Rumen By-pass Methionine


High yielding dairy cows have a high demand for energy and protein. The first limiting amino acids for high productive dairy cattle are methionine and lysine. Dairy cows are fed protein rich feeds in order to meet their metabolizable protein requirement. The amino acid profile of feeds is a determining factor in the metabolizable amino acid supply and should be as close as possible to the ideal AA-profile of milk. Protein rich feedstuffs such as soybean meal have a relatively low methionine content in comparison towards lysine. There is a need for protected methionine as a source of metabolizable methionine.

Free methionine will be degraded in the rumen, coating methionine with fat is one way to protect methionine for rumen degradation and comes available for absorption in the small intestine. Innovad special coating technique is based on advanced technology involving synchronized spray cooling of a composite matrix of primarily selected long chain fatty acids. This technique assures that the maximum amount of protected nutrients is able to by-pass rumen fermentation and remains available at the small intestine. The coating protects nutrients from oxidation, pH, light and makes the product free flowing and non-hygroscopic.


Novimet facilitates the ration formulation so that the animal can meet the metabolizable methionine requirements without the excess of protein that usually occurs with conventional feedstuffs. That leads to increased milk production with optimal components levels and lower nitrogen excretion.
