Dr. Arnold Hippen Receives US Patent

Dr. Arnold Hippen Professor of Dairy Science is co-inventor for a new US Patent entitled Carbohydrate ruminant feed energy supplement and method. This patent involves a carbohydrate ruminant feed energy supplement and method for alleviating a negative energy balance in ruminant animals. It includes forming a ruminally protected carbohydrate, preferably non insulin stimulating, and feeding the ruminally protected carbohydrate to a ruminant animal. The invention is a feedstuff designed to prevent or alleviate the metabolic effects of the negative energy balance associated with parturition and periods of decreased feed intake in ruminant animals. The proposed feedstuff provides carbohydrate-based energy substrate to tissues of the animal even in the presence of low blood insulin concentrations which are characteristic of a negative energy balance. One example of such a feedstuff consists of fructose enrobed in a matrix to provide protection of the fructose from ruminal degradation and to deliver the compound for postruminal absorption. This feed is designed to deliver fructose, or similar carbohydrate, orally at amounts of 5 gm to 10 kg/d to each animal.
