Technical Abstract: The most recent information on broiler breeder nutrition is presented in these symposium proceedings. Previous studies have suggested that increased protein intake during prebreeder period improves reproductive performance. A study was conducted to determine the effect of dietary crude protein on performance. The results showed that while excess protein does not appear to be beneficial, it was shown that lower than recommended protein intake has a detrimental effect on performance. Controlling broiler breeder body weight is essential to achieving optimal production of hatching eggs. To avoid excessive body weight feed restriction programs have been implemented, however, this leads to the development of an overactive lipogenic system. The results of this trial showed that everyday fed breeders produced more eggs that restrict-fed breeders, and that carnitine supplementation has a beneficial effect on egg production and size.
