Data on Dajllonke sheep collected from 1983 through 1992 on 29 participating farms of an open nucleus improvement programme and from the nucleus were analysed. Initial on-farm records on 14342 lambs and on-station records on 2551 ram lambs were edited down to 6605 for birth weight (BWT), 5857 for...

The need for, potential benefits of, and possible problems with the establishment of a multi-country genetic evaluation scheme for Africa are discussed. The most compelling argument for such a scheme is the opportunity it may provide for the genetic improvement of indigenous livestock populations...

A selection programme was set up in 1983 in the Ivory Coast to improve the growth and live weight of the indigenous Djallonke sheep using an open nucleus breeding system. Selection was based on male individual weights at 80, 180 and 365 days of age. Multiple sires were used in farmers' flocks. In...
