Abstract

Objectives The epidemic situation of parasitic diseases in sheep in Yulin City, Shaanxi Province, and the awareness of prevention and control of farmers (farms) regarding these parasitic diseases was accurately understood to reduce the risk of parasitic diseases in sheep and promote the healthy development of local sheep industry. Methods A survey was conducted from June to July 2024 on 240 sheep farms (households) in 12 counties (cities, districts) of Yulin City with a combination of questionnaire survey and laboratory testing. Simultaneously, 360 samples of sheep feces and 360 samples of sheep blood were collected for laboratory analysis. Results All 240 sheep farms (households) conducted deworming work on their sheep. Among them, 237 farmers dewormed their sheep 1-3 times a year, mainly using western medicines such as ivermectin, administered by oral or intramuscular injection. The results of fecal examinations showed that the infection rate of nematodes, trematodes, cestodes, and coccidia was 41%, 31%, 17%, and 76%, respectively. The infection of coccidia and nematodes was relatively severe, and no echinococcosis was detected in the serum testing. Conclusions Although the deworming rate of all livestock farms (households) in the city has reached 100%, most of them have a single choice of deworming drugs and insufficient knowledge of prevention and control. The infection situation of parasitic diseases in sheep is still complex, and knowledge training should be strengthened, management of farming should be optimized, and measures for prevention and control should be intensified.
