DB-Lanc«ster Farming Saturday, April 13,1991 Intestine Feeding Big Topic Of Barn Seminar BERNVCLLE (Berks Co.) F.M. Brown’s Sons, Inc. recently 'concluded a series of bam seminars for customers and Mends, attended by more than 175 dairymen representing 130 dairy operations. Dr. Carl Brown, sales manager, set the stage for *he meeting by presenting a summary of why we need to look at more than just feed ing the rumen. “In today’s dairy industry, we are competing against some very efficient animals such as the turkey, hog, and even the fish,” Brown said. “Research has done much to maximize rumen efficiency. The dairy industry must always maximize forage digestion to be efficient, but the digestion process includes large areas past the rumen.” Other species ferment, digest, and harvest all their nutrients in the intestine, but until recendy this area was almost ignored by dairy research, he said. “Today we realize that once we maximize rumen efficiency we must look to feeds that improve nutrient harvest in the intestinal area." Dr. Walter Kennett, Brown’s nutritionist, followed with a discus sion of why achieving peak milk yield is critical. In a cow milking 50 pounds of milk, maintenance requirements account for 36 percent bf the total energy consumed. In a cow milking 100 pounds of milk, maintenance only consumes 22 percent of the total energy, allowing the conversion of 78 percent of energy consumed to productive purposes. Body fill is one of two major factors which affect energy intake. He then reviewed how certain components of plant cells increase fill and thus reduce energy digestion. Products such as sodium bicarbonate and yeast culture enhance rumen energy digestion offsetting prob lems associated with higher fiber intake and low rumen pH. “Once forage intake and digestion is maximized, then we need to combine nutrients flowing out of the rumen with nutrients which bypass the rumen digestive process to allow the optimum genetic potential of the cow to express itself,” he said. Depending on quality of forages, forage intake, ration balance, etc., rumen fermentation will support 60 to 80 pounds of milk. In addition, cows can consume “fat-added” diets and use body fat stores to provide energy for much higher peak lactation yields. Protein, and specifically amino acids which build milk and body protein, then become the limiting factor in maximum performance. Based on real feeding situations, Kennett then showed how investing in the right forms of rumen undegradable protein would yield hand some returns under todays feed prices. Following Kennett was Alan Larsen, eastern regional sales mana ger for Bio-Techniques Lab Inc.

Ashford Resigns From J.I. Case HOUSTON, Texas Tenneco Inc. announced today that James K. Ashford will resign as presi dent and chief executive officer of JI Case, a unit of Tenneco, effec tive April 15. He also is resigning as an executive vice president and member of the board of directors of Tenneco. James L.

Ketelsen has the oversight respon sibility for Case at the parent com pany level in Houston and has an extensive background in the agri cultural and construction equip ment industry. "Jim Ashford, in his career at Tenneco, has made a significant contribution to the company both in his earlier posidon in the auto motive parts division and particu larly in the critical role he has played over the past several years in leading the turnaround at Case. I regret that this decision has been made, but I understand his reasons and wish him well,” Ketelsen said During the transition period, Kenneth L. Otto, a Tenneco senior vice president, has been assigned the responsibility of directly coor dinating day-to-day activities at Case. Otto currently is responsible for Tenneco’s world-wide human relations, productivity, and quality programs and other administrative functions.
