犊牛腹泻的常见病因及中兽药防治研究进展OA

Calf diarrhea lead to reduced growth performance,weakened immunity,and even death in calves.Some zoonotic pathogens also threatened public health,severely impacting farming profitability.Causes included infectious and non-infectious factors.Infectious agents encompass bacteria,viruses,and parasites,while non-infectious factors involve low immunity,environmental stress,and nutritional imbalance.Clinical symptoms vary depending on the underlying cause.Compound Chinese veterinary medicines,with their multi-target synergistic effects,had become the preferred choice for preventing and treating calf diarrhea.Studies indicated that adding Tavaxaci Herba extract,Glycyrrhizae Radix et Rhizoma extract,ginger extract,Perillae Fructus extract,and various Chinese herbal polysaccharides to feed could reduce the incidence of calf diarrhea on farms.These compound veterinary herbal medicines improved calf diarrhea by regulating immune function,repairing the intestinal mucosal barrier,and modulating gut microbiota balance.Future research should focus on pattern differentiation and holistic efficacy studies in veterinary traditional Chinese medicine,optimize formulations for greater convenience,and prioritize prevention over treatment by enhancing husbandry management to improve control outcomes.
