This is true , even with slow feed nets some horses will eat themselves into insulin resistance and laminitis!
The horse pictured here is genetically predisposed to equine metabolic syndrome (EMS) and was given free choice, unlimited access to hay. He developed obesity, hyperinsulinemia, and ultimately insulin-induced laminitis. When he could no longer stand, hay was kept in front of him 24/7.
After getting a hay analysis, the owner was advised how much to feed based on actual energy requirements (calories consumed vs. calories expended), to weigh the hay, and to use slow feeders. When the horse was sound, the owner scattered the hay over several acres. The horse made a full recovery and achieved his ideal weight in 9 months.
For weight loss, a good rule of thumb is to feed 1.5% of current weight, or 2.0% of ideal body weight in hay (lbs/day), whichever is more. Example: Overweight horse of 1200 lbs, ideal weight is 1000 lbs. [1200 lbs x 0.015 = 18 lbs/day; 1000 lbs x 0.02 = 20 lbs/day]. Use of slow feeders or small hole hay nets will slow consumption.
