Abstract;This study was performed to investigate the relationship between percentages of cured cows and antimicrobial treatment of clinical coliform mastitis among dairy cows at 53 livestock clinics on Hokkaido, Japan. The percentage of cures varied from 66.24% to 92.70% and was negatively associated-with the frequency of systemic antimicrobial administration (r=-0.37,P<0.01), systemic fluoroquinolone administration (r=-0.28,P<0.05), and average number of intramammary injections of 150mg cefazolin (r=-0.45,P<0.01). It was positively associated with the average number of intramammary injections of penicillin-G-procaine (300,000U) + dihydro-streptomycin (300mg) (r=0.38,P<0.01). The notable difference in cures among livestock clinics may result from differences in antimicrobial administration. (author abst.)
