Cost-effective genotyping of livestock species can be done through a process which involves genotyping part of the population using a high density (HD) panel and the remainder with a lower density panel and then use imputation to infer the missing genotypes that are not included on the low densit...

In 2008 a breeding program to increase production level in indigenous chickens was initiated at the Debre Zeit Agricultural Research Center in Ethiopia and is currently producing its 8th generation. Aim of this paper was to evaluate the success of the breeding program. Selection was on own perfor...

A simulation study was conducted to optimize a cooperative village-based sheep breeding scheme for Menz sheep of Ethiopia. Genetic gains and profits were estimated under nine levels of farmers' participation and three scenarios of controlled breeding achieved in the breeding programme, as well as...

Artificial selection towards a desired phenotype/trait has modified the genomes of livestock dramatically that generated breeds that greatly differ in morphology, production and environmental adaptation traits. Angus cattle are among the famous cattle breeds developed for superior beef quality. T...

Despite the wide range of observed phenotypic diversities and adaptation to different ecological conditions, little has been studied regarding the genetics of adaptation in the genome of indigenous cattle breeds of developing countries. Here, we investigated the linkage disequilibrium (LD) and id...

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...

he survey was carried out in Horro district of Horro Guduru zone, west part of Ethiopia. The objectives of the survey were: to describe cattle production system, trait preferences, breeding practices, and constraints in utilization of the breed and to use the information generated as baseline dat...
