Aviacil has a strong acidifying effect in the stomach. For optimal protein digestion the pH in the stomach needs to be around 3. Aviacil reduces the buffer capacity of the feed, it will maintain its acidifying abilities in the stomach. This way, Aviacil will achieve a fast reduction of the pH value in the stomach, creating an optimal environment for digestion of proteins. Aviacil lowers the pH in the stomach of the animal to approximately 3 which prevents the growth of pathogenic bacteria like E-Coli and Salmonella.
