摘要： 对1988～1992年淮南猪育肥与胴体性状的表型和遗传参数的研究结果表明，淮南猪胴体重、胴体长、眼肌面积、后腿比例等的遗传力较高(0.629～0.723)；宰前活重和屠宰率的遗传力较低，分别为0.174和0.173，板油比例、花油比例及肥肉率的遗传力估计值分别为0.603、0.574和0.243。表型相关及遗传相关值与国内外资料有很多不同特点，反映了淮南猪边长边肥、体型短宽的品种特性。

Abstract: According to the fattening data of Huainan swine from 1987-1989,the phenotypic and genetic parameters of fattenin and carcass characters were calculated.The result showed that the heritability for carcass weight,carcass length,loinege area,and percentage of ham cut is fairly high (0.629-0.723),but heritability for the weight befor dressing and dressing percentage was rather low 0.174 and 0.178 respectively.The estimation of heritability for relative weights of mesentery fat, perirenal fat, and fat percentage is 0.547,0.603 and 0.243, respectively.This is the first report and has some significance to the study of quantilation heredity theories and practical selection.The estimates reflected the special characters of the short-wine-bodies Huainan swine which grow and fatten simultaneously.
