The influence of contamination with separate mycotoxins (aflatoxins,
ochratoxin A, citrinin, patulin, penicillic acid or sterigmatocystin) on the in
vitro dry matter and organic matter digestibilities of some roughages (berseem
hay and wheat straw).

In vitro study on berseem hay and wheat straw was undertaken to investigate the
the effect of mycotoxin contamination on dry matter and organic matter
digestibilities. The data revealed a negative effect of most studied mycotoxins
on the materials digestibility. Among the investigated mycotoxins, penicillic
acid with its two concentrations (5 and 10 nmol) was the most negative,
affecting digestibilities of both feed materials. Wheat straw digestibility was
more influenced than berseem hay by the ochratoxin A, citrinin and
sterigmatocystin (besides the penicillic acid) particularly with their high
level (10 nmol). Yet, some mycotoxins act as antibiotics which may affect only
the harmful flora but encourage the rumen microflora resulting in slight
improvement of digestibility. The rumen conditions were able to metabolize or
deform the used levels of all mycotoxins studied. Thus, there were no detectable
residues of these mycotoxins in the digestion media after the in vitro
fermentation.
