Molybdenum in animal husbandry

The biological role of molybdenum mainly relies on the fact that as a constituent of certain molybdenum-containing enzymes in the animal body, it indirectly affects the biological activity of the enzymes. In addition, molybdenum plays a special role in the nutritional metabolism of ruminants. On the one hand, molybdenum is directly involved in the conversion of feed nitrate in the rumen as a constituent of the rumen microbial nitrate oxidase, and on the other hand, molybdenum has a stimulating effect on the rumen microbes as a cofactor for the sulfate oxidase, which contributes to the digestion of the ruminant's crude fiber-like substances, and thus promotes the ruminant's Growth. Therefore, when the molybdenum content in pasture and feed is insufficient, it is necessary to add molybdenum additives to the feed according to strict nutritional needs and technological requirements to meet the needs of the animals, the most common example being the addition of 10 mg/d of molybdenum to the feed of dairy cows.
