摘要: 根据内蒙古敖汉细毛羊现行育种和生产条件下的育种技术参数、营养学参数和生产与市场经济学参数,采用“差额法”对内蒙古敖汉细毛羊的育种目标性状的边际效益进行了计算。通过各目标性状的边际效益标准化计算得到产毛性状、繁殖性状和生长发育性状之间的相对经济重要性之比约为7:2:1。若按照各类羊分别选择分开对待,则成年母羊约为10:5:1,育成羊则约为5:2:1。

Abstract: We have calculated marginal utility of breeding target characters of Inner Mongolian Aohan Merino Sheep with "difference method" acoording to breeding technique parameter,nutriology parameter as well as product and market parameter under breeding and production conditions at prese.We heve obtianed the results that the relative economic importance proportion is about 7:2:1 by standard calculating marginal utility of every target characters. This proportion is about 10:5:1 in adult ewe and about 5:2:1 in improved sheep if acoording to each kinds of sheep to be separately selected and separately treated.
