【摘要】：本试验选取2个苏姜猪扩繁场进行测定,观察苏姜猪的环境适应性和生产性能。结果显示:苏姜猪表现出良好的繁殖、生长性能,经产母猪平均产仔数达到13.51头;生长肥育猪30~90 kg阶段平均日增重达到678.06 g,料重比3.19。与长白猪杂交F1代,30~90 kg阶段平均日增重分别达到706.73 g,料重比3.05;但与皮特兰杂交F1代生产性能较差。因此,在苏姜猪扩繁推广中,建议使用长白猪杂交生产商品猪,不建议使用皮特兰公猪杂交。
[Abstract]:In this experiment, two Sujiang pigs were selected to test the environmental adaptability and production performance of Sujiang pig. The results showed that Sujiang pig showed good reproductive and growth performance. The average litter size of sows was 13.51; The average daily gain of growing finishing pigs was 678.06 g and the ratio of feed to weight was 3.19. The average daily gain was 678.06 g during the period of 30g / 90kg and the F _ 1 generation was crossbred with Landrace pigs. The average daily gain reached 706.73 g and the ratio of feed to weight was 3.05 in the period of 30 ~ 90 kg. Therefore, it is suggested to use Landrace crossbred to produce commercial pigs, and not to use skin Teran boar crossbreed.
