Abstract

Birth weights of 708 live piglets and weaning weights of 566 piglets were used to investigate the effect of the swine lymphocyte antigen (SLA) complex on these traits in Large White pigs. Piglets were from litters of a long-term selection experiment to measure response for selection to increase litter size. SLA haplotypes were determined using conventional class I antisera. A total of 14 haplotypes were detected. The effect of SLA haplotype on birth and weaning weights was investigated using a statistical model that included the effects of experimental group, sire, dam, sex and SLA haplotype. Results indicated that SLA class I haplotype 13.1.3 increased birth weights (P less than 0.10) and significantly increased weaning weights (P less than 0.01). This effect of haplotype 13.1.3 on weaning weight was 605 +/- 215 g (0.3 standard deviations). SLA class I homozygosity did not appear to affect birth and weaning weights. These results suggest that the SLA complex plays an important role in early growth in the pig and that further study of SLA effects on growth and reproduction are warranted.

摘要

708头活产仔猪的出生体重和566头仔猪的断奶体重被用于研究猪淋巴细胞抗原（SLA）复合体对大白猪这些性状的影响。仔猪来自一个长期选择实验的窝组，该实验旨在测定选择增加窝产仔数的反应。使用传统的I类抗血清确定SLA单倍型。共检测到14种单倍型。使用包含实验组、父本、母本、性别和SLA单倍型效应的统计模型，研究了SLA单倍型对出生体重和断奶体重的影响。结果表明，SLA I类单倍型13.1.3增加了出生体重（P<0.10），并显著增加了断奶体重（P<0.01）。单倍型13.1.3对断奶体重的这种影响为605±215克（0.3个标准差）。SLA I类纯合性似乎不影响出生体重和断奶体重。这些结果表明，SLA复合体在猪的早期生长中起重要作用，有必要进一步研究SLA对生长和繁殖的影响。
