This study was done in order to investigate the relationships between pre-and post-slaughter traits of Ross 308 male chickens. For this aim, canonical correlation analysis was applied to data of 60 male Ross 308 broiler chickens. The analysis was designed to evaluate the relationships between two sets of variables (pre-and post-slaughter traits) of broilers. Pre-slaughter traits were recorded in the age of two and four weeks. Pre-slaughter traits: live weight, shank width, shank length, breast width, breast circumference and body length (X); post-slaughter traits: hot carcass weight, left rump weight, beck weight, breast weight and small right rump weight (Y).
