摘要： In this experiment, B. subtilis was added to pelletized straw-based total mixed ration, and the rumen microbial diversity of house-fed Duhan hybrid sheep was compared. Ten 3-month-old weaned Duhan hybrid lambs were separated into two groups and fattened for 80 days using a single-factor trial design. During the fattening period, the control and the experiment groups were fed with the same ration, except that the experiment group was supplemented with B. subtilis. The results showed that the addition of B. subtilis could significantly increase the daily weight gain, total weight gain, rumen microbial abundance, and rumen microbial diversity of the Duhan lamb. Among them, the proportion of microbial flora such as Bacteroidetes was significantly increased, producing more acetate, iso-butyrate, and butyrate, obtaining higher energy efficiency.
