AN24084Selection for growth rate at pasture in Angus cattle results in heavier cattle that eat more in the feedlot

R. M. Herd 0000-0003-4689-5519, V. H. Oddy, P. F. Arthur and M. B. McDonagh
 

Selection for growth rate is a powerful tool to alter beef cattle performance but the evidence for an improvement in feed efficiency is equivocal. This experiment found that selection for faster growth in Angus cattle resulted in heavier cattle that ate more in the feedlot, with no evidence of improvement in feed efficiency. Breeding programs that place emphasis on growth rate need to be cognisant of the proportional increase in feed requirement by bigger animals.

AN23256Fermentation profile and chemical composition of Mombasa grass silage treated with chitosan and microbial inoculant

Mariana Campana 0000-0003-1795-7928, Jozivaldo Prudêncio Gomes de Morais 0000-0001-8418-2224, Thainá Moreira Garcia 0000-0003-3517-6404, Estefani Capucho 0000-0001-5019-4251, Marjorye Nunes 0000-0003-2687-8906, Jesus Alberto Cardoso Osório 0000-0002-6824-0946, Francine Basso Facco 0000-0001-8182-9766 and Tiago Antonio Del Valle 0000-0001-8093-7132
 

The ensiling process presents losses that are associated with the fermentative profile, resulting in lower nutritional value and lower aerobic stability of silages. The study evaluated the effects of adding chitosan and microbial inoculants to Mombasa grass (Megathyrsus maximus) silage. Chitosan altered some variables of the fermentation profile, but the treatments did not show a relevant effect on fermentation losses, chemical composition, and aerobic stability.

AN23314Can condensed tannins improve fermentation patterns and the nutritive value of sorghum silage?

E. J. O. Souza 0000-0002-2206-414X, J. M. C. S. Rodrigues 0000-0001-8434-2451, J. R. C. Silva 0000-0002-3496-4241, T. R. Torres 0000-0002-0739-0115, M. V. F. Santos 0000-0002-7374-0910, D. K. A. Silva 0000-0002-9024-1507, G. C. Sobral 0000-0002-4583-8822, E. L. Santos Neto 0000-0002-6815-7042 and O. F. Oliveira 0000-0001-8766-7040
 

Tannins are secondary compounds that act to protect proteins from microbial degradation. Affinity between tannins and proteins is due to the presence of multiple phenolic hydroxyl groups in tannins, which promotes an easier connection with proteins. Tannins can decrease proteolysis in silage, inhibiting microbial action, through the protein-bound linkage in the ensiled mass. Thus, it is recommended to include of tannin as an additive in sorghum silage to improve fermentation patterns, diminish aerobic deterioration, as well as improve digestibility.

Patricio D. Palacios 0000-0003-0194-8373, Isabel Ortiz 0000-0002-2479-498X, Jesús Dorado 0000-0002-4310-7663, Manuel Hidalgo 0000-0001-7830-7422, Juan Ramón García Díaz 0000-0002-2966-7824 and Andrés Gambini 0000-0002-3652-2068
 

This study explores the impact of zinc supplementation to improve the quality of cooled equine semen, addressing a crucial aspect of genetic preservation in horses. The findings showed that adding various concentrations of zinc to the sperm does not significantly enhance sperm quality during cold storage and concentrations exceeding 3 mM had detrimental effects. These findings challenge the common belief of the protective role of zinc in sperm preservation, contributing valuable insights for the equine breeding industry.

AN23255Human resource management practices on Irish dairy farms: an exploratory study

Thomas Lawton 0000-0001-7022-039X, Monica Gorman 0000-0001-8883-3530 and Marion Beecher 0000-0001-5161-3489
 

The dairy industry’s recent growth in Ireland has resulted in a high demand for additional workers, increasing the requirement for farmers to be skilled in Human Resource Management (HRM). This study identified that the adoption of HRM practices is influenced by farm characteristics, in particular herd size, the number of employees on the farm. This study has contributed insights into the prevalence of specific HRM practices on Irish dairy farms, and indicated that there is a significant scope for improvement. A novel aspect of this study was the focus on the potential factors that influence the adoption of HRM practices on Irish dairy farms. The findings of this study could be used by agricultural advisors and those working in HRM to provide tailored advice to support dairy farmers and other small business owners in managing their employees.

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

Mung Kwan Shu, Cheuk Ming Li, William Eduardo Furtado, Qianjun Huang, Sophie St-Hilaire and Ákos Kenéz 0000-0002-9041-3452
 

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.

AN24035The reproductive performance of phosphorus-deficient mature cows improved rapidly when given supplementary phosphorus in the Victoria River District of the Northern Territory

T. J. Schatz 0000-0003-1392-3675, M. N. Hearnden and C. Maxwell
 

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

M. A. Copley 0000-0002-9748-3197, E. J. McGahan, K. McCormack and S. G. Wiedemann 0009-0004-7060-0404
 

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.

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.
