Abstract

 

The review assesses Sheep Production System, Yield of Sheep Meat,
Chemical Composition, Preservation of Meat and its quality in Ethiopia. In
Ethiopia, Sheep production provides food, cash income and manure to the
smallholder farmers. Major feed resources in Ethiopia for sheep production are
natural pasture, crop residues, Aftermath, browse species and agro-industrial
byproducts and to a lesser extent improved pasture and forage crops. In the
country, the different types of sheep production system practiced accordingly
are: Highland sheep-barley system, mixed crop-livestock system, pastoral and
agro-pastoral production system, ranching, and Urban and peri-urban (UPU) sheep
production system. Ethiopia has a diverse indigenous sheep population numbering
28.89 million Sheep, excluding nomadic areas.         
 Meat production is depends up on different factors feed is one protein
and energy are limiting factors, so that supplementation of nutrient has shown
dramatic change on meat yield of the sheep in Ethiopia

 

Keywords: Ethiopia, sheep, chemical composition, meat preservation,
meat quality.
