The effects of different ruminal parameters such as pH and fementation on the degradation of OA to ochratoxin alpha was investigated under in vitro conditions using the ‘Hohenheimer gas test’. A mixture of ruminal fluid and a culture medium was incubated with OA for 48 hr. The ruminal degradation rate of the toxins was affected by the relation of roughage and concentrate in the complete diet. In diets comprising of 40% roughage and 60% of concentrate the degradation rate was higher than in diets consisting of 100% concentrate. A shorter half life for OA was estimated when starch was added to the medium. The rate of degradation of OA was not significantly effected by pH.
