中文摘要:本文旨在研究黄曲霉毒素B1 (AFB₁)的毒性效应,并评估破壁灵芝孢子(SSGL)对减轻肉鸡黄曲霉毒素中毒的作用。结果显示,整个实验过程中,日粮受低水平AFB1污染显著降低了肉鸡的平均日采食量(p < 0.05)和平均日增重(p < 0.05);血清总蛋白、IgA和IgG的含量均显著下降。此外,日粮受低水平AFB1污染不仅能显著升高肉鸡肝脏及脾脏中过氧化氢和脂质过氧化水平(p < 0.05),而且能显著降低总抗氧化能力及过氧化氢酶、谷胱甘肽过氧化物酶、羟自由基清除剂的活性(p < 0.05);另外,受AFB₁污染的日粮中掺入了SSGL后能抵消这种负作用,表明SSGL对黄曲霉毒素中毒有保护作用。
外文摘要:This study was conducted to investigate the toxic effects of aflatoxin B₁ (AFB₁) and evaluate the effects of sporoderm-broken spores of Ganoderma lucidum (SSGL) in relieving aflatoxicosis in broilers. A total of 300 one-day-old male Arbor Acre broiler chickens were randomly divided into four dietary treatments; the treatment diets were: Control (a basal diet containing normal peanut meal); AFB₁ (the basal diet containing AFB₁-contaminated peanut meal); SSGL (basal diet with 200 mg/kg of SSGL); AFB₁+SSGL (supplementation of 200 mg/kg of SSGL in AFB₁ diet). The contents of AFB₁ in AFB₁ and AFB₁+SSGL diets were 25.0 μg/kg in the starter period and 22.5 μg/kg in the finisher period. The results showed that diet contaminated with a low level of AFB₁ significantly decreased (p < 0.05) the average daily feed intake and average daily gain during the entire experiment and reduced (p < 0.05) serum contents of total protein IgA and IgG. Furthermore, a dietary low level of AFB₁ not only increased (p < 0.05) levels of hydrogen peroxide and lipid peroxidation, but also decreased (p < 0.05) total antioxidant capability, catalase, glutathione peroxidase, and hydroxyl radical scavenger activity in the liver and spleen of broilers. Moreover, the addition of SSGL to AFB₁-contaminated diet counteracted these negative effects, indicating that SSGL has a protective effect against aflatoxicosis.
