The ban on piglet castration without anaesthesia poses a challenge for the meat industry since alternatives ensuring the production of flawless pork have to be established. The aim of this study was to evaluate the effects of biochar on skatole and indole concentration in faeces and plasma on a small scale in finishing boars to prove whether biochar was suitable for use in commercial pork production. Moreover, it was investigated whether biochar affects faecal properties or the performance. For a four-week trial period, 54 boars (bodyweight 97.2 ± 6.88 kg) were divided into three groups. The control (BC0) received no dietary biochar, one group received a diet containing 4% coated biochar (corresponding to 2% pure biochar) for the final two experimental weeks (BC2), and another group for the entire four weeks (BC4), respectively, prior to slaughter. Skatole and indole concentrations were measured in faeces and plasma at the beginning, in the middle and at the end of the trial. Mean skatole concentrations did not differ between groups, but in BC2 faecal skatole was significantly decreased at day 26, whereas in BC4 initial and final faecal skatole levels did not differ. At day 15 and 26, the faecal dry matter content was significantly higher in pigs fed the biochar diet ( < 0.05).
禁止在无麻醉情况下对仔猪进行阉割给肉类行业带来了挑战，因为必须找到能确保生产出无瑕疵猪肉的替代方法。本研究的目的是在育肥公猪中小规模评估生物炭对粪便和血浆中粪臭素和吲哚浓度的影响，以证明生物炭是否适用于商业猪肉生产。此外，还研究了生物炭是否会影响粪便特性或生产性能。在为期四周的试验期内，将54头公猪（体重97.2±6.88千克）分为三组。对照组（BC0）不饲喂日粮生物炭，一组在最后两个试验周饲喂含4%包膜生物炭（相当于2%纯生物炭）的日粮（BC2），另一组在整个四周试验期内饲喂（BC4），然后进行屠宰。在试验开始、中期和结束时测量粪便和血浆中的粪臭素和吲哚浓度。各组之间的平均粪臭素浓度没有差异，但在BC2组中，第26天时粪便中的粪臭素显著降低，而在BC4组中，粪便中粪臭素的初始和最终水平没有差异。在第15天和第26天，饲喂生物炭日粮的猪粪便干物质含量显著更高（<0.05）。
