Abstract: Disclosed are Lactobacillus rhamnosus strain 753 and uses thereof, a silage additive and silage. Lactobacillus rhamnosus strain 753 is deposited in China General Microbiological Culture Collection Center with an accession number of CGMCC 18233. Lactobacillus rhamnosus strain 753 can improve the quality of silage in a high-temperature and high-humidity region, and the silage processed by Lactobacillus rhamnosus strain 753 has good stability and low pH, low aflatoxin B1 content and less dry matter loss. In addition, secondary fermentation can be avoided in the silage processed by Lactobacillus rhamnosus strain 753 when a silo or bale for silage is opened.
