| Abstract: | In comparison to monogastric species, ruminant animals are generally considered to be less susceptible to the adverse effects caused by contamination of feeds with mycotoxins. This is based on the assumption that the rumen flora degrade and inactivate mycotoxins, thus protecting the animal. A number of mycotoxins, however, resist rumen degradation, causing distinct clinical signs of intoxication. Moreover, due to their complex diet, dairy cows may be exposed to a varying number of mycotoxins, originating from different feed materials such as roughage and concentrates. Exposure to these complex mixtures of mycotoxins may result in unexpected health risks. Due to a pre-existing negative energy balance, cows in the transition period are considered to be particularly sensitive to the exposure to feeds contaminated with moulds, fungal spores and mycotoxins. |
