A uterine pessary containing penicillin, streptomycin, formosulphathiazole and ethinyloestradiol, was assessed for its efficacy in reducing the frequency and severity of uterine infections in cows after parturition. Fifteen pluriparous Holstein Friesian cows had pessaries inserted into the uterus within 24 hours after calving. Compared with 14 similar untreated cows there were significant reductions in the number infected by Actinomyces pyogenes and in the number exhibiting abnormal uterine discharges.
