Marshall, KarenGibson, John P.Okeyo Mwai, AllyMwacharo, Joram M.Haile, AynalemGetachew, TesfayeMrode, Raphael A.Kemp, Stephen J.[Livestock genomics for developing countries―African examples in practice]Livestock genomics for developing countries―African examples in practice

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...

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

The polymorphism at the PvuII recognition site in the ESR gene showed no statistically significant association with sow productivity traits in a Meishan x Large White F2 population. Estimates of the effect on litter size were. however, in the opposite direction and statistically different from pr...

Body linear measurements, and specifically heart girth (HG), have been shown to be useful predictors of cattle liveweight. To test the accuracy of body linear measurements for predicting liveweight, crossbred dairy cattle of different genotypes were measured and weighed. A total of 352 mature cow...
