Serum enzymes were studied in 377 apparently healthy sheep from three indigenous sheep breeds of Ethiopia. The effect of breed, age, sex and season on alanine aminotransferase (ALT)/glutamic pyruvic transaminase (GPT), aspartate aminotransferase (AST)/glutamic oxalacetic transaminase (GOT), alkal...

Data from 454 Menz and Horro male sheep at Debre Berhan Research Station, Ethiopia, were evaluated for slaughter characteristics. Rams were born from October 1992 to July 1996 and reared together from birth to slaughter at about 17 months of age. Pre-slaughter live weight (PSW) was about 25 kg, w...

The effect of subclinical artificial nematode parasite infection on dry matter intake (DMI), apparent digestibility (AD), efficiency of feed utilisation (EFU), plasma protein (PPC) and albumin concentrations (AC) was examined in lambs of the Horro and Menz breeds. The factorial experimental desi...

Over the last two to three decades, West Africa has witnessed considerable changes in land use. Unprecedented increases in human population combined with changes in climatic patterns have reduced per capita arable land traditionally available for agricultural production. In the livestock sub-sect...

Ethiopia has a large farm animal genetic diversity. The existence of this diversity is due in large part to its geographical location near the historical entry point of many livestock populations from Asia, its diverse topographic and climatic conditions, the huge livestock population size and th...
