獭兔早期生长曲线的拟合与分析
Fitting and Analysis on the Rex Rabbit Early Growth Curve
摘要
Abstract
In order to fit the growth curve of rex rabbit,3 non-linear models(Gompertz,Logistic and Von Bertalanffy)were used to fit the growth of selected Beaver×Beaver rex rabbit(Beaver×Beaver as follows)and White×White rex rabbit(White×White as follows)from 1~5 month. The results showed that:3 growth curve models could all well-fit the growth of rex rabbit(R2>0.99).The Gompertz and Bertalanffy models had the best effects on fitting with the growth curve of both Beaver×Beaver group(R2=0.996) and White×White group(R2=0.997),respectively. The turning points of month age in Beaver×Beaver group were 1.88 and 1.60,the turning points of weight were 1 282.8 g and 1 107.8 g;while in White×White group,the turning points of month age were 2.29 and 2.08,the turning points of weight were 1 392.6 g and 1 264.35 g.The mean weight of different months in Beaver×Beaver group was significantly higher than that in White×White group. From the average daily gain curve,the growth peaks of Beaver× Beaver and White×White both appeared at 60~90 days,which was basically the same with the growth model.Later the average daily gain decreased,and the curve became smooth. This indicated that the growth speed of rex rabbit decreased along with the increase of month age. This study provids experimental evidences for rex rabbit breeding and early selection.关键词
