Description

technical field [0001] The invention relates to a feed additive for weaned piglets and a preparation method thereof, in particular to a feed additive for weaned piglets which can control respiratory diseases and improve immunity, and belongs to the field of feed additives. Background technique [0002] For a long time, people have been adding antibiotics and antimicrobial drugs to animal feed to control common diseases such as diarrhea and respiratory diseases, so as to maintain health, promote growth and improve feed utilization. However, when a large number of drugs such as antibiotics are used to suppress pathogenic microorganisms, it also suppresses the balance of physiological microorganisms in animals, which leads to the susceptibility of animals, especially young animals, to pathogenic microorganisms. At the same time, the long-term use of antibiotics and antibacterial drugs will lead to the emergence of drug-resistant strains, that is, "super bacteria", and these dru...
