Abstract
Whereas the animal breeding aimed the population reproduction organization, reproduction structure analysis is a significant share in the breeding work, especially since this structure components, the man holding the main levers of change in the genetic structure of populations, by inducing genetic progress. Biological material used is represented by the entire livestock of the stud farm Beclean pe Someş (transferred in October of 2011 from the Slatina stud farm), belonging to the Furioso-North Star (and not just evidence of it), existing at the time of analysis (30.11.2011). To determine the structure of the population, have used clasical statistical methods. The results reflect the existence of a population with a normal sex ratio, with a high variability in the size of the family, with an unbalanced age structure, with a high generation interval, with less than 10% of immigrants. For the future of the population becomes useful as decisions on the organisation of reproduction activity to take after consulting specialists, whereas a wrong decision can have negative consequences for the future of a population subject to permanent danger of inbreeding.
