The rumen is the site of significant interactions between Cu, S and Mo. It also shows reactions between Cu, S and Fe. The interaction between Mo and S results in the formation of thiomolybdates, which in the absence of adequate quantities of rumen Cu are absorbed into the animal and bind to Cu in biological compounds. This is the cause of thiomolybdate toxicity, often misleadingly called Cu
Molybdenum deficiencies are characterized by symptoms similar to sulfur toxicity. Molybdenum supplementation is unnecessary. Due to the lack of evidence and very low risk of deficiency, molybdenum may not even need to be added to multivitamin formulas.

Molybdenum toxicity is linked closely with its interactions with sulfur and copper, though these interactions differ among species, as ruminants are much more sensitive to high molybdenum intakes than horses. A study in horses found that molybdenum at 20 mg/kg of the diet did not affect the absorption or utilization of copper. This intake level is much higher than the levels reported to affect

Their rumen is the site of high sulfide generation, and the interaction of molybdenum with sulfur results in the formation of thiomolybdates. Tetrathiomolybdate, a thiomolybdate with four sulfur atoms, can form complexes with copper preventing its absorption and blocking the activity of copper-dependent enzymes.

The findings that dietary molybdenum and sulfur significantly increase copper excretion through the biliary and urinary routes are in agreement with the reported beneficial effects of molybdenum and sulfur in the treatment of copper-toxicity in sheep.
Molybdenum (Mo) is one of the six ‘minor’ chemical elements required by green plants. The other five are iron, copper, zinc, manganese and boron. These elements are termed ‘minor’ because plants need them in only very small amounts (in comparison with the ‘major’ elements nitrogen, phosphorus, potassium, sulfur, calcium and magnesium). But they are essential for normal growth. Of
