Had lots of fun explaining to the gals at the border crossing what they were for lol. CIDR's are kind of the holy grail for an A.I. tech-I'm already booking breeding days in June which makes my time management alot easier. The thing with a CIDR program is that things have to be precise-accurate syringes-cleanliness-timeliness all have to be on the ball. I prefer not to haves ladies help with the injections just for safety reasons as they are reproductive drugs. We've been giving a shot of estradiol/progesterone at time of Cidr insertion then a shot of straight estradiol a day after we pull them.
