Synchronized but no heat sign

[kndcattle]

I set two groups of cows this year.  We put cidrs in and give gnrh on day one.  Day seven pull cidrs and give lutalyse.  Then we heat detect and AI.  The first group all the cows came in heat with no problems.  This last group all came in but one.  At what point after lutalyse do you just breed anything not showing heat.  Also is there much chance of her taking at that point.

We ran into this trouble for the first time this year. We had one do that, but we figured what the heck, we have spent the time and money for syncing her up, so we mise well toss some semen in her and hope for the best. So far it appears as though she has stuck. We should have seen her coming around yesterday or today, but as it sits she seems to have stuck. We just breed them anyways and hope for the best. Best of luck to you.

Last year we were going to breed nonresponders at 72 hours post lutelyze.  However we waited them out and had 3 show heat at 108 hours post lutelyze.  2 of the 3 stuck to AI.

We synched 49 head and time bred the majority. We saw no difference in conception between obvious heat and time bred.

We bred at 72 hours.  That's interesting that you waited them out and got to 108 hours and still got 2 of 3.  I'm not brave enough to try that after all the money spent but good to know it could work if something comes up.

Was going to post the same question.....  Synced 12....  Six came in and stood, three about twelve hour earlier then expected, two right on schedule, waited another one out.....  The other six never showed any signs of standing.....  Was going to go ahead and time breed but it just didn't "feel right" to have them not showing.....  The bull wil probably be happy in about 20 days from now.  They should have been time bred sat night Sunday morning, but like I said, weren't showing or even mucous.

JMO, I think that some of you would see better results as far as standing heats are concerned by using estrumate instead of Lute. It's been our experience here that the heats are stronger by using estrumate.

 

[ejoe326]

Excellent point CAB.  We made the switch to Estrumate after battling Lute for several years.  We've seen a noticeable jump in conception since making the switch.

I would not be afraid to breed even if they show absolutely no sign of heat.  We have and have settled them successfully.

What kind of conception rate are you getting with your non responders. We have been syncing for the past couple years and only had a small handful be non responders and usually get a couple to stick. But this year out of a group of 25 I had almost half be non responders and it has me worried that I'm not going to have very good conception rates.

We implant CIDR's and leave them in 7-10 days. Give lute when we pull them. 48 hours later GnRh and breed 24 after that. Takes out the guessing and doesn't look like it should add any cost to the program you are using now.

You give the GNRH 24 hours before you breed? I'm not a AI specialist but wouldn't the egg already be pasted by the time you breed?

The timed AI protocols that I've seen do the same the as what Rackranch said... Give a shot of GNRH then breed.

That is what my vet suggests. He believes they do better with 9-10 days with the CIDR.  We give Lute at the time we pull the CIDR. We wait 48 hours and give the GNRH and breed 24 hours later yes. Our guy that AI's actually bred at about 26 hours after GNRH. There is a possibility that they will come into heat at the 48 hour mark but we have never had one do it. 2 of our 3 we just bred took. The one that did not take was showing a few signs of heat when we implated which may have affected her outcome.  Just implated her again today.

I agree with CAB, this year we timed AI but switched from Lute to Estrumate and had way stronger heats it seemed like to me. Just seen the cows riding each other way more then when we used Lute the last couple years, I really like what I have seen using Estrumate. I used the 7 day cidr synch, cidr and GNRH at day 1, puled cidr and PG (Estrumate) on day 7, 60-66 hours after PG AI and another shot of GNRH. I split the 60-66 hours and timed AI at 63 hours after the PG. But again, I really like what I have seen from using Estrumate for the 1st year.

This year i have had a heck of a time getting cows to come into heat and I do not know why. I had a 1st calf heifer that got a the 7 day cidr protocol and never came in. So 10 days later i gave her a shot of lut. never came in. 10 days after that another one and still nothing. Also did the same thing with two cows and they havent shown any signs. I have estrotect patches on them since I have a job off the farm but still try and look for other signs in the morning and night.  I would say they are at a BCS of 5.5-6 and have free choice wind and rain mineral year round. Not trying to high jack the thread but anybody have any idea what would be going on here? These are cows that I have responded well to the protocol in the past.

About half the non responders..
