Gizaw, SolomonHaile, AynalemDessie, Tadelle[Breeding objectives and breeding plans for Washera sheep under subsistence and market-oriented production systems]Breeding objectives and breeding plans for Washera sheep under subsistence and market-oriented production systems

Designing breeding schemes suitable for smallholder livestock production systems in developing regions has hitherto been a challenge. The suggested schemes either do not address farmers’ breeding goals (centralized station-based nucleus schemes) or yield slow genetic progress (village-based schem...


Gizaw, SolomonGetachew, T.Tibbo, MarkosHaile, AynalemDessie, Tadelle[Congruence between selection on breeding values and farmers’ selection criteria in sheep breeding under conventional nucleus breeding schemes]Congruence between selection on breeding values and farmers’ selection criteria in sheep breeding under conventional nucleus breeding schemes

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...

Optimization of cooperative village breeding schemes]Breeding programmes for smallholder sheep farming systems: II. Optimization of cooperative village breeding schemes

Pedigree recording and genetic selection in village flocks of smallholder farmers have been deemed infeasible by researchers and development workers. This is mainly due to the difficulty of sire identification under uncontrolled village breeding practices. A cooperative village sheep-breeding sch...

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...

Evaluation of alternative designs of breeding schemes]Breeding programs for smallholder sheep farming systems: I. Evaluation of alternative designs of breeding schemes

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...
