Question for cow pollinator or othe A.I. gurus

[HOSS]

I observed a cow in standing heat this afternoon around 4pm. This is a natural heat. I am following the am / pm rule. I can't breed her at 4 in the morning due to the impossible logistics of help getting her up off of a 40 acre field by myself. I can breed her around 7 in the morning. How much negative differential in success will the 3 additional hours make? Thanks.

Not much. Not anywhere near enough to make it worth your time to try to do it three hours earlier.

Thank you. 90% of my breeding is TAI so I do not have much success / fail experience on breeding to natural heat.

If it's easier for you, you can always run them up and breed them at the first signs of estrus and hit them with gnrh and still have really good results. In fact, you can get decent conception without the gnrh.

If I breed her in the morning should I go ahead and hit her with the gnrh or will it be a waste of time at that point?

It's a waste at that point.

It's a waste at that point.

My ROT is if they are still standing I hit them with GnRH, can;t hurt and it helps my peace of mind. Years ago we had a cow that we AIed and she missed, AIed her again and she missed again so the bull go her. The next year I kept an eye on her and the first AI she was still standing 24 hours after breeding her. She missed so I gave her a shot of GnRH when I AIed her and she was still standing 24 hours later, but she setteled. Obviosuly she was the odd ball but since then I go by my ROT and don;t have to worry about watching her to see when she goes out.

im no Guru but when the rod comes out GNRH goes in. the one that taught me says are you gonna let $2 keep you from getting her settled so if its timed or natural they get it.

GnRH is inexpensive so why not give her a jump start????

Got her bred by 7 this morning. Had little difficulty unless you count the swarm of wasps that attacked me. Evidently they built a nest in the tubing of my squeeze chute. When you have an arm up a cows butt and the other hand engage with the breeding rod being stung by wasps is pretty high up on my list of annoying things :mad:

Seems strange but they sure do seem to have a liking for squeeze chutes. Anymore a standard piece of equipment I have with me if I'm going to use the squeeze is a can of wasp/hornet spray

Our teco has expanding foam everywhere, spray squeeze once every other week. Got 12 ai'd this weekend no wasps this year for sure lol

I had a sparrow (nesting) infestation in the shed where I store the AI gear one summer. It took me a few times to work out why I was itching every time I inseminated a cow. Turned out the funny dusty stuff all over the surface of everything in that warm shed was bird lice. As I prepared my straw, those things climbed aboard and it wasn't until I was elbow-deep in cow that they climbed high enough up my arms to start tickling. It didn't do much for my concentration!

I agree with you 100%

While doing AI for some others, I suggest they breed as soon as they can get the cow up at first signs. It helped with increase cows bred. IMO the cow was in heat earlier, but they didn't see her.

Well I put an estrotec patch on this cow at day 18. It is now day 23 since I A.I.'d her and the patch has not changed color nor have I saw any heat behavior. Maybe it was a success.....at least I am hopeful. Time will tell for sure.
