Sažetak
Deer antlers (Cervidae family) are fastgrowing bones and the only bone formation in mammals capable of complete regeneration. Males of all species within the deer family (Cervidae) grow antlers, except for the genus Rangifer, where both males and females grow them. Antlers that are changed each year, grow from the frontal extensions – pedicles, that last a lifetime. Each year the last year's antlers are discarded so that the new ones can grow. The study was conducted in the east of the Croatian Danube region (Baranja) during three hunting seasons (2007/2008, 2008/2009 and 2009/2010). A total of 348 pedicles were observed for this study. The height and diameter of pedicles were measured. This paper identified significant changes in height and diameter of pedicles in relation to age and the correlation between height and diameter was also significant. Thus the regression coefficient of pedicles height and age is significant and R = 0.65 (AGE = 15.25 - 0.18 x height) height of pedicles decreases with age) ; also a regression coefficient of pedicle diameter and age is significant and R = 0.85 (AGE = 0.25 x diameter - 4.72) (diameter of pedicle increases with age). Changes of pedicle height and diameter are significant and they have a regular relation to each other and to the age, which is why wildlife managers should seriously take them into account. These average values and mathematical expressions for determining age, given the level of significance, can be used to determine the age and classified into age classes (young males in 3, 4 and 5 years old, middle age males at 6, 7 and 8 years old and mature males 9 and more years old) in the region were the research were conducted.
