Dose-dependent effect of a protease complex in low-protein diets with feather meal on broiler productivity and digestive physiology
Submitted by Гость (not verified) on Thu, 10/01/2026 - 17:08The aim of the study was to comprehensively assess the effect of different increased doses (4 to 7 times the recommended level) of an exogenous protease complex (0, 500, and 1000 g/t) in low-protein diets containing 6% feather meal on productivity and proteolytic activity in the gastrointestinal tract of broilers. The experiment was carried out on 400 day-old Ross 308 broilers (44 days of age).
