into the pathogenesis of catastrophic spontaneous humeral fractures in first-lactation dairy cows

A. S. Wehrle-Martinez 0000-0002-3515-9164, K. E. Lawrence, P. J. Back, C. W. Rogers 0000-0002-4253-1825, M. J. Gibson 0000-0001-5970-4289 and K. E. Dittmer 0000-0002-1813-2197
 

Catastrophic spontaneous humeral fractures in young dairy cows have introduced significant challenges to New Zealand’s dairy industry, affecting animal welfare and farmers’ livelihoods. This review identifies poor bone formation and excessive bone removal as likely key risk factors leading to osteoporotic bones that fracture. Ensuring cows receive proper nutrition during key growth periods might help prevent these fractures and support a healthier, more productive dairy industry. Further research is essential to fully tackle this issue.

AN24340Impact of tree integration in crop–livestock systems with varying nitrogen rates

Luiza de Souza Carneiro, Luiza Chiezi Mendes, Debora Rodrigues, Vanderley Porfírio-da-Silva and Laíse da Silveira Pontes 0000-0002-3906-3047
 

Incorporating trees into crop–livestock systems (ICLS) plays a vital role in mitigating climate change by sequestering carbon in plants and soil. Our study showed that integrated systems can yield up to 573 kg/ha in areas typically fallow in winter; however, integrating beef heifers grazing cool-season grasses with immature Eucalyptus grandis trees negatively affected forage production, animal performance and tree quality. These results highlight the need for careful selection of trees, planting density, and arrangement to optimize the benefits of ICLS.

AN24303Metagenomic comparison of the microbial load colonizing lucerne hay and gum astralagus (Astragalus glycyphyllos) in ruminants

Mehtap Güney 0000-0002-0613-3600 and Sükrü Önalan
 

In this study, the digestion, fermentation profile and the microbiota associated with two different quality roughages (Astragalus glycyphyllos and lucerne hay) in the rumen were investigated in vitro. The composition and diversity of the microbiota colonizing the rumen significantly affect the digestion and fermentation of feeds, and thus the growth performance of animals. It was observed that these results are very important in terms of improving the efficiency of nutrient utilization of roughages in the desired direction.
