Got some cows I want to push forward a month in their calving. Typically I would Gnrh and CIDR them at 30 days post calving to jump start cycling then AI. Wondering if it would be just as easy and maybe more reliable running that little group with the herd bull this season. Thoughts? Maybe I should still give them a shot of Gnrh?

I agree with Dun; you will have more success if you induce heat and have a natural service ,rather than induce and AI. Sometimes it is hard to move them up with AI.

what dun said x3.
I would wait 30 days or so. We did that years ago and moved most of the cows up like we wanted. Some were more then 30 days because we wanted them calving closer together. We figured the desired calving date then the appropriate breeding date then gave the shots 2 weeks before that.angus9259":pt7vs1sp said:

If they're registered Angus, I'd synch them, AI once and turn them out with the bull immediately. You might need to DNA test the calves to be sure, but we both know an AI-sired Angus is more valuable than one out of your clean up bull. The little extra work might be worth it when you go to sell the calves.

I would like to agree with Frankie but I would ignore the word Angus in her post. Cows are cows. Doesn't matter if they are Angus, Lim, Simm, whatever. AI-sired will likely be more advanced genetically. That said if you are wanting to move up calving dates, you have to be very dedicated to watching the cows if you plan on AI breeding. As has been said already the "easiest" would be to throw the bull in early. I always say you will pay for that convenience but to each his own.Frankie":23krrjp1 said:

They are registered. I hear what you're saying and it is something of a dilemma. I intentionally bought some really high end herd bulls this year - one was the top SVF Bandolier son to sell at the Sunny Valley dispersal.. I actually really want some calves out of these bulls too - especially the Bandolier son. I have some bandolier daughters and they're fantastic . . . and with bandolier semen at $1000 a straw it seemed the most realistic way to maintain some of those genetics in my own herd. Sadly you're right though . . . a lot of people will just ask "was it an AI calf or herd bull calf" without looking at overall genetic picture.

Move them up first and when they are where you want them you can AI them to expensive semen with better success.
If your clean up bull is a good one ,your registered calves will still be worth something. AI'ing and moving them up, your success rate is not going to be very high, especially because you want to breed on an induced heat. If you are set on AI'ing them, then induce them and breed them on their next NATURAL heat.

What is considered an average conception rate with natural service while pushing up calving dates?

Dun, tell us more about the induced heat. I have problems getting them bred sometimes.
