| 摘 要： | 试验以通城猪为母本，长白猪（瑞典）、大白猪（英国）为父本进行三元杂交，对两个三元杂交猪（长×（大×通）、大×（长×通），简称为长×大×通、大×长×通）及亲本分别从生长性能、胴体性状及肉品质方面进行了比较。结果显示，长×大×通和大×长×通三元杂交猪的生长性能、胴体性状及肉品质均表现出较好的杂种优势。长×大×通三元杂交猪的测定期平均日增重、料重比、活体背膘厚、剪切力、大理石纹和肌内脂肪含量的杂种优势率分别为12.54%、-13.89%、10.39%、-8.71%、-8.33%和8.57%，大×长×通的杂种优势率分别为10.81%、-11.05%、10.55%、-6.50%、6.67%和2.44%。长×大×通和大×长×通两者比较，长×大×通三元杂交猪的试验期平均日增重、眼肌面积及腿臀肉骨率分别为843.4 g/d、34.51 cm2和73.54%，大×长×通三元杂交猪分别为808.6 g/d、31.45 cm2和70.67%，二者差异均显著（P<0.05）。综上所述，以通城猪为母本进行的两个三元杂交猪的生长和胴体性状显著优于亲本通城猪，肉质显著优于亲本长白猪和大白猪，且长×大×通组合优于大×长×通组合。 |

| Abstract: | The breeding experiment was carried out based on Tongcheng pig which were female paternal lines while Landrace pig and Yorkshire pig were male paternal lines,and two hybridization combinations Landrace×(Yorkshire×Tongcheng) and Yorkshire×(Landrce×Tongcheng) (LYT and YLT) were got. The growth performance,carcass traits and meat quality of both parent and offspring were determined. The results suggested that two hybridization combinations LYT and YLT showed significant heterosis in growth performance,carcass traits and meat quality. The relative heterosis of average daily gain during the trial,feed to gain ratio, average of live backfat thickness,muscle shear force,marbling score and intramuscular fat content were 12.54%,-13.89%,10.39%,-8.71%,-8.33% and 8.57% in LYT,and that were 10.81%,-11.05%,10.55%,-6.50%,6.67% and 2.44% in YLT,respectively. The average daily gain during the trial,loin eye area and lean and bone of the ham proportion were 843.4 g/d,34.51 cm2 and 73.54% in LYT, and those were 808.6 g/d, 31.45 cm2 and 70.67% in YLT,and there were significant difference among the indexes between the two hybrids (P<0.05). Finally,the study demonstrated that the three-way crossbred was better than Tongcheng pig in growth performance and carcass traits,and better than both of Yorkshire and Landrace in meat traits,furthermore,LYT were given a more general evaluation than YLT. |
