I’m often asked how we can have a cow/calf operation without a bull. Well, David is the “bull” in a way. We artificially inseminate all of our cows (or at least that’s the plan). We use a “Marker Bull” or some call it a “Gomer Bull”.
A marker bull is used to detect whether the cow is in “season”. He is surgically altered to maintain his amorosity but can not actually breed the cow.
He wears a halter with a chin ball attached to it that is filled with colored ink. When the cow comes into season he leaves his mark on her back and we know she is ready to breed.
She is then run down the chute and is artificially inseminated with higher quality bull semen. Marker bulls are animals that have less desirable genetics but I’m told the best “Gomers” are Jersey bulls because they are more lascivious then most breeds. I think he is kind of cute.
Now a cover bull will be brought in to make sure that all the cows are bred.
