Cattle and dairy producers are under continuous pressure to lower costs, improve feed efficiency, maintain optimal health, and comply with ever-increasing environmental regulation.

St. Cloud Zeolite adsorbs potentially harmful ammonia generated during the digestive process and studies have found that the introduction of St. Cloud Zeolite to the feed has increased rumen buffering, reduced manure nitrogen loss, reduced liver abscesses and improved feed conversion.

In short, the results have been impressive and because of its unique attributes, St. Cloud Zeolite is used by more feedlots than any other zeolite and has become the premier zeolite additive in the country today.
