摘要

Manganese is one of those trace elements that is a vital piece in the dietary jigsaw and ultimately impacts on production. The trace element is involved with the production of the reproductive hormone progesterone, which is initially produced by the corpus luteum and is responsible for maintaining pregnancy. Marginal manganese deficiency has been linked to silent heats, reduced conception rates, abortions and cystic ovaries. But how much do your cows need? Is their diet already providing sufficient levels, or could they actually benefit from a little extra, if provided in a different form? Manganese requirements are in fact a moving target. They can differ significantly between cows, and between herds and stage of lactation. See table 1 for recommended levels.
