Corn purchased from commercial sources was split at delivery and was left untreated or treated with a commercial mold inhibitor. Feed was prepared from these two lots of corn from within 1 wk to as much as 20 wk after delivery over the course of two experiments. There was evidence of reduced mold growth due to the mold inhibitor, particularly in the second experiment where initial mold populations were higher. Mycotoxins were evident in feed samples, regardless of the corn treatment. There was no significant effect from the treatment of corn on growth, livability, egg production, feed conversion, egg weight, or the eggshell quality of broiler breeders. Treatment of corn with a mold inhibitor significantly increased hatchability of fertile eggs in both experiments. Fertility was also significantly improved in the second experiment. These data suggest that using corn treated with a mold inhibitor results in significantly better hatchability in broiler breeders than untreated corn, although there were no observed differences in the incidence of mycotoxins in the samples taken.
从商业渠道购买的玉米在交货时进行了分割，一部分未经处理，另一部分用市售防霉剂进行处理。在两项实验过程中，从这两批玉米中制备饲料，时间跨度从交货后1周至20周不等。有证据表明，防霉剂可减少霉菌生长，尤其是在初始霉菌数量较高的第二项实验中。无论玉米如何处理，饲料样本中均存在明显的霉菌毒素。玉米处理对肉种鸡的生长、成活率、产蛋量、饲料转化率、蛋重或蛋壳质量均无显著影响。在两项实验中，用防霉剂处理玉米均显著提高了受精蛋的孵化率。在第二项实验中，受精率也显著提高。这些数据表明，使用经防霉剂处理的玉米，肉种鸡的孵化率显著高于未处理的玉米，尽管在采集的样本中未观察到霉菌毒素发生率的差异。
