Compound antimicrobial peptide can repair intestinal injury in piglets

  News from our newspaper (reporter Cheng Ge, correspondent Zhang Mei)   Recently, a study by the subtropical Agricultural Ecology Research Institute of the Chinese Academy of Sciences confirmed that the compound antimicrobial peptide with antibacterial activity can repair the intestinal tract of weaned piglets and alleviate the toxicity of a series of pig farm diseases induced by vomit toxin to piglets The related research results were published in two articles in the Journal of Animal Science published by the American Society of Animal Sciences in October   Antimicrobial peptide is a kind of peptide with antibacterial activity, which is recognized as an effective substitute of antibiotics Vomitus toxin is a toxic secondary metabolite produced by Fusarium It is not easy to prevent because it is produced along with the growth of grain, which seriously affects animal health and food safety At present, there are many ways to control toxin pollution in feed production, but there are few studies on the resistance of animal body to toxin   The research team of yinyulong, a researcher of the Institute, established a toxin induction model by adding vomit toxin directly to the diets of weaned piglets, and fed a compound antimicrobial peptide containing lactoferrin antibacterial peptide, plant defensin and active yeast It was found that vomit toxin reduced the growth performance, immune function and antioxidant capacity of piglets, and increased the intestinal permeability and villi The growth performance, organ damage, immune and antioxidant function, intestinal morphology and protein synthesis of piglets can be improved by adding compound antimicrobial peptides   China Science Daily (2013-10-17, 4th Edition, comprehensive)
