All of the bacterial and viral venereal diseases which may be transmitted during natural mating can also be transmitted in artificially inseminated semen, be it fresh, chilled or frozen. Owing to the large number of mares that can be inseminated by an infected stallion and the fact that the diseases are endemic in many countries from which semen may be imported, the potential for disease transmission via the use of artificially inseminated semen is significant. It is
therefore essential that all semen is accompanied by certification provided by the sender confirming the disease free status of the stallion at the time of collection. It is also essential that no semen is artificially inseminated unless the
person performing the insemination can verify the following:

I. For semen originating within the UK (fresh, chilled or frozen)

A. Each dose of semen must be clearly labelled with:

  1. The name of the stallion;

  2. The time and date on which the semen was collected;

  3. The insemination dose per mare;

  4. The progressive motility of the semen;

  5. The concentration of the (extended) semen.

B. Each dose of semen must be accompanied by a certificate available to download here , stating that:

  1. The stallion has been tested for the CEMO, Klebsiella pneumoniae capsule types 1, 2 and 5, Pseudomonas aeruginosa and equine infectious anaemia according to the current HBLB Code of Practice, with negative results after 1st January of the current year.

  2. The stallion has either been tested seronegative for Equine Arteritis Virus according to the current HBLB Code of Practice after 1st January of the current year or has been vaccinated against EVA having been tested seronegative prior to vaccination or has been tested seropositive, is not vaccinated against EVA but has been proven by virus isolation test not to be shedding the Equine Arteritis Virus in his semen.

II. For semen originating outside the UK (fresh, chilled or frozen)

A. Each dose of semen must be clearly labelled with:

  1. The name of the stallion;

  2. The time and date on which the semen was collected;

  3. The insemination dose per mare;

  4. The progressive motility of the semen;

  5. The concentration of the (extended) semen.

B. Each and every consignment of semen being imported into the UK from within the EU must be accompanied by a completed intra-community trade certificate (INTRA), specifying the name of the stallion whose semen the certificate relates to and by an original, valid health certificate issued in the country of origin.

C. Each and every consignment of semen being imported into the UK from outside the EU must be accompanied by a completed Common Veterinary Entry Document (CVEDA) and by an original, valid health certificate issued in the
country of origin.

D. It is an option to have a shipment of chilled semen tested by PCR if there is any doubt about its status. Laboratories approved for testing by PCR are listed here. This does not substitute for the correct paperwork accompanying the shipment, which will still be required.

Use of artificial insemination is not permitted where the progeny is to be registered with the Weatherbys General Stud Book. However, disease spread via AI has the potential to impact on Thoroughbred breeding operations through
Thoroughbred/non-Thoroughbred cross breeding.
