Haematological parameters were studied in 377 apparently healthy sheep comprising three indigenous breeds of Ethiopia. The effect of breed, age, gender and season on the haematological values was assessed. There was significant (P<0.01) breed difference for all erythrocytic series. Red blood cell...

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...

An exploratory survey was undertaken to understand sheep production system, breeding practices and selection criteria for Ethiopian Menz and Afar sheep breeds in their home tract as a step towards developing sustainable sheep breeding strategies. The mean sheep flock size was 31.6 in Menz and 23....

A retrospective case-control study was conducted on 6718 sheep of two breeds (2772 Horro and 3946 Menz) on risk factors for mortality associated with respiratory disease (MARD) in Ethiopia, based on data collected between October 1993 and December 1997. Potential risk factors examined were breed,...
