Wethers equipped with a rumen fistulae were subjected to four dietary treatments in consecutive experiments.The treatments consisted of rations containing wheat grain and pasture hay at a of 1 to 1 on a dry matter basis. Two wheat grain batches were fed either in abscence or presence of a detoxyfying agent. One wheat grain batch served as the uncontaminated control wheat whereas the other batch contained the Fusarium toxins deoxynivalenol (DON) and zeralenone (ZON). It can be concluded that feeding of rations containing approximately 4.6 mg of DON and 0.34 mg ZON per kg of complete ration at a reference dry matter content of 88 percent does not impair rumen fermentation although there was a trend for a decrease in the rate of dry matter degradation of the slowly degradable wheat straw. The pH-buffering effects of the detoxyfying agent were mycotoxin independent
