Hey guys. I've got a quick question (or maybe not). My mare is due for her pneumabort shot, but I am not sure if this is necessary. She had the shot at 3 and 5 months. At her 5 month ultrasound, the vet wasn't sure if she was 5 months or not. He said she could be further (After 2 years of unsuccessful AI we did a natural breeding this year leaving the two in a field for 1 month). Anyways, she has already started to bag because she normally goes early. Do you think a pneumabort shot is necessary or not? With gas prices like they are in our area ($4.25 a gallon for diesel), this one vet trip will be very costly for one shot. I am against shots from feed stores. Working at one, I know that sometimes the truck drives do not pay attention to try to keep them cool nor do all employees put the in a refrigerator after receiving them. I have known many animals to get sick even after being vaccinated with shots from feed stores. So that is not an option. Any comments on this?
