Evaluates the growth performance of calves born to Boran cows and weaned at either six or eight months. Early weaned calves were further divided to either receive supplementary feed until eight months of age or serve as controls. There was no significant differences between Boran and crossbred ca...

Data collected on number of services per conception (NSC), age at first calving, (AFC), calving interval and calf pre-weaning mortality rate of Boran cattle and their Friesian crosses were evaluated. The NSC was 1.81, 1.61 and 1.69 for Boran, F1 Boran-Friesian and three-quarter Friesian heifers r...
