D2-Lancaster Farming Saturday, February 18,1989 BY BONNIE BRECHBILL Franklin Co. Correspondent SHIPPENSBURG “There are five diseases that are an eco nomic threat to you,” Dr. Jerome Harness told farmers at the Memorial Lutheran Church on February 8. “The first two hemophilus and swine dysentery will put you out of business.” Harness, a Greencastle veter inarian who specializes in the care of swine, updated pork producers on five swine diseases at the Adams/Franklin/Cumberland Pork Producer’s meeting. The five diseases, along with their causes, predisposing factors, signs, diagnoses, treatments, and strategies for prevention are: Hemophilus • Caused- by bacteria. • Predisposing factors-carrier hogs, ventilation. • Signs-sudden death with no symptoms, mostly in grower and finishing pigs-not many under 60 pounds are stricken. • Diagnosis-lungs look bad in a necropsy (swine equivalent of an autopsy). The bacterium can be cultured. • Treatment-Dencgard in water, Naxel injections, LA 200 injec tions, Penicillin. • Prevention—be sure your source of feeder pigs is clean, depopulate, vaccinate, put antibio tics in feed. Swine Dysentery • Caused by bacteria. • Predisposing factors-occurs in 4-12 pound pigs, manure build up lack of sanitation, dogs and rodents are carriers, flies can carry it for four hours. • Signs--“ Gaunted” look, brown-red diarrhea, sudden death, off-feed. • Diagnosis-necropsy findings, microscopic exam, difficult to culture, • Treatment--Denegard in water, Lincomycin in feed-100 gm/Ton, Lincomycin in water, clean up, scrape down. • Prevention- be careful of your sources, avoid manure build up, BMD 250 gm/Ton, Denegard Timely Tips Offered For Swine Feed-Antibiotic Management LIVERPOOL, ENGLAND Mounting concern over drug residues and bacterial resistance in swine has prompted veterinarians, producers and feed dealers to take a second look at certain feed addi tives particularly those used in grower-finisher rations. Noting that some additives arc intended primarily for growth promotion and that others are best reserved for treating certain respiratory diseases, Dr. John R. Walton a well-known swine veterinarian at the University of Liverpool, England - has deve loped some useful guidelines for feed-antibiotic management. Following are what he calls the “Ten Commandments of a Growth-Promoting Antibiotic”: A grower-finisher antibiotic should... 1. Improve performance effec tively and economically. 2. Not cause cross resistance to other antimicrobials. 3. Not be involved with trans ferable drug resistance. 4. Not disturb the microflora of the normal gut --..for once dis turbed, pathogens can easily eptcr. 5. Have little_pr no therapeutic use in human or veterinary Swine Disease Could Put Farmers Out Of Business 35 gm/Ton, Lmcomycin 40 gm/ Ton, Mecadox to 75 pounds, depopulate, eradicate, vaccinate. Concerning the vaccination for swine dysentery, Dr. Harness said, “Those who sell the vaccine say it works. Those who test it say it doesn’t.” • Caused by bacteria. “Strep Suis is a great copycat,” Dr. Har ness said. “It can look like anything.” • Predisposing factors-- ventilation, carrier sows, young pigs. • Signs-Poor doers, cough, swollen joints, vulvar discharge, weight loss, nervous signs. • Diagnosis-necropsy sugges tive of it, easily cultured, sensitivi ty test is performed to determine which antibiotics will prevent the bacteria from growing. • Treatment-feed antibiotics, however, it is often seen in pigs that are too young to be eating feed. Other treatments arc penicil lin, terramycin, lincomycin, injections-penicillin, LA 200, Poly-Flex, amoxicillin, and lincomycin. • Prevention-early antibiotics, autogenous vaccine. • Caused by a virus. • Predisposing factors—time since the last outbreak, “If it has been four or five years since your last outbreak, then you’re due,” Harness said; time of year usually strikes between Christmas and Easter. This has been the worst year ever for TGE, accord ing to Harness, because he saw the disease all fall; carriers are birds and people. • Signs—vomiting and diarrhea, 1-4 days old, near 100 percent loss in young pigs. • Diagnosis-direct microscop ic examination on gut, send gut loops to special lab. ■ Treatment-nonc. • Prevention-commercial vac cines (effectiveness debatable), medicine. 