ASPECTS REGARDING FUNGI INCIDENCE IN FIBROUS AND SILAGE FODDER

Abstract

The quantitative and qualitative mycological assements in roughages and silo feeds
display a tight corelation betwen the organoleptic characteres and the number of
fungi per gram of feed, thus, Lays and high quality silage, or medium quality silage,
contain below 8x10 5 fungi/g feed in contrast with the inferior ones in wich the
mycotic load7g, feed excudes several times, the above mentioned value.
The ubiguitous presence of Aspergillus, penicillium, mucor, Stachybotzra and
fusarium in hays and silage stands Witress for their pathogenic potentiality.In order
to prevent the spead of mycoses and mycotoxicoses, several precaution measures are
to be taken; thus it is recommmendable that low quality folder with strong
organoleptic alteration, with over 8x10 5 fungi/g feed be ousted from the nutrition
of pregnant females, in lactation or young nuffering from chromic diseases. These
feeds are to be administread restrictively and in mixture with good quality feed, for
the other categories of animals.
