Özet
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). The results of the correlation analysis revealed that only the first canonical correlation was significant for both ages (P = 0.035 and 0.0013). Correlations were higher for data recorded in the fourth week of age than in the second week of age. The estimated canonical correlations indicate that live body weight, shank length and breast width is clearly positively correlated with hot carcass weight, beck weight and right rump weight at both ages. Pre-slaughter traits recorded at two weeks of age are suitable to estimating post-slaughter traits.
