Abstract
This study is a part of an ample research concerning the genetic analysis (history) of Lipizzan horses from Beclean studfarm. The genetic analysis studies are a part of Animal Genetic Resources Management because just start of them we elaborate the strategies for inbreeding management. This study has as purpose to present two important aspects of genetic analysis: reproductive isolation level and age structure. This parameters has a capital importance in animal breeding because there has a directly influence in animal population evolution.
The reproductive isolation situation was quantified using the relation elaborated by S. Wright in 1921.
The age structure situation is based on the age distribution histogram.
The analysis showed that the Hucul horse from Lucina stud is a reproductively isolated population and have its own evolutionary path. Age structure is not balanced with negative repercurssions on generation interval.

Key words: Hucul, Lucina, reproductive isolation, structure
