Reaction to P&E injections and 14-day check question

[EquusMagnificus]

I am following the P&E protocol with one of my mares. I have given her some of her injections in the pectoral muscles and she seriously swelled up! Is this a normal reaction or...? She had a stronger reaction to the progesterone shot... I am not really worried but I am still wondering how much normal this is...

As well, today was our first 14-day pregnancy check... and alas, we have our first "not in foal" diagnosis... Darn! Mare has a CL on her left ovary and no oedema. Any chance she might still be in foal? :winkgrin: :lol: She double ovulated and was given hCG at insemination. No oxytocin protocol followed, I had given birth the night before and could not be present for the insemination or further short term follow-up work... That'll teach me! :winkgrin: We're going to be rechecking her next Thursday to order semen again so I'll have my 100% confirmation of "not in foal" at that moment as well as we'll be at day 20.

When I use the P&E I see swelling more often than not. I usually give it in the pectoral muscles, as well, and sometimes the swelling is quite dramatic.

Thank you Hillside! My vet was just here and I forgot to mention it to her! I am glad to know it is more on the normal end of the scale then the opposite... Injections on her croup don't swell as much so I have been alternating injection sites... The swelling in the pectoral muscles is indeed quite dramatic! She looks like an equine body builder! :lol: But she isn't sore or affected in any other way... Thank goodness inspections are two months away!

When I was using P&E a lot, I always rotated the injection sites - pectorals, neck and hamstring. Be sure to inject down lower on the haunch (hamstring area) and not on the top of the croup, so that any problem can drain. I also used the smallest guage needle that would do the job.

One year the medium changed from cottonseed oil (if I remember right) to sesame seed oil. The sesame seed oil caused very nasty swellings.

If I am not mistaken, there is a newer one shot hormone that is very accurate (much better than the old one shot P&E). If I ever go back to timed inseminations, I'll try it to give my ladies an easier time.
