The major boar taint compounds androstenone and skatole as well as the minor compounds indole, 3α-androstenol and 3β-androstenol were determined in back fat samples of 23 male wild boars by applying a recently published SIDA-HS-SPME-GC/MS method. The boar pheromones androstenone, 3α-androstenol and 3β-androstenol were found in extraordinary high concentrations, resulting in mean values of 3329ng/g androstenone, 1273 ng/g 3α-androstenol and 545 ng/g 3β-androstenol. Interestingly, skatole was not detectable in about 50% of the boars and negligibly low in all other samples as expressed by a mean skatole value of only 14 ng/g. Indole was also found in every sample, but again in low concentrations with a mean value of 40 ng/g. Possible factors explaining this remarkably low skatole deposition in wild boars such as intestinal flora and anatomy, dietary composition, housing or genetic predisposition are discussed in this paper.
在 23 头雄性野猪的背脂样本中，通过应用最近发表的 SIDA-HS-SPME-GC/MS 方法，测定了主要公猪异味化合物雄烯酮和粪臭素以及次要化合物吲哚、3α-雄烯醇和 3β-雄烯醇。猪外激素雄烯酮、3α-雄烯醇和 3β-雄烯醇的含量非常高，平均值分别为 3329ng/g、1273ng/g 和 545ng/g。有趣的是，大约 50%的野猪中检测不到粪臭素，而其他所有样本中的粪臭素含量都可以忽略不计，平均值仅为 14ng/g。吲哚也存在于每个样本中，但浓度较低，平均值为 40ng/g。本文讨论了可能导致野猪中粪臭素沉积如此之低的因素，如肠道菌群和解剖结构、饮食组成、饲养或遗传易感性。
