E4-Boarder& Trainer, Lancaster Farming, Saturday, May 10, 2003 Regular Testing Ensures Health At The Sale Bam MICHELLE KUNJAPPU Lancaster Farming Staff NEW HOLLAND (Lancas ter Co.) In only a short time on a typical Monday, Dr. Jim Holt may press a stethoscope to a horse’s side, stop to an swer a horse owner’s question, consult his clipboard to search for a number, answer the phone, and consult his clip board again. Finding a number not cross ed off, he’ll begin again a search for a horse in be tween answering more ques tions or checking results at the laboratory on the premises. A veterinarian who works at New Holland Sales Stables every Monday, Holt is in charge of administering the Lab technician Carol Stevens runs two Coggins tests in the laboratory. Here she prepares for the agar test, which takes 24-48 hours to run. Although most of his job is administering Coggins tests, Holt may also evaluate horses for illnesses, such as this pony. Coggins test to horses sold at the auction. Holt also checks horses to decide whether they are legal to sell. He checks body condi tion and evaluates lameness, wounds, blindness in both eyes, and debilitating diseases. “Essentially what we’re try ing to do is interpret Pennsyl vania’s animal cruelty law,” said Holt. “Things have improved dramatically at the sale bam in the last several years,” he said. “We don’t see the prob lematic horses as frequently.” Also the relationship be tween the SPCA and the sale barn has improved, according to Holt. In the spring, 200-300 horses may be auctioned off every Monday. Holt and Jiis assistants administer the Coggins test to 40-100 of those horses. This re quires drawing blood, as Holt demonstrates here. “Although people may be lieve that this is a slaughter only sale, on average 10 per cent or less of the horses go to slaughter,” he said. Testing For EIA Mandatory for horses com ing to the auction from out side of Pennsylvania, the test is for equine infectious anemia (EIA), a viral disease. Penn sylvania does not require Cog gins testing qn in-state horse transactions. Owners of horses coming in from outside of Pennsylvania are responsible, if their horse has not already been tested, to have the horse Coggins tested at the sales stable. Owners of a newly-pur chased horse may also opt to pay the $2O to have their horse tested, since the test is required, for example, to par ticipate in shows. They can find out results in two hours. The ELISA test is run in batches. Stevens can test from one sample to “as many as I can keep track of,’* she said. Although EIA “is not com mon compared to the number of tests that we run,” accord ing to Holt, “there is no vac cine and there is no treat ment,” so the test is important. However, “we’ve only had two positives since we started the lab three years ago,” he said. Biting insects usually flies spread the disease, in addition to a needle used on an infected horse and then used on an uninfected animal. Holt arrives at the sale bam a half hour before the sale starts to go through the list of horses consigned “to decide who needs tested and who doesn’t,” he said. Arriving early also allows him to “go through while the horses are somewhat statio nary,” although with horses continually being checked in or taken through the ring, finding the horses on his list is a challenge. In the spring, 200-300 horses may be auctioned off every Monday. Holt and his assistants may test 40-100 of those horses. Technician Amber Wiedler also helps to find the horses and draw blood. Paperwork for each horse includes re cording the horse’s number, breed, age, sex, and markings. In The Lab Lab technician Carol Ste vens runs two different Cog gins tests in the laboratory lo cated on sales stable grounds. The ELISA test results are ready in only hours, while the agar test takes 24-48 hours to run. Stevens runs the Enzyme Linked Immunosorbent Assay (ELISA) test on most of the samples. However horses going to New Jersey, which does not accept ELISA test re sults, are given the agar test. According to Stevens, “the ELISA test takes a very small amount of serum,” which is separated from the blood sam ples by a centrifuge. This al lows Stevens to test the serum which rises to the top. Although approximately 70 percent of his job is adminis tering the Coggins test, Holt may also examine horses as they are checked in to the sale bam for possible problems. He also may evaluate horses that have already been sold, since a horse may be resold “if the owner finds something they can’t live with,” he said. Holt is part of Brandywine Veterinary Services, a four veterinarian practice based in Coatesville. He also works with the dairy cattle at New Holland Sales Stables on Tuesdays and Wednesdays.
