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 40 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.


AviPremium®  is a complete range of products based on tributyrin, a triglyceride of butyric acid that promote the intestinal mucosa trophism.


AviPremium® Ruminants products are based on tributyrin, a triacylglycerol of butyric acid (EU Reg. 1831/2003; FDA 21 CFR 184.1903).
Tributyrin is the most concentrated derivate of butyric acid on the market. The tributyrin in it is more stable and has superior organoleptic characteristics than butyric acid. AviPremium® Ruminants products are an alternative to Na-butyrate. In AviPremium® Ruminants, the butyric acid from tributyrin is chemically protected and delivered where butyric acid can be effective. The esterification with glycerol allows the butyric acid to be released in the intestine due to the action of pancreatic lipases. The microencapsulation of it allows further advantages and efficacy at the intestinal level.


The full range of products is composed of: AviPremium® L based on liquid tributyrin (85% butyric acid). AviPremium® D, a concentrated source of tributyrin in powder form (55% butyric acid). AviPremium® S and P where the tributyrin is microencapsulated within a vegetable lipid matrix according to the digestive characteristics of swine and poultry respectively (25% butyric acid).

    Intestinal health: organic acids and pure botanicals can be extremely useful

    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.

    Thymol as an Adjuvant to Restore Antibiotic Efficacy and Reduce Antimicrobial Resistance and Virulence Gene Expression in Enterotoxigenic Escherichia coli Strains

    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.

    Dual Antimicrobial Effect of Medium-Chain Fatty Acids against an Italian Multidrug Resistant Brachyspira hyodysenteriae Strain

    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.
