Effects of the intra-uterine administration of Montanoa tomentosa extracts upon Postpartum Metritis in the dairy cow

Abstract

Montanoa tomentosa aqueous crude extract has been used for the last five centuries for the induction of labor, regulation of fertility, treatment of postpartum bleeding problems and to induce menses. In the present study, the hypothesis that the aqueous crude extract of M. tomentosa alleviates the metritis of dairy cows was tested. Adult Holstein Friesian dairy cows were diagnosed by gynaecological palpation as positive to postpartum metritis and single individual treatments of M. tomentosa or oxytetracycline were intra-uterine administered. Results showed that intrauterine administration of crude extracts of M. tomentosa alleviates the postpartum metritis without altering the ovarian activity. Present data reveal an emmenagogue action of the M. tomentosa extract in dairy cows that suffer postpartum metritis.
