用“总适应能力”衡量羊品种引种效果的研究

总适应能力是指绵、山羊品种在被引入地区的自然生态环境和饲养管理条件相互作用下,所表现出的繁殖力、生产力和经济效果的总和,是衡量绵、山羊品种在被引入地区是否适应,及其适应程度的客观数量化指标。本文对总适应能力的组份,按其相对重要性进行剖分,并对其评定项目、计算得分方法和相应的总适应能力等级进行了阐述。

Study on the Effect of Introduced Sheep and Goat Breeds Measured by "The General Adaptability

The general adaptability means the total of reproductivity, productivity and economic efficiency showed under the interaction between the natural ecology environment and the raising-management condition in the areas where the sheep and goat breeds are introduced. It is the objective and quantitative index for measuring the adaptation and its degree about the sheep and goat breeds in introduced areas. The article analyzed the components of the general adaptability according to their relative importance and stated the evaluation items, the reckoning and the gradation of the general adaptability as well.
