Seasonal mobilization of calcium in relation to antler growth has focused on the site of new bone growth, but systemic changes have not been fully studied. Several theories on the role of various steroids in activating the transport of calcium to the site of growth have been postulated, but little attention has been paid to the impact on body stores of this essential element. We have analyzed hair calcium levels as an indicator of mineral status and have noted seasonal changes in both males and females. Hair calcium levels in the May and June samples were markedly elevated over the other 10 months in both males and females. To follow up on these observations, we monitored blood serum calcium and serum hydroxyproline as indicators of calcium flux. Serum calcium was significantly higher in June through October than in winter and spring. The flux of calcium as indicated by hydroxyproline was markedly higher in May through August than in a later winter sample, February. Although both males and females demonstrated this change the magnitude of the male response was greater.
