Multiomic Analyses Reveal the Effects of Supplementing Phytosterols on the Metabolic Function of the Rumen Microbiota in Perinatal Cows.

ABSTRACT: Phytosterols are natural steroids in plants, possessing bioactivities that could modify gut microbes. This experiment aimed to evaluate the effects of feeding phytosterols on the community structures and metabolic functions of the rumen microbiota in perinatal cows. Perinatal cows were supplied with 0 mg (control) or 200 mg (treatment) phytosterols per day. Multiomic analyses were used to analyze the community structures and metabolic functions of rumen microbiota. Results showed that dietary phytosterols increased the copy number of total ruminal bacteria, the concentration of microbial crude protein, and the molar percentage of propionate in the rumen of perinatal cows but had no effects on the alpha diversity of ruminal bacteria. However, they enriched three genera (i.e., Fibrobacter
