In this episode of The Poultry Nutrition Blackbelt Podcast, Dr. Oluyinka Olukosi from the University of Georgia shares key findings from his studies with reduced-protein diets in poultry diets. He explains the role of alternative protein sources, amino acid supplementation, and phase-specific feeding strategies in maintaining performance. Learn how these approaches impact both production and environmental outcomes. Listen now on all major platforms!

"Digestible amino acid formulation has allowed progressive crude protein reduction over time in poultry diets."

Meet the guest: Dr. Oluyinka Olukosi earned his Ph.D. in Animal Sciences from Purdue University after completing his degree at Obafemi Awolowo University in Nigeria. Now an Associate Professor at the University of Georgia, he researches ways to reduce nutrient excretion through strategic protein, amino acid, and enzyme use in poultry nutrition.

Assessment of two diet types in reduced-crude protein diets with or without phytase supplementation – implications on key phenotypic responses in 21-day-old broiler chickens

Growth performance and immune response of broilers during active Eimeria infection are modified by dietary inclusion of canola meal or corn-DDGS in reduced-protein corn-soybean meal diets

Phase-specific outcomes of arginine or branched-chain amino acids supplementation in low crude protein diets on performance, nutrient digestibility, and expression of tissue protein synthesis and degradation in broiler chickens infected with mixed Eimeria spp.

Growth, not digestibility, in chickens receiving reduced-protein diets is independent of non-specific amino-nitrogen sources when the essential-to-total-nitrogen ratio is constant and lower than 50%

In this episode of The Poultry Nutrition Blackbelt Podcast, Dr. Cangliang Shen from West Virginia University explores how microbial contamination in poultry poses emerging challenges for food safety. He discusses the use of surrogate bacteria, thermal processing techniques, and sanitation protocols in real-world poultry feed operations. Listen now on all major platforms!

"We find that temperature up to 80°C can reach a three log reduction for the efficiency, which gives us hints for developing sanitation procedures and hazard plans for local industry facilities."

Meet the guest: Dr. Cangliang Shen earned his Ph.D. in Meat Science and Food Safety from Colorado State University, with earlier training in Veterinary Medicine. He is currently a Professor and Extension Specialist at West Virginia University, focusing on improving poultry meat and feed safety through microbiological research and hazard planning.
