摘　　要：为比较巴玉、长玉二元杂交猪屠宰、肉质性能差异,本试验选取2窝日龄相同、体重接近的巴克夏×玉山黑猪、长白×玉山黑猪作为材料,在相同半放养饲养方式条件下进行饲喂试验,在试验猪只平均体质量达到135kg(平均350日龄)以上级别时按NY/T825-2004方法进行屠宰测定,结果显示:体长、皮厚、皮率、失水率、a﹡(红度)、脂肪含量两者之间差异极显著(P<0.01),眼肌面积、平均背膘厚度、脂率、两组之间差异显著(P<0.05);在硬脂酸、亚油酸、花生酸、花生四烯酸方面,长玉组含量高于巴玉组,其中硬脂酸前者高于后者14.75%,差异明显(P<0.05),但两者总体差异不明显(P>0.05)。To compare the difference between slaughter performance and meat traits of Bayu and Chan- gyu two-way cross breed, the experiment selected two nests of Barke Summer X Yushan Black pig, ChangbaiX Yushan Black pig of same ages and close weight as the material to raise under the same feeding mod- el. The tested pigs were slaughtered when the mean weight reached 13＇5 kg （350 dage）according to NY/ T825--2004 method. The results showed that there was extreme difference between two groups on body weight, bark thickness, papar rate, water loss rate, a and fat content （P〈0.01）, there was significant difference between two groups on eye muscle area, average back fat thickness and fat percentage （P〈0. 05）. The content of SA, Linoleic, Arachidic and ARA were higher than that of Bayu group, among which SA was 14.75% higher than that of the latter, with a significant difference （P〉0.05）, but the general difference of the two groups were insignificant （P〉0.05）.
