猪白细胞抗原复合体与胴体瘦肉率关系的初步研究

A PRIMARY STUDY OF RELATIONSHIP BETWEEN SWINE LYMPHOCYTE ANTIGEN AND CARCASS LEAN MEAT PERCENTAGE

对33头长白猪的白细胞抗原复合体(SLA)和胴体瘦肉率之间的关系进行了研究。单因子最小二乘方差分析表明,血清单倍型H8(3.19)、H23(2.89)、H12(2.63)、H22(1.96)和H34(1.74)等对胴体瘦肉率表现出正效应值,而H1(-4.33)、H19(-4.28)、H33(-2.15)和H3(-1.57)等表现出负效应值。Q检验结果,具有单倍型H12、H22的肉猪其胴体瘦肉率高于具有单倍型H1、H19、H33、H3的肉猪(P<0.01),具有单倍型H8、H23、H34和H42的肉猪其胴体瘦肉率高于具有单倍型H1、H19和H33的肉猪(P<0.05)。

Relationship between the swine lymphocyte antigen (SLA) serological haplotypes of 33 Landrace pigs and their carcass lean meat percentage were studied and the data were analyzed with single least square analysis of covariance. The result indicated that haplotypes H8(3.19), H23(2.89), 11112(2.63), H22(1.96) and H34(1.74) showed positive effects on their carcass lean meat percentage while H1(-4.33), H19(-4.28), H33(-2.15) and H3(-1.57) negative effects. Through the Q-test, it was found that, the lean meat percentage of pigs with haplotypes H12 and H22 was significantly higher than that of those with haplotypes H1, H19, H3 (P<0.01), respectively whhle pigs with haplotypes H8, H23, H34 and H42 had significantly higher lean meat percentage than those with haplotypes H1, H19 and H33(P<0.05)
