中文摘要 | 本試驗旨在觀察小型有色肉鷄(土鷄)在不同生長階段,長期餵飼含低量黃麴毒素B₁的反應,作為釐定飼糧中黃麴毒素容許量之參考。 試驗共進行三次。試驗一在0~14週齡;試驗二在4~14週齡;而試驗三在10~14週齡時,飼予試驗飼糧。每一試驗均有六處理,黃麴毒素B₁含量分別為0、25、50、100、200和400ppb。試驗於14週齡結束,測定項目包括鷄隻增重、飼料利用效率、14週齡肝重,以及肝臟和胸肌中黃麴毒素之殘留量。 小型有色肉鷄對黃麴毒素的耐受性頗高,鷄隻不論自日齡、4週齡或10週齡開始餵飼含有黃麴毒素的飼糧,增重均類似對照組,沒有受到抑制或顯現病態與不良反應。飼料利用效率沒有規律變化;肝重/體重的比率也不因餵飼低量黃麴毒素而增大。鷄隻攝食含有50ppb黃麴毒素的飼糧,不論是在那一生長階段給予,肝臟中均可檢測出殘留,但胸肌中則不易測出。 |
英文摘要 | The objective of the research was to investigate the effect of feeding low level of aflatoxin B₁ on the performance of colored meat-type chicken at different growth stages for setting up the aflatoxin B₁ allowance in the diet. Three experiments were conducted. In each experiment, chicks were fed corn-soybean diets containing 0、25、50、100、200 or 400 ppb of aflatoxin B₁ from day-old, 4 weeks or 10 weeks old. The experiment lasted for 14 weeks, and the parameters measured were body weight gain, feed efficiency, liver weight and aflatoxin B₁ residue in livers and breast muscle. The tolerance for aflatoxin B₁ in the chickens is rather high. No significant mortality and growth-suppressing effect could be detected. There were no consistent effects on feed efficiency and liver to body weight ratio due to feeding low level of aflatoxin. Aflatoxin B₁ residue was found in liver from chickens fed diet containing 50 ppb B₁ or more, but was not easy to be detected in the breast muscle. |
