    OCD: Selection and Health


    Note to expand on the information from ANCCE about the review of the X-ray protocol that is applicable for all TQBs.

    With regards to osteochondrosis, what ANCCE has done, is to upgrade the requirements concerning this disease, to adapt to the latest information on the topic.

    To do this, the association has contacted the most prestigious experts on this disease, professors Van Weerem, Novales and Jean-Marie Denoix. The conclusions they have presented show that there is no proof that osteochondrosis is genetically transmitted to the descendant, although there is a genetic predisposition in certain horses to have the disease.  In fact, it can appear in horses with no osteochondrosis in their family, but the opposite also occurs, some horses with a family history of osteochondrosis never develop the disease.  

    It has been proven that the management of the horses will have a major impact on the appearance of this disease; to avoid it, see the ANCCE web-site, in the news section, where professor Novales gives us some recommendations so as to prevent the appearance of osteochondrosis.

    Having revised the results obtained during the 2007 season, and following the criteria carried out in other countries, it has been decided to establish a radiographic classification of the lesions, adapted specifically for each anatomical structure that is the object of the study, only eliminating the most serious forms in the disease. These classifications pay more attention to the changes in the conformation of the bony contour, than to the presence of osteochondral fragments themselves (on the understanding that these may have been eliminated).
    For each anatomical structure, 3 grades will be established, depending on the seriousness of the lesions detected. Those horses presenting one grade 3 lesion or at least two grade 2 lesions in all of the anatomical structures examined, will be considered NOT APPROVED. With this, we are able to avoid discarding as qualified breeding stock, those individuals with proven quality conformation, without causing any reduction in the health of the breed, and to avoid possible damage to breeders.

    The proposed classification of osteochondrosis has been produced by the Reading Center (Manuel Novales), in conjunction with the members of the Counsel and Appeal Committee (Jorge de la Calle, Marta Prades and Miguel Valdés).  More detailed explanations, with graphic examples, along with more information about this disease, can be found on the website of the University of Cordoba Veterinarian Hospital Clinic, at www.uco.es/webuco/corporacion/hcv/osteocondrosis.php. The Hospital collaborates with ANCCE and acts as the radiological reading and interpretation center for OCD.
