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


Tetracid®S is the 2nd generation of Vetagro products for pigs. A synergistic microencapsulated blend of organic acids and nature-identical compounds.


Tetracid®S is the 2nd generation of Vetagro innovative products for swine. The efficacy of Tetracid®S on improving performance in swine is due to the synergistic effect of its components: organic acids and flavouring compounds. The antibacterial power of the acids is enhanced by the disruptive action of flavouring compounds on the bacterial membrane.


The protective matrix of Tetracid®S allows the active nutrients to by-pass the stomach reaching the small intestine. The release is adapted to the transit time of swine gastrointestinal tract.

Microencapsulation technology makes Tetracid®S a product safe and easy to handle, being non-corrosive.

    The impact that a molecule can have on animal metabolism and physiological functions is strictly linked to different modes of action of the molecule itself. These activities must be studied and well known to use the nutrition favoring both animal health and production effectively.

    The aim of this study was to investigate the potential adjuvant effect of thymol to re-establish antibiotic efficacy against highly resistant ETEC field strains. Secondly, we evaluated the modulation of virulence and antibiotic resistance genes.

    In this study we tested four antibiotics (tylosin, lincomycin, doxycycline, and tiamulin) and medium-chain fatty acids (MCFA; hexanoic, octanoic, decanoic, and dodecanoic acid) against an Italian field strain of B. hyodysenteriae and the ATCC 27164 strain as reference.
