Abstract

Sodium tungstate added to rumen fluid depressed the nitrate reductase activity of rumen microbes. The rate of nitrite formation in rumen fluid fell by about 86% if 20 mu mol of Na2WO4 were added per litre. At 100 and 500 mu mol/l no nitrite accumulation was observed. This inhibition was overcome by molybdenum. Experiments in cows confirmed these in vitro findings. Tungsten is suggested as a promising preventative of nitrite intoxication in ruminants.
