Midwestern Section A.S.A.S. Younger Scientist Award for Excellence in Research, Teaching and Extension

Werner G. Bergen was born in Warstade, West Germany, and immigrated to the United States as a boy of only 12 years of age. He was awarded the B.S. degree with distinction in Dairy Science in 1964, the M.S. degree in Animal Science in 1966 and the Ph.D. degree in Nutrition in 1967 — all from The Ohio State University. He then joined the Animal Husbandry Department at Michigan State University where he has played a key role in developing an outstanding program in ruminant nutrition research and teaching.

Dr. Bergen and his colleagues have recently demonstrated that growing steers have rather precise amino acid requirements, which are normally met by rumen synthesis, but only if the ration provides certain basic building stones in the form of adequate energy and available nitrogen. They confirmed that true protein synthesis occurs in the rumen, and demonstrated a direct relationship between the quantity of protein reaching the lower gut and the level of essential amino acids in the blood plasma. He and his co-workers have shown that viral and bacterial infections decrease absorption from the gut and cause protein deficiencies on an otherwise adequate diet.
