Role of certain herbal substances and some feed additive mixtures as mold growth and mycotoxins inhibitors on infected corn grains [electronic resource].

Includes references.

Preliminary tests showed that the tested isolates of Aspergillus flavus and Fusarium verticilloides were capable to produce aflatoxins and fumonisins. Moreover, active ingredients of the tested herbal plant extracts were found to include monocyclic terpenes (limonene) and dicyclic terpenes (a-pinene). Besides, other active components were also detected, e.g. anethole in anise oil. thymol and carvacrol in thyme oil, eugenol and thymol in clove oil and dicyclic alcohol in peppermint Feed additive mixtures (FAM), used for poultry (PAM) and cattle (CAM) were tested for their antagonistic and detoxification effect against the tested isolates. Individ ual herbal oils were more effective in reducing fungal growth than their mixtures. More inhibitory effect against F.verticilloides was obtained by clove oil, fOllowed by thyme oil, caraway oil and peppermint Oil mixtures without Sodium chloride were more effective in reducing lungal growth, followed by poultry additive mixtures. Feed additives and oil mixtures were more effective in reducing growth than suppressing mycotoxin production by F.verticilloides, whereas the contrary was observed in A.flavus.
