The feasibility of using low-density marker panels for genotype imputation and genomic prediction of crossbred dairy cattle of East Africa

Autor: Aliloo, H. Mrode, Raphael A. Okeyo Mwai, Ally Ni, G. Goddard, M.E. Gibson, John P.

Cost-effective high-density (HD) genotypes of livestock species can be obtained by genotyping a proportion of the population using a HD panel and the remainder using a cheaper low-density panel, and then imputing the missing genotypes that are not directly assayed in the low-density panel. The ef...

Genetic tests for estimating dairy breed proportion and parentage assignment in East African crossbred cattle

Autor: Strucken, E.M. Al-Mamun, H.A. Esquivelzeta-Rabell, C. Gondro, C. Okeyo Mwai, Ally Gibson, John P.

Background:Smallholder dairy farming in much of the developing world is based on the use of crossbred cows that combine local adaptation traits of indigenous breeds with high milk yield potential of exotic dairy breeds. Pedigree recording is rare in such systems which means that it is impossible ...

Use of SNP genotyping to determine pedigree and breed composition of dairy cattle in Kenya

Autor: Gorbach, D.M. Makgahlela, M.L. Reecy, J.M. Kemp, Stephen J. Baltenweck, Isabelle Ouma, R. Okeyo Mwai, Ally Marshall, Karen Murdoch, B. Moore, S. Rothschild, Max F.

High levels of inbreeding in East African dairy cattle are a potential concern because of use of a limited range of imported germplasm coupled with strong selection, especially by disease, and sparse performance recording. To address this, genetic relationships and breed composition in an admixed...

Developmental challenges and opportunities in the goat industry: the Kenyan experience

Autor: Ahuya, C.O. Okeyo Mwai, Ally Mwangi-Njuru, D. Peacock, C.P.

Dairy goat development in Kenya started in the mid 1950s, with the introduction of exotic dairy goat breeds. Major projects to improve the dairy goat sector were not realized until the late 1970s under United Nations Development Programmes (UNDP) funded and FAO executed projects, which lasted unt...

Dairy production systems and the adoption of genetic and breeding technologies in Tanzania, Kenya, India and Nicaragua

Autor: Ojango, Julie M.K. Wasike, C.B. Enahoro, Dolapo K. Okeyo Mwai, Ally

Development of the livestock industry and its role in poverty alleviation in developing countries depends on how adaptive the production systems are to changing global environmental and economic trends. This paper characterizes dairy production systems in India, Tanzania, Kenya and Nicaragua, and...
