Effect of strategic helminthosis control on mortality of communally grazed Menz lambs of smallholders in the cool central Ethiopian highlands por Tibbo, Markos, Aragaw, K., Teferi, M., Haile, Aynalem

“…A 3-year longitudinal study was conducted to evaluate the effects of strategic anthelmintic dosing on communally grazed village sheep in Gera Keya district in the central highlands of Ethiopia. Ewes were stratified by weight and randomly allocated to three treatment groups: untreated control (TG1), twice-dosed per year (TG2; for both nematodes and trematodes in mid-January and mid-June) and four-time-dosed per year (TG3; in June for nematodes, in August–September for nematodes and adult Fasciola, in November–December and January–February for immature liver flukes). …”
