Supplement protects pigs against in-feed viruses, study says

Recent trials suggest that pigs consuming feed supplemented with pHorce, from manufacturer Anpario, were protected against in-feed viruses, had lower mortality and significantly increased average daily gain.

The study, carried out by the Pipestone Applied Research Facility in the US, found that pigs fed the infected control diets showed clinical symptoms of Seneca virus (SVA), porcine reproductive and respiratory syndrome virus (PRRSV) and porcine epidemic diarrhoea virus (PEDV).

However, no evidence of SVA or PRRSV infection was seen in pigs consuming feed supplemented with pHorce.

“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 has 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.”

During the trials, feed was infected with the viruses using Dr Dee’s innovative ice block model, where pigs are offered either the infected feed with no additives, or the infected feed supplemented with the additive, one of which was pHorce, included at the rate of 3kg/t of feed.

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.

Anpario says pHorce is fast acting with rapid acid release helping reduce pathogen load and supports the development of a well-balanced and diverse gut microbiome for optimal livestock health and performance.
