Stray Voltage And Dairy Farms Conference Coming To Camp Hill CAMP HILL (Cumberland Co.) “Stray Voltage and Dairy Farms: A Conference for Farm Advisors, Educators, Utilities, and Public Policy Advisors,” will take place April 9-11, in Camp Hill. Experts from Wisconsin, Mich igan, Nebraska, New York, Ari zona, Ohio, Vermont, and Cana da will share their experience and answer questions at this unique event. University, state govern ment, utility, and industry per spectives are included. The con ference is sponsored by NRAES, the Natural Resource, Agricul ture, and Engineering Service. Stray voltage is defined by the USDA as “a difference in voltage between two surfaces that may be contacted simultaneously by an animal.” When this occurs, the cow acts to complete the circuit and experiences a small shock or BASKET FANS 1/2 Hp, 24” & 1/2 Hp, 36” Quantity Pricing Available Highest Airflow - Lowest Energy Cost Advantage™ offers • Airfoil propellers with stall-limiting design propeller diameter • High impact polymer housing . ff f* . >*- *'•* • Tapered and extended r&' " cone improves efficiency Aerotech® offers you a Lifetime Warranty on the propeller, housing and cone. housing • State-of-the-art shutter 76“ Vortex . design Belt Drive and Direct Drive GALVANIZED FANS Economical line of galvanized fans are now available in various versions to fit any need or application that you may encounter Direct Drive • High efficiency “PSC” motor • Full variable speed capabilities • Upright motor mounts for unrestricted airflow Available in 36” & 50” sizes • High quality sealed “AVS” designed bearings • V Belt with belt tensioner “tingle.” Research shows that stray voltage may increase cow stress and health problems. Sometimes, however, problems attributed to stray voltage are in fact caused by something else, and a multidisciplinary team is needed to identify the actual problem. The conference will begin with an overview of electricity and wiring fundamentals to ensure that everyone has the back ground necessary to understand the more technical presentations that follow. Specific objectives of the conference are to: • provide an overview of the fundamentals of electricity, power distribution, and farm and home wiring systems; • present research accom plished since the 1991 publication of Effects of Electrical Voltage/ Current on Farm Animals: How With Cord and Ceiling Mounting Brackets. 1/3 Hp, 24”, Vortex™ offers • Cast aluminum 3-blade airfoil propeller • 26” and 51” propeller diameter • Streamlined fiberglass & Fan Belt Drive BARNSTORMER FANS Air Circulated at Its Best.

The “Stray Voltage and Dairy Farms” conference is being coor dinated by NRAES, the Natural Resource, Agriculture, and Engi jSSSutitSSSSnS neering Service The registration fee is $3lO after March 25 or at the door. The fee includes one conference admission, an evening reception, one lunch, break re freshments, and a copy of the conference proceedings. See NRAES contact information below. The conference will take place at the Radisson Penn Harris Hotel and Convention Center in Camp Hill. Two Dairy Workshops Planned In Lancaster County LANCASTER (Lancaster Co.) Two workshops will be conducted in Lancaster County for dairy farmers, nutritionists, and industry per sons interested in improving transition cow health and nutrient man agement for their dairy herd. The first workshop will take place April 8 at the Lancaster Farm and Home Center and the second April 15 at the Lancaster DHIA lab, Manheim. The sessions will run from 10 a.m.-2 p.m. Speakers will include Dr. Les Lanyon from the department of Crop and Soil Sciences; Dr. Robert VanSaun from Veterinary Sciences, and Dr. Zhiguo Wu of the Department of Dairy and Animal Science. Two nutrient management continuing education credits will be offered for attending this workshop. The following topics will be covered; • Transition cow health: Potassium metabolism, downer cow prob lems, milk fever prevention; flowchart for diagnosing and correcting transition cow disorders. • Forage management for transition cow health: Crop potassium uptake and content; tools for monitoring farm potassium status and reducing forage potassium content. • Dairy phosphorus: Reduce ration phosphorus for better transi tion cow health, less manure phosphorus, and lower feed costs. The cost for each workshop is $lO, payable at the door, which will include lunch. To register, call the Lancaster County Extension office at (717) 394-6851, or send name and address to Beth Grove, Lancaster County Extension, 1383 Arcadia Road, Room 1, Lancaster, PA 17601. 2003 Red Angus EPDs Available DENTON, Texas The 2003 Spring Red Angus EPDs are now available. The Red Angus Association of America (RAAA) publishes EPDs for growth, female fertility, and carcass traits which include genetic predictions for birth weight, weaning weight, yearling weight, milk, total maternal, calving ease direct, heifer pregnancy, calving ease total maternal, stayability, marbling, ribeye area, and back fat. Red Angus carcass EPDs are available on over 340,000 head. This industry-leading program has successfully incorporated both tradi tional carcass data and real time ultrasound into the calculation of the genetic predictions for carcass merit. The new EPDs are from the Spring 2003 Red Angus National Cat tle Evaluation conducted at Colorado State University. The EPDs are available on the web at www.redangus.org.
