Abstract
An improved method of producing silage for use as ruminant feed, whereby green fodders are ensiled with about 1 percent of an additive containing methylolurea and methylenediurea in a weight ratio between 1 and 20 to 1, sufficient free urea to prevent reversion to free formaldehyde, a buffering agent to maintain pH, and water. The method preserves contained natural protein, substantially prevents growth of mold, and increases crude protein content, palatability, and feed efficacy. Operative feature of the method is the discovery that a methylolureamethylenediurea-urea solution may be reacted to a point where it will not sterilize the bacteria needed to ferment contained sugars to carboxylic acids, but will protect the silage against mold formation and natural protein degradation. A process for producing the required silage additive from urea, formaldehyde, ammonia, alkali, and water is provided.
