From what I've read (but no practical experience), it works the same as Regumate but relieves you of daily administration... Also known as CIDR- controlled internal drug releasing device (I think these are more the sponges). It's progesterone vs progesten (Regumate)
Apparently it allows a quicker oestrus and ovulation post progesterone treatment because it allows natural development of the follicle to continue during treatment. Another advantage may be that the levels of systemic progesterone decline over time, as the hormone from the device is absorbed. Reported intervals of 2-3 days from end of treatment to oestrus and ovulation for PRID and CIDR vs reports of 8-10 days on Regumate. Downside is potential vaginitis.
Therefore, this treatment protocol appeared to offer a convenient, economical and reliable method for managing transitional mares
That's not the same as AHF is it? I wonder what the advantages/disadvantages over BET altrogenest might be (cost wise)? Possibly that you don't need to order a full bottle... but you'd need the vet to do the implant probably.
The intra-vaginal devices are used all the time in cattle. You can use them in mares, but they cause a really nasty vaginitis that most owners object to. It doesn't seem to cause long-term issues, but with the other products available it doesn't seem worth it.
