She definitely took from the AI, we had an ultrasound done. She's starting to bag up, but no vulva swelling or discharge. I may give it a few more days before I call the vet.
I have a cow that was AI'd and the 283 day gestation period had her calving on 9/15. I know older cows (she's seven) will sometimes calve a little past the 283 days, but at what point should I be concerned? She's never calved late.
