摘　　要：为了给凉山猪保种及开发利用提供一些基础数据,本试验选取乐山市马边县民主乡的68头凉山猪作为代表,进行了凉山猪体尺与活体重间的线性回归分析。结果表明:凉山黑猪的体型较小,平均体重为86.5kg;在凉山猪处于放牧饲养状态时,可采用测量凉山猪胸围的方式估计其体重,通过公式估测的体重拟合值精度较高。In order to provide some native swine, linear regression analysis basic data for the conservation and involving body size and live weight experiment, 68 Liangshan native swines as trial pigs came from Mabian county. that Liangshan native swine had relative small body size, its average weight was swine was grazed high accuracy of exploitation of Liangshan was conducted in this The basic data indicated 86.5 kg; when the native openly outside, its weight could be estimated by measuring its bust size. A relatively fitted values was obtained when the formula was put into use.
