特克塞尔、杜泊及其杂交一代生长发育的研究

Research on the growth and development of Texel,Dorper,short-tailed,their crossbred F_1

本试验选用特克塞尔(Ⅰ组)、杜泊(Ⅱ组)、特克塞尔与小尾寒羊杂一代(Ⅲ组)、杜泊与小尾寒羊杂一代(Ⅳ组)和小尾寒羊的羔羊(Ⅴ组),共125只。在饲喂相同的颗粒饲料和相同的管理条件下,测定各种羊的生长发育性能。结果表明,Ⅰ组羔羊的平均初生重为5.10kg,显著高于Ⅲ组、Ⅳ组和Ⅴ组,且Ⅲ组的平均初生重显著高于Ⅴ组。Ⅲ组、Ⅳ组0～3月龄日增重显著高于Ⅴ组,Ⅲ组、Ⅳ组3～6月龄和0～6月龄日增重显著高于Ⅰ组、Ⅱ组和Ⅴ组。

125 lambs are selected in this experiment,which included Texel lamb （groupⅠ）,Dorper lamb （groupⅡ）,the crossbred lamb F_1 from Texel and short-tailed as the female parent （groupⅢ）,the crossbred lamb F_1 from Dorper and short-tailed as the female parent （groupⅣ）,and short-tailed （groupⅤ）.Properties of the growth and development of these lambs are measured in the same diet and management condition.The results show that the average birth weight of groupⅠ（5.10kg） is obviously bigger than groupⅢ,groupⅣand groupⅤ.The average birth weight of groupⅢis also bigger than groupⅤ.The daily growth of groupⅢor groupⅣis more than groupⅤat the age of 0～3 months,and more than the other three groups at the age of 3～6 months or 0～6 months.
