In this episode of The Poultry Nutrition Blackbelt Podcast, Charis Waters, a PhD student at Mississippi State University, shares her research on the effects of limestone particle size ratios and phytase levels inclusion on laying hens' performance and bone quality. With insights into phytase super-dosing and bone health, Charis explores how these factors can optimize egg production and hen welfare. Tune in now on all major platforms.

"Calcium source and batch consistency greatly influence bioavailability, impacting laying hens’ production and bone health."

Meet the guest: Charis Waters is a Graduate Research Assistant, PhD student in the Department of Poultry Science at Mississippi State University. She earned her Master’s in Poultry Science from Mississippi State, where she researched laying hen production, performance, bone health, and inositol levels in relation to limestone particle size ratios and phytase levels during the post-peak and late-lay periods. Her PhD research focuses on the role of branched-chain amino acids in laying hens, examining their growth from pullet to late-lay stages. Charis is also a member of the Poultry Science Association (PSA).
