Evaluation of the diets formulation type on performance of Arian broiler breeder hens
AbstractA study was conducted to determine the effects of diet formulation type on broiler breeder performance of 50 to 64 weeks of age. Three hundred and thirty six (336) female and 48 male breeders in eight treatments with six replicates (seven females with a male) were used in the form of a randomized trial design 2×2×2 factorial. Eight experimental diets were formulated based on three factors: first factor included two levels of apparent and true metabolizable energy corrected for nitrogen (AMEn and TMEn) of feed, the second factor included two levels of total amino acids (TAAF) and digestible (DAAF) of feed and the third factor included two levels of broiler breeder hens requirements based on total amino acids (TAAR) and digestible (DAAR). The results show that egg weight was significantly different which was affected by diets formulation based on energy (P<0.05). Diet formulation based on amino acids of feed and requirements had no effect on egg weight (P>0.05). Treatment 3 (AMEn+DAAF+TAAR) was at the best level significantly different in egg weight 68.97 (g), egg production 62.45%, egg mass 43.1 (g/hen/day) and feed conversion ratio 3.59 (P<0.05). Hatching eggs and hatchability was significantly different, which was affected by diet formulation based on energy, amino acids of feed and requirements (P<0.05). This experiment shows that the type of formulation of diets had significant effects on broiler breeder performance.
