Abstract: Chicken coccidiosis is a kind of parasitic disease which is caused by many coccidids of Eimeria mainly parasitizing intestinal epithelial cells,which seriously threatens the intestinal health of chickens.The severity of the disease is closely related to the variety and age of the host chickens,feeding management,feed nutrition,coccidia species,infection dose and other factors.Anticoccidiosis drugs are the main means to prevent and control coccidiosis,but drug resistance and drug residues are easy to appear in food safety problems. In recent years,plant extracts have attracted much attention in coccidiosis control due to their natural safety and nutritional health advantages.Plant extracts can intervene in different stages of coccidiosis life cycle to control coccidiosis,such as inhibiting the development of coccidiosis,destroying the physiological structure of coccidiosis,destroying the morphology of oocysts,so as to improve the antioxidant properties of chicken intestinal tract,improve its production performance and feed conversion efficiency.On the basis of not producing drug resistance,plant extracts can effectively control the spread of coccidia,reduce the harm of coccidia,enhance the immunity,and regulate the intestinal microflora.The author systematically reviewed the etiology of chicken coccidiosis,the factors affecting the severity of coccidiosis,and the application effect and mechanism of common plant extracts in the prevention,treatment and immune regulation of chicken coccidiosis,aiming to provide reference for the development and application of plant extracts in the prevention and control of chicken coccidiosis.
