We investigated the whole-body crude nutrient (fat, protein, ash) and mineral (Ca, P, Mg, Na, K) composition of mustached bats of three different groups: animals from the wild (n = 6), and animals from captivity on an unsupplemented feeding regime of mealworms (n = 7), and on a feeding regime in which the mealworms were kept on a mineral substrate prior to feeding (n = 6). It was shown that mealworms from the mineral substrate had higher Ca contents than mealworms from the conventional substrates. In an earlier study, differences in bone mineral density had been found between the groups. These differences, however, were not reflected in differences in whole-body composition. Captive animals showed a larger variation in body weight and fat content, indicating potential shortcomings of the dietary and husbandry regime.
我们研究了三个不同组的髯蝠的全身粗营养素（脂肪、蛋白质、灰分）和矿物质（钙、磷、镁、钠、钾）组成：野生蝙蝠（n = 6），以及圈养蝙蝠，一组以未添加营养的黄粉虫为食（n = 7），另一组以在喂食前饲养在矿物质基质上的黄粉虫为食（n = 6）。结果表明，来自矿物质基质的黄粉虫比来自传统基质的黄粉虫钙含量更高。在早期的一项研究中，发现这些组之间存在骨矿物质密度差异。然而，这些差异并未反映在全身组成的差异上。圈养动物的体重和脂肪含量变化更大，表明饮食和饲养方式可能存在缺陷。
