In one experiment, the effect of inorganic sorbents on the metabolic fate of aflatoxin B1 (AFB1) was studied in turkey poults. At 5 weeks of age, female poults were surgically colostomized and 9 days later orally dosed with 0.75 mg AFB1/kg BW. Hydrated sodium calcium aluminosilicate (HSCAS), acidic HSCAS, and activated charcoal (AC) were tested, by concomitant administration with AFB1. Urine was collected up to 48 h post-dosing and analyzed for aflatoxin M1 (AFM1) which was the major metabolite found in all treatment groups. Hydrated sodium calcium aluminosilicate, previously proven beneficial in alleviating aflatoxicosis in farm animals, reduced urinary AFM1 output when orally dosed simultaneous with AFB1. Also, acidic HSCAS and AC significantly decreased AFM1 excretion when administered concomitantly with AFB1. A second experiment was conducted to evaluate the ability of two types of AC to modify aflatoxicosis when added to aflatoxin (AF)-contaminated (from culture material) diets of turkey poults. Although AC was able to decrease AFM1 excretion in the first experiment, no protective effects from AF toxicity were observed in the feeding study.
在一项实验中,研究了无机吸附剂对火鸡雏禽黄曲霉毒素B1(AFB1)代谢归宿的影响。5周龄时,对雌性雏禽进行外科结肠造口术,9天后口服0.75毫克AFB1/千克体重。通过与AFB1同时给药,测试了水合硅铝酸钙钠(HSCAS)、酸性HSCAS和活性炭(AC)。给药后48小时内收集尿液,并分析黄曲霉毒素M1(AFM1),其是所有治疗组中发现的主要代谢产物。水合硅铝酸钙钠先前已被证明对减轻农场动物的黄曲霉毒素中毒有益,当与AFB1同时口服给药时,可降低尿液中AFM1的排出量。此外,酸性HSCAS和AC与AFB1同时给药时,可显著降低AFM1的排泄。进行了第二项实验,以评估两种活性炭添加到受黄曲霉毒素(AF)污染(来自培养材料)的火鸡雏禽日粮中时改变黄曲霉毒素中毒的能力。尽管在第一项实验中活性炭能够降低AFM1的排泄,但在喂养研究中未观察到对AF毒性的保护作用。
