Effects of beak trimming on the performance, beak length, behavior, and carcass traits of a local broiler breed reared in battery cages

Abstract

This study investigated the effects of beak trimming on a local broiler breed. A total of 648 one-day-old birds were randomly allocated into three treatments: no trimming (NBT), infrared beak trimming (IRBT), and hot-blade beak trimming (HBBT). The performance, beak length, behavior, carcass traits, organ percentages, and meat quality were inspected. The body weight (BW) from 7 to 35 days in the IRBT group was significantly lower than that in the NBT group, and the BW from 7 to 49 days was lower than that in the HBBT group (p
