Here are the facts.
Cows are baby machines.
If a cow is not bred or if she does not have a calf on the ground, she's wasting money.
She's basically taking up space and eating the grass. She is not earning her keep. The cheapest and easiest ( not quite the cleanest) way to determine if she is bred or not, is to preg check her.
No EPT tests out here.
Load her in the chute,
and feel for a calf.
He loves his job. He really does.
