中文摘要:收割前后许多田间性状能影响牧草青贮中霉菌毒素的产生和常规化学成分。本研究旨在检测收割前后田间因素是否能指示牧草青贮中的霉菌毒素的发生和常规化学成分的特性。结果发现收割前后的田间因素一般不能作为青贮中常规化学成分的安全指标。相反,牧草青贮中的恩链孢霉素和白僵菌素通常随收割月(5-10月)而增长。肉眼可见草捆青贮表面的霉菌及牧草青贮窖中顶层腐烂,这是因为发生了andrastin A、霉酚酸及异烟棒曲霉素C污染。
外文摘要:Many pre- and post-mowing on-farm traits influence mycotoxin occurrence and conventional chemical composition in grass silages. The objective of this study was to determine if observed on-farm pre-or post-mowing factors can be used to indicate mycotoxin occurrence or conventional chemical composition traits in grass silages. Over a two year period (2012-2013 and 2013-2014) 290 grass silages were sampled on 145 farms and these consisted of baled (n= 115) and pit (n= 175) silages. On each farm in each year, a questionnaire was completed and pre-and post-mowing factors recorded. The preservation quality was better in pit compared to baled silages in both years and in silages made in Year 2 compared with Year 1. On-farm pre-and post-mowing factors were generally not secure indicators of silage conventional chemical characteristics. In contrast, the occurrence of enniatins and beauvericin generally increased with harvesting month (May-October) for grass silages. Visible mould on baled grass silages and a rotted top layer with pit grass silages were associated with andrastin A, mycophenolic acid and roquefortine C occurrence.
