Hi My Friesian mare has a estrogen level in the 700s here progesterone was normal for her gestation. She had some edema on her belly and her leg (after eating 1/2 her mineral salt lick 5lb and drinking lots of water) Vet is rechecking levels, so we can put her on estrogen shots for a few days....would love to here from others who have had this problem. She is a 8yr maiden mare and this is my first foal. appreciate any advise. Thanks Brooke
Urgent...........please advise asap.... My mare now 320 days, has been on and off antibiotics and estrodiaol for the past few months pregnancy as possible placentitis was suspected. Although ultra sound was good, her blood tests lead us to belive there may be a problem. My current question is this. At 320 days she is on antibiotic treatment for a second 2 week period(Probenecid and Cipro) now day 4 of the 2 week period. She is also on 50ml of estrodiol once a day. My questions are is the estrodiol keeping her from foaling? I am wondering if the baby is now better in or out? her last blood results were on 8/6 - estrogen 437 and progesterone 40 the ones befor were on 7/30- estrogen 300 and progesteron 24, at wich time we uped her estrodiol from 30ml to the 50 ml. The past few day she is very baged up with sticky clear expreed from the utter. Back end a bit softer...and had a few drops of rust colored thin liquid from her vulva on close inspection. Very worried its my first foal and hers....need you advise.\ I want to do the right thing and I am scared that if the estrodiol is keeping her foaling I am doing the wrong thing? Please advise. Thanks Brooke
Rising progesterone levels do suggest approaching term, but can also be indicative of other issues that you have already suggested (placentitis). Decreasing estrogens also suggest term, but as you note, giving her estrogen may artificially elevate the level. You do indicate that milk is still clear, which does not suggest approaching parturition, and at 320 days, you would be on the early side of normal, although with placentitis it is not unusual to have an "early" delivery of a full-term foal.
I would suggest your veterinarian contacting Dr. Douglas of BET Pharmacy as he has done a lot of research into estrogens during pregnancy, and will be likely to be able to give a definitive answer, or at least a good range of possibilities.
