Evaluation of production performance of five commercial broiler chickens

This study was conducted to evaluate the growth performance and carcass characteristics of five commercial broiler chickens(Arborakers,Aryan,Ross308, Cubb and Hubbard)available in Iran. First of all, the fertile eggs were hatched from broiler breeder with 31-33 weeks age at the same time. Two hundred sixty one day old broiler chickens were allocated to a completely randomized design with 5 treatments (broiler strains),4 replicates and 13 birds in each replicate. The peirod of experiment was 42 days. The results of this experiment indicated that,treatements had effect significant on the amount of feed intake,the heighest and lowest feed intake related to Hubard(77.1g/d), Ross (83.38g/d) and Arborakers (84.15g/d) respectively(P0.05).In general,the results of this experiment showed weight gain, feed conversion and and carcass quality were not significantly different between broiler strains,therefore each of these could be raised in condition of management and feeding similar to this experiment.
