P4t—Lancaster Farming. Saturday, A| Digestation Studies in the Metabolism Unit Help Lead To New and Improved Milking Rations. Both basic and applied research are part of Purina's Dairy research program. One important facility at the Dairy Research Center is the six cow Metabolism Unit. Here daily feed and water intake, as well as milk production, are carefully measured along with total excrement. These measurements enable Purina scientists to study the cow’s digestion and accurately determine the nutritional value and utilization of feed ingredients. Data from this research is especially valuable in developing new and improved High Performance Milking rations. ' > r:-\ PHONE 717-442-410 717-764-3301 PARADISE, PA 17562 HIGH BROS.

The removable “window” or fistula in the side of the cow in the metabolism stall was inserted surgicajly and painlessly allowing the cow to calve and function normally. Laboratory analyses of rumen samples taken through the opening provide a broad range of vital data used in studying rumen micro organisms and their influence on such functions as protein synthesis, fermentation, butterfat production and forage utilization. Information from these studies helps Purina scientists develop rations that make more efficient use of feed ingredients for maximum income over feed cost. WEST WILLOW FARMERS ASSN„ INC.
