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®PP is a rumen-protected microencapsulated form of Vitamin PP (Nicotinic Acid) for dairy cows and ruminants.


Nicotinic acid elicits vasodilatory actions that may be beneficial for cows under heat stress. Supplementation of nicotinic acid during the transition period and in fresh cows may be useful in reducing plasma NEFA concentration due to its anti-lipolytic effect.
Supplementing nicotinic acid as Microtinic®PP avoids ruminal degradation of niacin. 1g of Microtinic®PP provides the same amount of nicotinic acid at the intestinal level as 3.75g of free nicotinic acid.


Niacin in Microtinic®PP 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 niacin and making it available for absorption.
Vetagro’s technology assures that niacin is absorbed within the small intestine due to the controlled particle size. The protection of Microtinic®PP 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.
