Supplementary feeding of cattle-yak in the cold season alters rumen microbes, volatile fatty acids, and expression of SGLT1 in the rumen epithelium.

ABSTRACT: Cattle-yak, a hybrid offspring of yak (Bos grunniens) and cattle (Bos taurus), inhabit the Qinghai-Tibet Plateau at an altitude of more than 3,000 m and obtain nutrients predominantly through grazing on natural pastures. Severe shortages of pasture in the cold season leads to reductions in the weight and disease resistance of grazing cattle-yak, which then affects their production performance. This study aimed to investigate the effect of supplementary feeding during the cold season on the rumen microbial community of cattle-yak. Six cattle-yak (bulls) were randomly divided into two groups-"grazing + supplementary feeding" (G+S) (n = 3) and grazing (G) (n = 3)-and rumen microbial community structure (based on 16S rRNA sequencing), volatile fatty acids (VFAs), an
