We pregnancy-checked my parents’ spring-calving cows a few weeks ago. Cow 521 came up open. I have always liked this cow and I posted a picture of her a couple of years ago, shown below.
I am tempted to add her to my fall-calving herd which is in the midst of breeding season now, but instead I chose to buy cow 447, which the vet said he thought may be pregnant, but only a month along. 447 is a better bet than 521 because it’s unknown why 521 is open. She may have reproductive problems which render her infertile.
Still, it’s sad to see her go.

What happens to her–where does she go?
goodbye 521. You were a good girl, even though you’re ‘open’. the warmth of your spirit lives on…

Thanks Amy and Tara.
When a cow is not productive, (pregnant or nursing), she becomes beef.
