Ruminants generally succeed in selecting an appropriate diet relative to their nutrient requirements, and macronutrients such
as energy and protein are considered as playing a primary role in their food preferences. Diet learning through post-ingestive
consequences, evidenced by many studies that...

Menz sheep are indigenous to the highlands of Ethiopia, and highly valued for their meat and wool production. The area is characterized as a low input mixed barley-sheep production system. In 1998, a selection experiment was setup to evaluate the response of Menz. sheep to selection for yearling ...

An investigation was made into the epidemiology of nematode infections of sheep in two districts of Jimma zone, southwestern Ethiopia. We used two approaches—long-term monitoring of identified sheep for nematode infection and abattoir or market survey for analysis. In the first monitoring regime,...

Microscopic examination of pneumonic lungs of the Ethiopian highland sheep (n = 35) was made and compared with the pneumonic lungs from ten sheep and 66 goats from the lowlands. Lesions compatible with sheep pulmonary adenomatosis (SPA; 8/35, 22.8%), and maedi-visna (MV; 9/35, 25.7%) were recorde...

The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn. Dorpers are regarded as early-maturing, and ewes lambed at an age of 1 year in one study. Age at first lambing was higher in other literature sources cited. The fertilit...
Examines the effects of supplementing diets based on common Ethiopian crop residues (teff, wheat and oat straws and maize stover) with different proportions of hay made from a common local clover, Triofolium tembense.
