Title: Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefits
Author(s)Date: 2020-07-01Type: Journal ArticleStatus: Open accessCommunity-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 ... -
Title: Community-based sheep breeding programs in Ethiopia generated substantial genetic gains and socio-economic benefits
Author(s)Date: 2019-03-14Type: Journal ArticleStatus: Limited accessIn small ruminants, Community-based breeding programs (CBBPs) have been suggested as an alternative to centralized government-controlled breeding schemes which were implemented in many developing countries. An innovative ... -
Title: Converting multi-trait breeding objectives into operative selection indexes to ensure genetic gains in low-input sheep and goat breeding programmes
Author(s)Date: 2021-05-23Type: Journal ArticleStatus: Open accessSmall 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 ... -
Title: Effects of 10 years of selection in community-based breeding programs (CBBPs) on the genomes of Ethiopian indigenous sheep
Author(s)Date: 2021-11-21Type: Journal ArticleStatus: Timeless limited accessThe genomics revolution has made it possible to investigate genome dynamics arising from natural and artificial phenomena. Community-based breeding programs (CBBPs) have been advocated as the go-to strategy for genetic ... -
Title: Estimates of genetic parameters and trends for reproduction traits in Bonga sheep, Ethiopia
Author(s)Date: 2020-11-24Type: Journal ArticleStatus: Timeless limited accessInvestigation was carried out to assess the effects of environmental factors and to estimate genetic parameters and trends for reproductive traits in Bonga sheep, Ethiopia. Animals used in this study were managed by two ... -
Title: Estimation of (co)variance components, genetic parameters, and genetic trends of growth traits in community-based breeding programs of Bonga sheep
Author(s)Date: 2021-05-01Type: Journal ArticleStatus: Open accessCommunity-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 ... -
Title: Increased number of large non-atretic follicles and codominance effects account for high litter sizes in Bonga sheep
Author(s)Date: 2020-05-27Type: Journal ArticleStatus: Timeless limited accessTo understand the ovarian basis for prolificacy of Bonga sheep, a total of 31 ewes were selected based on litter size (LS) records and divided into two groups: High Prolificacy (HP) (n = 20) with LS ≥ 2 and Low Prolificacy ... -

Title: Three easy fixes for sire use can enhance genetic progress in community-based breeding programmes
Author(s)Date: 2021-11-01Type: Journal ArticleStatus: Timeless limited accessWe analysed options to optimize the use of sires in sheep and goat community-based breeding programmes (CBBP) for three scenarios occurring under field conditions: premature sale of selection candidates, fixed service ...
