藏羊电刺激采精和人工授精技术

由于藏羊特殊的品种特性，高海拔严寒地区养殖适应性好，养殖成本相对其他类型羊较低，但自然交配情况下，空怀率高，繁殖率低。为克服藏种羊胆小易惊，调教不易，采精困难等不利因素，我们采用电刺激法促使种公羊被动排精，很大程度上降低了采精难度，提高了采精数量，在母羊集中发情季节，优秀种公羊个体可授配母羊500只以上，同时引进药物诱导母羊同期发情等技术进行人工授精，大大提升了藏羊繁殖性能，加速了我县藏羊引种改良进程，提高藏羊养殖经济效益。

Sperm Collection and Artificial Insemination Technology of Tibetan Sheep by Electrical Stimulation

Tibetan sheep have special breed characteristics, good breeding adaptability in high altitude and severe cold areas, and the cost of breeding is lower than other types of sheep. However, in the case of natural mating, the empty pregnancy rate is high and the reproductive rate is low. In order to overcome the unfavorable factors such as timidity, difficulty in training, and difficulty in semen collection of Tibetan sheep, we use electrical stimulation to promote the passive ejaculation of rams, which greatly reduces the difficulty of semen collection and increases the number of semen collection. In the concentrated estrus season of ewes, more than 500 ewes can be mated by individual outstanding rams. At the same time, artificial insemination is carried out by introducing drugs to induce ewes to be in estrus at the same time. This has greatly improved the reproductive performance of Tibetan sheep and accelerated the process of introducing and improving Tibetan sheep in our county. This improves the economic benefits of Tibetan sheep breeding.
