Lukuyu, Margaret N.Gibson, John P.Savage, D.B.Rao, E.J.O.Ndiwa, Nicholas N.Duncan, Alan J.[Farmers’ perceptions of dairy cattle breeds, breeding and feeding strategies: A case of smallholder dairy farmers in western Kenya]Farmers’ perceptions of dairy cattle breeds, breeding and feeding strategies: A case of smallholder dairy farmers in western Kenya

Nimbkar, C.Gibson, John P.Okeyo Mwai, AllyBoettcher, P.J.Sölkner, J.[Sustainable use and genetic improvement]Sustainable use and genetic improvement

We present use of SNP technologies to obtain for the first time, rapid, large-scale, in situ estimates of performance of crossbred cows in smallholder herds. Compared to historical approaches, our approach allowed optimum crossbreed choices to be determined more rapidly and without question about...

Gebrehiwot, N.Z.Strucken, E.M.Aliloo, H.Marshall, KarenGibson, John P.[Genetic structure and differentiation among African Bos Taurus cattle breeds]Genetic structure and differentiation among African Bos Taurus cattle breeds

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...


Aliloo, H.Mrode, Raphael A.Okeyo Mwai, AllyNi, G.Goddard, M.E.Gibson, John P.[The feasibility of using low-density marker panels for genotype imputation and genomic prediction of crossbred dairy cattle of East Africa]The feasibility of using low-density marker panels for genotype imputation and genomic prediction of crossbred dairy cattle of East Africa

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 ...


Strucken, E.M.Al-Mamun, H.A.Esquivelzeta-Rabell, C.Gondro, C.Okeyo Mwai, AllyGibson, John P.[Genetic tests for estimating dairy breed proportion and parentage assignment in East African crossbred cattle]Genetic tests for estimating dairy breed proportion and parentage assignment in East African crossbred cattle

Gastrointestinal (GI) parasitic infection is the main health constraint for small ruminant production, causing loss of weight and/or death. Red Maasai sheep have adapted to a tropical environment where extreme parasite exposure is a constant, especially with highly pathogenic Haemonchus contortus...


Benavides, M.V.Sonstegard, T.S.Kemp, Stephen J.Mugambi, J.M.M.Gibson, John P.Baker, R.L.Hanotte, Olivier H.Marshall, KarenTassell, C. van[Identification of novel loci associated with gastrointestinal parasite resistance in a red Maasai x Dorper backcross population]Identification of novel loci associated with gastrointestinal parasite resistance in a red Maasai x Dorper backcross population

To evaluate the Weitzman approach for assessing alternative conservation strategies for breed ( population ) diversity, we used genetic distance measures between 49 African cattle breeds divided into two groups of 26 taurine ( Bos taurus ) and sanga ( Bos taurus×Bos indicus ) breeds and 23 zebu ...
