Comparative analysis of the mycobiota and mycotoxins contaminating corn trench silos and silo bags
Silage is one of the most important feed sources for bovines. Mycotoxin contamination of feedstuffs is a worldwide concern. The aim of this study was to compare mycobiota and levels of aflatoxin B 1 (AFB 1), fumonisin B 1 (FB 1), deoxynivalenol (DON), zearalenone (ZEA) and patulin (PAT) in corn tren...

Mycotoxin contamination of feedstuffs is a worldwide concern. The aim of this study was to compare mycobiota and levels of aflatoxin B 1 (AFB 1), fumonisin B 1 (FB 1), deoxynivalenol (DON), zearalenone (ZEA) and patulin (PAT) in corn trench silos and silo bags. RESULTS: Dry matter was higher in trench silos. Counts varied from not detected to 10 8 CFU g -1 in both trench silos and silo bags. Isolation frequencies of Aspergillus spp. and Fusarium spp. were higher in trench silos, whereas Penicillium spp. was higher in silo bags. Silo bags showed less diversity than trench silos. Strains isolated produced AFB 1, FB 1 and PAT. In trench silos, AFB 1 was the only mycotoxin detected (1-160 μg kg -1). In silo bags AFB 1 levels varied from 5.8 to 47.4 μg kg -1. DON was detected in two silo bag samples. CONCLUSION: When handling is adequate the reduction of mould and mycotoxin contamination in silo bags is considerable. This study will enable estimation of the mycotoxicological risk of different ensiling practices and determination of the most adequate method to minimize economic losses and reduce hazard to animal and human health. © 2011 Society of Chemical Industry. 2011 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00225142_v91_n8_p1474_GonzalezPereyra http://hdl.handle.net/20.500.12110/paper_00225142_v91_n8_p1474_GonzalezPereyra |
