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

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...

Gibson, John P.[A coherent model for use of molecular genetic information for genetic improvement in low and medium input systems. Abstract]A coherent model for use of molecular genetic information for genetic improvement in low and medium input systems. Abstract

About 30% of all farm animal breeds worldwide are at risk of extinction. To prevent this irreversible erosion of genetic diversity, the limited funds available for conservation need to be allocated in the most efficient way. Applying the diversity concept of Weitzman [Quart. J. Econ. CVII (1992) ...
