Abstract
The northeast of Argentina is a livestock production area. Generally cattle in this area feed on grasslands and improved pastures, but their food is often supplemented with grains, protein sources and reserves in the form of hay and/or silage. However, these food sources may be colonised by fungi including Fusarium, which produce mycotoxins, one of which is zearalenone (ZEA). The aim of this study was to relate the natural occurrence of ZEA in Colonia [ver mas...]

dc.description.abstractThe northeast of Argentina is a livestock production area. Generally cattle in this area feed on grasslands and improved pastures, but their food is often supplemented with grains, protein sources and reserves in the form of hay and/or silage. However, these food sources may be colonised by fungi including Fusarium, which produce mycotoxins, one of which is zearalenone (ZEA). The aim of this study was to relate the natural occurrence of ZEA in Colonia Benítez (Chaco Province) to the temperature and moisture of the autumn preceding the winter collection of fodder samples in 2012 and 2013. The forage resources of 2012 had high ZEA contents (310 to 6279 μg/kg) in 47 % of the samples, whereas those from 2013 exhibited intermediate values of ZEA contents (131 to 296 μg/kg) in 41.6 % of the samples and low contents (< 2 to 91 μg/kg) in 50 % of the samples. The incidence of F. semitectum was higher in 2012 compared to 2013. The high concentration of ZEA found in many of the forage samples collected in July 2012 was preceded by autumn weather conditions that were exceptionally conducive to plant stress. In contrast, when meteorological factors were within normal values (as in the autumn of 2013), the pasture and feed collected in winter showed intermediate to low concentrations of ZEA. The temperature and moisture conditions prevailing during the autumn of 2012 accelerated canopy senescence of the forage plants available for livestock at the beginning of the winter. Consequently, the weather conditions during the autumn 2012 likely favoured the sharp increase in ZEA content in these pastures when compared to the other two seasons.eng
