The Basics

Amino acid balancing is key to sound nutrition.

Amino acids are the building blocks of protein — one of the most important aspects of dairy nutrition and critical to making milk. Dairy cows cover their daily amino acid requirements through common protein sources such as alfalfa, hay or soybean meal. This “crude” protein is simply a composite of different amino acids.

Amino acids supplied at levels below requirements limit milk production. The two amino acids most commonly limiting are methionine and lysine. It is absolutely necessary that these amino acids make up a certain portion of dietary protein content. Without them, dairy cows simply cannot produce at their potential.

Ideally, supply and requirements for each amino acid would match each other identically. However, the amino acid composition of milk protein differs from that of feed ingredient protein. This mismatch often results in amino acid content of dairy rations being “out of balance” — resulting in production and/or profit inefficiencies.

 

Mepron® provides the nutritional requirements dairy cows need to improve milk production.

 

Methionine is one of ten amino acids essential for dairy cows to maintain optimum health and productivity. Dairy cows acquire the methionine they need through their diet and from digesting microbes washed out of the rumen. Compared to other methionine sources, Mepron® carries a high payload—85% methionine—to deliver this crucial nutrient to the cow. Rumen stability ensures that the proper levels of methionine reach their appropriate destinations. Methionine is required in both the rumen—for the growth of microbes—and the small intestine—for direct use by the cow in the production of milk.

Mepron® is designed to release 15% to 20% of the methionine in the rumen. The remainder is absorbed along the small intestine. Mepron®‘s rumen stability and intestinal availability have been studied and confirmed by many laboratories..

Methionine is not only built into body and milk protein, but is also an important part of enzyme systems that enable cows to get energy from feed. It’s also a component of the immune system, keeping body membranes healthy. Insufficient methionine can impair herd health and diminish reproductive efficiency. This deficiency may also prevent dairy herds from producing to their fullest potential.
