Tsetse-transmitted trypanosomosis poses severe constraints to livestock productivity in sub-Saharan Africa, affecting large areas of the continent that hold the greatest potential for agricultural development. Greater exploitation of the genetic resistance to trypanosomosis (trypananotolerance) t...

Direct and maternal (co)variance components and genetic parameters were estimated for growth and reproductive traits in the Kenya Boran cattle fitting univariate animal models. Data consisted of records on 4502 animals from 81 sires and 1010 dams collected between 1989 and 2004. The average numbe...

Bio-economic profit models were developed and applied to evaluate biological and economic variables that characterize production systems utilizing the Boran breed. Production systems were described according to their sale age (24 months short-fed or 36 months long-fed), levels of input (low, medi...

The predicted performance of nine crossbreeding strategies for milk production and reproductive traits and cow live weights (LW) were compared. The strategies were selected because of their superiority to many others. The data were from crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and S...

A total of 1443 records were used to estimate individual and maternal additive genetic breed and heterotic effects for preweaning growth and survival traits of crosses of Ayrshire (A), Brown Swiss (B), and Sahiwal (S) in a dairy herd in the lowland coastal tropics of Kenya. Individual and matern...

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...
