| 摘要: |
| 于1994年4月份,采集安哥拉山羊、陕北黑山羊及其级进杂交后代的皮样,制作皮肤切片,进行皮肤及毛囊结构特征的观察研究。结果表明:随着级进代数的增加,杂交后代的毛囊密度、形态及结构与安哥拉山羊逐渐接近,到F3与安哥拉山羊基本一致,且具有较强的生长马海毛纤维的机能。培育新品种可以从F3开始横交固定。 |

| Morphological Change of Skin Follicle in Crossbred Angora Goats |
|
|
| Abstract: |
| The morphological structure of the skin follicle of Angora goats,North
Shaanxi local black goats and their crossbred goats were observed. The results showed
the follicle density and the morphological structure of the crossbredwere close to Angora goats along with upgrading, and when came to the 3rd generation, they were very similar to those of Angora goats and had a stronger productivity of mohair fibre.The breeding of the North Shaanxi Mohair Goat should centre on F3 for intermating. |
