The values of the main reproduction indices for the Transylvanian half-heavy horsematerial from Beclean stud farm are presented and analysed in this paper. Theanalysis is based on the data obtained from the evidence of the reproduction activityof 126 mother mares, data recorded in the period between 2000 and 2006. The mostsignificant indices have been rated, as the number of cycles/gestation, the number ofmatings/gestation, service-period (SP), gestation period (GP) and the periodbetween bringing forth. The studied indices have been determined based on thenumber of bringing forth, on genealogical lines and on the entire population andaccording to the male stud used for mating. The connection between the puerperalperiod and the main reproduction indices has also been estimated. The averagevalues of the analysed reproduction indices show a normal evolution of thereproduction function for the Transylvanian half-heavy mother mares, a value that can behighlighted by creating some absolute accordance between the biological requests of thisbreed and the technological conditions which are provided for them.
