摘要
采用金华猪和六白猪为母本,长白猪和巴克夏猪为父本,进行了4种杂交组合(长金、长六、巴金、巴六)猪的繁殖、生长、屠宰、肉质性能的研究。通过选育筛选和性能测定,长金猪在产活仔数(12. 51头),平均日增重(510. 38 g·d^(-1)),料重比(3. 52),瘦肉率(60. 27%),背膘厚(27. 32 mm),皮厚(3. 11 mm),大理石纹(2. 85),平均剪切力(15. 64 N),粗蛋白(260 mg·g^(-1))等指标显著优于其他杂交组合。通过4种杂交组合猪的性能测定,筛选出了长金猪作为最佳选育的商品代,为其在养殖场的推广应用提供了科学依据。
Performance of breeding,growth,slaughter and meat quality of four hybrid pigs were studied with Jinhua pig and six white pig as female parent,Landrace and Berkshire pig as male parent.The results showed that the indexes of Landrace×Jinhua hybrid pigs,inculding number of born alive(12.51),daily weight gain(510.38 g·d^-1),feed to gain ratio(3.52),lean meat rate(60.27%),backfat thickness(27.32 mm),skin thickness(3.11 mm),armbling score(2.85),average shearing force(15.64 N),crude protein(260 mg·g^-1)were significantly superior to other hybrid combinations.Through performance measurement of four hybrid pigs,the Landrace×Jinhua hybrid pig was selected as the best commodity substitute,which provided scientific basis for its application in the farm.
