CANATE GONZALEZ, Abid Silvestre; HERRERA DEMARES, Patricia; VILLALBA ESCOBAR, Luisa e HOZ, Daniel de la. EFFECTS OF ANTIPARASITIC COMMONLY USE IN SHEEP FARMS. Investig. andina [online]. 2020, vol.22, n.40, pp.185-194. Epub 18-Jun-2020. ISSN 0124-8146.
Introduction:
Parasitic disease are the most important and frequent cause of sanitary and economic problems in the national sheep farms.
Objective:
To determine the effectiveness of anthelmintics commonly used in gastrointestinal parasites from sheep farms in Valledupar, Cesar.
Method:
The study was realized with 340 sheep, divided into 4 farms (control, albendazole, fenbendazole, and levamisole). Sheep with a moderate parasite load were selected and treatment with an-thelmintic, post-treatment sampling was applied (15 days). Nemato-des in the infective stage (L3) were evidenced by stool culture.
Results:
Groups treated with fenbendazole, albendazole and levamisole had an effectivity of 44%, 65% y 84% with an inferior limit (95% conf.) of 60%, 70%, and 86%, respectively. Nevertheless, significant differences were evidenced (p < 0,05) in each group and between the treated groups. Cooperia curticei, Haemonchus contortus, Strongyloides papillosus, Trichostrongylus sp., and Ostertagia sp. larvae were found.
