Admixture and selection offer insights for the conservation and breeding of Guyuan cattle.

ABSTRACT:

Background

The admixture between taurine and indicine cattle increases breed diversity and provides new genetic resources for human and natural selection. The climate of northwestern China is typified by cold and arid conditions, and cattle in this region are primarily taurine breeds. However, Guyuan cattle inhabit a transitional zone in northwestern China, typified by semi-arid and semi-humid climates. It is hypothesized that Guyuan cattle have a little of indicine ancestry. These results suggest that Guyuan cattle are a valuable genetic resource.

Results

We established a conservation population of Guyuan cattle in their native habitat. We found that Guyuan cattle were an admixture between 78.09% East Asian taurine (EAT) and 20.26% East Asian indicine (EAI) ancestries. The
