Phytase and nutrient-energy matrix: a strategic approach to enhancing the performance of broiler chickens fed a corn-soybean meal-based diet.

Objective: This study examined the effects of a nutrient matrix with or without phytase on the performance of broiler chicken.

Methods: A total of 2000 day-old Ross 308 broiler chickens were assigned to 5 dietary treatments, with 10 broilers per replicate and 40 replicates per treatment. The experimental diets included 1.
