| 摘要: |
| 奶山羊具有明显的季节性发情的特点,在非繁殖季节里,泌乳母羊体内的催乳素水平要高于繁殖季节,从而抑制了卵巢的生理机能。本研究采用具有抑制催乳素分泌作用的溴隐亭(CB-154,Parlodel)药物来降低母羊体内的催乳素水平,配合使用促性腺激素,提高泌乳母羊的诱发发情率,使配种后不返情率达到80％(28/35)。 |

| Abstract: |
| Milk goats are seasonal breeders apparently. The prolactin (PRL) level in naoestrus season is higher than that in breeding season in serum. And therefore, the physiological activity of ovary is inhibitated. In his experiment does were treated with reproduction hormone and bromocriptine or parlodel (CB-154)- inhibitor of PRL secretion to decrease PRL level in serum of doe.This increased the effects of oestrus induction in milk goats, with the NR rate of 80%(28/35) after mating. |
