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®B12 is a rumen-protected microencapsulated form of Vitamin B12 for high yielding dairy cows and ruminants.


Vitamin B12 plays a key role in many metabolic pathways (trans-methylation, gluconeogenesis, beta-oxidation of fatty acids) involved in energy and protein metabolism of the transition dairy cow.
Vitamin B12 in Microtinic®B12 is microencapsulated in a lipid matrix in order to by-pass the rumen and be highly available at the intestinal level.
Once in the intestine, the lipases start to digest the lipid matrix, releasing vitamin B12 and making it available for absorption. Vetagro’s technology assures that vitamin B12 is absorbed within the small intestine due to the tailored particle size.
The protection of Microtinic®B12 is adapted to the digestive transit time of ruminants.

    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.
