A survey on mastitis in milking cows at Alemaya University dairy farm was conducted from January 1993 to December 1998. Randomly selected mastitis infected milk were subjected for bacteriological examination revealed that the major causative organisms were Staphlococcus spp, 42.5%, Escherichia coli, 32.9%, and Sreptococcus spp. 24.6%. The overall incidence of clinical mastitis averaged around 34 cases \\ 100 cows per year. Mean monthly mastitis cows over the study period were 3. There is an influence of age of cows on the incidence of mastitis and high yielding crossbred (15.20 kgs of milk / milking) appear to be equally sensitive to mastitis as the pure Holsteins (producing 20-25 kgs of milk / milking).
