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

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

摘要:

本文试验探究特克赛尔羊、哈萨克羊、特哈杂交F₁，特哈杂交F₂、级近F₂、回交F₂、横交F₂等不同杂交模式下生产的公羔和母羔的生产性能分析和血液生理生化分析。研究结果表明，不同杂交代次绵羊群体血液生化指标存在差异，引入品种和杂交改良群体对本地适应性、抗病力和自身免疫力也存在差异。不同杂交方式产出的羔羊生产性能也有差异，杂交F₁代具有最明显的杂种优势，是最经济的杂交方式。为哈萨克羊的肉羊杂交育种提供理论依据。

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.
