rumen-protected DL-Methionine


Mepron® delivers highly concentrated  rumen-protected DL-methionine precisely where it benefits dairy cows most – in the small intestine. For better performance and greater sustainability.

Dairy cow farmers need to efficiently increase milk yield

Amino acids, the building blocks of protein, are essential nutrients in overall metabolism, but particularly critical for dairy cows producing milk. In most dairy cow diets, the first limiting amino acid is methionine. If methionine is missing, the cow is unable to utilize any other amino acids for protein synthesis. This decreases the animal’s performance and the quantity of milk produced. The methionine requirement for optimum milk production can be met in two ways: either by feeding the dairy cow a diet very high in crude protein content, which leads to a surplus of all other amino acids – in turn causing imbalances and inefficient protein use – or by supplementing with DL-methionine. The latter method is superior, yet it demands a high level of precision in meeting all nutrient requirements including methionine. If this is accomplished successfully, the result is optimized nutrient utilization, minimized feed costs and increased milk yield. Additionally, the role of amino acids goes beyond aiding performance, by improving herd health, immunity and fertility.

Reduce nitrogren excretions and increase performance of your dairy cows with Mepron®

Mepron® enables amino acid balancing of dairy rations to meet environmental challenges by reducing nitrogen excretion, while increasing milk yield and quality.

In ruminant nutrition, supplemental amino acids must be protected against microbial degradation in the pre-stomach system (i.e. the rumen). For this reason, Evonik’s DL-methionine supplement Mepron® is equipped with a time-release film coating. Rumen-protected Mepron® delivers methionine in a highly concentrated form, ensuring that the nutrient arrives in the small intestine to be absorbed. Mepron® supplies metabolizable methionine at a lower cost per gram than any form of feed protein. Depending on current raw feed material prices, your ration costs can be reduced by US$ 0.05–0.20 per cow per day. Mepron® is simply the most cost-effective methionine source for dairy rations.
