Prolonged exposure of the stomach to gastric acid can cause damage to the stomach lining, resulting in a painful condition for the horse. Horses with stomach damage can show irritability, poor appetite, and resistance to work. Research has shown that as many as 90% of horses in training have some level of stomach damage. Neigh-Lox is designed to protect the digestive tract against excess gastric acid and provide a physical protective lining in the stomach and small intestine. Suitable for horses which may be at risk of gastric irritation, gastric sensitivity, loss of appetite, loose manure, weight loss, in training or work, on high grain diets, experiencing stressful conditions e.g. travel, show/sales preparation, during weaning, experiencing changes in feeding routine or reduced forage intake, prone to loss of appetite after work, competition or travel, have stable vices or abnormally unsettled behaviour.
