Effects of different infrared beak treatment protocols on chicken welfare and physiology

open access: yesPoultry Science, 2012
Infrared beak trimming provides an alternative to conventional trimming, purporting to provide a welfare-friendly means of trimming. The infrared system can be adjusted to use multiple plate and power settings. In the present study, we used 2 different plate sizes (27/23C, less severe; 25/23C, more severe) with each of 3 power settings: high (52 ...
