Recorded live from IPPE, this episode features Charis Waters, PhD student at Mississippi State University, and Dr. Pratima Adhikari of Mississippi State University as they explore emerging research on branched-chain amino acids (BCAAs) in laying hens. Their discussion examines how advances in precision amino acid nutrition are helping producers better support the performance, health, and productivity of today’s genetically improved laying birds. Moreover, they discuss how these advances are shaping the future of poultry nutrition.
Episode 20: Student Showcase: Mississippi State
🎧 Episode Overview
The poultry industry continues to evolve as genetics, production goals, and feed formulations advance. In this episode of the Real Science Exchange, we welcome Dr. Pratima Adhikari and Charis Waters from Mississippi State University. They discuss emerging research on branched-chain amino acids (BCAA) and their impact on modern layer nutrition.
Throughout the conversation, the group explores how balancing leucine, isoleucine, and valine can influence laying hen performance, feed efficiency, egg quality, and long-term productivity. The discussion also highlights why poultry nutritionists may need to move beyond outdated nutritional recommendations. Specifically, this is important to support today’s high-performing layer genetics.
The episode opens with introductions and background on Mississippi State’s poultry nutrition program, including Dr. Adakari’s research focus and Charis Waters’ work on layer nutrition and amino acid optimization. (00:00 – 05:15)
The discussion then shifts into Charis’s research on branched-chain amino acids—leucine, isoleucine, and valine—and their role in laying hen performance, particularly across pullet, peak, and late production phases. (05:15 – 07:05)
A key theme of the episode is the importance of amino acid ratios rather than absolute requirements. Elevated leucine levels in corn-based diets may create imbalances that affect production, feed intake, and efficiency if not properly adjusted. (06:57 – 10:01)
The conversation also highlights how this research reflects broader changes in the industry, including the impact of modern genetics and the limitations of outdated NRC (1994) recommendations. In addition, the need for updated nutritional models is emphasized. The panel further explores how BCAA nutrition influences not just performance, but egg quality, bone strength, and laying longevity. Thus, the importance of balancing diets for both productivity and animal welfare is reinforced. (12:03 – 19:55)
The discussion also touches on egg composition and amino acid profiles, including how dietary changes may influence crude protein levels, albumen quality, and overall egg integrity. Furthermore, attention is given to broader applications of this research, including potential implications for breeder flocks, feather quality, and stress indicators. This suggests that BCAA balance may have system-wide biological effects (20:45 – 23:53)
The episode concludes with practical insights for producers and nutritionists, emphasizing that fine-tuning amino acid ratios offers a cost-effective way to improve performance without drastic diet changes. As a result, this aligns economic and biological outcomes.
