The objective of this study was to investigate the effect of exogenous protease supplementation in dietsformulated with poultry by-product meal on growth performance, small intestine magnitudes, and meat physiochemicalcharacters in broiler chickens from 21 to 35 days post-hatch. A total of 120, one-day-old "Arbor Acres Plus" broiler chickens(male: female - 50:50) were allocated one of two dietary treatments to give six replicates and ten birds per cage. Two dietarytreatments included a control diet (CON) and a diet supplemented with protease (CON+Pro). At day 35, body weight andfeed intakes were measured to calculate the feed conversion ratio for the entire experiment period. Two birds from each penwere euthanized to measure the relative lengths and relative weights of three small intestine sections and meat samples werecollected for physiochemical characteristic analyses at 35 days post-hatch. Exogenous protease supplementation did notinfluence (P>0.05) growth performance but showed a tendency to improve FCR (P=0.082). Protease supplementation showed a tendency to reduce proximal small intestine length (P=0.091). Broilers offered dietary treatments influenced minced meatcolor where protease supplementation resulted in lower CIE b* (P<0.001) colorimetric value for yellowness and showed a significant trend (P=0.059) on reducing meat redness CIE a*. In conclusion, the addition of exogenous protease to a broilerdiet formulated with poultry by-product meal did not affect the growth performance, small intestine magnitudes, and meatphysiochemical parameters (except CIE b*) in broiler chickens.
