Abstract
In order to understand the growth characteristics of Qingyuan yellow-feathered black bone chicken and select the best growth curve model,a total of 100 healthy Qingyuan yellow-feathered black bone chicken in the same batch number(half male and female)were selected in the experiment to measure the body weight weekly.Three models of Logistic,Von Bertalanffy and Gompertz were used to fit and analyze the body weight data of 0-22 week-old Qingyuan yellow-feathered black bone chicken.The results showed that the fitting degree(R2)of the three growth curve models were more than 0.990,which could be used to describe the growth and development laws of Qingyuan yellow-feathered black bone chicken.Among them,the fitting degree(R2)of the body weight of cocks by Gompertz model was the highest,being 0.999.The results showed that the inflection point body weight of cocks was 950.49 g,the week-age of inflection point was 10.28 w,and the maximum weekly weight gain was 133.07 g.The fitting degree of the body weight of hens by Von Bertalanffy model was the highest(0.999).The results showed that the inflection point body weight of the hens was 757.62 g,the inflection point week-age was 10.47 w,and the maximum weekly weight gain was 90.91 g.The above results showed that the Gompertz model was more suitable for fitting the growth process of the cocks,and the Von Bertalanffy model was more suitable for fitting the growth process of the hens.The results preliminarily revealed the growth process of Qingyuan yellow-feathered black bone chicken,and provided references for breeding,feeding management and practical production of this breed.关键词
