In Brazil, sugar cane is generally used as silage to feed livestock. However, when silage shows a fermentative pattern characterized by high ethanol production and sugar losses due to the action of yeasts, it results in a reduction of its nutritional value as a result of dry matter (DM) losses.

Urea is often used as an additive in silage as it transforms into ammonia and reacts with water to form ammonium hydroxide. A product has been developed called protected urea” that has a controlled release of ammonia and reduces the buffering effect caused by conventional urea; it also allows for a greater concentration to be used at ensiling.
