Promoting quality: an interactive exercise

Four recommendations to prevent cannibalism, its resulting increase in mortality and loss of productivity. Egg Industry and its readers investigated how to prevent cannibalism in brown-feathered laying flocks housed in broiler breeder units with slatsand litter. 1. Four recommendations for prevention: Rearing flocks must be given the opportunity to perch using either A-frames or suspended tubular perches. 2. Rocks must be "walked" at least three times per day during rearing so they become accustomto workers. The program of stimulation should continue after transfer at approximately 17 weeks through peak production. In general the problems of aggression and vent peck are more severe in houses fitted with mechanical nests compared to manual collection due to less human contact associated with egg collection.
