为探讨母系不同性状对半罗、半考的遗传影响,我们用陵川种羊场和七个生产队的育种资料进行了统计分析。结果表明,母系的羊毛长度、细度、剪毛量,体重等性状对后代均有一定影响。在上述性状中,应抓住细度这一重要环节,母系细度以58—60支为最适宜,这样可以加快育种步伐。通过母系三种类型被毛品质的综合比较,以股部不同质为最好。采用细度(58—60支)和被毛品质(股部不同质)相结合的方法是培育半细毛羊的有效途径。
In order to investigate the genetic effects of different maternal lines on semi-Luo and half-test, we conducted statistical analysis using the breeding data of Lingchuan breeding farm and seven production teams. The results showed that the maternal wool length, fineness, shear weight, weight and other traits have some influence on the offspring. In the above traits, we should seize the fineness of this important part of the maternal fineness of 58-60 for the most appropriate, this can speed up the breeding pace. Through the matriarchal three types of gross quality of the overall comparison, the stock is not the best quality. The use of fineness (58-60) and the quality of the coat (the stock is not homogeneous) method is to cultivate semi-fine wool sheep an effective way.
