Mwacharo, Joram M.Eui-Soo KimElbeltagy, Ahmed R.A.E.Aboul-Naga, A.M.Rischkowsky, Barbara A.Rothschild, Max F.[Genomic footprints of dryland stress adaptation in Egyptian fat-tail sheep and their divergence from East African and western Asia cohorts]Genomic footprints of dryland stress adaptation in Egyptian fat-tail sheep and their divergence from East African and western Asia cohorts

Haile, AynalemWurzinger, MariaMueller, J.Mirkena, T.Duguma, G.Rekik, MouradMwacharo, Joram M.Okeyo Mwai, AllySölkner, J.Rischkowsky, Barbara A.[Guidelines for setting up community-based small ruminants breeding programs: Second edition]Guidelines for setting up community-based small ruminants breeding programs: Second edition

In this study we genotyped 14 microsatellites to assess genetic diversity, population stratification and demographic dynamics using Egyptian local goats (Zaraibi, Baladi, Saidi and Barki) and the Shami (Damascus) goat from the Middle East and West Asia close to the geographic center of goat domes...


Elbeltagy, A.R.Aboul-Naga, A.M.Hassen, H.Solouma, G.M.Rischkowsky, Barbara A.Wacharo, J.M.[Genetic diversity and structure of goats within an early livestock dispersal area in Eastern North Africa]Genetic diversity and structure of goats within an early livestock dispersal area in Eastern North Africa

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

Breeding programmes described as community-based (CBBP) typically relate to low-input systems with farmers having a common interest to improve and share their genetic resources. CBBPs are more frequent with keepers of small ruminants, in particular smallholders of local breeds, than with cattle, ...


Mueller, J.P.Rischkowsky, Barbara A.Haile, AynalemPhilipsson, J.Okeyo Mwai, AllyBesbes, B.Valle-Zárate, A.Tibbo, MarkosMirkena, T.Duguma, G.Sölkner, J.Wurzinger, Maria[Community based livestock breeding programmes: Essentials and examples]Community based livestock breeding programmes: Essentials and examples

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
