how long is a horse's digestive system
Small Intestine. Digesta passes from the stomach into the small intestine. The small intestine is approximately 28% of the horsesâ digestive tract, is 15-22m long and has a volume of 55-70 litres. This is the major site of digestion in the modern performance horse.f the horse is fasted, it will take 24 hours for the stomach to clear. It has long been a question as to what you should feed a horse first, grain or hay. Because of their density, grains tend to stay in the stomach longer, but it has not been proved to be advantageous to feed either first.
