ASPECTS REGARDING FUNGI INCIDENCE IN FIBROUS AND SILAGE FODDER

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.
