| 摘 要： | 通过引进贾洛羊种公羊杂交改良甘加羊,对贾甘F1代与甘加羊生长发育进行对比研究。结果显示:从初生至18月龄贾甘F1代羊生长发育较快,与甘加羊比较体重差异极显著(P<0.01);体高、体长、胸围、管围分别比甘加羊均有显著或极显著地提高。贾甘F1代羊和甘加羊绝对生长在6月龄为最大,达到绝对生长高峰,贾甘F1代羊日增重为162.22g,甘加羊日增重为150.11g。相对生长系数随日龄的增加而下降,体重的生长强度随月龄的增加逐渐减小。

| Abstract: | Jialuo Sheep was introduced to improve Ganjia Sheep,and comparative research on growth and development per- formance was conducted between Ganjia Sheep and Ft generation from from Jialuo and Ganjia Sheep hybridization. The results showed that F1 grew faster than Ganjia Sheep （P〈0.01）. Height,length,heart girth, circumference of cannon hone improved also. Absolute growth index of F1 and Ganjia Sheep reached peak on 6-month age,daily weight gain of F1 and Ganjia Sheep was 162.22 g and 150.11 g, respectively. Relative growth index and growth intensity decreased with the increasing of age. |
