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 ...
Strengthen sheep and goat community-based breeding programs in Ethiopia towards scaling
Sheep and goat community-based breeding programs (CBBPs) has been implemented in Ethiopia since 2009. Initiated by the ILRI-ICARDA-BOKU, the programs are currently overseen by the International Research Center for Agricultural ...
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 ...
Increased number of large non-atretic follicles and codominance effects account for high litter sizes in Bonga sheep
To 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 ...
Optimization of community-based breeding programs
Any breeding program undergoes numerous stages of improvement and adjustment and is never completely flawless from the beginning. Initial selection in the community-based breeding programs (CBBPs) were made only based on ...
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 ...
Estimates of genetic parameters and trends for reproduction traits in Bonga sheep, Ethiopia
Investigation 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 ...
Effects of 10 years of selection in community-based breeding programs (CBBPs) on the genomes of Ethiopian indigenous sheep
The 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 ...
Increased number of large non‐atretic follicles and co‐dominance effects account for high litter sizes in Bonga sheep
To 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 ...
Genomic analysis of 10 years of artificial selection in community-based breeding programs in two Ethiopian indigenous sheep breeds
In recent times, community-based breeding programs (CBBPs) have been advocated as the best strategy for genetic improvement of local breeds in smallholder farms in developing countries. Since ...
