Yellow Mucus on CIDRS

The mucus is a good sign.

The yellow smelly mucus is caused by the body of the deer rejecting the cidr.  Some will do this and some don't.  I always give Pen to the ones that have the yellow fluid at cidr pull.  Fact is the body will clean itself as soon as the cidrs are removed.  I suggest sucking up the yellow fluid when you cervicle AI the does to just get it out of your way when you do the AI.  I use a 60cc lamb tube feeder and just cut off the tip of the rubber tube, works great to suck up the fluid.  Most of the does will have cleaned themselves by the time you AI.

I would follow what jack has posted. This year I did a ton of girls, and as each one was AI'd we marked fluid/mucus levels and are going to see if it is a factor in conception. Just at a quick glance, I noted more of this in older previously AI'd girls over the first timers. Ryan

You can also use the speculum to remove any of that mucus when doing AI. I have found that the does who have large amounts of mucus when removing the CIDR almost always have some slightly off color mucus at AI time. In my experience, when a doe is at the peak of her ovulation (60hrs give or take) they frequently have a very distinguishable smell. I wouldn't say they stink, but they smell like a doe in heat! The does that have this smell usually have anywhere from 1-5 cc of a clear to slightly cloudy mucus inside their vagina. In my experience, the mucus had no correlation to the age of the deer.
