摘要

The influence of genotype on carcass quality of Celta pig breed was studied. A total of 16 Carballina line and 20 Barcina line pigs from the Celta breed were used. The average carcass weight, 149 and 138 kg for Carballina and Barcina line respectively, were higher than the average commercial pig slaughtered in Galicia and Spain. On the other hand, we observed significant differences (P<0.05) respect to chilling losses (1.84 vs. 2.21, for Carballina and Barcina line, respectively). With regard, the morphometric parameters, there were no statistically differences between genotypes except for the DFT1 (P<0.01) and DFT2 (P<0.05), since these parameters were always higher in carballina line. Genotype had statistically significant effect on the proportionality of some individual joints: head loin, ham, jowl, baicon and head. For the rest of joints, differences between sexes were small and not significant. The PCA offered a good separation of the mean samples according to the carcass quality. The PC1 axis was mainly characterized by slaughter weight, HCW, CCW, CL, LL, HmL, ham and shoulder. The variables that were positively aligned with PC2 were ETD2, ETD3, ETD4 and baicon, while killing out was positively aligned with PC3.
