Estimation of (co)variance components, genetic parameters, and genetic trends of growth traits in community-based breeding programs of Bonga sheep
Community-based sheep breeding programs (CBBPs) have been adopted strategically to improve Bonga
sheep, the most popular sheep breed in Ethiopia. The present study was undertaken to estimate genetic
parameters and genetic ...
Converting multi-trait breeding objectives into operative selection indexes to ensure genetic gains in low-input sheep and goat breeding programmes
Small ruminant breeding programmes in low-input production systems are best organised at the community level. Participant farmers have to agree on goal traits and their relative importance. When BLUP breeding values of ...
Field synchronization of Ethiopian Highland sheep for fixed time artificial insemination: improvement of conception rate with a double injection of prostaglandin at 11 days
The study investigated, for fixed time artificially inseminated (AI) Menz ewes in field trials, the reproductive
performance of prostaglandin-based treatments simultaneously to the standard ‘P4+eCG’ protocol. A total
of ...
Participatory identification of breeding objective traits and selection criteria for indigenous goat of the pastoral communities in Ethiopia
Structured questionnaire, own-flock rankings and group discussions were undertaken to assess goat breeding practices and to identify traits of interest for genetic improvement of pastoral goats. Four pastoral villages in ...
Risk Factors for Reproductive Disorders and Major Infectious Causes of Abortion in Sheep in the Highlands of Ethiopia
Community-based sheep breeding programs (CBBPs) were established in Ethiopia since 2010. Improved rams from CBBPs need to be disseminated. However, there is a risk of transmitting reproductive diseases to other community ...
Effect of processed sweet lupin (Lupinus angustifolius) grain supplementation on growth performance and socioeconomic feasibility of Doyogena sheep in Ethiopia
Background
The experiment evaluated the effect of supplementing sheep fed natural pasture hay with processed sweet lupin grain on growth performance and its economic feasibility. The finding revealed that use of steamed ...
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 ...
Estimates of genetic parameters and genetic trends for growth, reproduction, milk production and milk composition traits of Awassi sheep
Genetic parameters and genetic trends for growth, reproduction, milk production and composition traits were estimated for Syrian (S) and Turkish (T) Awassi sheep and their crosses maintained at the International Center for ...
Barley Straw Use for Animal Feed and Soil Mulch in Ethiopian Highlands Mixed Crop-Livestock Systems
Barley straw serves as livestock feed and mulch for soil and water conservation in the mixed barley-livestock systems of the Ethiopian highlands. High demand for barley straw biomass in the system creates competition between ...
Welfare Impact of Community-Based Veterinary and Breeding Services on Small Ruminant Keepers
Improved breeding practices and participatory health services have been designed and implemented by a partnership between national and international institutions in various parts of Ethiopia since 2014. Based on a panel ...
