Abstract: In the present study,the correlation between shank length,shank girth and body weight of 120-day-old Guixiang Chicken was assessed using three batches of Guixiang Chicken.The results showed that the third batch of Guixiang Chicken had significant higher body weight and shank girth at the age of 120 days than that of the first batch(P〈0.05),and the second and third batches had significant higher shank length at the age of 120 days than that of the first batch(P〈0.05).The correlation analysis showed that the first batch displayed very significant correlation between the body weight and shank length as well as shank girth at the age of 120 days(P〈0.01),and the correlation coefficients were 0.583 and 0.623,respectively;there was very significant correlation between the shank length and shank girth at the age of 120 days in the first batch(P 0.01),and the correlation coefficients was 0.369.The analysis results based on the combined data of the second and third batches showed that the very significant correlation between the body weight and shank length as well as shank girth at the age of 120 days was observed(P〈0.01),and the correlation coefficients were 0.605 and 0.726,respectively;the very significant correlation between the shank length and shank girth at the age of 120 days was also observed(P〈0.01),and the correlation coefficients was 0.463.These results lay a theoretical foundation for the selection of body weight,shank length and shank girth traits in Guixiang Chicken,especially for the combined selection of the three traits.
