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...

Crossbreeding data involving Ghana Shorthorn, Sokoto Gudali and their Jersey F1S and backcrosses collected over a 16-year period were analysed to estimate additive and heterotic effects for milk production, reproduction and calf growth traits. Sokoto Gudali was significantly better than Ghana Sho...
