Bacillus subtilis soluble water 100CFU/G for feed As a feed additive, spores are living cells that are in a dormant state and can withstand the high temperature, high pressure, and acid-base environments during feed processing, making them stable and easy to store. Bacillus subtilis exists in the form of spores in feed formulations and can enter the animal intestines in a live state for survival and reproduction, making it suitable for feed processing. Bacillus subtilis showed high survival rates in 90 ℃ high temperature, simulated gastric pH, pig bile salt test, and antibiotic susceptibility test; The preparation experiment of Bacillus subtilis preparation showed that the spore rate after drying and crushing treatment was greater than 98%. It can regulate the gut microbiota of livestock and poultry, increase the content of beneficial bacteria in the gut, and thus enhance the animal's resistance; It can be used in aquaculture to purify water quality and reduce harmful substances such…
