Frequencies of deleterus character in the spanish water dog affecting the breed conservation

摘要

321 puppies of the Spanish Water Dog Breed have been used to study the frequency of presentation of several deleterious characters between the years 1995 and 1998. The enogmatism and the monorquidism shown frequencies relatively low, but we stand outthese characters because their control is very important for the relationship with respect the adaptive capacity of these animals. In the same way the prognatism and the absence of premolars were present with a frequency slightly high, it must take intoaccount in the selection criteria of the breed. By another side, we found a signifficative association between the presence of heath anomalies and slightly high populational levels of inbreeding, and then we have to avoid these breeding practices in theracial lines presenting this defect.
