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 40 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.


Microtinic®B-Complex is a rumen by-pass source of water soluble vitamins for ruminant species.


B vitamins supplied by Microtinic®B-Complex are microencapsulated in a special lipid matrix in order to by-pass the rumen and be highly available at intestinal level.
Once in the intestine, the lipases start to digest the lipid matrix, releasing nutrients and making them available for absorption.
Vetagro’s technology assures that nutrients of Microtinic® B-Complex are absorbed within the small intestine due to the tailored particle size.
The protection of Microtinic®B-Complex is adapted to the digestive transit time of ruminants.


Microtinic®B-Complex is a microencapsulated rumen-protected blend of biotin, folic acid, calcium pantothenate and pyridoxine.
Microtinic®B-Complex supplies key vitamins as important co-enzymes in the metabolism of the dairy cow. B vitamins plays an important role in regulating the energy metabolism, improving the feed efficiency and increasing milk production and quality without affecting the dry matter intake.

    Rumen-protected methionine: a boost for primiparous dairy cows performance

    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.

    Organic acid and plant botanical supplementation in heat-stressed Holstein calves

    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.

    Effects of heat stress and dietary organic acids and botanicals on hepatic one-carbon metabolism

    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.
