The modern broiler and breeder are performing at levels never seen before. In order to multiply by 15x (or more) their bodyweight in just four weeks, they do not have the time to correct the effects of nutritional deficiencies. In a recently published paper coming from the University of Alberta, the effect of genetic selection was studied using unselected strains from 1957, 1978 and a 2005 commercial Ross 308 strain and fed contemporary modern diets. Some of the results included an increase in broiler growth by 400% and a feed conversion ratio reduction of 50% when comparing 1957 to 2005. On top of this, breast meat yield increased by 79% in males and 85% in females. The genetic of the chick has changed so dramatically, it can be compared to a high performance athlete. The correct amount of nutrients should be present in their blood from the very beginning and of course everything starts from the egg. The day old chick depends 100% on the egg nutrient composition to develop all their organs and functions, activate all their necessary genes and systems and become fully ready to start growing right from the very beginning. Therefore, it is important to review the aspects of breeder nutrition that will provide the chick with the best start. It is the objective of this article to review some of the main factors of breeder nutrition affecting chick performance.
