They don't. The are not genetically similar enough to reproduce.
Alpacas have a gestation period of around 11 months. Female alpacas give birth to a single cria (baby alpaca) on average, although twins are rare. The birthing process is typically smooth, with the cria being able to stand, walk, and nurse within a few hours of being born.
Horses are Polygyny in their breeding style. A stallion will mate with any mare in his harem that is in heat, and will try to steal mares from other stallions. A mare typically only mates with the current band stallion, but may wander off and breed with another available stallion.
Two animals from different breeds may mate due to proximity and opportunity, lack of available mates within their own breed, or simply following their natural instincts to reproduce. While offspring from such pairings can sometimes be infertile or exhibit mixed traits, some breeders intentionally crossbreed to achieve desired qualities in the offspring.
Yes, a donkey can get pregnant from horse sperm. Not many people breed animals like this anymore, but that is how people use to get light weighted horses, but it was usually a horse getting pregnant from donkey sperm. Any animal of the same species can get pregnant from each other. For example, a dog and a wolf, a wolf and a coyote, a tiger and a lion, a horse and a zebra, a horse and a donkey, all of these are possible.
dogs
Sheep, donkeys. horses, alpacas and llamas
It does depend what your horse and/or alpaca can put up with and what their temperament is like but you can. Alpacas can get along with any livestock.
Before the introduction of horses to the new world, llamas and alpacas were used to transport goods.
no, no horses do
They can, but usually not. Horses will mostly only mate once the mare is in heat.
no but humans can make horses mate with the same patner all there life
Yes, most alpacas will be just fine in a pasture with other herbivores (horses, cattle, sheep, goats). However, if you have two or more alpacas, you'll likely find they form a herd by themselves and do not associate much with the other animals in the pasture.
Alpacas move in the same way horses or cattle move. Four legs. They walk, sort of trot, and then sort of canter. They don't crawl or run. They have even paces.
Horses mate for the same reason that all other animals including humans mate. It is to create offspring and keep a particular species alive. Horses are breed typically to sell or use for show.
horses are sent to stud farms
No they don't. They mate between the ages of 20 to 25.
If you mean the same breed, not always.
