40 Million cells or multiple straws/breedings

Postby Air gator » Sun Jun 11, 2017 8:38 am

What would be the most effective strategy? You have a heifer that has missed on A.I. and the season is getting late.
What would work better? Breeding her with 40 million cell straws or inseminating her with 2 straws (with normal number of cells) or breeding her twice (and at what intervals?).

Thousands of cows are bred with half cc straws. If she didn't breed with a half cc straw what make you think more will help?

I'd breed her twice, the 1st when you think she is right and the 2nd the next am or pm regardless of whether she is still standing.

I often have suggested to farmers to do 2 breedings when I was doing relief for SS years ago. Once when you see them and then again the next am or pm as wbvs58 said. Also, I would give her a shot of gnrh. This is if you don't have access to a bull, which will of course get her several times during her heat if he can. I prefer the 2x at about 12 hours or so apart. Some seem to release the egg later in the heat cycle and too early a breeding may miss it. My guernseys were really bad for ovulating late after they were past standing heat.

Ken

I totally agree, but like fj recommended, I would give a GNRH with the first breeding.

Suzanne, do your heifers stand for 3 hours or 12 hours normally?

Thank you Farmer Jan, Jeanne and Suzorse. I have a 4 month old bull calf who has been helping with heat detection so maybe I will do OK.

This is the most logical choice! Why waste time and money on a female that will not stick to AI when the bull can settle her? Turn her out with the bull, if she settles to calve early in your program then attempt AI with her the next year. This is why we sync and only do 1 heat cycle with our AI group because if they don't come in heat or settle to the AI service the bull will likely settle them on the next heat cycle and she'll hopefully calve early enough she may get another shot at AI the next breeding season. We had a huge gap between our last 2 calves this year with the next to last calf on April 10th and the last calf on May 30th. If that last cow doesn't breed up to about May 1 next year she probably is going to town. She usually weans an above average calf but having cows that are just calving the same time you turn the bull out is a pain in the arse for us. Like to keep our calving season to start late Feb and be done before May 1.

Some people don't have a bull to "turn out" to.
SPH, if you don't want late calves, why not pull the bull on last calving date that works for you?
