AN24297Genetic parameters and response in conception, litter size and ewe rearing ability following 35 years of divergent selection for number of lambs weaned

C. L. Nel 0000-0002-3329-4928, A. A. Swan 0000-0002-9648-3697, K. Dzama and S. W. P. Cloete 0000-0002-4548-5633
 

A high reproduction rate in ewes depends on successful conception, giving birth to multiples and successfully rearing them to weaning. Genetic selection is often based on the sum of these components by counting the number of lambs weaned. This study shows that this approach can be viable, but argues for the use of the individual components, so that a measure of lamb mortality is directly defined.

AN25192Grazing behaviour and nutrient intake of dairy cows is affected by milking order and daily time at pasture

M. L. Douglas 0000-0002-4709-4572, M. M. Wright 0000-0001-9910-2784, J. W. Heard, V. M. Russo, G. L. Morris, P. S. Alvarez-Hess, M. C. Hannah, K. Giri, W. J. Wales and M. J. Auldist
 

Milking order on pasture-based dairy farms is consistent within herds and can negatively affect the quantity and nutritive characteristics of the pasture available to cows that return to the paddock later. This, in turn, influences grazing behaviour and milk production. This research highlights that cows that arrive back to the paddock later spent less time ruminating and had lower milk yields than early-milked cows, resulting in lower farm profit. Quantifying these data allows for future research investigating potential mitigation strategies.

AN25206Quantitative methodologies to assess sleep, wellbeing and physical health in dairy farm workplaces

C. R. Eastwood 0000-0002-1072-5078, J. P. Edwards 0000-0003-4220-7408, K. Dale, B. Kuhn-Sherlock and L. S. Hall 0000-0002-8338-0795
 

Studies on farm workplace practices often focus on qualitative rather than quantitative measures of change. We developed methodologies to measure changes in sleep, wellbeing and health among farmers implementing different milking schedules, and provide insights to aid in the future assessment of farm workplace changes. Results from this study provide unique quantitative measures of farmer sleep patterns and wellbeing factors, as well as an example of the methodologies that can be applied in evaluating farm workplace initiatives or interventions.

AN25184Feeding concentrate pellets to early-lactation cows consuming spring ryegrass pasture did not reduce methane emissions

K. Garrett 0000-0003-4282-3614, E. Stubbs, E. Minnee, K. Verhoek and J. Kay
 

This study evaluated the impact of offering supplementary concentrate feed at 4 kg DM per day to early-lactation cows consuming spring pasture. Supplementation increased dry-matter intake and milk solids, with a tendency for 5% higher daily methane emissions, but no reduction in methane yield or intensity. The role of supplementary feed in GHG mitigation requires further evaluation across diets, feed types and amounts, and whole-farm emissions and profitability.

AN25090Analysis of adoption of genetic tools in the northern Australia beef industry

Patricia Menchon 0000-0001-9312-6507, Jaime K. Manning 0000-0003-4785-4313, Dave L. Swain and Amy Cosby 0000-0003-2199-7607
 

Genetic improvement of beef production systems is a development priority for the northern Australia beef industry, which could be achieved through the adoption of genetic tools. Technical understanding, on-farm data collection, age of farmers, and the economic and productive benefits observed in beef enterprises are factors that affect decision-making by farmers regarding the adoption of genetic tools. This knowledge will allow the development of extension strategies to improve adoption of genetic tools by northern Australian beef producers.

Nitrogen excretion in feces and urine of beef cattle is a potential environmental contaminant. This impact is minimized by adjusting dietary protein levels according to nutritional requirements. However, measuring nitrogen excretion on farms is unfeasible. Therefore, nitrogen excretion prediction equations will be useful to understand the environmental impact of production systems.

AN25089Production of Rhode Island Red × Naked Neck hybrid hens under conditions of the family poultry production systems in a warm environment

Adrián Hernández 0000-0002-2780-4362, Gerardo Ordaz 0000-0003-4502-3727, Ernestina Gutiérrez 0009-0003-8983-2689, Aureliano Juárez 0000-0003-2372-1209 and Ruy Ortiz
 

Naked Neck hens offer key advantages for family poultry farming, especially in warm climates. Their higher heat tolerance helps maintain stable feed intake and consistent egg production, unlike fully feathered breeds. They also exhibit better feed conversion efficiency, lowering feeding costs and improving resource use. With reduced metabolic heat production, they achieve better thermal balance, supporting growth and reproduction. These traits make them a sustainable and profitable choice for small-scale poultry systems facing challenging environmental conditions.

AN25087Optimizing drinking water temperature for water buffaloes (Bubalus bubalis) during winter: implications for productivity under subtropical climate

Neelam Purohit, Indu Devi 0000-0001-8346-9020, Divyanshu Singh Tomar and Kuldeep Dudi
 

During winters in subtropical climates, the temperature of drinking water in troughs falls below 10°C. Increasing drinking water temperature to 20–24°C improves buffalo productivity by increasing milk yield and feed intake during winter. Warm water helps buffaloes maintain body temperature, reduce respiration rate, and alleviate cold stress, ensuring better physiological stability. Improved hydration and nutrient absorption contribute to better overall health and efficiency in dairy buffalo management. The study identified a cost-effective strategy for dairy farmers; heating water beyond 20–24°C provides no additional benefits.

A. M. Raseona 0000-0002-5517-7976, O. D. Owiny, T. L. Nedambale and D. M. Barry
 

The unexpected losses of genetically valuable animals have led to possibilities to preserve their genetic material. This study aimed to evaluate viability of spermatozoa retrieved from the epididymides refrigerated for 24 h at 5°C, diluted with Triladyl® or modified Ham’s F10, and preserved for 120 h at 5°C. The results revealed that cooling of epididymides before the recovery of sperm cells was efficient in preserving epididymal sperm viability.

This study evaluated the impact of corn ethanol byproducts on feed intake, digestion, and growth performance in young Nellore bulls. Replacing conventional ingredients with 30% dry distillers grains plus solubles (DDGS) promoted a 27% increase in dietary protein, promoting a higher weight gain and feed efficiency than control diets. Corn ethanol byproducts can replace conventional protein and energy sources. The inclusion of corn ethanol byproducts promoted an increase in overall performance, making them a sustainable feed option for beef production.
