Abstract

The aim of this study was to evaluate the supplementation of chicken claw-derived bioactive peptides on performance, carcass weight, total intestinal bacteria, and feed dry matter (DMD) and organic matter (OMD) digestibility of broilers. A completely randomized design and five repetitions were applied in this experiment. The research material consisted of 200 DOC strain CP-707 grown up to 35 days of age, and the biopeptide was produced by hydrolyzing chicken claws protein with a commercial papain enzyme. Bioactive peptides were added to feed treatments in amounts of 0, 2, 4, and 6. The differences between treatments were tested using the honestly significant difference test. The addition of chicken claws biopeptides had a significant influence (P<0.01) on OMD and carcass weight, as well as a significant effect (P<0.05) on body weight gain, feed efficiency, DMD and total bacteria. Addition of chicken claws-derived peptides in rations up to 6 enhanced body weight gain, feed efficiency, carcass weight, DMD, OMD, and total intestinal bacteria in broiler chickens. © (2023), (Scienceline Publication).
