| 摘 要： | 以舍饲型合作猪为研究对象,对其生长发育进行了研究,并运用Gompertz、Richards和Logistic三种非线性模型拟合了体重变化规律。结果表明：舍饲型合作猪体重与占初生重倍数随日龄增加而逐渐增大,相对生长率随日龄增加逐渐下降,90-120日龄日增重最大,为242.5 g;Gompertz模型拟合效果最理想（R^2=0.9995）,用此模型拟合成年公猪体重为47.02 kg,成年母猪体重为59.86 kg;公、母猪生长拐点分别在118.32 d和146.75 d。

| Abstract: | Growth and development law has been studied about Hezuo Pig regarded as the research object in shelter feeding.Three unlinear model of Logistic,Richards and Gompertz were used to fit discipline of body weitht.The results indicated that body weight and ratio of born weight increased with age gradually,but relative growth rate decreased with age.Daily weight gain which was 242.5g per day was maximum from 90 day to 120 day of age.Fitting effect of Gompertz was ideal among three kinds of model(R2=0.9995).The ad... |
