Horses produce up to 60 litres of acidic gastric juices each day.   Gut Nutrition Formula (GNF) reduces the acid build-up in the stomach reducing the risk of stomach ulcers.  GNF protects the stomach wall from acid and helps heal ulcers.

Here’s how:

A horse is a grazing animal, spending two thirds of the day grazing and is designed to digest a small but steady stream of forage throughout the day.  As they graze, they produce large amounts of saliva and maintain a mixture of saliva and roughage in their stomach most, if not all, of the time.  It is this mixture that buffers the acid in the stomach, preventing the formation of stomach ulcers.

The horse’s stomach is separated into upper and lower parts. The lower portion is lined with glandular mucosa and is where the acid is produced. That’s where the acid is meant to reside and digest food. The glandular mucosa has a thick mucus layer, robust blood flow, and naturally-produced sodium bicarbonate, all of which protect the lower portion of the stomach from the acid.

The upper part of the stomach, however, is lined with squamous mucosa and doesn’t have the same protection from the acid.  If the stomach doesn’t have any food in it, the acidic juice can accumulate and reach or splash up and contact the unprotected upper part of the stomach, burning the squamous lining causing stomach ulcers.

GNF contains pre-biotics to feed the good bacteria in the hind gut and helps the hind gut return to better health and your horse can digest it’s feed and hold condition better.
