Hetian chickens were selected as the research material,and body size and slaughter performance were determined at 150 days of age(market age)and 300 days of age,respectively.The results showed as follows:the body weight,oblique length,keel length,chest depth,chest width and shin circumference of adult Hetian cocks(300 days of age)were significantly higher than those of market age cocks(P<0.05,P<0.01).The body weight,body oblique length,breast depth,breast width and shin length of adult Hetian hens(300 days of age)were significantly higher than those of market age hens(P<0.05,P<0.01).The slaughter rate of 300-day-old Hetian cocks was significantly higher than that of 150-day-old(P<0.01),and the leg muscle rate of 150-day-old Hetian hens was significantly lower than that of 300-day-old Hetian hens,but there was no significant difference in other slaughtering performance(P>0.05).This provides a theoretical basis for breeding preservation and further development and utilization of hetain fowl.
