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.

Key words: Swine, Heredity of quantitative characters, Fattening and carcass characters
