摘要
通过运用Logistic、Compertz和Bertalanffy模型拟合优质广西三黄鸡生长期体重、胫长和胫宽的生长曲线,发现3种模型都能很好地拟合体重、胫长和胫宽的生长曲线,与体重相比,胫长和胫宽属于早期发育性状,16周龄胫长与胫宽已经非常接近极限值,但体重仍有较大的增长空间。
Growth curve of body weight,shank length and shank width of Guangxi yellow chicken were fitted by model of Logistic,Compertz and Bertalanffy. We found that growth curve of body weight,shank length and shank width could be fitted well by these models. Compared to body weight,shank length and shank width were early-growth characters. In the sixteenth week,shank length and shank width of Guangxi yellow chicken had closed to their limits while body weight still had comparatively large growth.
