Abstract

A comparative study was conducted on data gathered from 45 farms located in different geographical regions of Iran (Guialn province vs. the others) in order to investigate factors affecting the economic performance of broiler chicks. Slaughter age (51.25 vs. 55.04 d), mortality (5.2 vs. 9.8 %) and FCR (1.9 vs. 2.1) in Guilan province were lower than the others (P<0.05). For initial (40.9 vs. 41.7 g) and final (2857 vs. 2752 g) body weights, the differences between two strains (Ross vs. Cobb) were not significant (P>0.05). Ross chicks showed better early growth and lower mortality (P<0.05) compared to the Cobb. Correlation between initial body weight and weight at the end of first week was positive and significant (c=0.44; P<0.05). A significant positive correlation (P<0.05) was found between feed intake and slaughter age (0.45), final body weight (0.44), FCR (0.53) and mortality (0.60). Results of this study showed superiority for Guilan province as a desirable location for rearing broiler chicks than the other investigated regions. Also, indicated that the two strains have different performance.
