肠道微生物缓解犊牛病原性腹泻的研究进展OA

Diarrhea is a common disease in calf breeding and is one of the major causes of calf mortali-ty,leading to decreased productivity and economic losses.The causes of diarrhea in calves are complex and can be classified into non-pathogenic and pathogenic.Pathogenic diarrhea is primarily caused by infections from viruses,bacteria and parasites.Studies have shown that diarrhea can trigger an imbalance in the in-testinal microbiota.Given that the colonization and development of the intestinal microbiota are crucial for calf health,regulating the intestinal microbial community through methods such as probiotics and fecal microbiota transplantation to alleviate diarrhea has become a hotspot at present.This paper reviews the characteristics of intestinal microorganisms in calves,microbial therapies for alleviating diarrhea,and methods for monitoring and predicting diarrhea symptoms.The findings are of reference significance for developing technologies and products based on intestinal microbiota to improve calf intestinal health and promote sustainable development of the livestock industry.
