Body weight, early growth and antler size influence antler bone mineral composition of Iberian Red Deer (Cervus elaphus hispanicus)
چکیده انگلیسی

Researchers have devoted little attention to the possibility that the chemical composition of bone might be variable under normal nutrition conditions. This study assessed antler bone composition of 25 one-year old deer (spikes). Antler content of ash, Ca, P, K, Na, Mg, Fe and Zn was assessed in base and tine, and the mean composition or the difference in composition between tine and base was used to explain variability in antler length, weight and perimeter. In turn, mean composition and difference in concentration of each mineral were related to body measures at 1 year of age, weight at birth, weight at 1 year of age and weight gains during lactation, or between weaning and year of age. Chemical composition differed between base and tine in ash, Ca, P, K, Zn and Fe, but not in Na or Mg. Composition explained a mean variability of 77% in antler length and weight. Body weight and size, in turn, influenced mineral composition. The greatest body effect was that of gains during lactation on principal components analysis factor related to Ca, P and other major minerals such as Na, K or Mg. Antler bone composition is variable in normal conditions and such variability may play a role in biomechanical properties of the antler, but it is also likely to show the nutritional status or physiological effort to grow antlers. Assessing bone composition may emerge as a new useful tool to obtain information regarding bone biology and its bearer in other species including ours.
