Infrared beak trimming protocols as an alternative to hot blade in commercial laying hens
This study aimed to compare hot blade with infrared beak trimming with different protocols on performance, beak length, digestive system organ biometry, intestinal histomorphometry, and egg quality in white laying hens. One hundred and twenty chicks were distributed in a completely randomized design in three beak trimming methods/protocols with five repetitions. Hot blade (HB) trimming was carried out at day 7, and infrared beak trimming was carried out at day 1, using light (LIR: 26/23 protection plate and 38 [...]
