A 10-week feeding experiment was carried out examining the effects of deoxynivalenol (DON)-contaminated maize treated with different sodium sulphite (SoS) concentrations on performance, health and DON-plasma concentrations in fattening pigs. Two maize batches were used: background-contaminated (CON, 0.73 mg/kg maize) and Fusarium-toxin contaminated (DON, 44.45 mg/kg maize) maize. Both were wet preserved at 20% moisture content, with one of three (0.0, 2.5, 5.0 g/kg maize) sodium sulphite concentrations and propionic acid (15%). Each maize batch was then mixed into a barley-wheat-based diet at a proportion of 10%, resulting in the following 6 feeding groups: CON− (CON + 0.0 g SoS/kg maize), CON2.5 (CON + 2.5 g SoS/kg maize), CON5.0 (CON + 5.0 g SoS/kg maize), DON- (DON + 0.0 g SoS/kg maize), DON2.5 (DON + 2.5 g SoS/kg maize) and DON5.0 (DON + 5.0 g SoS/kg maize). Dietary DON concentration was reduced by ~ 36% in group DON2.5 and ~ 63% in group DON5.0. There was no impact on ZEN concentration in the diets due to SoS treatment. Pigs receiving diet DON- showed markedly lower feed intake (FI) compared to those fed the control diets. With SoS-treatment of maize, FI of pigs fed the DON diet (DON5.0: 3.35 kg/d) were comparable to that control (CON−: 3.30 kg/day), and these effects were also reflected in live weight gain. There were some effects of SoS, DON or their interaction on serum urea, cholesterol and albumin, but always within the physiological range and thus likely negligible. SoS wet preservation of Fusarium-toxin contaminated maize successfully detoxified DON to its innocuous sulfonates, thus restoring impaired performance in fatteners.

使受脱氧雪腐烯酚（DON）污染的饲料排毒：亚硫酸钠（SoS）处理对育肥猪的生产性能和血液参数的影响。

进行了为期10周的饲养实验，以不同的亚硫酸钠（SoS）浓度处理脱氧雪茄烯（DON）污染的玉米对育肥猪的生产性能，健康状况和DON血浆浓度的影响。使用了两批玉米：背景污染（CON，0.73 mg / kg玉米）和镰刀菌玉米（DON，44.45 mg / kg玉米）被毒素污染。两种都以20％的水分含量湿保存，具有三种（0.0、2.5、5.0 g / kg玉米）亚硫酸钠浓度和丙酸（15％）之一。然后将每批玉米以10％的比例混合到基于大麦小麦的日粮中，分为以下6个饲养组：CON-（CON + 0.0 g SoS / kg玉米），CON2.5（CON + 2.5 g SoS / kg玉米），CON5.0（CON + 5.0 g SoS / kg玉米），DON-（DON + 0.0 g SoS / kg玉米），DON2.5（DON + 2.5 g SoS / kg玉米）和DON5.0 （DON + 5.0 g SoS / kg玉米）。DON2.5组的膳食中DON浓度降低了〜36％，DON5.0组中的降低了约63％。SoS处理不会影响日粮中ZEN的浓度。与饲喂对照日粮的猪相比，接受DON-日粮的猪的采食量（FI）明显降低。通过SoS处理玉米，饲喂DON日粮的猪的FI（DON5.0：3.35千克/天）与对照组（CON-：3.30千克/天）相当，这些影响也反映在活体重增加上。SoS，DON或它们的相互作用对血清尿素，胆固醇和白蛋白有一些影响，但始终在生理范围内，因此可能微不足道。SoS湿保存受镰刀菌毒素污染的玉米成功地将DON解毒成其无害的磺酸盐，从而恢复了增脂剂中受损的性能。
