Abstract

Silage maize is a key component of the diet of dairy cattle in Galicia (NW Spain). In the field, maize forage can becontaminated with mycotoxins, produced mainly by fungal species of the genus Fusarium, which persist in silage and canadversely affect animal production and health. Natural incidence and diversity of Fusarium species in stalks, leaves andkernels of six forage maize hybrids, grown in two Galician sites, were studied to estimate the risk of mycotoxins in forage. Attime of cutting for silage, there was a high overall incidence of Fusarium in the three types of plant material of all hybrids inboth sites. The incidence was higher in kernels than in stalks and leaves. In Mazaricos, five toxigenic species of Fusariumwere identified, F. cerealis and F. graminearum being found in stalks, leaves and kernels of the six hybrids. In Silleda, sixFusarium species were detected, and three of them, namely F. avenaceum, F. cerealis and F. culmorum, in the three types ofplant material of all hybrids
