If neutering or spaying an animal is necessary to prevent unwanted babies, why not just give them a hysterectomy or vasectomy instead? Do the remaining hormones still have other negative effects?
In: Biology
Spaying is a hysterectomy plus some.
Neutering can be notably quicker than a vasectomy. In a vasectomy you cut open the sack, snip the tubes, and tie them off. In neutering you cut it open and rip them out. Significantly faster when doing it on a large scale with things like sheep. The other option is banding but that is quite painful for the animal for a long time.
There are also significant behavioral differences between a neutered male and an unneutered male. Horses aren’t neutered for population control, they’re neutered because Stallions are assholes and Geldings(neutered horses) aren’t. Same goes for Bulls vs Steer.
There isn’t as much of a behavior difference between spayed and unspayed animals that aren’t prone to getting knocked up at random, so spaying is almost never done on large animals where it is a much more extensive procedure like horses
