Jacob Guffey, Bradford County extension director, has retired from Penn State Cooperative Ex tension after 40 years of service. A native of Elizabeth, Alle gheny County, Guffey is an expert on dairy fanning and operations. He has been deeply involved in such areas as udder health, somat ic cell testing, dairy nutrition, stray voltage, and milking man agement. He developed countywide pro grams in mastitis control and nu trition and initiated the pilot proj- ect for a statewide somatic cell testing program. In 1984, he was named extension director for Double Aught Lumber broke all rec ords when they purchased milk from the Supreme Champion at the Troy Fair Milk Auction.

Guffey has extensive interna tional experience. He worked in Swaziland as a consultant to that country’s extension service in 1990. In 1994, he traveled to Szepietowo, Poland to teach and adapt Penn State programs for Polish extension specialists. He also worked with the Citizens Net work for Foreign Affairs to estab lish a viable dairy industry in the Hincesti region of Moldova in 1998. Guffey earned a bachelor’s de gree in dairy science in 1955 and a master’s degree in dairy manage- suits in a more rapid loss ol CO2 than usual Because more CO2 is bieathed out. there is less in the blood stream and consequently less CO2 is delivered to the shell gland The effects on eggshell quality arc immediate Highly productive hens tend to lay early in the day That means that most ot the eggshell forms during the night, over approxi matel> an 8-hour period Based on what is known about hen physiology, reducing heat stress specifically during the shell form ing hours is likely to result in the gieatest improvement in shell quality, provided that there is ade quate calcium intake Good ventilation in chicken houses will help carry away ex cess body heat ot the hens.

He also has continued post graduate studies and taken courses at Penn State, Cornell University, and Mansfield University of Penn sylvania. Guffey joined Penn State Co operative Extension as an assistant county agricultural agent in 1958. He was promoted to associate ex tension agent in 1963, reached the rank of extension agent in 1975, and became senior extension agent in 1982. Guffey lives in Towanda with his wife, Marilyn. The couple as two sons, Kenneth and David, and a daughter, Leah. They also have five grandchildren. Stephen Laudermilch holds his grand champion steer as the auction begins.
