西藏昂仁县黄牛人工授精率改良现状及提高措施

西藏日喀则黄牛是乳、肉、役兼用的小型地方原始品种,简称西藏牛,该牲畜品种适应高原气候,耐粗饲,管理较为粗放,抗逆性较强,但是由于该黄牛品种个体较小,性成熟较晚,整体的生产性能低下,严重影响到养殖户的经济效益。目前在西藏日喀则昂仁县黄牛人工授精技术已初步形成体系,人工授精率逐年上升,但是在具体的操作中,由于很多技术人员存在诸多不规范的行为,黄牛的受胎率时好时坏,严重影响品种改良进程。该文主要论述影响西藏昂仁县黄牛人工受精率的因素,提出相应的工作措施。

Present Situation and Improvement Measures of Artificial Insemination Rate of Yellow Cattle in Angren County,Tibet

The Tibetan samzhubzêdistrict cattle is a small local original breed used for both milk,meat and service,which is called the Tibetan cattle for short.The cattle breed adapts to the plateau climate,is tolerant to coarse feed,has extensive management and has strong resistance to adversity.However,due to the small individual size of the cattle breed,late sexual maturity,the overall production performance is low,seriously affecting the economic benefits of farmers.At present,the technique of artificial insemination for cattle in Angren county,Xigaze city,Tibet has taken initial shape,and the rate of artificial insemination has been increasing year by year.However,in the specific operation,due to many technical personnel's non-standard behaviors,the conception rate of yellow cattle varies from time to time,which seriously affects the process of breed improvement.In this paper,the factors affecting the artificial insemination rate of ngamring county yellow cattle in Tibet were discussed,and the corresponding measures were put forward.
