嘔吐毒素,家禽的中毒數值是ppm計(1/1,000,000)
黃麴毒素的中毒量是以ppb計(1/1,000,000,000)
相差1,000倍
家禽嘔吐毒素的中毒劑量是10ppm (10,000ppb)
而這一次驗出來的結果是2,483ppb
檢驗單位的檢驗報告是否應將中毒劑量列在檢驗結果旁邊(有如體檢報告),這樣就不會讓畜主誤會,或被銷售人員錯誤引用
獸醫師俱有不錯的偵查能力,所以一出現超出正常死亡率時就應該找獸醫師
畜主保護自己的權力應依正規方式採樣並送俱有公信力的單位

Effects of feeding deoxynivalenol (DON, vomitoxin)-contaminated wheat to female White Leghorn chickens from day old through egg production.
US Department of Agriculture, Veterinary Toxicology and Entomology Research Laboratory, College Station, Texas 77841.
Abstract: White Leghorn chickens one day of age were fed starter and grower diets containing either a control (noncontaminated) wheat diet or a naturally contaminated deoxynivalenol (DON) wheat diet (18 mg DON/kg) from 1 day of age to the onset of egg production. The hens were then placed on their respective layer diets of control wheat or DON-contaminated wheat (18 mg DON/kg) for six 28-day egg production periods. Feeding the DON-contaminated diet did not significantly influence body weights during the growing or the laying phases. Overall, hen-day egg production and egg weights were significantly higher for hens receiving the DON diet. Feeding DON contaminated wheat caused no significant changes in percent shell, albumen height, percent fertility, percent hatch of fertile eggs, percent hatch of eggs set, or weight of chicks at hatch. There were slight, although significant, changes in shell weight and shell thickness and in some serum chemistry values. There were no significant differences in the hematology parameters measured or in prothrombin times. None of the eggs collected from hens fed the control and the DON-contaminated wheat diet contained detectable quantities of DON. Microscopic examination of sections of the liver, kidney, and proventriculus of control and treated hens revealed no unusual histopathology. The results indicate that feeding DON at relatively high levels beginning at 1 day of age and continuing through six egg production periods had only slight effects on the parameters measured.
