摘要
本试验测定了玛纳斯萨福克羊与新疆细毛羊级进杂交3个世代共154只生产母羊体重、体尺等生产性能指标,结果显示:级进一代、二代、三代母羊平均体重在1.5岁、2.5岁、3.5岁等3个不同年龄阶段之间差异不显著(P>0.05)。3个年龄段体重与各项体尺指标呈极显著相关(P<0.01),与被毛细度差异不显著(P>0.05)。3个世代级进杂交群体被毛细度变化不明显,基本为58支。
The paper measured weight,size and other performance indices of three grading hybridizations of Manasi Suffolk sheep and Xinjiang fine-cool sheep,involving 154 ewes.It was found that the difference of average weight of first grading,second grading and third grading ewes at three different ages,that is 1.5,2.5 and 3.5 years old,is not obvious(P>0.05),at the said three ages,weight was closely related to size(P<0.01),while it was different for wool fineness(P>0.05).The wool fineness of the three grading hybridizations changed slightly,basically 58 count.
