Abstract

The present invention discloses an antibacterial peptide immunomodulatory feed additive for pigs. The feed additive consists of the following components in parts by weight 1-5 parts of bacillus amyloliquefaciens SC06 at a concentration of 10^9 cfug, 1 part of pidotimod, 3 parts of zeolite powder, and 1-5 parts of corn starch. The antibacterial peptide immunomodulatory feed additive for pigs can overcome many problems including pig body immunosuppression, low disease resistance, slow growth, etc. in the current breeding process, and the antibacterial peptide immunomodulatory feed additive for pigs has characteristics of being easy in preparation, easy to use, significant in effects, etc., and thus is very good in promotion and use values.

Description

technical field [0001] The invention provides the preparation and application of a bacteriocin immunoregulatory feed additive for pigs. Background technique [0002] Immunosuppression is common in pig breeding at present, which is caused by various factors, including pathogenic bacteria infection (such as blue ear disease, circovirus disease, pseudorabies, swine fever, parvovirus disease, swine influenza, parvovirus virus and asthma, Haemophilus parasuis, infectious pleuropneumonia, salmonellosis, bacteria such as Eperythrozoonosis, and parasitic infections such as toxoplasmosis) and non-infectious factors, among which there are Toxin poisoning (mycotoxins: such as aflatoxin, zearalenone, T-2 toxin, fumonisin, ochratoxin, etc.), irrational use of antibiotics and drugs (such as chloramphenicol, furazolidone, streptoxin, etc.) neomycin, gentamicin, kanamycin, corticosteroids, tetracycline, oxytetracycline, prednisone, cortisone, androgens, testosterone, sulfa drugs, etc.), nu...
