Acidosis in Dairy Cows

Congrats for the article. You are right, the first step to prevent rumen acidosis is nutritional management. However, once a suitable nutritional management has been established, it is really important to increase the conversion of lactic acid into propionic acid by means of lactic acid utilizers bacteria. To achieve this, the supplementation with salts of malic acid is a great solution, since this compounds increase the capacity of Selenomonas ruminantium (lactic acid utilizer) to convert lactic acid into propionic acid. When given in forms of salts, their effects are better.
