1·There were no significantly differences in the relative weight of heart lung + trachea between wild boars and landrace pigs.
野猪的心、肺+气管相对体重均高于长白猪的相应指标，但差异不显著。
2·The results showed that the landrace grew rapidly, and the feed utilization rate and economic returns were high.
结果表明，长白猪的生长发育较快，饲料利用率和经济效益均较高。
3·There were no significantly differences in the relative weight of heart, lung + trachea between wild boars and Landrace pigs.
野猪的心、肺+气管相对体重均高于长白猪的相应指标，但差异不显著。
4·The effects of this SNP on backfat thickness in Landrace, Yorkshire and Duroc were estimated using least square method. The homozygote pigs had thicker backfat than the heterozygote ones.
用最小二乘法分析SNP对长白猪、约克夏猪和杜洛克猪的背膘厚的效应的结果表明，纯合基因型个体的背膘厚大于杂合基因型个体。
