Abstract
The objectives of this research was to evaluate the effect of biopeptide supplementation from chicken claw on carcass weight, total intestinal bacteria and digestibility of dry matter (DDM) and organic matter (DOM) of broilers. Experimental research using completely randomized design and five times repetition. The research material were 200 DOC strain CP-707 that were reared up to 35 days of age and the bio-peptides was obtained through hydrolysis of chicken claw collagen using a commercial papain enzyme. Feed treatments were supplemented by bio-peptides in the amount of 0, 2, 4, and 6%. The polynomial orthogonal was applied if the treatments have a significantly effect on the measured variables. Supplementation of bio-peptides from chicken feet had a very significantly effect (P<0.01) on DOM and carcass weight and had significantly effect (P<0.05) on DDM and total bacterias. Bio-peptides supplementation up to the level of 6% in broiler ration improved carcass weight, DDM, DOM and total intestinal bacteria of broiler chickens.
