Performance Comparative Analysis of Gaoligongshan Pig and Mingguang Small-ear Pig

The experiment analysed that the body weight,body ruler,slaughter performance and meat chemical composition between Gaoligongshan pig and Mingguang small-ear pig.Gaoligongshan pig were higher than Mingguang small-ear pig in body weight,body length and chest circumference;Gaoligongshan pig above Mingguang small-ear pig in carcass weight,dressing percentage,fat percentage,eye muscle area and back-fat thickness;the same between Gaoligongshan pig and Mingguang small-ear pig in meat chemical composition.The results showed that the muscle chemical composition was approximate in Gaoligongshan pig and Mingguang small-ear pig,but the boby of Gaoligongshan pig was bigger,and the slaughtering performance was better than Mingguang small-ear pig.
