Macro and micro mineral content of velvet antler harvested on day 36 from timor deer in different age class. Macro and micro minerals content, of velvet antler, were higher in the older deer than those in younger deer.
Quality of velvet antler is based upon its protein content indicating by amino acids composition. Protein content of velvet antler was negatively correlated with the Ca content. The increase in Ca content, which is inline with the growth of velvet antler, results in a decrease in protein content and therefore its total amino acids, uronic acid, and sialic acid content decrease. On the other hand, the increase in Ca is accociated with the increase in ash and collagen content of the velvet, and therefor reduces the quality of velvet (Jeon et al., 2009).
Amino acids content of velvet antler harvested on day 36 from Timor deer in different age classes is presented in Table 9. There was no different in essential amino acid content of velvet antler among age classes of the deer. Most essential amino acids in the velvet antler were likely not affected by the intake of protein or other nutrients. However the nutrient intake might increase the total weight of velvet antler, therefore they increaed the total of nutrients including amino acids as components of the velvet antler. Aspartic acid, glutamic acid, and prolin content in velvet antler were high in the older deer. The older deer indicated higher metabolism activity in synthesizing non-essential amino acids and deposited the amino acids in the velvet antler.
