STUDY OF FUNCTIONAL ACTIVITY OF THE ENDOCRINE GLANDS IN MARALS DURING ONTOGENESIS DEPENDING ON VELVET ANTLER PRODUCTION PERFORMANCE
Abstract
The hormone content in blood serum of male deer was studied. It has been established that some changes in the functional activity of the endocrine glands take place in animals during ontogenesis. The level of progesterone is observed to increase in marals at 1.5 years of age as compared with calves, and to reduce with the first antler growth. Concentrations of testosterone, cortisol and estradiol increase with reaching the animals’ age of 1.5 years and do not change in animals getting their first antlers. In the course of determining the hormone content depending on the age, a possibility has been found to predict velvet antler production performance at the early age of young bucks by testosterone concentration in their blood serum.
