Abstract

Aflatoksini su jedna od najvećih prijetnji u proizvodnji hrane za životinje zbog sve veće rasprostranjenosti i nemogućnosti potpunog uklanjanja već samo ublažavanja njihove pojave u kukuruzu i negativnog djelovanja na mliječne krave. U ovom revijalnom radu prikazana su svojstva toksikogenih Aspergillus plijesni koje proizvode aflatoksine na kukuruzu, uvjeti koji pogoduju razvoju toksinogenih plijesni, svojstva plijesni, metode ublažavanja s naglaskom na hranidbena uklanjanja aflatoksina.U literaturnom pregledu prikazani su znastveni rezultati djelovanja organskih vezača (glina), anorganskih vezača (aktivni ugljen), organskih kiselina (propionska) te biološki načini (enzimatska razgradnja aflatoksina).
Ublažavanje pojave i djelovanja aflatoksina na mliječne krave upotrebom aditiva daje promjenljive rezulate te su potrebna daljnja istaživanja kako bi se utvrdilo točno djelovanje.

Abstract (english)

Aflatoxins are one of the biggest threats in the feed production because of the increasing
prevalence and the impossibility of completely removing but only reducing their occurrence
in corn and negative effect on dairy cows. In this review toxigenic properties of Aspergillus
molds that produce aflatoxins in corn are shown, conditions that officiate development of
toxinogenic mold, molds properties, methods of reducing with emphasis on nutritional
removal aflatoxins. The literature review presents the scientific results of the action of
organic binders (clay), inorganic binders (activated carbon), organic acids (propionic) and
biological methods (enzymatic degradation of aflatoxin).
Mitigating the occurrence and effect of aflatoxins on dairy cows by using additives shows
variable results and will need further research to determine the exact effect.
