I have an April 2017 heifer that we have Ai'd once and had with the bull for two cycles.
She has short cycled (16-17 days) after each breeding.
She was a single birth and I bought her at 6 months. She was a virgin heifer when she was AI bred at 14 months. She is now over 1000 lbs and moderate condition now (not too fat or skinny).
I noticed that when she was with the bull she would not stand for him until every other cow/heifer/steer had mounted her. She also only stood for him for one breeding each cycle. Held her tail to the side when he bred her so I am sure he bred her.
He had other cows bred and settled during the same time period and was tested free of all issues. Excellent mobility, no trich and all cattle are vaccinated 2x per year including vitamin and wormed.
The only thing that my AI tech/vet and I came up with is maybe she is not actually expelling a CL and if she is bred she will short cycle due to that-- otherwise she has normal 20.5 day heat cycles.
We are trying CIDR, GnRH, Lute sync with 2 others at the same time to see if hormone treatment will make her settle.
Any other suggestions? Has anyone else had these issues?
Really would prefer not to butcher her if there is any way I can get her bred-- she was expensive since she is AU genetics and she is puppy-dog friendly. Even if she has terminal offspring...
