【摘要】 <正> In this study, two breeds, Large White and Zhongxu black pig, 4 immune traits, and 4 production traits were measured for each individual, including whole IgG titer, specific IgG after vaccination to HCV (Hog Cholera Virus), the functional activity of mononuclear cell (FAMC), phagocytic capacity of polymorphonuclear leukocytes (PA), birth weight (BW), weaning weight (WW), backfat thickness (BFT) and loin eye area (LEA) at 140 days. The results showed that the means of each immune trait obtained from Zhongxu black pig were higher than those of the corresponding traits from the Large White, but the means of each production trait obtained from Large White were better than those of the corresponding traits from the Zhongxu black pig. Analysis of the factor possibly contributing to the difference of all traits indicated that the factor was the association between the breeds. The heritability (h2) of all measured traits and the genetic correlations between each trait were given, and the representative of the chosen immune traits as the status of body immunity was discussed, at the same tune, the hypothesis of the variation in ability to respond immunologically correlating with disease resistance ability was given.更多还原
