My mare was AIed with 30cc fresh cooled semen this morning at 11:00. Tonight at 7:00 she has a milky white vulvar discharge. Is this a sign of infection? Should I have her treated (flushed and given oxytocin) tomorrow? Or is it normal to have some discharge? Thanks for the input.

Anytime a mare is bred - and I do mean anytime, so include live cover, AI, fresh, cooled and frozen semen - she should mount a post-breeding inflammatory response. Think about it - how clean is the natural breeding process? Not very!!! :-) That post-breeding inflammatory response is there to assist in clearing uterine contaminants introduced during the breeding process. It starts to be present shortly after breeding, is actively present by 6 hours post-breeding (PB), peaks at about 16 hours PB in healthy mares, and is dissipated by about 24-30 hours PB in healthy mares. When I say "healthy mares" I meant mares that have a healthy uterine environment, as opposed to those with delayed uterine clearance. This latter group of mares are those that will generally benefit from the use of ecbolics such as oxytocin post-breeding.

As an interesting side-note: The effect that you mention - pus dripping from the vagina post-breeding - is not infrequently attributed to "a reaction to the extender" by the inexperienced. It is in fact the place you want that pus - out on the ground!!!

Thanks for the information. This mare was breed last year and conceived on the first try, carried the fetus until 7 1/2 months and then aborted. The placenta and foal were not found so it was difficult to establish a diagnosis. After reading some posts here I'm wondering if we should have done a culture/cytology and biopsy before breeding this year (Kleb?). She had a complete pre-breeding screen last year (ultrasound, culture/cytology) and everything was fine. Thanks again!

It is always sensible to do a culture and cytology at the very least in everything except a post-foaling mare (that will always show inflammation and contamination).
