The rate of inbreeding per generation (5.2%) exceeds the 1% (0.01) maximum limit defined by FAO. Taking into account only the living population, roughly 97% of the animals showed F≥25% (some of them exhibiting values above 60%), and there were no cases with AR values lower than 50%. The average F, AR and mean kinship coefficients computed for this group were 36.90%, 55.11% and 0.34, respectively. Indicating high losses of genetic diversity through generations, great differences were found for the genetic contribution of each founder to the current genetic pool and some of these animals are no longer represented.
