摘要
本研究选用二元长大(L×Y)、三元杜长大(D×LY)、四元皮杜长大(PD×LY)三个杂交组合猪群为实验动物,进行生长发育性能、胴体品质性状测定,旨在为优质肉高效配套杂交组合筛选提供理论依据。研究表明:PD×LY日增重、料肉比及屠宰率最优,日增重、屠宰率与L×Y差异显著(P<0.05);PD×LY眼肌面积、后腿比例分别为48.09cm2、34.23%,为三组合中最高,并与L×Y差异显著(P<0.05),与D×LY组差异不显著(P>0.05)。
Three crossbred population including Landrace x Yorkshire （ L × Y）, Duroc x Landrace x Yorkshire （ D × LY） and Pretrain pig x Duroc x Landrace x Yorkshire （PD × LY）, were chosen as experimental populations. The growth performance, carcass quality of three crossbred commercial pigs were analyzed. The results indicated that ： PD x LY was the best on the average - day gain, the feed/gain ration and the slaughter ration, and there were significant difference between （ PD × LY） and （ L × Y）. The eye muscle area and the hind leg ration of（ PD x LY）were 48.09cm2 and 34.23%, and it was the highest in three combinations. There were significant difference with（ L×Y） （ P 〈 0.05 ）, and no difference with（ D × LY） （ P 〉 0.05 ）.
