Title: Converting multi-trait breeding objectives into operative selection indexes to ensure genetic gains in low-input sheep and goat breeding programmes
Author(s)Mueller, Joaquín; Getachew, Tesfaye; Rekik, Mourad; Rischkowsky, Barbara; Abate, Zelalem; Wondim, Bekahegn; Haile, AynalemDate: 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)Ahbara, Abugasim; Rekik, Emna; Abate, Zelalem; Goshme, Shenkute; Getachew, Tesfaye; Haile, Aynalem; Rischkowsky, Barbara; Mwacharo, JoramDate: 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 ... -
