Sex-specific hormones were found to influence the bristle's mineral content. The bristles of female (N=151) and male (N=152), 42-day old piglets did not differ in the proportion of the elements under study (P greater than 0.05). The bristles of 36 female and 36 male castrated fattening pigs in the 40-110 kg weight range did not reveal significant differences either (P greater than 0.05). The bristles of sows and boars showed differences in the contents of ash, Mg, K, Na, P, Zn and Mn (P greater than 0.05) as well as in the contents of Fe (P greater than 0.01) and Cu (P greater than 0.05). The difference for the Ca-content could not be statistically secured (P greater than 0.05). The content of the bristle or hair of sexually mature animals in certain elements is influenced by sex hormones and should be regarded as a secondary sexual characteristic.
研究发现，性别特异性激素会影响猪鬃的矿物质含量。42日龄雌性仔猪（N = 151）和雄性仔猪（N = 152）的猪鬃中，所研究元素的比例没有差异（P>0.05）。体重在40 - 110千克范围内的36头雌性和36头雄性去势育肥猪的猪鬃也未显示出显著差异（P>0.05）。母猪和公猪的猪鬃在灰分、镁、钾、钠、磷、锌和锰的含量上存在差异（P>0.05），在铁含量上存在差异（P>0.01），在铜含量上也存在差异（P>0.05）。钙含量的差异在统计学上无法确定（P>0.05）。性成熟动物的猪鬃或毛发中某些元素的含量受性激素影响，应被视为第二性征。
