Following simple feeding rules can lead to good results when managing broiler breeder males and achieve high hatchability.Breeding companies have their own views on feeding broiler breeder males and on the optimum mature weight guidelines to achieve high fertility throughout the life of the flock.Emphasis in breeding program selection continues to be placed on improved feed conversion. Yet farmers often find this challenging as the male response to feed intake may be different. They can become too heavy, with negative effects on hatchability andchick production. This, however, does not need to be the case.Focusing on the practical feeding of males during the production phase, with the adoption of a 'rule of thumb' method, can be successfully used to maintain top hatchability with large males.
