Genetic analysis of reproductive and productive performance of Friesian cattle in Kenya. II. Genetic and phenotypic trends
The Kenya Livestock Recording Centre progeny testing data base covering the period 1968 through 1987 was used to estimate genetic and phenotypic trends in Friesian cattle for milk yield of all lactations, first lactation milk yield, age at first calving, and calving interval. Annual genetic and phen...
