What I WANT to do is ivermectin again on April 1 to make sure everything is under control. The broodmare is due around April 15. Is it okay to give her ivermectin 2 weeks prior to foaling?
It would be okay, but since you are supposed to give a dose of ivermectin right after foaling, there might not be any advantage to doing 2 doses so close together.
This topic attracted me because I am in a quandry with wanting to administer praziquantel for tapes (the extra ingredient that makes the ivermectin products "max" or "gold") but it is not labelled for use in pregnant or lactating mares. I know that doesn't mean it has been proven to be harmful, but I am cautious when a baby is involved. What do people do for broodmares who are essentially either pregnant or lactating or both all year around?
it's not the edge of the earth, but you can see it from here
Schiffon, a double dose (by wt) of Strongid is the tested and approved dewormer for pg mares.
Although, yes, Equimax is tested on pg mares too.
I would not use Zimec Gold (search the Horse Care forum for why) and prefer the dd. strongid, just because I've used it for years with no issues during pg.
I personally do not use chemicals of any type first 90 and last 90. I do not subscribe to the Ivermec 24hrs post foaling either, and a recent study done by The Horse indicated the practice may lead to ivermectin resistance. I don't have scours either.
I think the panacur power pack is safe for prego mares and will get tapes. I'm not sure if strongid does or not. Best thing would be to ask your vet. Ivermectin gold and quest make me nervous - have seen and heard of lots of bad side affects. Happy foaling
