Title

Evaluation the effect of diets formulated according to the Arian and Ross strains catalogue on performance and carcass characteristics of broilers

Abstract

 This study was conducted to evaluate the effect of diets formulated based on Arian and Ross broilers catalogues on performance and carcass characteristics of these two strtains. In this study, a total of 640 one-day old Arian and Ross broilers were used in a 2 2 2 factorial trial (two strains two sexes two diets) in a completely randomized design, with 4 replications and 20 chicks in each replication. The results showed that at the entire experimental period (49 day of age), body weight gain (BWG) and European Efficiency Factor (EEF) of Ross chicks were significantly (P<0. 05) higher and their feed conversion ratio was significantly (P<0. 01) better than those of Arian chicks. Feed consumption, BWG and EEF of Arian and Ross chicks fed diets formulated based on Arian catalogue were significantly (P<0. 01) higher than those fed diets formulated according to Ross catalogue. Carcass and breast meat percentages of Ross chickens were significantly (P<0. 05) higher and their abdominal fat and viscera percentages were significantly (P<0. 01) lower than Arian chickens. Energy and protein consumption per kg total BWG and carcass yield and also the total feed cost per kg BWG and carcass yield of Ross chicks were significantly (P<0. 05) lower than Arian chicks. However, the feed plus chick cost did not have any significant difference. It seems that Ross broilers have better productive characteristics, compared to Arian broilers, but formulation of the diets based on the Arian catalogue (longer utilization of starter and grower diets) would improve the performance of both Arian and Ross broilers.
