Manitowoc County 4-H Horse Project

Having fun & learning...one ride at a time

Text Box: Horse Health

All horses & ponies must have a negative current year Coggins test. Your original and a copy are required at all horse events. Without a negative Coggins test and copy, you will not be allowed to unload your horse!

Negative Coggins Test

Horses and ponies are required to be vaccinated. The four-in-one vaccination includes: Tetanus, Eastern and Western Equine Encephalomyelitis, and Equine Influenza. We also recommend Rhinopneumonitis. (Young animals will also need to show the second booster shot on the proof of vaccination.) Vaccinations must be administered prior to participating in any 4-H event as well as the Manitowoc County Fair.

 

Proof of vaccination consists of one of the following:

· Dated receipt/signature of person administering shot

· Dated/signed Certificate of Vaccination (veterinarian)

· Copy of dated/signed receipt from your veterinarian

Wisconsin Horses Quarantined, Will Be Tested After Exposure to Reproductive Disease

Contact:  Donna Gilson 608-224-5130

 

MADISON - Seventeen horses on 11 different farms in Wisconsin have been quarantined and will be tested because they have been exposed to a highly contagious disease that can cause reproductive problems in mares.

However, Wisconsin State Veterinarian Dr. Robert Ehlenfeldt of the Wisconsin Department of Agriculture, Trade and Consumer Protection said there is no risk to horses in the general population, and no human health risk.

Most of the horses are mares that were bred either naturally or by artificial insemination to one of seven stallions that have tested positive for contagious equine metritis, or CEM, in other states. The quarantine means the horses cannot leave their farms without department approval, and must be isolated from non-quarantined horses until they test negative.  This is a process that may take several weeks or even months, Ehlenfeldt said.

The Wisconsin quarantines are part of an investigation that involves at least 250 horses in 27 states, according to the U.S. Department of Agriculture.  The investigation began in mid-December, when a quarter horse stallion on a Kentucky farm tested positive for the venereal disease during routine testing for international semen shipment. Ultimately, three more stallions in Kentucky and three in Indiana that had spent time on the original farm also tested positive.

"There is no risk to horses in the general population," Ehlenfeldt emphasized.  "The risk is limited to horses that had some exposure to the infected stallions, either by breeding or being in the same facility and sharing equipment.  It is possible that as the trace continues, we'll be notified of other Wisconsin horses that were exposed, but we've contacted the owners of all the exposed horses we are aware of.  If you're a horse owner and you haven’t heard from us, it's unlikely that you will."

CEM is a highly contagious bacterial infection that passes between mares and stallion during mating or in semen used in artificial insemination.  It can also be transmitted on contaminated insemination equipment. Stallions do not suffer any symptoms, but the infection causes inflammation in the mare's uterine lining.  This may prevent pregnancy or cause the mare to abort if she becomes pregnant.  It is treatable. The disease was first reported in 1977 in Great Britain, and was found only twice previously in the United States:  in 1979 and in 2006, when three Lipizzaner stallions imported into Wisconsin from eastern Europe tested positive after their arrival.  The infection was discovered before they had been used for breeding.

More than 20,500 premises with horses are registered in Wisconsin. Although the state is not a big player in the international equine export market, the USDA said that this outbreak could threaten the nation's $415 million annual trade in exporting horses, semen and embryos. Movement restrictions, tracebacks, and increased testing could result in added costs both to owners and to public agencies.

Ehlenfeldt said, "The main thing is for horse owners to be aware that the disease is out there and as always, good biosecurity is the best medicine. Breeders need to understand that, too, and be sure to clean and disinfect AI equipment thoroughly between uses."

Second Wisconsin Stallion Is C.E.M.-Positive; Found In Trace From Previous Case

MADISON - A second stallion quarantined in Outagamie County has tested positive for contagious equine metritis, or CEM, a treatable reproductive disease of horses.

The National Veterinary Services Laboratories in Ames, Iowa, reported the positive test result Thursday afternoon, Jan. 22.  The stallion, a 4-year-old Paint, has been quarantined since Jan. 16, when state animal health authorities learned he had been at a Wisconsin artificial insemination center at the same time as another infected stallion from Outagamie County.

He was one of 18 stallions quarantined because they had been exposed to that earlier reported CEM-positive stallion in Outagamie County.  All are located in Wisconsin.  In addition, 29 exposed mares are quarantined in Wisconsin because they have been exposed to CEM-positive stallions.

State and federal animal health personnel will examine the newly identified stallion's breeding records and movement history to trace what mares may have been exposed via natural breeding or artificial insemination, and what stallions may have been exposed via shared artificial insemination equipment.

Any exposed animals, in Wisconsin or other states, will be quarantined for testing. Wisconsin owners of exposed animals will be contacted by the Department of Agriculture, Trade and Consumer Protection.  For those in other states, the department will notify those states' animal health authorities, who will contact owners.

There is no human health risk and no risk to horses in the general population.

Nationwide, the CEM investigation now involves at least 383 horses in 42 states, according to the U.S. Department of Agriculture.  The outbreak began in mid-December, when a quarter horse stallion on a Kentucky farm tested positive during routine testing for international semen shipment.

CEM is a contagious bacterial infection that passes between mares and stallions during mating.  It can also be transmitted on contaminated insemination equipment. Stallions do not suffer any symptoms, but the infection causes inflammation in the mare’s uterine lining.  This may prevent pregnancy or cause the mare to abort if she becomes pregnant.  The disease is treatable with disinfectants and antibiotics.

CEM is considered a foreign animal disease in the United States. It was first discovered in Europe in 1977, and has appeared in the United States only twice outside quarantine stations where stallions are required to be tested and treated before being released into the country.  In 1979, there was an outbreak.  In 2006, three Lipizzaner stallions imported into Wisconsin from Eastern Europe tested positive after their arrival, but before they had been used for breeding.
