研究了黄曲霉毒素（AF）和玉米赤霉烯酮（ZEA）及其复配对蛋鸡产蛋性能、蛋品质和蛋中毒素残留的影响，以及枯草芽孢杆菌生物降解产物（BDP）对这些影响的改善效果。使层经受两阶段实验。第一阶段是中毒期（18-23周），饲喂7只（3 x 2 + 1）日粮（3个真菌毒素处理：AF（123.0 μ g/kg）、ZEA（260.2 μ g/kg）或AF + ZEA（123.0 + 260.2 μ g/kg）; 2个处理有或没有BDP（1000 g/t）;对照组不含毒素也不含BDP）。下一个阶段是恢复期（24-29周），在此期间，鸟类被喂食无毒饮食。与对照组相比，AF组和AF + ZEA组在中毒期的产蛋量、采食量和蛋壳厚度较低，AFB（1）、AFB（2）和AFM（1）残留量较高。此外，AF和ZEA对产蛋量和采食量具有协同效应。此外，AF单独或与ZEA组合对恢复期的产蛋性能具有持续毒性作用。添加BDP抵消了这些负面影响，表明BDP对饲喂污染饲料的蛋鸡具有保护作用。(C)2016爱思唯尔有限公司版权所有
The toxic effect of aflatoxins (AF) and zearalenone (ZEA) and their combination on laying performance, egg quality and toxins residues in eggs, as well as the efficacy of Bacillus subtilis biodegradation product (BDP) for ameliorating these effects in layers were evaluated. Layers were submitted to a two phase experiment. The first phase was an intoxication period (18-23 wk) with birds fed 7 (3 x 2 + 1) diets (3 treatments with mycotoxins: AF (123.0 mu g/kg), ZEA (260.2 mu g/kg), or AF + ZEA (123.0 + 260.2 mu g/kg); 2 treatments with or without BDP (1000 g/t); and a control group contained no toxins nor BDP). The next phase was a recovery period (24-29 wk) in which birds were fed a toxin-free diet. In the intoxication period, AF and AF + ZEA groups exhibited lower egg production, feed intake and shell thickness, and higher AFB(1), AFB(2) and AFM(1) residues as compared with the control group. In addition, AF and ZEA exerted synergistic effects on egg production and feed intake. Moreover, AF alone or combined with ZEA had a continuous toxic effect on laying performance in the recovery phase. Addition of BDP offset these negative effects, showing that BDP has a protective effect on layers fed contaminated diets. (C) 2016 Elsevier Ltd. All rights reserved.
