Abstract. The article presents the materials of physiological bases of intensification of reproduction of deer conducted in three periods of research: 1 – in the period of active sexual season (August – November); 2 – in the period of fruiting (October – April – May); 3 – in the period of calving and postpartum period (April – June). During calving the whole breeding stock of the reindeer herd was monitored with the help of experienced shepherds. The number of daily calving were taken into account by the marking of the newborn. In the postpartum stage, attention was paid to the behavior of the important, the mother’s attitude to the newborn, the time of the first sucking, the timing of the separation of the afterbirth. From the given examples it is clear that the deer rut does not end in October – November, some does can be covered in December – January. In reindeer husbandry, as a rule, free mating is used. One of the choir – the manufacturer accounts for 12–18 does. The chorus is easy to find a actually female in the hunt and stalking her prior to coating. Terms calving and rut in different ulus of the Republic of Sakha (Yakutia), located in different climatic zones, vary. So the earliest terms of manifestation of sexual excitement begins at deer of breed Hargin of the Nizhnekolymskiy ulus which are in softer conditions of existence, in the period from August 22 to September 20, and mass (91,4 %) – from August 22 to September 10. Then begins the rut of deer in the Momskiy ulus (Alpine zone) and Haryyalakh herds of Olenek ulus (taiga zone), which lasts from 6 September to 10–15 October, and the mass (94 %) – from 11–15 September to 30 September – 5 October. However, the individual does births occur in June – August and even in September. In the study of the pregnant state of important women, we found inappropriate pregnancy at certain times.
