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 ...
Community-Based Breeding Program is an attractive option for genetic improvement of small ruminants
In small ruminants, centralized breeding schemes, entirely managed and controlled by governments – with minimal, if any, participation by farmers – were developed and implemented in many developing countries. Such programs ...
System dynamics modeling in designing breeding schemes: The case of Menz sheep in Ethiopian highlands
A comprehensive dynamic simulation model was developed to describe a community-based breeding program for the Menz sheep population of Ethiopia. Selection of male and female animals based on their own and maternal performance ...
The African Goat Improvement Network: a scientific group empowering smallholder farmers
The African Goat Improvement Network (AGIN) is a collaborative group of scientists focused on genetic improvement of goats in small holder communities across the African continent. The group emerged from a series of workshops ...
Genome‑wide scans identify known and novel regions associated with prolifcacy and reproduction traits in a sub‑Saharan African indigenous sheep (Ovis aries)
Maximizing the number of ofspring born per female is a key functionality trait in commercial- and/or subsistence-oriented
livestock enterprises. Although the number of ofspring born is closely associated with female fertility ...
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 ...
Characterization of indigenous breeding strategies of the sheep farming communities of Ethiopia
This working paper synthesizes and analyzes the characteristics of the indigenous sheep production and breeding strategies and practices of four sheep farming communities located in pastoral (Amibara), sub-alpine sheep-barley ...
Optimization of selection for growth in Menz Sheep while minimizing inbreeding depression in fitness traits
The genetic trends in fitness (inbreeding, fertility and survival) of a closed nucleus flock of Menz sheep under
selection during ten years for increased body weight were investigated to evaluate the consequences of ...
Prospects for using nonconventional feeds in diets for Awassi dairy sheep in Syria
High feed costs are major obstacles for resource-poor dairy sheep farmers in West Asia, along with large fluctuation in grain and straw prices. Farmers need low-cost diets using locally available feeds that can provide ...
Guidelines for Setting up Community-based Sheep Breeding Programs in Ethiopia: Lessons and experiences for sheep breeding in low-input systems
These guidelines are designed for all those involved in planning and implementing sheep breeding activities with resource-poor farmers in developing countries. This includes research centers, non-governmental organizations ...
