Metabolism of aflatoxin, ochratoxin, zearalenone, and three trichothecenes by intact rumen fluid, rumen protozoa, and rumen bacteria.
The effect of rumen microbes on six mycotoxins (aflatoxin B1, ochratoxin A, zearalenone, T-2 toxin, diacetoxyscirpenol, and deoxynivalenol ) considered to be health risks for domestic animals was investigated. The mycotoxins were incubated with intact rumen fluid or fractions of rumen protozoa and bacteria from sheep and cattle in the presence or absence of milled feed. Rumen fluid had no effec...

متن کاملProtease activities of rumen protozoa.
Intact, metabolically active rumen protozoa prepared by gravity sedimentation and washing in a mineral solution at 10 to 15 degrees C had comparatively low proteolytic activity on azocasein and low endogenous proteolytic activity. Protozoa washed in 0.1 M potassium phosphate buffer (pH 6.8) at 4 degrees C and stored on ice autolysed when they were warmed to 39 degrees C. They also exhibited low...
متن کاملRumen Protozoa - Potential for Manipulation
The manipulation of rumen function through the removal of the ciliate protozoa has not resulted in consistent changes in ruminant production. Current research findings are discussed with particular emphasis given to the role of protozoa in fibre digestion in the rumen and the availability of protein for intestinal digestion. Dietary conditions under which positive responses to defaunation can b...
