中文摘要：本研究旨在调查有机农场和传统农场的裹包青贮（主要是禾本科草）中生物胺和霉菌毒素的浓度，并将这些参数与发酵参数相关联。研究表明有机农场和传统农场青贮中生物胺形成或霉菌毒素含量有差异，但测量值很低，不会影响动物健康。此外，这些差异也可能由有机青贮和传统青贮样品中干物质含量和植物成熟度的差异造成。
外文摘要：The aim of the current study was to investigate biogenic amines and mycotoxins concentrations in baled silage (mainly Poaceae family grasses) prepared in organic and conventional farms and to relate these parameters to fermentative parameters. The mean dry matter (DM) content was 364.10 +/- 93.31 and 424.70 +/- 95.93g/kg in the silage from organic and conventional farms respectively. The silage samples from organic farms had 17.00% higher (P <= 0.05) tyramine (TY) than the silage from conventional farms. Conventional farm samples were characterized by 46.00% higher histamine (HIS) (P <= 0.05), 9.80% higher putrescine (PUT) (P <= 0.05), 17.30% higher cadaverine (CAD) (P <= 0.05). Aflatoxins (AFL) (total) and zearalenone (ZEN), T-2/HT-2 concentrations were higher respectively 16.00% (P <= 0.05) and 13.40% (P <= 0.05), 1.80% (P <= 0.05) in the silage prepared in organic farms. Deoxynivalenol (DON) concentration was higher 42.40% (P <= 0.05) in silage from conventional farms. Volatile fatty acids (VFA), lactic acid, ethanol, pH and ammonia nitrogen showed that the silage samples from organic and conventional farms were of good quality. Our study suggests differences in biogenic amine formation or mycotoxins content in silage from organic and conventional farming, but, overall, the measured values are too low to be relevant for animal health. Furthermore, these differences might as well be due to the difference in dry matter content and plant maturity between the organic and conventional silage samples.
