What are colts and stallions?
Both are male horses. A colt is a young male horse under 3 years old, though he can be physically able to breed above one year old. A stallion is a male horse over that age. In both cases, if the horse is castrated it’s known as a Gelding. Stallions are usually only kept specifically for breeding, as they are much more difficult and unpredictable to handle than geldings. The obvious physical difference in stallions is that their testes are intact, but extra muscling especially in the neck may be obvious. Behaviourally a stallion is more inclined to be protective of any mares he considers “his”, more likely to be dominant over geldings and will react strongly to the presence of a mare in heat.
