Rumen bypass amino acids

NaviMino®

 Rumen bypass amino acids improve protein efficiency

Amino acids are essential for the cow’s metabolism, especially around calving. They play key roles in liver function, energy metabolism, immune resilience, and reproductive performance. Two of the most critical amino acids for dairy cows are lysine and methionine.

During the dry period and early lactation, the cow faces intense metabolic demands: the unborn calf grows rapidly, colostrum is produced, and the cow prepares for a new lactation. Supplying coated amino acids that reach the small intestine is crucial to help te cow make this transition smoothly.

  • Methionine supports fat metabolism and liver function, helping to reduce the risk of fatty liver and negative energy balance.

  • Lysine is important for immune function, hormone regulation, and muscle maintenance. 

Why use NaviMino?

Coated amino acids are essential for ruminants to ensure key nutrients bypass rumen degradation and are absorbed efficiently in the intestines. This improves protein efficiency, and reduces the need for excess dietary protein, making it a smart choice for both performance and sustainability.

Improve both performance and sustainability, use NaviMino.

Transform your livestock nutrition today

By supplementing with NaviMino:

  • You support the metabolic health of the cow;

  • You optimize amino acid balance without raising crude protein levels;

  • You promote better feed efficiency and stronger performance;

Benefits of NaviMino

  • Delivers the amino acids where they are needed: In the intestines.
  • High quality products: Proper coating provides product protection and ensures they bypass the rumen.
  • Improved digestion and nutrient absorption: With NaviMino’s efficient protein strategy, more amino acids become available in the intestine — supporting better digestion and overall nutrient uptake.
  • Increased feed efficiency: By minimizing degradation and maximizing uptake of essential amino acids.

Coated Methionine

Supplies the cow with methionine in the intestines

NaviMino® Met is protected methionine. In ruminants unprotected methionine is largely degraded in the rumen before it reaches the site of absorption: the small intestine. Coating allows methionine to:

  • Bypass the rumen.

  • Be released in the small intestine, where it can be effectively absorbed.

Liver function and fat metabolism

Energy balance around calving

Milk yield and milk protein content

Coated Lysine

Supplies the cow with lysine in the intestines

NaviMino® Lys is protected lysine. In ruminants unprotected lysine is largely degraded in the rumen before it reaches the site of absorption: the small intestine. Coating allows lysine to:

  • Bypass the rumen.

  • Be released in the small intestine, where it can be effectively absorbed.

Immune function and hormone regulation

Colostrum quality and reproductive performance

Protein synthesis for growth and lactation
