What is a Gomer Bull?

 

[la4angus]

A Gomer Bull is a bull that has his penis surgically altered so that he can't breed any cows. He is used for heat detection.

 

[paul swisher]

A surgically altered bull (not casterated) so he cannot breed but will mount. Used to detect heat for AI.

While that is a Gomer, usually called a side winder, a vasectomized bull serves the same function.
The vasectomy route is more common because of the complexity of the surgery required to make them a sidewinder.

How do they surgically alter the bull? What do they do?

A sidewinder (penile deviation) has the penis routed up the side under the skin and out the side. Otherwise they can be vasectomized by cutting, I think, the vas diverens. I've also seen the tail of the epididymis clipped. A side winder can still be collected for AI, the others make him sterile.

Im not being ignorant, but the "penile" is moved?

 

[Ann Bledsoe]

The penis is moved from it's normal position under the belly to a spot on the flank, the operation is called penile deviation.

& in other words, his penis now comes out his side instead of under his belly like normal. when he mounts a cow it is not in position to breed her.

Thirty odd years ago it was fairly common in some AI studs. The technician could collect without having to get as close to the bull.

How much does it cost to make a bull a sidewinder? Do they do that when they are young or can you do it to a bull that has previously been a herd sire?
