Hi Jos, I manage a small TB farm. Out of 5 mares we've had 3 cases of placentitis. First mare started bagging up early, thickening of placenta was confirmed via ultrasound. Mare was treated. She red bagged but I got the foal out in time and all was well. 2nd mare red bagged as well. Placentitis was not confirmed prior to delivery but our vet thinks that the placenta looked suspicious. Plus she dripped milk of and on, starting 10 days prior to foaling. 3rd mare, premature udder developement led to ultrasound and revealed thickening. She's currently getting treated. SMZ, regumate, pentoxifylline, banamine. Any thoughts? Where would you start? Apparently there's no fescue in the hay. Test hay and grain?
I would have my doubts about there being even an undetected fescue (endophyte) issue, as you have mammary development in all mares, and with endophyte issues, one of the typical warning signs is lack of mammary development.
I would consider trying to isolate a pathogen to see if there is a common cause - leptospirosis comes to mind for example. You might want to send the placenta off to the path. lab. for evaluation with this last mare, especially if it appears abnormal upon foaling.
Don't know if there are or aren't documented cases, but there are a lot of deer, and I suspect Leptospirosis is present. Check with your vet.
