Abstract

Abstract:

The study aimed to explore the genetic structure and bloodline composition of 4 local cattle breedings in Tibet. In this study, 22 plateau Holstein cattle, 20 plateau Jersey cattle, 45 American Brahmin cattle, 46 Yunnan Zebu and 11 Brahmen cattle as reference breeds, the samples to be tested were 177 cattle of 4 local breeds in Tibet. SNPs data were obtained by Illumina GGP100K chip hybridization, and the genetic structure and bloodline composition of SNPs were analyzed by MEGA X and Admixture. The results showed that Tibetan cattle had a closer genetic relationship with plateau Holstein cattle and plateau Jersey cattle than other local cattle breeds in Tibet. Some Zhangmu cattle and Apeijia cattle divided Tibetan cattle into two large subpopulations; There was a close genetic relationship between Shigatse hump cattle and Yunnan Zebu. In the Shigatse hump cattle population, the proportion of plateau cattle bloodline was more than 90%, in the Apaijia cattle population and Tibet cattle population, the proportion of plateau cattle bloodline was more than 50%, only in the Zhangmu cattle population, the proportion of plateau cattle bloodline was 33.15%. Secondly, bos indicus bloodline accounted for 18.27% in Zhangmu cattle population, while bos indicus bloodline was less (5%) in Apaijiza cattle, Tibet cattle and Shigatse hump cattle population. There were 35.94% dairy cattle bloodline in Apaijia population and 48.58% dairy cattle bloodline in Zhangmu population. This study provided important guidance for the future cross-breeding and cross-fixing of the native cattle species in Tibet, and also provided theoretical reference for the conservation and utilization of the resources of the two endangered breeds of Apaijiza cattle and Zhangmu cattle.

Key words: Apejiaza cattle, Zhangmu cattle, Tibetan cattle, Shigatse hump cattle, SNPs data, genetic structure, bloodline composition
