| 摘要: |
| 利用聚丙烯酰胺凝胶电泳和统计模型方法对225只西农莎能奶山羊乳中主要蛋白质的特性进行了系统的遗传分析。结果表明，西农莎能奶山羊酪蛋白基因位点间具有显著的连锁关系；β－乳球蛋白（β－LG）和Ｋ－酪蛋白（K－CN）基因位点分别对305d产奶量、乳蛋白率和于物质率有显著影响，其中β－LGBB型和K－CNAA型个体表现出较好的泌乳性能。 |

| Abstract: |
| A systematic genetic analysis of the prineipal milk proteir,properties of 225 Xinong Saanen Dairy Goats was conducted by using PAGE and statistic model.The result showed that there were significant linkage relationships among the gene loci of casein of Xinong Saanen Goat.The gene locus of β－LG(Laetoglobulin) and K一CN
(Casein)had an obvious effeet on the 305d milk yield,milk protein pereentage and dry
matter Percentage,among which individuals with β－LG BB and K一CN AA demonstrated
a better milk Performanee. |
