摘要
采用Logistic生长曲线原理对獭兔生长期生长曲线进行拟合,建立獭兔生长曲线方程,探索獭兔的生长规律。结果表明:①根据Logistic生长曲线方程原理,确定了獭兔生长曲线方程参数a=24.1504,b=1.2402,并对方程进行了拟合,建立了獭兔生长曲线方程=2949/(1+24.1504e-1.2402x)(P<0.05);②Logistic方程能很好地拟合獭兔的生长过程,拟合度均在0.95以上,生长的拐点时间为2.97月龄,拐点体重为2298.28g,极限体重参数2949g。
Measured Rex Rabbit＇s weight in Heibei Xing Sheng Culture Company,fitted the equation according to the principle in the equation of Logistic curve of growth, established the equation of Rex Rabbit ＇ s curve of growth, then study the Growth Law of Rex Rabbit. The growth curves of Rex Rabbit from 0 to 5 months old were analyzed and fitted with Logistic model. The results showed as follows： ①According to the principle in the equation of logistic curve of growth, we identified the equation＇s parameter of growth curve y： a=24.150 4, b=1.240 2, then fitted the equation, established the equation of Rex rabbit＇s curve of growth： y =2 949/（1 ＋24.150 4e-1.240 2x）（P〈0.05）. ②Logistic regression curve equation can be very good fit Rex Rabbit growth process. inflection point of growth weight of Rex rabbit was The fitting degree of Logistic regression curve equation was more than 0.95. Its was 2.97 months. The inflection point of Rex rabbit weight was 2 298.28g. Extreme 2 949g
