Ray, we wrap our series on CIDR inserts. What’s the best way to discard after use?

The recommendation for discarding is that you would go ahead and put it in a plastic bag and discard it in the solid waste.

We have talked about, in the past I think, how to store these?

The CIDRs come wrapped in a Ziploc type of bag. There are ten per bag. They need to be kept cool and dry. You don’t want them to get warm, because they can just start. And you don’t want them to get moist, because the moisture will leak the progesterone out of the CIDR. They come ten in a bag, so if they are kept in the bag and are kept cool and dry, they should stay good for a while. There is expiration, but the expiration date is usually fairly long.

With the FDA clearance on this, obviously the research has been done. But have you noticed any side effects when using these inserts?

There is vaginitis that will develop, and most producers are not crazy about this vaginitis. It's irritating the lining of the vagina. But once the CIDR's removed, it takes about two days for cows to come into estrus, and those two days are enough for removal of that irritation, that she clears up on her own. Very few cows would have a persistent vaginitis. The big problem is not being sanitary putting them in. Of course, the vulva is directly below the rectum. Before we insert the CIDR, we need to clean the rear end of the animal up so that we do not insert any fecal material when we insert the CIDR.

A Select Sires Representative could help in training with that?

That’s correct. We have videos, we have laminated posters, and, again, we will be glad to help on the training of the individuals that would insert the CIDRs. CIDRs in the last few years have become very popular. I would say most producers have used them, maybe some a little bit more, some much more. But yes, a Select Sires specialist would be more than glad to help with that procedure.

And there is some question with the handling. Would the expiration date still apply if the package has been previously opened?

The expiration date is probably good for a year more, and so it really shouldn’t be a problem. What happens is that the silastic is impregnated with the progesterone, and so the progesterone comes to the surface. If it is really flaky, I would be cautious about using it. But if you dan’t have it where it flakes off in your hand, I would say it is probably not a problem.
