Genome‑wide insights of Ethiopian indigenous sheep populations reveal the population structure related to tail morphology and phylogeography
Background Ethiopian sheep living in diferent climatic zones and having contrasting morphologies are a most promising subject of molecular-genetic research. Elucidating their genetic diversity and genetic structure is ...
Evaluation of increased feed supply and different fattening strategies for an Ethiopian sheep population by system dynamics modelling
Context: The productivity of Ethiopian smallholder farms is considered to be low owing to different factors such as feed shortage, lack of breeding strategies, disease prevalence and missing marketing strategies.
Aim: The ...
Whole-genome resequencing of wild and domestic sheep identifies genes associated with morphological and agronomic traits
Understanding the genetic changes underlying phenotypic variation in sheep (Ovis aries) may facilitate our efforts towards further improvement. Here, we report the deep resequencing of 248 sheep including the wild ancestor ...
The maternal origin of indigenous domestic chicken from the Middle East, the north and the horn of Africa
Indigenous domestic chicken represents a major source of protein for agricultural communities around the world. In the Middle East and Africa, they are adapted to hot dry and semi-dry areas, in contrast to their wild ...
Clapping with Two Hands: Transforming Gender Relations and Zoonotic Disease Risks through Community Conversations in Rural Ethiopia
Gender inequalities and zoonoses are major concerns in livestock production systems worldwide. Livestock producers are at high risk of zoonotic diseases due to direct and indirect contact with their livestock and livestock ...
Coat color alterations over the years and their association with growth performances in the Menz sheep central nucleus and community-based breeding programs
In the traditional Menz sheep breeding, communities select against black coat color and therefore its frequency is declining over time. We hypothesize that this exercise is causing the loss of an important gene pool. Data ...
Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefits
Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised, government-controlled breeding schemes which have been implemented in many developing countries. An innovative ...
Contribution of small ruminants to food security for Ethiopian smallholder farmers
This study investigates how and to what extent arguments related to food security influence preference of livestock species for women and men. Data was collected in four regions of Ethiopia through 92 focus group
discussions ...
Historical Introgression from Wild Relatives Enhanced Climatic Adaptation and Resistance to Pneumonia in Sheep
How animals, particularly livestock, adapt to various climates and environments over short evolutionary time is of fundamental biological interest. Further, understanding the genetic mechanisms of adaptation in indigenous ...
Paternal Origins and Migratory Episodes of Domestic Sheep
The domestication and subsequent global dispersal of livestock are crucial events in human history, but the migratory episodes during the history of livestock remain poorly documented [1, 2, 3]. Here, we first developed a ...
