Douglas showed that placentitis mares treated with estrogen were significantly more likely to produce a live foal than affected mares that did not receive estrogen: 70% vs. 20% (n=20 and 50 respectively). Initially the fullness of the udder may appear to fluctuate during the day, but as parturition nears, the udder will remain distended and the teats, once flat, will start to swell and tip slightly outward as they fill with fluid.

"Waxing" is excretion of a small amount of colostrum from the teat, forming a yellowish, wax-like bead at the end of the teat. [20]It must however also be noted that other research has found that in mares with experimentally induced ascending placentitis Altrenogest treatment did not appear to make a difference in outcomes. [7]The most common mode of access is via the cervix, which has been in some way compromised, with the pathogen then ascending up through the uterus this form known as ascending placentitis accounts for over 90% of placentitis cases[8]. Premature udder development or running of milk may be linked to a placentitis or impending abortion.

J Reprod Fert Suppl 32, 59, 1982, 5Lu, K. (2013) The sub-fertile mare including causes and treatments in order to have a successful breeding season and a full term foal. Milk evaluation at 331 days of gestation, the day of foaling, shows 400 ppm calcium and a very slight drop to a pH level of 6.4. More recent research has shown that when the standard treatment of antibiotics, Flunixin meglumine and Altrenogest (Regumate) are used, estrogen levels are lower, and therefore recommends supplementation with Estradiol Cypionate, observing that inclusion of estradiol cypionate as part of the treatment for experimentally ascending placentitis appears to be more favorable than altrenogest.[15]. While the exact timeline of changes in mammary secretions is different for every mare, once fluid can be stripped from each teat, the changes in both color and secretion makeup will typically occur in a similar sequence. After the foal is born, the mare will continue to lie on her side for another 15 to 20 . There is a difficulty in identifying what is premature filling of the udder.
