| 摘要: |
| 对西北农大试验农场95只1,2胎莎能母羊的乳房进行了分类,并分析了不同乳房类型与90天产奶量。奶中营养成分以及乳房评分间的相关关系,结果表明:莎能羊正常乳房可分为球形、卵形和梨形三种类型,不同类型乳房的个体间产奶量存在着显著的差异,其中以梨形乳房的个体产奶量最高,球形乳房最低;而不同类型乳房的个体间乳中主要营养成分,乳房评分无明显差异。这对于今后奶山羊乳房的选择,提高母羊产奶性能具有重要的指导意义。 |

| Abstract: |
| The under shapes of 95 Xinong Saanen milk does were classified and the correlated relation between udder shapes and milk yields in 90 days, the composition of milk and the scores of tinders were analysed in this paper.The results show that the udder shapes of Saanen milk does can be classified into three types, ball, egg and pear types. There is a significant difference in milk yields among three udder types, of which, the pear-shaped udder has the highest miik production, but the ballshaped udder has the lowest milk production. There is no significant difference in milk composition and udder scores among three udder types. The research results are of the important significance in the selection of udder shapes and the improvement of milk production of the does in the futurs. |
