In horses, many diseases are associated with the consumption of diets with high levels of grain or nonstructural carbohydrates. Excess of these foods, often con promotes lactic fermentation and intestinal acidosis, causing colic and laminitis. The addition of alkalizing in the diet does not have the same effect on horses as compared to ruminants. This study aimed to use different alkalizing and associations between them, in an attempt to reverse the process and control of acidosis in the large intestine of horses. 20 animals underwent four treatments with a control, one with Al2(OH)3, Mg(OH)2, and finally a combination thereof. The animals were evaluated for changes in fecal pH and clinical changes resulting from the administered products such as occurrence of constipation or diarrhea, and abdominal discomfort. It is concluded that administration of magnesium hydroxide (Mg (OH)2 at a dose of 20 g / 100 kg body weight and the combination of magnesium hydroxide and aluminum hydroxide 20g Al (OH) 3 + 20 g Mg (OH) 2 / 100 kg live weight, were able to significantly (P<0,05) alter the fecal pH, 24 hours after administration, without digestive disorders or significant abdominal discomfort
