不同杂交组合猪肥育性能与肉品质的研究

试验选用二元大长(Y×L)、三元杜长大(D×LY)、杜大长(D×YL)、三元皮大长(P×YL)4个杂交组合作为试验动物,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:D×LY、D×YL日增重、料重肉比及屠宰率最优,日增重、屠宰率与L×Y差异显著(P<0.05),D×YL屠宰率、眼肌面积分别为76.2%、47.62cm2,为4组合中最高,并与Y×L差异显著(P<0.05),与D×LY、P×YL组差异不显著(P>0.05)。

Study on production performance and meat quality of different crossbred swine

Four crossbred population including Yorkshire ×Landrace (Y×L), Duroc ×Landrace×Yorkshire (D×LY), Duroc ×Yorkshire×Landrace (D×YL)and Pretrain pig ×Yorkshire ×Landrace (P ×YL),were chosen as experimental populations. The growth performance, carcass quality of four crossbred were analyzed. The results indicated that: D×LY 、D×YL was the best on the average -day gain, the feed/gain ration and the slaughter ration, and there were significant difference between (D×YL) and (L×Y). The dressing percentage and eye muscle area (PD×LY)were 76.2%and 47.62cm2, and it was the highest in four combinations. There were significant difference with (L×Y) (P<0.05), and no difference with (D×LY)(P>0.05).
