Aflatoxins are metabolites produced by mold fungi such as Aspergillus flavus and A. parasiticus under certain conditions. The most abundant aflatoxin, aflatoxin B1, is a potent carcinogen and it is considered the most toxic naturally occurring toxin.

Essentials oils are volatile aromatic compounds with an oily appearance extracted from plant materials typically by steam distillation. Traditionally, they have been used in dairy diets to modify ruminal microflora and alter rumen fermentation. Recent research; however, shows the implication of some essential oils on physiologic functions in the cows…
