Bacillus coagulans is not in the list of feed additives of the Ministry of Agriculture. A company has applied for patent protection for the application of this strain in feed, but it has not expired yet. Bacillus coagulans has no great advantage in feed application, and its function can be replaced by other Bacillus (such as Bacillus subtilis and Bacillus licheniformis allowed by the Ministry of Agriculture). This strain has been used in medicine.
