Rege, J.E.O.Muigai, Anne W.T.Chenyambuga, S.W.Kierstein, G.Hanotte, Olivier H.[Assessment of the genetic diversity in African small ruminants: Present status and future prospect]Assessment of the genetic diversity in African small ruminants: Present status and future prospect

Microsatellite loci are tandem repeats of short DNA sequences (1-5bp). Polymorphism in these loci results from variation in the number of repeat units. Microsatellites are numerous and dispersed among the chromosomes in all eukaryotic genomes. They are now the markers of choice for genome mapping...

Lebbie, S.H.B.Yapi-Gnoare, C.V.Rege, J.E.O.Baker, R.L.[Current developments in the management of small ruminant genetic resources: Sub-Saharan Africa]Current developments in the management of small ruminant genetic resources: Sub-Saharan Africa

Ethiopia has a large farm animal genetic diversity. The existence of this diversity is due in large part to its geographical location near the historical entry point of many livestock populations from Asia, its diverse topographic and climatic conditions, the huge livestock population size and th...


Ayalew, W.Getahun, E.Tibbo, MarkosMamo, Y.Rege, J.E.O.[Current state of knowledge on characterisation of farm animal genetic resources in Ethiopia]Current state of knowledge on characterisation of farm animal genetic resources in Ethiopia
Autor: Rege, J.E.O.

The concept of a breed, in which all members have a pedigree tracing their ancestry, was developed primarily in Western Europe during the eighteenth century. Today, in the developed world, breeds are recognized as distinct intra-specific groups, the members of which share particular characteristi...

A selection programme (PNSO) was set up in 1983 in Cote d'Ivoire to increase growth and liveweight of the indigenous Djallonke sheep, using open nucleus breeding system. Selection was based on male individual weight at 80, 180 and 365 days of age. This paper Reports results of analyses of 10,417 ...

Seven cattle populations indigenous to East Africa and three reference breeds (Sahiwal, N'Dama and Friesian) were characterized with 18 autosomal microsatellite loci. Within-breed diversity was high in all breeds with observed heterozygosities ranging from 0.511 (+ or -) 0.214 (N'Dama) to 0.660 (...

Sustainable livestock improvement cannot be guaranteed for most tropical areas of the world without utilization of the evolutionary adaptation of the indigenous livestock breeds. The paper summarizes the adaptive traits of indigenous tropical breeds, presents a case for their evaluation and discu...
