| Abstract: | Yak （Bos grunniens） is the unique genetic resources on Qinghai Tibetan plateau and also the basic production and living materials in high and cold pastoral area. Reproduction is the key procedure in yak production. To study reproductive characteristics is the basic to implement reproductive regulation and control of female yak. The paper summarized the reproductive characteristics from the aspects of puberty, sexual maturity, estrus, gestation period, parturition, reproductivity, and so on. It also analyzed the technical measures on how to improve the efficiency of artificial insemination, which aimed to provide tech- nical information for breed improvement of yak. |
