What is the weight of a adult horse?
Depends what breed and what they are going to be used for.
Gestation period time: 11 months After they are born they are called a foal for a year until they become a yearling. By the time the horse is a two year old, it is its adult size and weight. Next, a horse becomes an adult. Then it becomes a geriatric horse. When it's a teenager (or even in it's twenties) it will start showing "ageing signs".
Its is very difficult to answer this question. It is much too broad. Different breeds, whether juvenile or adult, can be very different. You can't compare a Shetland pony and a Clydedale. The average size saddle horse at 15.2HH will weigh 800 to 1100 lbs. This same horse as a weanling can weight 200 to 300 lbs.
Keep in mind this does not apply to all equine.
