外源褪黑激素对毛皮动物毛皮生长、生理与生殖的影响研究

本文论述了褪黑激素（ＭＴ）的发现及其意义,埋植ＭＴ植入物能促使水貂、貉、狐等毛皮动物冬皮不同程度的早熟,也能让绒山羊在非生绒期长绒,让安哥拉兔夏毛产量增加,同时影响毛皮动物生理与生殖。     

提高家畜繁殖学教学实习效果的改革与实践

针对目前西藏农牧学院动物科学专业家畜繁殖学课程教学实习中存在的主要问题,提出相应的改革措施,并在2013级动物科学本科1、2班中实施。结果表明,改革后学生在该课程的教学实习中表现出的动手能力、综合运用知识能力都得到了明显的提高。     

Reproduction in Domestic Buffalo

The domestic buffalo is an indispensable livestock resource to millions of smallholder farmers in developing countries, particularly in Asia. Although its reproductive biology is basically similar to that of cattle, there are important differences and unique characteristics that need to be considered in order to apply modern reproductive technologies to improve its productivity. Under most smallholder production systems, the reproductive efficiency of buffalo is compromised by factors related to climate, management, nutrition and diseases. However, when managed and fed properly, buffalo can have good fertility and provide milk, calves and draught power over a long productive life. The basic technical problems associated with artificial insemination in buffalo were largely overcome two decades ago, but the technology has not had the expected impact in some developing countries, because largely of infrastructural and logistic problems. Approaches involving the use of hormones for treating anoestrus and for synchronizing oestrus have had varying rates of success, depending on the protocols used and the incidence of underlying problems that cause infertility. Embryo technologies such as multiple ovulation embryo transfer, in vitro embryo production, cryopreservation and cloning are being intensively studied but have had far lower success rates than in cattle. Improving the productivity of buffalo requires an understanding of their potential and limitations under each farming system, development of simple intervention strategies to ameliorate deficiencies in management, nutrition and healthcare, followed by judicious application of reproductive technologies that are sustainable with the resources available to buffalo farmers.
