Abstract
A 4-day-old male Martina Franca donkey foal was evaluated for a forelimb alteration.Clinical examination and radiographs revealed the agenesia of the distal digit.Biochemical parameters were normal, and ultrasonographic evaluation did not identifyany relievable organ alteration. Karyotype study revealed an abnormality on chromosome1. The foal was discharged with a distal limb bandage in which a palmar splint wasapplied. A poor prognosis for the functionality of the limb was given. In endangeredspecies, such as the Martina Franca donkey, the excessive inbreeding could result in anincrease in genetic disorders. These findings shed new light on the possible pathogenesisof the digital dysgenesia. The study of the karyotype could be a useful approach to detectgenetic alterations that could or could not be expressed in the animal, especially inendangered species in which a risk of an excessive inbreeding is considerable.
