I will add that my normally docile "pet" Hereford heifer would go bat-crap crazy when she was in heat. She lived with my horses (she was bottle fed and lived IN THE HOUSE for 6 weeks because she was a premie and had been attacked by a coyote and she was TERRIFIED of the cattle because we waited too long to move her from the horse area to the cattle pasture. Anyway.) and she would "fall in love" with my wheelbarrow that I used to clean stalls - every. single. month. - and I literally could not push the wheelbarrow from the barn to the manure pile in the pasture because all she wanted to do was mount it.
Cows in heat can sometimes be worse than women with PMS.
I agree with others that she likely didn't get bred, didn't take or aborted...
Also, I hope she has more room to roam than just a stall. Cattle are playful animals that need enough space to be silly every now and then. She doesn't need acres and acres, our show cattle live in a 70' round pen and that is enough room for them to be silly when the mood strikes.
My children - even my 65lb 9-yr old son - handle our well-over-1000lb show steers multiple times a day, brushing and loving on them. BUT!!! the steers are either in a grooming chute or hard tied with a halter and neck rope on when we are really messing with them. Of course, we scratch and love on them when we feed them and water them, but we don't linger so long as to give them a chance to be rowdy. Cattle are smart, just like horses, and you are always "training" them whenever you are around them, whether you know it or not. Like others said, you ALWAYS have to be the dominant one, because if you let them "win" then they will "treat" you like they treat other cattle in a herd, and it IS NOT always gentle. Cattle herds are ROUGH with one another - doesn't hurt them at all - but it can easily injure or even kill a human.[/
We kept her in a stall for the first several days as per the breeders advice. The stall is 12x36 (it's a three stall one). She has 10 acres for just her, another jersey, and a horse. I was advised to keep her in the stall for a few days, so yes she was on the stall at the time. In all honestly I am worried that she isn't bred now She hasn't been acting like that today, but I also haven't been giving "excessive attention" these last few days. I'm going to have a very come out and pregnancy test her. Would it be obvious in her belly if she was due June 10th?
