AMES - Dr. Timothy "Tim" Scott Stahly, 57, of Ames, Iowa, died Tuesday, February 27, 2007 at University Hospitals and Clinic in Iowa City, Iowa. Tim was born May 10, 1949 at Huron, South Dakota, the son of Vernon and Frances (Miner) Stahly. He was united in marriage to Sharon Kay Chenoweth on August 13, 1966 in Mitchell, South Dakota. Sharon preceded Tim in death on July 9, 2004. Tim attended rural school in South Dakota and was the first person to finish his senior year of high school while a freshman at South Dakota State University where he earned his B.S. and Master's Degree. He earned his Ph.D. in swine nutrition at the University of Nebraska. Dr. Stahly taught at the University of Kentucky for 16 years before joining the faculty at Iowa State University in 1991. He was a researcher and consultant in swine nutrition. Dr. Stahly's innovative research has greatly benefited the swine industry. His research focused on the effects of genetics, health status, and environmental conditions on the pig's requirements for energy, amino acids, and B-complex vitamins. The practice of adjusting diets to environmental conditions, health status, and genetic background of pigs is accepted worldwide and much of this traces back to Dr. Stahly's discoveries. Many of the growth models available in the swine industry today use information developed by his research. Dr. Stahly was in high demand as a speaker at technical conferences and symposia in the United States and abroad and had given papers at 85 conferences in 10 years. In 1983, Dr. Stahly received a patent for improving the metabolic stability and survival of neonatal pigs. Dr. Stahly was active in the ASAS, serving as Midwestern Section president, was a member of the ASA board of directors, served on the editorial board of the "Journal of Animal Science", and was a member of the Collegiate Presbyterian of Ames. Tim enjoyed his grandchildren and finding humor in everyday life. He had an enjoyment for horses and hosting Kentucky Derby parties at his home in Ames. An avid pheasant hunter, Tim loved going home to the ranch in South Dakota. He is survived by a daughter: Lisa Stahly of Fairfax, California; 2 sons: Charles Stahly of Lexington, Kentucky, Ben Stahly of Ames, Iowa; 2 grandchildren: Dylan, who lived with Tim, and Althea; 1 sister: Louise Bauman of Huron, South Dakota; and 3 brothers: Michael Stahly of Cavour, South Dakota, Steven Stahly of Naples, Florida and Daniel Stahly of Sioux Falls, South Dakota.
