C2-Lancaster Farming, Saturday, February 6, 1993 -1 Pennsylvania PRV HEADLINES / A bi-weekly communication from PA Pseudorabies Committee and Penn State Extension to alert you to developments in PRV and its control PSEUDORABIES BETWEEN-FARM SPREAD Timothy P. Trayer, DVM Veterinary Practitioner Denver, Pa. The primary method of spread of pseudorabies is still pig-to-pig. The key to control exposure of your farm to pseudorabies (PR) is to maintain a well thought-out plan of animal movement on and off your farm. The infected pig is still the largest single source of pseudo rabies virus (PRV). When new herd replacements come to the farm, they should be placed in an isolation facility that houses these animals away from the main herd. They should remain there for 21 to 30 days. During iso lation, these animals should be tested for disease and vaccinated. No matter how good the boar next door, dont bring him to your farm to service your sows.

Dedi cate one truck to the movement of animals within your farm. Never use the same truck to haul market or cull animals and nursery or grower pigs between facilities on the farm. Trucks and trailers that are used to haul pigs off the farm should be cleaned and disin fected before coming back to the farm. Never allow a partial load of pigs from another farm to come to your farm. Try not to borrow from or loan equipment to another farm. If this becomes necessary, clean and dis infect the equipment and let it stand for three days. Swine should not have access for two days to pastures which were recently spread with manure.

Certain geographical and climatic condi tions must be considered as well as the swine density in the area and the swine population that is not vaccinated and has a low resis tance to PR. Producers need to keep in tune with the PR status in their area. Be cooperative with the surveillance program being conducted by the state and U.S. Department of Agri culture. Vaccinate for PR if other PR farms are within two miles of your farm. Strengthen your on-farm biosc curity and continue your off-farm biosecurity. Knowing the neigh borhood disease status will help in making testing and vaccination decisions. Unless delivery trucks have Attendance At ANNAPOLIS, Md. Mary land Secretary of Agriculture Robert L. Walker has announced that attendance at agricultural fairs in Maryland during 1992 totaled 2,230,015 people. These figures come from the Maryland Agricultural Fair Board which, since its inception in 1937, has promoted Maryland’s largest industry agriculture by pro viding financial assistance to agri cultural fairs, shows, and youth activities throughout the state. “In 1991 and 1992 we topped 2 million people each year. I think these attendance figures demons trate that Maryland’s agricultural fairs continue to prosper and attract huge interest.

Check for manure contamination of deliv ered grain. Organic material, like hog manure or feed, can harbor PR virus for four days. Therefore, pur chased grain should be stored for a minimum of four days before it is fed to pigs. Do not use the same truck to haul livestock and feed. In central Pennsylvania, producers rarely use the same vehicle to haul pigs and feed. Any grain imported from the Midwest has a storage and transit time which usually exceeds four days. People should be considered a source of disease spread. Manure can be carried between groups of Tops 2 dynamic nature of Maryland’s agricultural industry,” Walker said. “As somebody from the city, I appreciate, as do thousands of our citizens, the county fairs that allow us to leam about the tre mendous agricultural bounty of Maryland. I enjoy these fairs because they bring people together to share experiences, skills, and fun,” said Maryland Governor William Donald Classified ads! fe. PAY OFF[ J| s '\ * pigs on shoes and clothing. Do not let people wander through your facilities. When people come to your farm, insist that they wear clean clothing or coveralls and dis infected rubber boots or disposable plastic boots. A supply of plastic boots can be purchased from a farm supply store and kept on hand. The key to keep PR from spreading to your farm is to man age the whole system. Key areas to control are the swine, their manure and manure from other sources, the source of your feed, and people who visit your farm. Consider vac cinating your pigs to reduce the chance of PR infection through the air from neighboring infected farms. Ag Md. Million Schaefer.
