摘要
为了初步拟合分析贵州小型猪的早期生长曲线,试验测定了贵州小型猪初生、1～6月龄体重,用SPSS17.0统计软件进行生长曲线拟合分析。结果表明:幼龄贵州小型猪生长曲线拟合以三次多项式模型、二次多项式模型、线性模型拟合度较好,相关系数分别为0.999,0.995,0.955。说明初生至6月龄的贵州小型猪正处于快速生长阶段。
：To preliminarily fit and analyze the early growth curve of Guizhou miniature pig, the body weights of the Guizhou miniature pigs were measured from 0 to 6 months of age, and used to construct the growth curve, and then the SPSS17.0 statistics software was used to fit and ana- lyze the growth curve. The results showed that cubic polynomial model, the quadratic polynomial model and the linear model had better fitting effects on the growth curve fitting for young Guizhou miniature pigs, and their correlation coefficients were 0. 999, 0. 995, and 0. 955, respec- tively. It indicates that the Guizhou miniature pigs from 0 to 6 months of age are in a rapid growth stage.
