Should intrauterine tables/pessaries be used in cows with retained placenta?
In general before applying such a treatment we have to be very clear what the purpose of the therapy is: treatment of metritis or prevention. The second consideration is time after calving and condition of the cervical canal. At more than 12h post calving the cervical canal starts closing and such products can be administer only if a hand can be passed through the cervix comfortably.
