Abstract

Parasitic nematodes are one of the main health and production constraints of sheep worldwide. We used a questionnaire survey to assess farmers’ knowledge about gastrointestinal nematodes (GIN) of sheep, current control practices and preferences for control methods between farmers involved and not involved in community-based breeding program (CBBP) in two different locations, Bonga and Horro, Ethiopia. A total of 240 households were interviewed. Farmers associated transmission of GIN with ingestion of grass. CBBP farmers (55 and 85.7%, respectively, in Bonga and Horro) use anthelmintics (AH) at least four times per year per animal compared to non-CBBP farmers (15 and 52.5%, respectively in Bonga and Horro). The farmers in CBBP had incorrect perception pertaining to sustainability of anthelmintics for control of GIN in sheep suggesting awareness creation should be done on the threats of anthelmintic resistance. Selective breeding (SB) was preferred as a sustainable option for control of GIN of sheep more significantly (mean score = 4.03 vs. 2.43, p<0.001) by CBBP than non-CBBP farmers in Horro. This suggests that there is possibility to introduce SB in CBBP. In conclusion, CBBP farmers practice AH treatment more frequently than the non-CBBP farmers. To reduce risk of development of anthelmintic resistance, taking into account the inclusion of nematode resistance trait into the CBBP is crucial.
