A performance trial was conducted to evaluate the effect of microbially detoxified moldy corn in a corn-soybean meal-based starter diet for young pigs. Moldy corn containing 450 ppm of vomitoxin replaced clean corn in a control diet to give a diet containing 5 ppm of vomitoxin. The same amount of moldy corn was microbially detoxified by incubation with the contents of the large intestine of chickens (CLIC) and then incorporated into the control diet to give a "detoxified" vomitoxin diet, which contained 2.1 ppm of vomitoxin. A paired diet was formulated by incorporating the untreated moldy corn into the control diet to give a diet containing the same level of vomitoxin as the "detoxified" vomitoxin diet. Clean corn was also treated with CLIC and replaced corn in the control diet to give a biologically treated control diet. Each diet was fed to six pigs (three gilts and three boars) for 5 d and then all pigs were changed to the control diet for a further 5-d feeding period. During the first 5-d feeding period, no differences were observed in pigs fed either the control diet or the biologically treated control diet. A diet containing 5 ppm of vomitoxin decreased the pigs' daily feed consumption, weight gain, and feed efficiency by 25, 57, and 45%, respectively, compared with the control diet (P < or = .05). Daily feed intake, weight gain, and feed efficiency in pigs fed the "detoxified" vomitoxin diet were 19, 54, and 37% greater, respectively, than for pigs fed the vomitoxin diet (P < or = .05).(ABSTRACT TRUNCATED AT 250 WORDS)
进行了一项性能试验，以评估微生物解毒的发霉玉米在以玉米-豆粕为基础的仔猪开食料中的效果。含有450 ppm呕吐毒素的发霉玉米替代对照日粮中的干净玉米，使日粮中呕吐毒素含量达到5 ppm。将等量的发霉玉米与鸡的大肠内容物（CLIC）一起孵育进行微生物解毒，然后加入对照日粮中，制成“解毒”呕吐毒素日粮，其呕吐毒素含量为2.1 ppm。通过将未处理的发霉玉米加入对照日粮中，配制出一种配对日粮，使其呕吐毒素水平与“解毒”呕吐毒素日粮相同。干净玉米也用CLIC处理，并替代对照日粮中的玉米，制成生物处理对照日粮。每种日粮饲喂6头猪（3头小母猪和3头公猪）5天，然后所有猪再更换为对照日粮，继续饲喂5天。在第一个5天的饲喂期内，饲喂对照日粮或生物处理对照日粮的猪未观察到差异。与对照日粮相比，含有5 ppm呕吐毒素的日粮使猪的日采食量、体重增加和饲料效率分别降低了25%、57%和45%（P≤0.05）。饲喂“解毒”呕吐毒素日粮的猪的日采食量、体重增加和饲料效率分别比饲喂呕吐毒素日粮的猪高19%、54%和37%（P≤0.05）。（摘要截短至250字）
