Abstract:
This study was conducted with the objective to evaluate and compare the lactation milk yield and reproductive performances of pure local and crossbred cows at Bako Agricultural Research Center, West Shoa Zone. The data used in this study include age at first service, age at first calving, number of service per conception, days open, calving interval and lactation milk yield of Pure Horro, Horro-Friesian and Horro-Jersey dairy cows at the research center. The independent variables examined were breeds and season. Least squares means were analysed using GLM (General Linear Model) procedure of SAS, 2016 (Version 9.4) with probability level of (Pcant difference (pto pure Horro and Horro-Frisian while no significant difference was observed between Horro-Frisian and pure Horro. The overall mean value of lactation milk yield was 1351.71 kg for which the three breed-groups studied showed significant difference (p
