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...

Economic values for production and functional traits in the Boran cattle in Kenya
Ensuring that locally adopted breeds are a functional part of production systems is the most national and sustainable way to conserve animal genetic resources. This can only be possible if sustainable breeding strategies for such animals are developed which take into account their economically im...

African cattle genetic resources: Their unique attributes and conservation through utilization for milk production
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...

Estimates of crossbreeding parameters for defining optimal crossbreeding systems for the coastal lowland tropics
A total of 1443 records from a private ranch in the coastal lowland tropics of Kenya were used to estimate the comparative calf performance to weaning of the different crosses of Ayrshire (A), Brown Swiss (B) and Sahiwal (S). Individual and maternal additive and heterotic effects for, and heritab...