6. Not be absorbed and remain in contact with the gut bacteria to produce the best effect and avoid tissue residues. 7. Not promote salmonella shedding. 8. Not be mutagenic or carcinogenic. 9. Not give rise to environmen tal pollution. 10. Be non-toxic to animals and human handlers - even at levels many times the normal use level. Dr. Walton, who will be louring CLARION A mcedng of state sportsmen/conscrvalion group leaders, selected legislators and the heads of the Pennsylvania Fish and Game Commissions has been called for March 4 to discuss how sportsmen can deal more effectively with the legislature and stale agencies. Sponsors of the meeting, the All Pennsylvania Sportsmen’s Rally, hope a network can be established among the various statewide organizations so they can coop erate with each other and deal with thc'lcgislature as one large sports men’s constituency rather than as Strep Suis Transmissable Gastroenteritis (TGE) Sportsmen homemade vaccines, pigs should have continuous access to sow, older sows tend to be immune, limit access to unit. Rota Virus • Caused by a virus. • Predisposing factors-poor sanitation in farrowing house, car rier sows, weaning brings it on, change to solid feed, gilt litter. • Signs—vomiting, mild diar rhea, post-wcanmg scours, 7-30 days of age, low mortality, “set back” for a few days. • Diagnosis-gut loop to special lab. • Trealment-none; could try control E-coli (secondary infec tion), support pigs, give good nursing care. • Prevention-dry-clean-draft free environment, vaccinate, natural vaccination, manure feed back, older sows apt to be immune. Public Speaking Contest To Be Held At National Junior Angus Show ST. JOSEPH. MO The American Angus Association will sponsor its first ever national Public Speaking Contest during the 1989 National Junior Angus Show and Showmanship Contest, July 18-20 in Louisville, Kentucky. “Communication is an abso lutely vital element in our socie ty,” said Mark Wyble, director of junior activities for the American Angus Association. “The ability to communicate effectively is not only an art, but can mean the dif ference between success and or failure.” In an effort to foster the deve lopment of speaking skills among National Junior Angus Associa tion (NJAA) members, the Ameri can Angus Association and the NJAA Board of Directors will sponsor this national public speak ing contest for NJAA members. Some of the regulations for the contest are as follows, junior the USA this year and speaking at several industry meetings, urges producers, veterinarians and feed dealers to work more closely together in selecting feed additives. He also notes that rotating cer tain feed antibiotics in the grower finisher phase for example, feeding BMD for three weeks, CTC for one week - will help to reduce costs and improve the activity of tetracyclines.

Dead bird disposal continues to be a concern. Researchers at the Uni versity of Delaware developed a composting system for disposing dead birds, and attendees will hear about the system. In addition, they’ll hear how computers are assisting management in layer and broiler houses. Other topics include future lifestyle trends that will affect the poultry industry, poultry facilities at Penn State, the national survey conducted for egg producers, and poultry health.

Male cattle under six months of age from herds known to be affected would continue to move interstate in accordance with the current regulations. Under the proposal, female cattle and test eligible male cattle originating in Class C states or areas which are not brucellosis exposed and are from herds not known to be affected would be allowed to move interstate to recognized slaughtering establishments and quarantined feedlots only. All other interstate movement of these cattle from Class C states or areas would be allowed only if they originate in certified brucellosis free herds. These restrictions are effective as of February 17, 1989. For more information contact Dr. Hugh E. Metcalf, senior veter inary medical officer, Animal and Depredation Management Sys tems, Program and Policy Deve lopment, APHIS-USDA. Phone: (301) 436-8499. (Federal Regis ter, January 18, 1989)
