Lower-protein broiler diets with extra threonine
432 broilers were fed 90–100% of Ross protein recommendations with 100–120% threonine. After the starter period, protein could be cut by up to 10% without harming growth, and threonine up to 110% of Ross values helped make up for slower growth on low-protein diets.
Practical takeawayAfter the starter phase, a moderate protein cut plus threonine can lower feed cost without losing performance.
