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.


Rumen-protected microencapsulated choline for high yield dairy cows.


Choline is one of the key nutrients to maintain liver functionality. Shortage of choline during transition phase can cause a reduction of liver efficiency.

Ruprocol® contains available choline to counteract this shortage condition. As free choline is almost completely destroyed in the rumen by the activity of the microflora, choline in Ruprocol® is microencapsulated in a lipid matrix and can by-pass the rumen and can become available at the intestinal level. A correct management of the liver metabolism can contribute to improve milk production and milk quality.

    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.
