Genetic analysis of reproductive and productive performance of Friesian cattle in Kenya. I. Genetic and phenotypic parameters
An original data set of 31, 661 lactation records of Kenyan Friesian cows covering the period 1968 through 1987 was used to develop part-lactation extension factors for milk yield, and to estimate genetic parameters for production and reproductive traits. Effects of herds and year were significant f...
