In this episode of The Dairy Podcast Show, Alex Benoit, PhD student at Cornell University, discusses research evaluating the interactions between amino acids and fatty acids on milk production and milk composition in lactating dairy cows. She explains current knowledge on how these nutrients influence milk fat, milk protein, and energetic efficiency, and why balancing them matters for modern dairy systems. Alex also shares why this research is critical for supporting future nutrition strategies and outlines the next steps in her research program. Listen now on all major platforms!

"The mammary gland is full of protein, and one of the hypotheses is that amino acids may support synthetic activity, enzyme structures, signaling mechanisms that direct nutrients, or act as an energy source through oxidation."

Meet the guest: Alex Benoit is a PhD student in Animal Sciences at Cornell University, with an MS from Michigan State University and a strong background in dairy cattle nutrition research. Her work focuses on interactions between amino acids and fatty acids and their role in milk fat and protein synthesis.
