Livestock Science, a peer-reviewed journal, promotes the livestock sector’s sound development by featuring articles on all aspects of animal production. Next month’s issue will feature new research from Novus International, in partnership with the University of Bologna and the Universidad Complutense de Madrid.

The study, titled “Effect of dietary supplementation with a blend of protected aromatic compounds, including benzoic acid, on growth performance and faecal microbial profile of weaned piglets as an alternative to zinc oxide (ZnO)”, sheds light on how feeding piglets with Novus’ PROVENIA feed supplement can positively influence piglet gut health and performance, while improving their feed conversion rate.

The research concluded that supplementation with PROVENIA positively influenced the microbial profile of weaned piglets. The supplement increases alpha diversity and favours the proliferation of known beneficial bacteria related to the metabolism of polysaccharides and production of short-chain fatty acids.

These findings on the faecal microbial profile explain the higher average daily gain and lower feed conversion rate observed in piglets supplemented with PROVENIA.

PROVENIA is a combination of embedded aromatic compounds, including benzoic acid as the main component, in a fat matrix, allowing the active compounds to reach the distal gastrointestinal tract compartments, thus improving the growth of naturally producing butyric acid bacteria in piglets.

Starting in 2022, using pharmacological levels of ZnO in animal diets will be banned by the European Commission. Dr Marisol Castillo, Novus senior technical services manager: swine, North Europe, who conducted the studies, said: “The study demonstrates the efficacy of PROVENIA in the post-weaning period as an alternative strategy to ZnO. It also shows remarkable beneficial effects on gut microbiota of the piglets.”
