Abstract
   "Cal de Bucovina" population is the result of crossbreeding between "Semigreul Românesc" and Hutsul breeds made in the 80's, at Lucina Stud. Although it has some rather interesting characters, unfortunately, they have been little studied and used so that, at present, the population is extremely low, surviving as a nucleus in conservation through the skilled care of the specialists of the Stud. The biological material used in this study was represented precisely by mares that make up the nucleus breeding, breeding activity analysis revealing that the specific indicators as the introduction to breeding age (1817.429 ± 161.861 days), age at first calving (2170 ± 164.567 days), period of gestation (339.7 ± 2.0 days), service period (97.8 ± 25.6 days), calving interval (465.4 ± 36.8 days), etc., have normal values within the species characteristics, which gives us hope in terms of future survival of this population.

Key words: stud, mares, stallions, reproduction
