Why Lysine?

Lysine is critically important for supporting maximum production in dairy cows. Lysine is an essential amino acid and must be supplemented into a cow's diet when typical diets cannot meet her requirements.

When optimal lysine levels are fed, producers can:

  • Feed diets lower in crude protein
  • Achieve more efficient production of milk and milk components
  • Reduce the overall nitrogen excretion from their cows into the environment

Lysine Deficient Diets

Many diets are lysine deficient, especially those that are corn based. It is not possible to provide enough lysine with corn and soybean meal. A nutritionist's goal is to match up the protein source with the cow's lysine requirement.

How Much Is Really Needed?

In 2001, the National Research Council (NRC) conducted a meta analysis and determined the break point for metabolizable (MP) lysine is 7.2%. MP lysine is the amount of lysine passing through the rumen in a form that is available for absorption in the small intestine. This level of MP lysine:

  • Supports maximum milk production
  • Optimizes milk component levels
  • Creates potential for palatability issues when animal-based bypass protein sources such as blood meal and fish meal are fed to meet this level

Why Rumen Protected Lysine?

Rumen protected lysine is a more attractive option than a by-product or commodity because of quality and consistency. Variations in blood meal impact the amount of metabolizable lysine (MP lysine) available to the animal.

Meeting MP Lysine Requirements

Computer software cannot account for feedstuff variability. A half pound of blood meal should provide 20 grams MP lysine, but does it? Average-quality blood meal provides 10 grams less MP lysine than good-quality blood meal.

Only The Lab Can Tell

Test results of blood meal samples from 12 different suppliers showed there was no visual difference between samples. The total lysine (in grams) is fairly consistent across samples.

The variability occurs when you look at MP lysine, which is the amount that actually gets absorbed by the cow.

  • Blood meal contains similar amounts of total lysine
  • MP lysine values differ between blood meal sources
  • Color is not an indication of quality
  • Unable to forecast the amount of MP lysine fed

Why Is Blood Meal So Variable?

Blood meal dried too aggressively prompts a Maillard reaction, which binds lysine.

Why LysiPEARL?

Innovation in amino acid nutrition is changing how cows are fed, improving production and performance. What's changed? Research shows achieving optimal production requires more than rumen bypass. Lysine has little impact on a cow's production if the lysine is not actually absorbed from her small intestine.

LysiPEARL, with its higher levels of metabolizable protein (MP lysine), promotes an efficient use of amino acids because the lysine is more intestinally available to the cow.

Compare Bioavailability

One product delivers on rumen bypass and bioavailability; it's also the most cost-effective MP lysine on the market, LysiPEARL. Created with a proprietary spray freezing process, LysiPEARL maximizes production, and profitability.

  • More bioavailability can result in more milk
  • LysiPEARL is developed for maximum bioavailability
  • To produce more milk, more lysine must be absorbed

Efficacy Proven In All Stages

LysiPEARL technology is supported by data-driven research using sophisticated models that are validated in a three-step process.

More Lysine, More Milk

Kemin field studies show that 10 grams of metabolizable lysine can increase milk production by more than 3 pounds per cow, per day. Click the highlighted state to learn how metabolizable lysine (MP lysine) impacts energy corrected milk.
