Study on Comparing Growth Performance,Carcass Traits and Meat Quality Among Landrace ×Yorkshire×Tongcheng,Yorkshire × Landrce × Tongcheng Hybrid Pigs and Their Parental Line
摘要
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.关键词
