Broiler breeders are the parent stock of broiler chickens and therefore responsible for millions of tons of poultry meat. Appropriate management in rearing and in the production period is essential to produce a high number of fertile eggs and high quality broiler chickens. There is a wide range of factors influencing broiler breeder production parameters, health and economics of a flock. A clear focus on the basic management factors (housing, breed, climate, biosecurity, etc.) can limit negative production responses in an early stage, improving overall profitability of the production chain. Besides previous mentioned factors, nutrition played a very important role on the reproduction performance of broiler breeders. An important topic in broiler breeder reproduction, besides number of eggs produced, is fertility and hatchability of eggs. Old and recent research suggest that a lower protein level, especially in the second part of the laying period, improved the fertility of hatching eggs. It is clear that crude protein (and AA) levels must be optimized in the different phases of the productive life of the breeders. A low dietary CP diet (supplemented with free AA) will not affect egg and chick production during phases 1 and 2, however, egg and chick production can be reduced when birds are fed a (too) low dietary CP diets during phase 3. Separated sex feeding in combination with a specific male diet is recommended to maximize number of fertile eggs.
