| 摘 要： | 为筛选优化杂交组合，进行了杜洛克（杜）、大白（大）、长白（长）品种间杂交试验，测定了不同品种组合的生长速度、饲料转化率、胴体和肉质性状及其杂种优势率。结果表明，杜洛克、父系大白猪作终端父本与长大杂母猪杂交，其后代的日增重、饲料转化率、屠宰率、胴体长、眼肌面积、后腿比例、瘦肉率及肉质等主要性状均无显著差异。

| Abstract: | The experiment examined the crossbreeding effect of growth and meat production traits in crosses of Duroc, Large White and Landrace. The result of Duroc and Large White as terminal sire breeds to cross with Landrace×Large White sows showed the crossbreeding effect did not have significant difference in average daily gain, feed conversion, dressing percentage, carcass length, eye muscle area, ham percentage, lean percentage and meat quallty. |
