The objective of this study was to investigate the effects of supplemental mycotoxin-sequestering agents on growth performance and nutrient utilization in growing pigs fed deoxynivalenol (DON)-contaminated diets. Twelve barrows with an initial body weight of 35.5 kg (standard deviation = 1.3) were assigned to six dietary treatments in a replicated 6 × 5 incomplete Latin square design. Five experimental diets consisted of an uncontaminated diet (PC), a DON-contaminated diet at 6.89 mg/kg (NC), NC + bentonite 0.5%, NC + yeast cell wall 0.5%, and NC + a mixture product 0.5% which consisted of enzymes, microorganisms, minerals, and plant extracts. Pigs had ad libitum access to the five diets. In the last group, the PC diet was restrictedly provided to pigs at the quantity of feed consumption of the NC group. Average daily gain, average daily feed intake, and gain:feed were not affected by supplemental mycotoxin-sequestering agents except for the mixed product that tended to improve ( = 0.064) gain:feed in pigs fed DON-contaminated diets. The apparent total tract digestibility (ATTD) of dry matter was not affected by DON contamination or by supplemental mycotoxin-sequestering agents, whereas the ATTD of Ca was decreased ( = 0.032) by supplemental yeast cell wall in pigs fed DON-contaminated diets. The ATTD of P was greater ( = 0.042) in pigs fed the NC diet compared with the pigs fed the restricted amount of the PC diet. In conclusion, bentonite and yeast cell wall did not affect growth performance of pigs fed DON-contaminated diets, but a supplemental mixed product consisting of enzymes, microorganisms, minerals, and plant extracts partially alleviated the negative effects of dietary DON on the gain:feed of pigs. Calcium digestibility was decreased by supplemental yeast cell wall in pigs fed DON-contaminated diets. Based on the present work, the use of a mixed product consisting of enzymes, microorganisms, minerals, and plant extracts is suggested, and the reduction of Ca digestibility by yeast cell wall needs to be considered in diet formulations.
本研究的目的是调查添加霉菌毒素吸附剂对饲喂受脱氧雪腐镰刀菌烯醇（DON）污染日粮的生长育肥猪生长性能和养分利用率的影响。选用12头初始体重为35.5 kg（标准差 = 1.3）的公猪，采用重复的6×5不完全拉丁方设计，分为6种日粮处理。5种试验日粮包括一种未受污染的日粮（PC）、一种DON含量为6.89 mg/kg的受污染日粮（NC）、NC + 0.5%膨润土、NC + 0.5%酵母细胞壁，以及NC + 0.5%由酶、微生物、矿物质和植物提取物组成的混合产品。猪可自由采食这5种日粮。在最后一组中，以NC组的采食量向猪限量提供PC日粮。除混合产品外，添加霉菌毒素吸附剂对平均日增重、平均日采食量和料重比均无影响，混合产品倾向于改善（P = 0.064）饲喂受DON污染日粮的猪的料重比。干物质的表观全肠道消化率（ATTD）不受DON污染或添加霉菌毒素吸附剂的影响，而在饲喂受DON污染日粮的猪中，添加酵母细胞壁会使钙的ATTD降低（P = 0.032）。与饲喂限量PC日粮的猪相比，饲喂NC日粮的猪磷的ATTD更高（P = 0.042）。总之，膨润土和酵母细胞壁不影响饲喂受DON污染日粮的猪的生长性能，但由酶、微生物、矿物质和植物提取物组成的添加型混合产品可部分缓解日粮DON对猪料重比的负面影响。在饲喂受DON污染日粮的猪中，添加酵母细胞壁会降低钙的消化率。基于目前的研究结果，建议使用由酶、微生物、矿物质和植物提取物组成的混合产品，并且在日粮配方中需要考虑酵母细胞壁对钙消化率的降低作用。
