Jembere, TemergenHaile, AynalemDessie, TadelleKebede, KefelegnOkeyo Mwai, AllyRischkowsky, Barbara A.[Productivity benchmarks for community-based genetic improvement of Abergelle, Central Highland and Woyto-Guji indigenous goat breeds in Ethiopia]Productivity benchmarks for community-based genetic improvement of Abergelle, Central Highland and Woyto-Guji indigenous goat breeds in Ethiopia

Background Understanding the relationship between genetic admixture and performances is crucial for the success of crossbreeding programs. Use of small sets of ancestry informative markers (AIMs) is a cost effective option to estimate the levels of admixture in situations where pedigree recording...


Getachew, T.Huson, H.J.Wurzinger, MariaBurgstaller, J.Gizaw, SolomonHaile, AynalemRischkowsky, Barbara A.Brem, G.Boison, S.A.Mészáros, G.Okeyo Mwai, AllySölkner, J.[Identifying highly informative genetic markers for quantification of ancestry proportions in crossbred sheep populations: Implications for choosing optimum levels of admixture]Identifying highly informative genetic markers for quantification of ancestry proportions in crossbred sheep populations: Implications for choosing optimum levels of admixture

The objective of this review paper is to examine whether or not sheep crossbreeding is a feasible option to improve indigenous sheep breeds in developing countries using Ethiopian case as example. The paper reviewed and discussed the history of exotic breed introduction, research, and development...


Getachew, T.Haile, AynalemWurzinger, MariaRischkowsky, Barbara A.Gizaw, SolomonAbebe, A.Sölkner, J.[Review of sheep crossbreeding based on exotic sires and among indigenous breeds in the tropics: An Ethiopian perspective]Review of sheep crossbreeding based on exotic sires and among indigenous breeds in the tropics: An Ethiopian perspective

There are distinct breeds suitable for diverse purposes in the different production environments or ecological zones. Farmers in different production systems have different trait preferences and the strategies followed by them are also as diverse as the agro-environments within which they operate...


Duguma, G.Mirkena, T.Haile, AynalemIñiguez, L.Okeyo Mwai, AllyTibbo, MarkosRischkowsky, Barbara A.Sölkner, J.Wurzinger, Maria[Participatory approaches to investigate breeding objectives of livestock keepers]Participatory approaches to investigate breeding objectives of livestock keepers

System dynamics modelling approach has been widely used in the agriculture sector to describe livestock production systems, livestock health and natural resource management. However, its application in modelling livestock breeding programs and systems is limited. Therefore, this study explores th...


Tadel, K.Wurzinger, MariaGizaw, SolomonHaile, AynalemRischkowsky, Barbara A.Sölkner, J.[The use of system dynamics modelling methodologies in sheep breeding programs and management systems]The use of system dynamics modelling methodologies in sheep breeding programs and management systems

Haile, AynalemDessie, TadelleRischkowsky, Barbara A.[Performance of indigenous sheep breeds managed under community-based breeding programs in the highlands of Ethiopia: Preliminary results]Performance of indigenous sheep breeds managed under community-based breeding programs in the highlands of Ethiopia: Preliminary results

A breeding program to improve income from Raeini cashmere herds run by nomads in Southern Iran was implemented. Eight nomads agreed on improving fleece weight, body weight and down yield while reducing cashmere fibre diameter of white coated goats. Economic weights were calculated to define a bre...


Mueller, J.P.Ansari-Renani, H.R.Momen, S.M.S.Ehsani, M.Alipour, O.Rischkowsky, Barbara A.[Implementation of a cashmere goat breeding program amongst nomads in Southern Iran]Implementation of a cashmere goat breeding program amongst nomads in Southern Iran

Human exchange networks are instrumental in influencing gene flow among domesticates. Here, we investigated levels of within- and between-population genetic diversity in 289 animals from six indigenous sheep populations in Egypt (Barki, Farafra, Ossimi, Rahmani, Saidi, Souhagi) and 119 individual...
