| Abstract: | Path analysis was conducted on the carcass traits that including carcass length,carcass weight, carcass yield,average backfat thickness,average skin thickness,ham weight and meat weight.The results showed that carcass weight and carcass yield have dromatically effect on meat weight. The optimum regression mode of carcass traits was established also.The equation of regression was: y=16.3668+0.1575x 2-17.6102x 3 |
