试验研究黄郎鸡的体重增长规律及体重和体尺性状间的关联.试验选取170只同批次健康状况良好的1日龄黄郎鸡(公:80只,母:90只),测定并记录0～23周龄的体重、13周龄的体尺,采用Logistic、Gompertz以及Von Bertalanffy 三种非线性数学模型对0～23周龄不同性别的黄郎鸡体重数据进行拟合分析,同时对13周龄黄郎鸡公母之间的体尺性状进行比较,并分析体重与体尺之间的相关性.结果表明:拟合黄郎鸡生长曲线效果最佳的模型是Gompertz模型,拟合度(公:R2=0.998,母:R2=0.998),拐点周龄(公:7.93周,母:8.43周),拐点体重(公:612.49 g,母:540.56 g),最大周增重(公:104.12 g,母:81.08 g).黄郎鸡公鸡的体重与体斜长、...

The study of the weight growth law and the association between weight and body size traits of Huanglang chicken provided theoretical support for the scientific breeding and early breeding of Huang-lang chicken.A total of 170 Huanglang chickens,including 80 males and 90 females,were selected in the same batch and in good health.The weight of 0 to 23 weeks old and the body size of 13 weeks old were measured and recorded,and the weight data of Huanglang chicken of different sexes aged 0 to 23 weeks was fitted and analyzed by Logistic,Gompertz and Von Bertalanffy,and the body size traits be-tween ...
