Breeding Shed Information - Listing of Imported Mares
Below is a link to open the listing of thoroughbred mares imported from CEM affected countries since June 1, 2022. Please remember that before these mares are bred you should receive a copy of the "Quarantine Release" - and if not included on the Quarantine Release - a copy of the CEM culture collected from the endometrium, indicating they have satisfactorily completed the CEM testing procedure. Each of these mares are to be bred last in the session.
In addition, remember that "MAIDEN MARES or MARES IMPORTED FROM NON-CEM AFFECTED COUNTRIES" ARE NOT INCLUDED ON THIS LIST. It is the breeding shed's responsibility to identify these mares when they are booked, and to insure that the proper testing has been satisfactorily completed. They need 2 sets swabs collected and cultured negative for CEM. A swab shall be collected from the endometrium and cultured for CEM. This swab may be included with either of the required sets of swabs, or in the case of a pregnant mare, this swab may be collected after foaling. These mares are to be prophylactically scrubbed and are bred last in the session.
Also, please remember to notify the State Veterinarian's Office whenever an imported mare is covered by one of your stallions. We need the name of the covering stallion, breeding date, imported mare's name and boarding farm including the correct mailing address. In addition, we need the same information for the next three mares covered by the same stallion.

Contagious Equine MetritisImportation Program - History and Guidelines of Program
Kentucky is approved by the USDA to accept both mares and stallions from countries considered by the USDA as being affected with Contagious Equine Metritis (CEM). We accept and clear from quarantine in excess of 300 mares and 25 stallions here in Kentucky annually. During the course of the quarantine the animal undergoes a series of tests and treatments to determine that the animal is not infected with CEM. All of the work done on the animal during the quarantine is performed under the supervision of a representative from the Department of Agriculture by a private practitioner who is licensed and accredited to practice in Kentucky.
In the past, the length of the quarantine varied with each mare. Non pregnant mares most often were cleared and released from the quarantine in as little as 35 days. Pregnant mares however remained quarantined until a final set of cultures were obtained post foaling. Recent changes in the regulations now make it possible for all mares to complete the prescribed testing and treatments in as little as three (3) weeks. With regard to the male animal; again all work is performed under the supervision of the Department of Agriculture by a private practitioner. In the past, the quarantine period on stallions was approximately 55 days. Again, the prescribed testing and treatment requirements were changed and now stallions can be completed in as little as 38 days. In order to determine that the stallion is not infected with CEM the animal is bred to two (2) mares and the mares are then subsequently tested for the detection of CEM bacteria.
Kentucky is unique in that it is the only state we know of which requires some degree of CEM testing on all equine animals which have ever been in any foreign country (Canada is sole exception) for any purpose after the animal reached 731 days of age. This testing must be completed before the animal is permitted entry into a breeding shed or facility. Any stallion wishing to stand at stud in Kentucky, which has been outside of the United States (except for Canada) is required to undergo the test breeding procedure. Again this takes about 38 days to complete. Any mare (even maiden fillies) which has been outside of the United States (except for Canada) are required to have a minimum of two (2) sets of cultures before being eligible to be bred in Kentucky. This procedure takes no fewer than ten (10) days.

|KENTUCKY CEM IMPORTATION PROGRAM STATISTICS|
EQUINE IMPORTS - EQUINE FROM NON-CEM COUNTRIES
Imported Equine Not Quarantined Upon Arrival Includes:
1) Equine from non-CEM affected countries
2) Equine less than 731 days of age at the time of importation
3) Thoroughbred horses from England, Ireland or France which are certified as having not been on a breeding premise since reaching 731 days of age
The following information indicates the number of equine imported into Kentucky for the period 1992 thru 2004 which were not required by the USDA's Federal Code of Regulations to be quarantined and successfully complete the CEM testing and treatment requirements upon their arrival in Kentucky.
Our own State Administrative Regulations do require the successful completion of Prescribed CEM Tests before the animal is eligible to be bred: Follow this link for an outline of the testing requirements for FEMALES or MALES
NOTE: 2009/2010 data is 'Incomplete' and does not include all horses imported into Kentucky through the Miami Animal Import Center. *Includes 447 horses imported in 2010 through the Temporary CVG Facility for horses imported to participate at WEG. (Updated 03/01/2012)
