AN24091Physical treatment and protease or probiotic supplementation and feather meal digestibility by broilers
Feather meal (FM) is a major by-product of the poultry industry and is potentially a valuable source of crude protein and amino acids. However, the major constraint to its use is the feather protein keratin that reduces FM digestibility. The aim of this study was to explore technologies to improve FM digestibility.

AN23394Antibacterial properties of oil extracts of black soldier fly larvae reared on bread waste
The concern over the spread of antimicrobial resistance has prompted a search for alternative solutions. Black soldier fly larvae extracts possess natural antibacterial properties that can potentially inhibit bacterial growth. Rearing black soldier fly larvae on a bread waste-based substrate enhanced their lauric acid yield, resulting in significant antibacterial efficacy against E. coli; hence, incorporating larval oil into animal feed holds the potential for reducing antibiotic drug usage.

AN23403Incubation temperature affects growth and efficacy of white-rot fungi to improve the nutritive value of rice straw
White-rot fungus technology can revolutionise the utilisation of rice straw, because it enhances its quality by breaking down rigid components and boosting nutritional value. Investigating the temperature tolerance of these fungi is crucial for the practical application process, ensuring their effectiveness in diverse enviromental conditions and promoting their use in livestock feed. Unlocking their potential can increase the utility of this abundant by-product, contributing to environmental sustainability and agricultural productivity.

AN24035The reproductive performance of phosphorus-deficient mature cows improved rapidly when given supplementary phosphorus in the Victoria River District of the Northern Territory
This study investigated how long it takes for the performance of phosphorus (P)-deficient mature cows to improve once they are supplemented with P, and whether their long-term performance is compromised by P deficiency early in life. The performance of P-deficient cows improved to be similar to that of P-adequate cows within a year of P supplementation commencing. However, P deficiency early in life did have some residual stunting effects, resulting in lower hip height and liveweight.
AN23352Environmental impacts of Australian pork in 2020 and 2022 determined using lifecycle assessments
This study assessed the environmental impacts of Australian pork, and is the most comprehensive (70–72% industry) of its kind in Australia. Eutrophication potential was generally lower than in international pork production. The rate of environmental improvement was slow compared with historic trends. Covered pond, litter-based and outdoor systems produce pork associated with lower greenhouse gas emissions. Australian pork has significant potential to further reduce environmental impacts.

AN23398Strengthening the role of innovation brokers in the livestock advisory services system of Pakistan
A well-functioning farm advisory services play a vital role in the improvement of livestock sector in low-income countries. We explored the ways in which capacity building through a particular training and professional-development intervention can lead farm advisors to act as innovation brokers within the advisory services system of Pakistan. The results are highly instrumental in strengthening farm advisory services and the role of farm advisors in low-income countries to support farmers in improving their livelihoods.

AN23109Effects of melatonin implants on reproductive performance in sheep: a systematic review and meta-analysis
This study, evaluated the effect of melatonin on reproductive performance in sheep via meta-analysis. Pregnancy rate, lambing rate and litter size were used for reproductive performance parameters. Effect sizes of reproductive performance parameters were calculated according to breeds, production characteristics and seasons. The positive effect of melatonin was found greater in the non-reproductive period than in the breeding period for the three reproductive performance traits examined. This comprehensive research examined the effect of melatonin on sheep according to different factors.
AN23419Cow age, resilience and productivity of cow–calf systems
The sufficient length of the cow’s lifetime in the beef cattle herd allows to mitigate problems in the cow–calf systems generated by the reduction in food availability. The intermediate age (6 years) of culling the cows allowed better resilience of the herd, after restriction (50% or 75%) of energy during 60 days pre- and 60 days postpartum for the cows. The intermediate lifespan of cows allowed for better resilience and productivity in cow–calf systems.
AN23142Milk yield and feeding behaviour responses to two flat-rate levels of concentrate supplementation fed over a period of 8 months to cohorts of grazing dairy cows, differing in genotype, bodyweight, or milk yield
In pasture-based dairy systems little is understood regarding production responses or pasture substitution with different amounts of concentrates fed. Cohorts of cows were selected on contrasting differences for three parameters and fed concentrate at two flat-rate levels, while milk yield and feeding time were monitored. Contrasting responses were found between cross-breed and Friesian cows. Differences between cohorts demonstrated potential for targeted concentrate feeding to contrasting cohorts of cows, and the need to consider both marginal milk response and pasture intake.

AN23407Identifying high-value tactical livestock decisions on a mixed enterprise farm in a variable environment
Under Australia’s renowned climate variation, it is profitable for farmer to implement short-term tactical management adjustments in response to the unfolding weather conditions. This paper has identified and quantified optimal tactical livestock management for different weather-years for a mixed-farming system in the Great Southern region of Western Australia.

AN23287Effects of a blend of acidifiers added continuously to the drinking water of nursery piglets
Post-weaning period causes drastic changes in piglets. Therefore, there is a need to investigate strategies to improve the general health of the animals. The administration of a blend of acidifiers to reduce the pH of the piglets’ drinking water has shown interesting results, but still needs further investigation. Our results showed a reduction in mortality and an improvement in beneficial bacteria, which is reflected in animal welfare. These findings have provided information on farm conditions and scientific issues.
AN23013Red propolis extract reduces the lipid oxidation of lamb meat
Red propolis extract was offered at increasing levels to feedlot lambs and we observed that the animals’ carcass weight and physico-chemical parameters of the meat were not influenced by these treatments. Furthermore, the inclusion of 7 mL/day of extract in lamb diet was enough to reduce the oxidation of lamb meat, and also improved the lipid profile. We recommend the inclusion of 7 mL/day of red propolis extract in the diet of feedlot lambs.
AN23354Dietary chromium-methionine supplementation and broiler (22–43 days) responses during heat stress. 2 - Physiological variables, and heat shock protein 70 and insulin-like growth factor-1 gene expression
In the challenging world of broiler farming, the use of organic trace minerals sheds light on ways to improve the performance of heat-stressed chickens. Chromium–methionine (CrMet) supplementation has significant impacts promoting growth, regulating hormones, and altering genetic activity in broilers exposed to heat stress. CrMet supplementation supports animal health and nutrition for a more robust broiler production.
