哈萨克羊杂交肉羊生产性能和血液生理生化指标的分析研究OA

This experiment explores the production performance analysis and analysis of male and female lambs produced under different crossbreeding modes such as Texel sheep,Kazakh sheep,Teha cross F1,Teha cross F2,near-class F2,back-cross F2,and cross F2.Blood physiological and biochemical analysis.The research results show that there are differences in blood biochemical indicators among different cross-generation sheep populations.There are also differences in local adaptabili-ty,disease resistance and autoimmunity between introduced varieties and hybrid improved populations.There are also differ-ences in the production performance of lambs produced by different crossbreeding methods.The F1 generation has the most ob-vious hybrid vigor and is the most economical hybrid method.This provides a theoretical basis for cross-breeding of Kazakh sheep for meat.
