MARTINEZ, M.; ARMSTRONG, E.; GAGLIARDI, R.  y  LLAMBI, S.. Pedigree analysis of the canine breed Cimarron Uruguayo. Arch. zootec. [online]. 2011, vol.60, n.232, pp.1327-1330. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000400049.

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.

Palabras clave : Autochtonous breeds; Genetic resources; Inbreeding.
