To determine the protection factors for mastitis, questionnaires were applied to determine the control measures carry out for prevention and management of the bovine mastitis in 15 farms, managed under a double purpose system in the municipality of Monteria (Colombia). The diagnosis of the bovine mastitis was established by the CMT, RCS and bacteriological cultures (isolation). Variables were crossed with the results of the different diagnosis test using contingency charts. To determine the association, a Chi-square test and the Odds Ratio (OR) with their respective confidence interval (95%) were calculated. As general protection factors the direct administration by the owners and a permanency higher than 50% of the time was found. During milking, the division of work by the milkers regarding the milking procedure, the support of the calf, the implementation of sanity of nipples, when drying of nipples was acceptable, nipple sealing and the suckling of the calves at the end of milking were positive. The culling of cows with mastitis during the last year, the application of the dry cow therapy, the disinfection of the tip of nipples previous the dry cow therapy and the written delivery of sanitary recommendations were identified as protection factors in the aspects of practices of prevention.
