Analysis of Performance and Blood Physiological and Biochemical Indexes of Kazak Sheep Crossbred Meat Sheep

Abstract:

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, backcross 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 adaptability, disease resistance and autoimmunity between introduced varieties and hybrid improved populations. There are also differences in the production performance of lambs produced by different crossbreeding methods. The F₁ generation has the most obvious hybrid vigor and is the most economical hybrid method. This provides a theoretical basis for crossbreeding of Kazakh sheep for meat.
