Abstract: Chickens including 30 Wenshang luhua chickens,30 Jining bairi chickens and 30 Laiwu black chickens were used for comparative analysis on carcass performance at the age of 170 d. The results showed that live body weight of the Jining bairi chickens was highest, reaching 1532.03 g, Laiwu black chickens was 1431.20 g and Wenshang luhua chicken was 1369.83 g (P<0.01).the Laiwu black chickens had the highest carcass percentage, percentage of half-eviscerated weight, percentage of eviscerated weight, and percentage of quarter, and significantly (P<0.05) or very significantly (P<0.01).From 15 min to 24 h post slaughter, the pH values of muscles displayed a declining trend, and these values were within the pH range of the normal muscles. The content of intramuscular fat of the Jining bairi chickens was the highest, the shear force of leg muscle and the content of intramuscular fat was the lowest in Jining bairi chickens. all varieties of body feature close to,the Wenshang luhua chickens had the smallest hip bone width and shank circumference, the biggest was Laiwu black chickens.

Key words: local chickens; carcass traits; body size traits
