Retrieval of "Ergothioneine" as strongly antioxidant matter from feed of livestock animal and verification of antioxidant ability in the lean

将含有抗氧化能力的麦角硫蛋白(ERT)的金黄色平菇菌床发酵全混合日粮(TMR：试验区)或含有稻草的发酵TMR(对照区)饲喂绵羊育肥，由于稻草的消化率较高，试验区7.1和试验区10.2的干物质基础饲料转化率分别为7.1和10.2。展示后，实验区背最长肌高铁血红蛋白有降低的趋势。在展后第2天和第3天，试验区的红色程度高于对照区。用高效液相色谱和UPLC-PDA-ESI-MS检测器不能清楚地检测到废弃蘑菇床和稻草中的ERT。除ERT外，在废弃蘑菇床或不明物质中添加ERT的效果被认为是绵羊倾向于通过饲喂含有金黄色平菇的废弃蘑菇床来达到抗氧化的目的。

When fermented total mixed ration (TMR: experimental plot) containing the waste mushroom bed of golden oyster mushroom which contains ergothioneine (ERT) with anti-oxidization ability or the fermented TMR (control plot) containing rice straw was fed to sheep and fattened, the feed conversion ratios as dried matter basis were 7.1 in control plot 7.1 and 10.2 in experimental plot 10.2, since the digestibility was superior in rice straw. The metmyoglobin of longissimus dorsi muscle after exhibition tended to change low for experimental plot. The degree of red color was higher in experimental plot than control plot on 2nd and 3rd days after exhibition. ERT in waste mushroom bed and rice straw could not be clearly detected by HPLC and UPLC-PDA-ESI-MS detector. The effect of ERT containing in waste mushroom bed or an unidentified material except for ERT was considered that the lean of sheep tended to do the antioxidant by feeding the waste mushroom bed containing golden oyster mushroom.
