ABSTRACT This study investigated the effects of different beak trimming methods on the development, hematological parameters, cloacal temperature, beak length, egg quality, and laying performance of laying hens from 1 to 31 weeks of age. Nine hundred Lohmann White LSL-Lite laying hens were randomly assigned to three treatments based on beak trimming methods: infrared radiation, hot blade straight cut, and hot blade V-cut. Laying hens subjected to the hot blade V-cut method had lower feed intake, body weight gain, laying […]
