[Treatment of mastitis in dry cows: treatment of all cows vs treatment of infected cows only (author's transl)].
Within a herd, three groups have been randomly constituted. --


METHODS
No dry cow therapy. -- Total Treatment group: all cows were submitted to dry cow therapy, in their four quarters. -- Limited Treatment group: cows were submitted to dry cow therapy in their four quarters, only if at least one quarter had given a CMT larger than or equal to +++, in the month before drying-off. --The cows were treated either with cloxacillin or with penicillin-streptomycin in 3% monostearate. The number of cows and quarters examinated and treated are given in table 1; the results of treatments are indicated in table 2. No significant differences can be found between Total and Limited Treatment groups; a slight improvement was observed when compared to CONTROL GROUP. Cloxacillin and penicillin-steptomycin gave similar results. The pathogenic and practical signification of these results is discussed.
