MARTINEZ, M.; ARMSTRONG, E.; GAGLIARDI, R.  and  LLAMBI, S.. Pedigree analysis of the canine breed Cimarron Uruguayo. Arch. zootec. [online]. 2011, vol.60, n.232, pp.1327-1330. ISSN 1885-4494.

In order to assess the genetic variability of the Cimarron Uruguayo dog breed, we analyzed all the available pedigree records (n= 6079) using ENDOG v4.5 software. The results suggest over representation of certain breeding animals and loss of founder genotypes. Mean F of the reference population, consisting of live breeding animals, was 0.03, which has increased in recent generations. The population has had a favourable evolution with regard to number of individuals, although it is very heterogeneous and requires the application of mating criteria tending to the minimization of inbreeding levels per generation.

Keywords : Autochtonous breeds; Genetic resources; Inbreeding.
