Resumo: Bovine Mastitis is a disease that causes high damage to milk production. Phytotherapy is the basis of Tagetes minuta L. can be used for disease control agroecological production units. The study aimed to evaluate application of antiseptics from medicinal plant from the postmilking teat disinfection. The treatments consisted of commercial iodine with treatment 1, used as teat pos-dipping on the right side, and hydro alcoholic extract from leaves of Tagetes minuta and macerated seeds Linum usitatissimum L., both at 10%, used on teats left as pos-dipping, cows in a commercial production unit that had, in average of 60 milking animals during the experiment that lasted 12 weeks. The prevalence of subclinical mastitis was evaluated using the CMT test once a week. Test mug of dark background was done at all milking. Sample of milk from all quarters was collected weekly for the isolation and characterization of present microorganisms . The incidence of new intramammary infections was calculated using the number of infection-free days by quarters, counted by weekly analysis of milk from all quarters in blood agar culture, as the denominator and the number of new cases as the numerator, defined as culture positive by Staphylococcus spp. or Streptococcus spp. in Sampling of milk per room. The index was corrected to 1000 / 4 days. Exclusion criteria: infection with Streptococcus spp or Staphylococcus spp in early labor and up to two weeks after a collection microbiologically positive. Animals with two successive collections negative after a positive were considered cured and reintroduced in the counting of days without infection. The chi-square test was used to compare the frequency of events between treatments. The CMT's weekly prevalence ranged in group 1 between 29.5% and 17.1%, and group 2 from 29.7% to 19.6%, not significantly different in any of weeks. The incidence of positive cultures for Staphylococcus / Streptococcus was 3.93 and 6.96 / 1000 / 4 / day for Groups 1 and 2 respectively, p = 0.057. There were four cases of mastitis clinic during the experiment, two in each treatment. We concluded the use of plant extracts for the disinfection of teats pos-dipping can be useful systems for milk production agro ecological.
