I was wondering if there is a shot to give a mare before breeding that keeps her from aborting. She has had her 3-way shots already. Some of my mares are just not settling due to rainy cold weather. Also the 3-way does not have rhino in it.

There are so many causes of abortion or early embryonic death that it would be impossible to develop any sort of pre-breeding innoculation to prevent it.
There is a product undergoing final testing that if approved will become available to give to mares pre-breeding (a single injection) that will stimulate endogenous progesterone production, probably reducing the need to give a progestagen supplement such as Regumate, so stay tuned for that!
To prevent abortion due to Rhinopneumonitis you are correct in your observation that the 3-way innoculation does not cover your mare. You will have to use an immunisation specifically designed for it ("Pneumabort-K" and "Prodigy" are the two most commonly used in North America), and you will need to give it at 5, 7 and 9 months of pregnancy, and contemplate giving it at 3 months as well if your mare is in a high-risk situation for possible contact (busy boarding/showing barn etc.).

Jos, thank you for your help. Is Regumate something that I sould be looking at? Is it a single shot or what is it? I did have 2 mares that were ultrasound at 24 days last year and didn't deliver a foul.

It is my opinion that there is far too much unnecessary Regumate used... I would encourage you to have a complete pre-breeding work-up done which will include an endometrial swab with culture and cytology (if a cytology smear is not prepared in conjunction with the culture of the swab sample, then the results of the culture as far as showing pathogenic status of the uterus are WORTHLESS!!!! It is essential that if a "positive culture" result is seen that there be neutrophils also seen on the cytology smear - without those neutrophils present, it is most likely that the culture result is indicative of a contaminated sample! So - no cytology, no accuracy!) or possibly a biopsy.
Another frequent cause of early pregnancy loss is post-breeding endometritis, which can often be cleared by use of oxytocin in the manner described in the article that appears here on the web site.
By the way - I didn't comment earlier, but the cold rainy weather is not the cause for your mares not settling.... if that were the case there would never be another foal born in England!

Jos, thats interesting, Not only was I told about the weather,I was also told that because of the dry winter we have had that the well water is harder and that the mares could have got a urinary tract infection.and maybe I'm looking in the wrong place, Maybe it's my stud. I dont breed outside mares so I have never been to worried about infections. Nor do they ever leave home.
