It's tax time almost, so I've been digging in drawers and files. Thumbing through my production records I have noticed I have a few cows that go a little long between calves. When calves are high I'm like why sell a cow that goes 14 months. Atleast she does go. I know many will question that thought process, so lets not debate it. My question is has anyone had any luck inserting a CIDR in a slow breeder that you intended to just live cover. I learned to ai years ago. Evidently before that technology existed. I still ai a sprinkling, using observed heat. I never developed a taste for syncing. I see everybody explaining there protocol for ai, and wondered if the CIDR had a practical application for a guy like me.

Lute nor the cidir will make a cow cycle. Lute will clear cyst.

A cidr will do more for you than lut or gnrh will as progesterone post calving is usually a limiting factor and both gnrh and lut only work on what the cow is providing. Gnrh plus a cidr is a pretty good jumpstart. A protien tub will likely cure more cows than all of the above put together.

Thanks, It seemed plausible to me. I just hate to sell a young cow that weans a big calf. If you have 5 that go long it's like losing 1 calf, or atleast that's the way I look at it. It seems the same few that cycle late everytime. If they get far enough behind, I just move them to fall herd. I keep blocks out when I'm feeding hay. I have always pulled them with the green up.
GNRH clears cysts not lute, lute will make a cow cycle and is the cheapest way if your just trying to get them to cycle a full sync is about 15 dollars a shot of lute is about 2 dollars if they dont respond with the first shot give them another in 10 days it will usually work. and maybe im not understanding what your trying to do but if your trying to get them to cycle lute is the cheapest way. If you think they could be cystic give them GNRH and 7 days later lute.C P is right they do need to be in pretty good shape it helps alot. all this is just my opinion so it and $1.25 will buy a cup of coffee

Lute won't work unless the cow has a functioning cl. The reason cidrs work so well is because they give the cow artificial progesterone so that she can form a cl for the lut to work on.
Exactly!! Bigfoot isn't asking how to make a cow that is cycling come into heat sooner. From what he posted, he has cows that are NOT cycling back soon enough to keep a 12 month cycle. Lut & GNRH will do nothing if cow isn't already cycling. CIDR will, in most cases, "jumpstart" her system - if she is in good BCS, has been at least 45 days, & did not have difficulty calving.cow pollinater":16bd6bc2 said:

Thanks for helping me understand the way it works even better. Even if it wasn't my post

2 choices for a slow breeder --- the stockyard or..............
get her in the chute give her a 2ml dose of Cystorelin insert a cidr
7th day pull the CIDR / 5ml dose of Lutalyse for a cow under 1350 and 6 ml for cows over 1350 lbs --breed 12 hours past observed standing heat
If you dont want to wait 12 hours past standing heat -- get he in the chute say 1 hour into standing heat give her another round of cystorelin then breed her about 3 hours later.
If she doesnt breed load her

Isn't a 2ml dose? That would be $2 a dose. I use estrumate instead, it is a 2 ml dose.....TexasBred":2s2aplma said:

Jeanne and others are right. Nothing will make a cow that is NOT cycling, come into heat. All lute, cidrs, feed, etc. does is make them cycle together. Rather than try to make one start cycling with drugs, explore why they are not cycling now. Look at feed and BCS first. Then maybe start looking at genetics and go on from there. gs
