Genetic and environmental effects on age at first calving and calving interval of naturally bred Boran(zebu) cows in Ethiopia
Factors affecting reproductive performance in Boran cattle were investigated. Twenty-four years of data from a Boran cattle breeding and improvement ranch in the Rift Valley of Ethiopia were analysed to examine genetic and environmental influence on age at first calving (AFC) and calving interval (C...
