Research concerning the reproduction indices in Semigreu of Transylvania equine function of years (2008 - 2012), and by total population

The values of the main reproduction indices of the Semigreu of Transylvania horses from Beclean Stud, Romania are presented and analyzed in this paper. They are reported based on the inventory data of the reproduction activity of 87 dams, recorded during 2008-2012. Based on raw data obtained from the stud inventory, the most significant reproduction indices were calculated: number of cycles/gestation, number of freshening/gestation, service-period (SP), gestation length (DG) and calving interval. The analyzed indices were determined function of years. The average values of the reproduction indices emphasize a normal evolution of the reproduction function in Semigreu of Transylvania mares. The differences, by years, between the reproduction indices are mainly resulted from the influence of several factors that differ from a year to another, as social deficiencies, technological deficiencies, etc.
