Ojango, Julie M.K.Oyieng, Edwin P.Audho, James O.Okeyo Mwai, Ally[Utilizing technology to improve market access and livelihood security among pastoralists in eastern Africa: A case for the indegenous sheep in Kenya]Utilizing technology to improve market access and livelihood security among pastoralists in eastern Africa: A case for the indegenous sheep in Kenya
Gizaw, SolomonGetachew, T.Lemma, S.Abebe, A.Goshme, S.Okeyo Mwai, AllyDessie, Tadelle[Genetic selection is a feasible and effective breeding strategy for indigenous sheep populations in Ethiopia]Genetic selection is a feasible and effective breeding strategy for indigenous sheep populations in Ethiopia

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...


Gizaw, SolomonArendonk, Johan A.M. vanValle-Zárate, A.Haile, AynalemRischkowsky, Barbara A.Dessie, TadelleOkeyo Mwai, Ally[Breeding programmes for smallholder sheep farming systems: II. Optimization of cooperative village breeding schemes]Breeding programmes for smallholder sheep farming systems: II. Optimization of cooperative village breeding schemes

Survival analysis applying proportional hazards models was used to investigate genetic and non-genetic factors affecting ewe longevity and lamb survival of sheep in Ethiopia. Data were obtained from an on-station closed nucleus breeding program of Menz sheep and an on-farm Awassi×Menz sheep cross...


Getachew, T.Gizaw, SolomonWurzinger, MariaHaile, AynalemRischkowsky, Barbara A.Okeyo Mwai, AllySölkner, J.Meszaros, G.[Survival analysis of genetic and non-genetic factors influencing ewe longevity and lamb survival of Ethiopian sheep breeds]Survival analysis of genetic and non-genetic factors influencing ewe longevity and lamb survival of Ethiopian sheep breeds

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

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. ...


Mirkena, T.Duguma, G.Willam, A.Wurzinger, MariaHaile, AynalemRischkowsky, Barbara A.Okeyo Mwai, AllyTibbo, MarkosSölkner, J.[Community-based alternative breeding plans for indigenous sheep breeds in four agro-ecological zones of Ethiopia]Community-based alternative breeding plans for indigenous sheep breeds in four agro-ecological zones of Ethiopia

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...
