摘　　要：以莱芜猪为育种素材采用继代选育方法选育6个世代培育出了具有繁殖哺育率高、适应性抗逆性强和肉质优良的配套系专门化母本新品系ZML。窝均产仔(14.82±0.27)头,70日龄育成率90.90%,育肥猪肌内脂肪(9.78±1.74%)。筛选的"ZFD♂Х(ZFY系♂ХZML系♀)♀"配套系育肥猪日增重742 g,料重比2.99:1,胴体瘦肉率58.39±4.40%,肌内脂肪4.01%。推广应用效果良好。Laiwu pig was used as breeding material in this study, a new special dam line - ZML was established after six generations selecting and breeding; and ZML has the characters of high reproductive and breast - feeding rate, adaptive strong resistance and great meat quality. The mean litter size was 14.82 0.27 and incubator rate at Day 70 was 90.90%, the intramuscular fat content of adult pig was 9.78 1.74%. The performance of fatten pig from cross combination - ＂ZFD ♂ X（ZFY ♂ XZML ♀ ） ♀ ＂ synthetic line was great, their daily gain, feed - weight ratio, carcss lean rate and intramuscular fat content was 742g, 2.99 ： 1,58.39 ±4. 40% and 4.01%, respectively. The effect of promotion and utilization is very satisfactory.
