Horses are trickle feeders. They need access to feed 18 hours a day and they need to eat at least 1.5 to 2% of their body weight per day just to maintain their weight.
It takes 4-6 hours for a horse to completely empty its stomach. Horses have no gall bladder and constantly release gastric acid. If there is no feed in there to soak it up a horse will develop ulcers. Having an empty stomach will cause a horse to stress. They will release cortisol. Cortisol lowers blocks insulin and causes high blood glucose levels. This process cause leptin resistance and eventually equine metabolic syndrome. And that’s a nasty bastard, a major contributor to laminitis.
Horses need only 20 minutes rem sleep in a 24 hour period. So the rest of the time they are eating. If you feed your horse at 5 in the morning and they have finished it by 8am. That means by 12pm they have an empty stomach and are entering starvation stress mode.
So if you are a trainer or breaker and you tie up a horse for 6 hours to teach it a lesson. You have potentially just started that horse down the path of having ulcers. And that’s really sh*tty.
