ABSTRACT
As follows from the population statistical investigation performed within the management information system, defects of the anatomic structure of the feet occur in the pig population of all breeds and cross combinations kept in the Czech Socialist Republic the frequency of this occurrence is relatively higher than 4.4% (1984) and 3.8% (1985) of all litters affected by some of the genetic defects. In some populations different degrees of claw asymmetry occur in more than 40% of the individuals. Environmental conditions contribute to the severity of the defect (technology, particularly the type of floor), but the disposition is genetically conditioned. Prevention should mainly be based on the negative selection of the carriers of the undesired disposition. Working on this study, we used the results of the population statistical processing of the reports on the hereditary defects of pigs and the results of our own observations. In the former case the data concerned 29,778 pig litters, in the latter case 7343 pigs of the Large White, Landrace, Duroc and Prestice Black-Pied breeds.
