DMtncwter Farming Saturday, May 27, 1989 Parasite Compounds Every few years we’re fortunate to have a few more safe and effec tive compounds available to help producers control parasites on their operations. In order to help producers compare the character istics of these compounds. I’ve compiled a list of the widely used materials. EXTERNAL PARASITES Mange Control Mange is caused by a mite that burrows under the skin, causing itching and restlessness in the pig. Studies show that mange can impair feed efficiency in growing pigs by more than 10 percent, and can decrease baby pig survival by .6 pig/litter. Under field condi tions, it’s been demonstrated that the annual cost of mange is $BO per sow. Effective mange control com pounds include Permectrin and Ectiban (permethrins, spray). Pro late (organophosphate, spray), iTaktic (amitraz, spray) and Ivomec (ivermectin, injectable). Here arc some characteristics and approximate costs for each of these compounds: PERMECTRIN, ECTIBAN No age restrictions. S day with drawal. High pressure required (100 - 200 PSI). 2 applications necessary (7 -10 days apart). $lB.OO - 37.00 for 50 gallons. The $37.00 cost is associated with a high concentration of per methrin that may be needed when sows or pigs are badly infested. For normal control, a 50 gallon batch will cost about $lB.OO. PROLATE Can not be used on pigs under 3 months of age. 1 day withdrawal. High pressure required (100 - 200 PSI). 2 applications necessary (7 -10 days apart). $23.00 for 50 gallons. TAKTIC No age restrictions. 1 day withdrawal. Partially system ic. Low pressure adequate due to systemic action (minimum 35 PSI). 2 applications necessary (7 -10 days apart). $33.00 for 50 gallons. While Taktic is more expensive than the other sprays, it has the distinct advantage of being par tially systemic. That means the active ingredient is absorbed into the bloodstream of the pig, and also means that lower pressure can be used, and the entire pig does not need to be soaked. IVOMEC No age restrictions. 18 day withdrawal. Must be injected under the skin. 1 applica tion will provide good control with no further exposure. $.BO per 100 lb pig ($32 for 40 pigs). The SO gallons of spray calcu lated for the previous compounds would be cnough to treat at least 100 pigs. Ivomcc is clearly the duct on the market, but it does require injection, and it is more expensive. When used as a control measure for both internal and external parasites, the economics get a lot more attractive for Ivomec. No matter what compound your choose, remember that for good mange control, sows, should be treated 10 days before farrowing. Pigs should be treated shortly after weaning. Lice Control Lice are insects about an 1/8, of an inch long. They’re often found behind the ears, especially in mature swine. Lice cause itching, but they do not make pigs as uncomfortable as mange. Any product that is effective against mange will also control lice. In addition, one compound that’s labeled only for lice is Tigu vdn (fenthion, pour on). Here are the characteristics and approxi mate cost Tiguvon; TIGUVON Pour on 1/2 oz/100 lbs of body weight Can be used on lactating sows. 14 day with drawal. $.lO per 100 lb pig ($32 for 320 pigs). Tiguvon is very effective against lice. It’s systemic and the compound remains in the system long enough that one application is sufficient provided pigs are not re-exposed. INTERNAL PARASITES Worms cost swine producers money by damaging the liver and lungs of pigs, obstructing the digestive tract, competing for nutrients and adding to the pig’s discomfort Infestation of pigs less than 100 pounds causes the great est economic losses. The worms that affect Pennsylvania include the large roundworm, the nodular worm, the whipworm and the lungworm. Pigs become infected with large roundworms by consuming eggs in the pen. The eggs hatch in the small intestine. Larvae then cause damage as they migrate through the liver and lungs, and are finally coughed up and swallowed. Once back in the intestinal tract, the lar vae grow to adults. The life cycle of the nodular worm and whip worm is similar, except that larvae do not migrate through the liver and lungs. With the lungworm, eggs are eaten by earthworms, which are then consumed by the pig. Larvae eventually pass into the lungs. The lungworm is the only internal parasite that will not be a problem in confinement Effective compounds for con trolling internal parasites include Atgard (feed grade, dichlorvos), Tramisol (levamisole, feed grade or water). Safeguard (fenbenda zole, feed grade), Banmiqth (pyr antel tartrate, feed grade), and Ivomcc (ivermectin, injectable). New Officers Elected At Virginia Angus Meeting ST. JOSEPH, MO Some 130 members were in attendance for the Virginia Angus Association annual meeting and banquet, and they elected a new slate of officers for the coming year. The event was held at Charlottesville. Elected president of the group was John Pyne, Culpeper. Roger Steele, Troutville, was selected vice president and Tom Temple ton, Charlottesville, will stay on as executive secretary. Four new directors were voted to the board. They are Ken Barn hart, Purcellville; Roger Bowles, Kents Store; Newbill Miller, Washington; and Tom Stokes, Uppcrville. There were several awards pre sented to Virginia Angus mem bers during the banquet. The 1989 state handbook was dedicated to Robert Deputy, Mount Crawford. Northcote Farm, Forest, was hon ored with the Arthur V. Bartensla gcr Award. The 1988 Virginia Angus Family of the Year trophy went to the Fritz Friant Family of Hayes. Junior member Anne Jones, Forest, was the recipient of several awards. She was presented the Ayrshire Challenge Trophy and the Outstanding Senior Award, and was named the Premier Senior Exhibitor for 1988. Neenah Hill of Forest was awarded the Premier Junior Exhibitor plaque and the Outstanding Junior Award went to William Fcdcrspiel, Powhatan. Jason Michael, Mt. Solon, was honored with the Novice Award. Patty Simpson of Buchanan was also honored at this time. She was crowned the 1989 Virginia Angus Queen. -iig us jiation Elected new officers.

Saturday, June 3, will find many people all over Pennsylvani a converging on the Cambria County fairgrounds, Ebensburg. The program, beginning at 8:30 a.m. at the Agricultural Building at the fairgrounds, will be of inter est to all who are engaged in or plan to raise rabbits. Registration fee is $lO for adults, 16 and over, and free for those under 16. The program in the morning will include a discussion of pre vention or control of major health disorders by Dr. David Kradcl, Veterinarian, Penn State; a prog left, Tom Templeton, executive secretary; John Pyne, presT dent; Rogr St vii member am) pnhttteV Senior exhibitor of the Virginia Junior Angus Association. Presenting the award was Tom Templet ton, association executive secret by Dr. Owen Keene and Herbert Jordan, both of Penn State; and a discussion and demonstration on how to prepare a rabbit for show by Dale Gearhart, rabbit breeder and judge, of Hollidaysburg, Pa. After lunch there will be a panel of local rabbit 4-H leaders and loc al rabbit breeders discussing how they manage rabbits in their situa tion. This will j» chaired by Don Shirk, Vintondale, and will include: George Myers, Bames boro; John Oravec, Nanty Glo; and Roger Clark, Belsano. Larry Yager of ag economics at Penn State Extension wiH talk about developing market*, arid discuss rabbit breeding. There will be a brief discussion of the Pennsylvania Rabbit Breed ers’ Association by Linda Claarof Woodward, president of the group. This is an'affiliate of the American Rabbit Breeders’ Association. There will then be an evening meal at the United Methodist Church in Ebensburg, and the day will finish back at the fairgrounds with a “Rare Rabbit Show.’’ If you want a program or an application call or write die Exten sion Office in Ebensburg ■ phonej Courthouse Extension 392 or loc^
