新疆细毛羊早期不同年龄间生产性状的相关估测
The Estimate of Correlation Coefficient of Productive Traits between Different Ages in Xinjiang Fine Wool Sheep at Early Ages
【摘要】 通过对新疆南山种羊场1994年出生的新疆细毛羊的 9月龄的羔羊和15月龄的育成羊分别测定其重要经济性状,并进行性别内相关分析,得出如下结论:9月龄羔羊和15月龄育成羊间的毛束长度、净毛质量的相关系数均高于0.6,而体质量、纤维直径的相关数则大于0.3。
【Abstract】 The important economic traits of 9 month old lamds and 15month old hoggets of Xinjiang fine wool sheep were estimated and the correlation coefficient within sex were calculated. The results indicated that the correlation coefficient of staple length and clean wool weight were higher than 0.6 and that of body weight and fiber diameter were higher than 0.3 between 9 month old lamds and 9 month old hoggets.
