Relys® 50

Relys®50 is a microencapsulated lysine source designed to bypass ruminal degradation and deliver lysine efficiently to the intestine. It is ideal for precision amino acid balancing in ruminant nutrition.Relys®50 stands out through its scientifically validated mode of action and versatile use on farms or in feed mills. By supporting increased plasma lysine and methionine levels, Relys®50 allows producers to optimize nitrogen efficiency, increase protein and casein yields, and reduce urea excretion—while sustaining or improving milk volume, composition, and farm profitability.

Microencapsulation is key to the efficacy of Relys®50. Its lipid matrix ensures that lysine is protected from rumen microbes and released where it matters most—at the intestinal level.
Lipids provide rumen protection, ensures controlled intestinal release and high bioavailability, maintains stability during pelleting and mechanical processing and guarantees consistent nutrient delivery for high-performing animals.

Key benefits 

• Improves nitrogen efficiency and reduces urea excretion

• Increases income through better feed efficiency and nutrient utilization
• Promotes sustainability by reducing nitrogen losses
• Rumen-protected lysine with high intestinal bioavailability
• Scientifically proven bioavailability and performance
• Ideal partner for methionine sources such as Timet®
• Compatible with premix and TMR formulations

Recommended use

• Dairy cows: 15–100 g/head/day from 30 days before to 200 days after calving

• Sheep and goats: 1–10 g/head/day from 15 days before to 60 days after calving
