OverviewAI-generated summary
Weasley A Orlando researches livestock production, focusing on swine nutrition and reproductive performance. His work investigates the impact of various feeding strategies and nutrient levels on growth, mortality, and reproductive outcomes in pigs. Specific studies examine the effects of standardized ileal digestible lysine and tryptophan to lysine ratios on grow-finish pig performance and behavior, as well as the requirements for lysine and phosphorus in different feeding scenarios. Orlando also studies factors influencing sow reproductive success, including body weight changes during gestation and lactation, and the effects of different lactation feeding management practices on gilts and sows. His research contributes to optimizing animal husbandry practices through evidence-based nutritional and management recommendations.
