KESSENT® – Rumen-Protected Methionine for Precision Nutrition

What is Rumen-Protected Methionine and Why Does It Matter?

In ruminant animals, Methionine is a vital amino acid—but much of it is broken down by rumen microbes before it can be absorbed and utilised. Rumen-protected Methionine solves this challenge by using encapsulation or analogue technology to shield the nutrient as it passes through the rumen, allowing it to reach the small intestine intact. This targeted delivery improves protein efficiency, supports metabolic health, and enables more precise feed formulation. For nutritionists focused on performance and sustainability, rumen-protected Methionine is essential to unlocking better milk yield, fertility, and nitrogen utilisation.

KESSENT® Product Line – Tailored Solutions for Targeted Nutrition

KESSENT® Me – Encapsulated Methionine for High Bioavailability

KESSENT Me is a high-performance Methionine formulation designed for maximum intestinal absorption. Using advanced encapsulation and particle engineering, it ensures Methionine escapes rumen degradation and reaches the small intestine where it can be effectively utilised.

This solution is ideal for nutritionists focused on precision, especially during the close-up period, when Methionine supplementation has the greatest impact on milk yield, fertility, and metabolic health.

KESSENT® MF – High-Concentration HMBi for Industrial Feed Applications

KESSENT MF is a Methionine analogue offering the highest concentration of 2-Hydroxy-4-Methylthio-Butanoic Isopropyl Ester (HMBi) available for ruminants. Designed for industrial feed manufacturers and large-scale operations, it provides a cost-effective, automated approach to Methionine supplementation.

Available in Dry, Liquid, and Arome Dry formats, KESSENT MF integrates seamlessly into existing feed systems and supports clean label, scalable nutrition strategies.
