【摘要】 应用主因子分析的方法对 96头雷州山羊成年母羊的 8个主要体尺性状进行统计分析。结果表明 ,雷州山羊成年母羊的体尺性状可区分为相对独立的 3个主因子。第一主因子的贡献率为 6 0 .0 0 % ,是雷州山羊成年母羊体尺性状变异的主要来源 ,因此 ,在雷州山羊的选育工作中应以第一主因子为主体进行多个性状的集团选择 ,提高雷州山羊的选育效率。更多还原

【Abstract】 Statistical analysis was made of 8 characters related to body size of Leizhou nanny goats with principal factor analysis. The results identified 3 relatively independent principal factors for the body size. The first principal factor was found to contribute 60.00% to the body size variation of adult nanny goats, and therefore is recommended to be used in mass selection of nanny goats so as to increase breeding efficiency.更多还原
