中文摘要:

      夏洛莱肉牛引入新疆已有50余年的历史，为了验证新疆夏洛莱牛在塔额垦区的适应性，更好的开发利用新疆夏洛莱肉牛的种质资源，通过对新疆夏洛莱体尺和体重的测定和分析,以达到为新疆夏洛莱的选育和综合评价提供基础，推进新疆夏洛莱牛对哈萨克牛群体选育效果的目的。本试验方法：选取健康状况良好的导入夏洛莱外血培育后代新疆夏洛莱母牛567头进行了群体体重、体长、管围、胸围、体高等性状的调查。并与报道的西门塔尔牛与哈萨克牛杂交后代（简称西杂牛）、新疆褐牛与哈萨克牛的杂交后代（褐杂牛）做比较分析。采用excel（2019）进行统计分析，结果表明：导入夏洛莱外血培育的新疆夏洛莱牛体重、胸围、体高、体长均明显优于哈萨克牛；出生到3周岁之间，新疆夏洛莱牛在胸围和体重方面比西杂牛和褐杂牛有明显的优势。结论：新疆夏洛莱肉牛经过改良和选育，其生长性能有大幅度的提高，今后应积极运用现代育种技术，加强本品种的保护、选育和利用，构建地方特色肉用牛选育体系有积极的作用。
