Evaluation of the effects of different levels of sulfur containing Amino acid content of diet on young and adult breeders performance

This Study was conducted to evaluate the effects of different levels of Sulfur containing amino acids (80 to 120 Percent of requierments) content of diet on young breeders growth and adult breeders performance in three stages. Management and diets were as descrined by Arian company. The experimental diets were isoealoric but contained various levels of Methionine. The experimental design was completely randomized design (CRD). The results of this experiment indicate that young breeders growth was not significantly affected due to sulfur amino acids levels (P>0.05). Also EP (%), EM (grʹhen/day), hatchability (%) and day old off spring body weight (g) were not influenced by sulfur amino acid levels (P<0.05). Under the condition of this experiment, diet containing 80 percent of sulfur containing amino acids requierments with 17 percent of crude protein seems to be enough to support an acceptable performance for both young and adult Arian broiler breeders.
