The nutritional requirements of broiler breeders and the effect of feed makeup on their performance has been the subject of considerable research. The present paper reviews the literature available on the subject, examining the effects on parameters such as egg production, egg weight, egg composition, fertility and hatchability, offspring performance, and body weight. The importance of amino acid intake (especially of lysine and methionine) and its relationship with dietary protein is discussed. Special emphasis is given to literature dealing with the effects of diet protein on fertility and hatchability and of the effects of egg weight on offspring performance. The impact of body weight on broiler breeder performance is described.

Key Words: Amino acids • body weight • broiler breeders • egg composition • egg production • egg weight • offspring performance • protein
