The results indicated that IMF of Meishan, Ningxia Black and Duroc were higher than that of Landrace and Yerkshire(P<0.05).
结果表明，梅山猪、宁夏黑猪和杜洛克猪肌内脂肪含量高于长白猪和约克夏猪（P<0.05）。
Thus, meat from Duroc pigs, characterized by a high intramuscular fat content, is much appreciated for both fresh consumption and its use in the production of high quality cured hams.
因此，以高肌内脂肪含量为特征的杜洛克猪肉，更受新鲜消费及制作高质量火腿生产者的青睐。
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。
The genetic variation of E. coli F18 receptor (ECF18R) loci in 867 pigs including Large Yorkshire, Landrace, Duroc, Ningxiang pig, Shaziling pig and Daweizi pig was detected by PCR-RFLP with Hin6 I.
采用PCR-RFLP技术检测了大约克、长白、杜洛克、宁乡、沙子岭和大围子6个品种共867头猪的E．coli F18受体（ECF18R）基因座的遗传变异。
