The need to guarantee ruminant absorption of a correct amount of nutrients in the intestine cannot disregard the degradation by the rumen microflora. For over 30 years our scientific research has set the goal to improve the rumen bypass so that a lower concentration of active ingredients in the diet leads to maximizing performance.


Timet® contains 55% of rumen-protected microencapsulated DL-Methionine.


Despite methionine is essential for maximal milk production, unprotected methionine is rapidly and extensively degraded by rumen microorganisms before it passes to the small intestine for absorption. In order to deliver available methionine to ruminants strategies that protect the amino acid from rumen degradation are needed.
Methionine in Timet® is microencapsulated in a lipid matrix in order to by-pass the rumen and be highly available at the intestinal level. Different studies demonstrated that Timet® increased plasma methionine concentrations. It optimizes nitrogen metabolism of the dairy cow and improves milk protein yield. Timet® if used alone or in combination with Relys® allows to obtain an amino acid balanced ration so to maximize milk and milk solids output.


Nutritional evaluation of Timet® is available for nutritional software based on the dynamic models (CNCPS and CPM). The degree of rumen by-pass of Timet® has been certified by independent research institutes applying the in-vivo nylon bags technique and availability in plasma.

    Methionine is considered the most limiting essential amino acid for ruminants (Schwab & Broderick, 2017). This element has a pivotal role in their productive performance and nitrogen efficiency.

    Our findings in Holstein calves are early evidence that dietary microencapsulated OA/PB feeding is a means to partially restore feed intake and average daily gain post-weaning when challenged by heat exposure.

    Heat stress develops with methyl donor deficiency in parallel with an impaired N metabolism. The supplementation of OA/PB improves the remethylation capacity in the liver. On-going transcriptomic analyses will provide a better understanding of the hepatic metabolism of dairy cows exposed to heat stress.
