Optimizing low-protein diets in broiler chickens: The role of grain type and dietary arginine to lysine ratio

Chicken-meat is one of the most accessible, affordable and accepted animal protein worldwide, presenting a promising solution to food security while maintaining minimal greenhouse gas emissions and low carbon footprints. Broiler chicken diets typically comprise 20 to 23% protein, with soybean meal being the primary protein source. Advancements have been made in the form of low-protein broiler diets, which reduce soybean meal usage by substituting with crystalline amino acids.
