Kahi, A.K.Thorpe, W.R.Baker, L.[Estimates of heritabilities and genetic and phenotypic correlations for preweaning traits of calves in a crossbred dairy herd in coastal lowland Kenya]Estimates of heritabilities and genetic and phenotypic correlations for preweaning traits of calves in a crossbred dairy herd in coastal lowland Kenya

Crossbreeding parameters for milk production and reproductive traits and for cow live weight (LW) of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle were estimated using data from a dairy herd in the lowland coastal tropics of Kenya. An individual animal model was fi...


Kahi, A.K.Thorpe, W.R.Nitter, G.Baker, R.L.[Crossbreeding for dairy production in the lowland tropics of Kenya. I. Estimation of individual crossbreeding effects on milk production and reproductive traits and on cow live weight]Crossbreeding for dairy production in the lowland tropics of Kenya. I. Estimation of individual crossbreeding effects on milk production and reproductive traits and on cow live weight

An individual animal model was fitted to data from a crossbred herd in the lowland coastal tropics of Kenya to estimated breed cross means for a total of 25 genotypes having different proportions of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) genes. These means were then regressed...
