[Mycoflora of hay and straw]

Studies were carried out on hay and straw to establish the composition of mycoflora in them. They were sampled both at the time of harvesting and after storing for four to five months. It was found that the hay and straw were most often inseminated with spores of the fungus species Alternaria tenuis, Aspergillus fumigatus, Mucor hiemalis, Penicillium sp., and more rarely with spores of Fusarium, Chaetomium, Scopulariopsis, Cladosporium, Trichoderma, and Stachybotrys alternans. It was demonstrated that when moistening of the feeds set in the period of taking in or in storage the mycoflora increased both in species composition and in extent of insemination. The presence of Alternaria tenuis was mostly demonstrated (up to 85 per cent) for hay, and (up to 100 per cent) for straw.
