Would a gelding that is proud cut or gelded late display stallion like behaviour around mares? When Buzz is around the mares here he arches his neck, snorts, roars, raises his tail, paws at them. But doesn't do it around the geldings.
According to his papers and some history I found he wasn't gelded til late. I'm not 100% sure if his last owner did it or not, but he was 7 when she got him.
Are you 100% sure he was gelded? He could be a ridgling if you're not sure. Also if he was gelded late, could be that he had one testicle that hadnt descended and that's why they were waiting, to see if it would. In that case they may not have removed the non descended one completely (it happens ) if it concerns you at all or is causing too many problems I would get a vet to see his level of testosterone in his system to give you some kind of idea....
I'm 99.9999% sure he's gelded. There are no testicles that I can see and he has been kept with mares for at least the last 7 years. So far he hasn't hurt anyone, I'm going to be keeping an eye on him for sure.
I had one gelding gelded as a 2 year old that did that and had no testicles hidden or anything, but we had another gelding who it turned out was a crypt and managed to breed a mare!!!! You may want to get your vet to check it out. He had been with mares all his life, and this didn't happen until he was about 11.
It's actually not that rare sadly, adn people will sell one without warning you. Crypt means one testicle is still up in the body cavity. Generally they can only produce testosterone and can't impregnate a mare, but sometimes it happens.
Some horses retain sexual behaviors after gelding and are often called "proud cut". In the past this was said to be due to some testicular tissue being missed during the gelding procedure allowing testosterone production (but not sperm production) to continue. In some cases, this may have been true, especially considering the variety of crude methods of castration practiced over the last 2000 years. However, today, with the availability of restraining drugs and the level of knowledge and surgical techniques, it is unlikely that missed testicular tissue is the cause for the estimated 25 percent of geldings that are said to exhibit some type of stallion behaviors. Since the adrenal glands (located near the kidneys) also produce testosterone, it is thought that the cause of so-called "proud cut" behavior may be due to the (hyper)activity of a particular horse's adrenal glands. Other stallion-like behaviors may simply be poor manners due to inadequate training.
