Encapsulated Technology Changing The Way Dairy Cows Are Fed

Methionine is one of the two most limiting amino acids for milk and milk component production in U.S. dairy diets. Forages, feedstuffs. and dietary intakes are extremely variable in the amount of metabolizable methionine that can negatively impact milk and milk component production.

MetiPEARL™ is a cost-effective source of rumen bypass and intestinally available methionine for use in dairy cattle. Balancing for methionine using a rumen protected form can help optimize production and allow for greater flexibility when formulating rations. MetiPEARL is encapsulated using the company’s proprietary MicroPEARLS® process that delivers the nutrient to the right place, at the right time.

Keys for selecting the best rumen protected methionine

To effectively evaluate rumen protected methionine available on the market, Kemin recommends examining the following product characteristics:

  • Methionine concentration = Percent (by weight) of the product that is methionine.
  • Rumen bypass = Percent of the methionine contained by the product that is undegraded in the rumen.
  • Intestinal availability = Percent of undegraded methionine in a form available for absorption in the intestine of the animal.
  • Metabolizable methionine (MP methionine) = Percent of the total methionine contained in the product available and utilized by the animal.
    (100% x Bypass % x Intestinal Availability % = Metabolizable Methionine %).

See Figure 1 for a comparison of rumen protected methionine products available in the market.

Delivering the same nutritional value at a lower cost

High rumen bypass alone does not deliver an adequate volume of available methionine to the cow. Each characteristic (methionine concentration, rumen bypass, intestinal availability, and metabolizable methionine) must be taken into account when determining which product provides the most cost effective supply of MP methionine. When taking all of these characteristics into account, MetiPEARL is a cost-effective source of MP methionine.

See Table 1 for a price comparison of the rumen protected methionine products available in the market.
