Beak trimming using infrared, hot blade straight cut, and hot blade V-cut on laying hen production
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 [...]
