Study shows Anpario’s pHorce helps protect pigs against in-feed viruses

22 August 2020, at 7:00am

A recent study, conducted by Dr Scott Dee at Pipestone Applied Research Facility in the USA, has been undertaken to test the anti-viral efficacy of widely available feed additives.

Pigs were challenged with Seneca virus A (SVA), porcine reproductive and respiratory syndrome virus (PRRSV) and porcine epidemic diarrhoea virus (PEDV). The feed was infected with these viruses using Dr Dee’s innovative ice block model and pigs were offered either the infected feed with no additives, or the infected feed supplemented with the additive, one of which was pHorce, included at 3kg per tonne of feed.

Whilst the pigs fed the infected control diets exhibited clinical symptoms of SVA, PEDV and PRRS, no evidence of SVA or PRRS infection was observed in the pigs consuming feed supplemented with pHorce. In addition, it was found that pHorce lowered mortality and significantly increased average daily gain compared to pigs from the control group.

“To find that pHorce, which is formaldehyde free, not only delivers effective anti-bacterial and anti-fungal action, but also successfully protects feed with proven anti-viral activity at a relatively low inclusion is massively important”, said Dr Wendy Wakeman, Anpario’s Global Technical Director. “This finding will help in ensuring the biosecurity and safety of future feed and livestock production.”

“Anpario have worked with Acid Based Eubiotic (ABE) feed additives for more than 30 years with a particular focus on pathogen control”, added Dr Wakeman. “The proven anti-viral activity of pHorce, specifically in the mitigation of the effect of PRRS, PEDV and SVA, highlights the effective triple action of the feed additive, which is also a well-established anti-bacterial and anti-fungal product.”

Manufactured by UK-based, independent feed additive producer Anpario, pHorce is developed from a concentrated synergistic blend of formic and propionic acid formulated on a unique carrier system for optimal efficacy. It is a free-flowing dry powder which is easily dispersed within raw materials and finished feed. pHorce is fast-acting with rapid acid release helping to reduce pathogen load and support the development of a well-balanced and diverse gut microbiome for optimal livestock health and performance.
