| 摘要: |
| 利用聚丙烯酰胺凝胶电泳分析225只西农萨能奶山羊乳样，首次对山羊乳中主要蛋白质的多态性与乳成分、产奶量等产奶性能指标的关系进行探讨。结果表明，β－乳球蛋白的基因型对奶山羊产奶量有显著影响，而α－酪蛋白、k－酪蛋白对产奶性能无显著影响作用，β－乳球蛋白ＢＢ型、α－酪蛋白BB型和k－酪蛋白AA型山羊个体表现出较好的产奶性能。 |

| Abstract: |
| Milk samples from 225 Xinong Saanen dairy goats were analysed in this
study using vertieal polyacrylamide一gelelectrophoresis in contiunous buffer system.
The polymorphism of milk protein and its relationships with milk production and milk
composition was statistically analysed for the first time in China.The results showed
that the genotype of α-CN and k-CN do not have much effect on the dairy performance,but that of β-Lg has the significant influence on milk production.Statistical
analysis also indicated that the individual goat with the genotype of β一Lg BB,α一CN
BB or k一CN AA demonstrated the better dairy production performance. |
