A genome-wide scan was performed to detect quantitative trait loci (QTL) for resistance to the gastrointestinal nematode Haemonchus contortus in a double backcross population of Red Maasai and Dorper sheep. The mapping population comprised six sire families, with 1026 lambs in total. The lambs we...

Village- and central nucleus-based schemes were simulated and evaluated for their relative bio-economic efficiencies, using Ethiopia's Menz sheep as example. The schemes were: village-based 2-tier (Scheme-1) and 1-tier (Scheme-2) cooperative village breeding schemes, dispersed village-based nucle...

Based on the results of participatory approaches to define traits in the breeding objectives, four scenarios of ram selection and ram use were compared via deterministic modelling of breeding plans for community-based sheep breeding programmes in four diverse agro-ecological regions of Ethiopia. ...

An in vitro study was conducted to evaluate the optimum roughage to concentrate ratio in complete rations using unconventional sweet sorghum bagasse (SSB), a by product of ethanol industry as sole roughage source. Eight rations were prepared with roughage to concentrate ratio of 100:0 to 30:70. S...

We evaluated the efficiency of selection for body weight in a cooperative village breeding program for Menz sheep of Ethiopia under smallholder farming system. The design of the program involved organizing villagers in a cooperative breeding group to implement selective breeding of their sheep. T...

Feed shortage and poor quality of available feeds are major constraints for livestock production in the highlands of Ethiopia. A trial was conducted to assess if producing irrigated oat-vetch fodder during the dry period could adequately supplement the diet of fattening sheep and generate additio...

The fodder value of sweet sorghum bagasse with leaf residues (SSBLR) remaining after juice extraction for bio-ethanol production as major diet ingredient was assessed in male growing sheep measuring intake, digestibility and growth rates. The SSBLR contributed about 450 g/kg in total mixed ration...
