药用植物添加剂在畜禽养殖中的研究进展OA

With the rapid development of the livestock and poultry industry,safety issues caused by the over-use of antibiotics pose a serious threat to human health.Under the policy framework of reducing and ban-ning antibiotics in feed,the development of green,safe,and efficient feed additives has become an inevi-table choice.Medicinal plant additives,with their natural and multifunctional characteristics,are consid-ered the best alternatives to antibiotics.This paper reviews the types,active ingredients,and pharmacologi-cal effects of medicinal plant additives,and based on recent studies,describes their application in the farm-ing of major livestock and poultry such as ruminants,pigs,and chickens,aiming to provide a theoretical ref-erence for the ecological development of livestock and poultry farming.
