Trial results show Anpario's pHorce effective against Seneca Valley virus in pigs

In an independent trial conducted at Pipestone Applied Research Facility in the United States, pHorce by Anpario was found to be an effective mitigant against Seneca Valley virus, as well as Porcine Epidemic Diarrhoea virus (PEDv) and Porcine Reproductive and Respiratory Syndrome virus (PRRSv).

Seneca Valley virus, also known as Senecavirus A, is a viral disease of pigs which is related to the family of viruses that cause foot-and-mouth disease. Historically, the majority of confirmed cases have been recorded in the US. However, more recently cases of the virus have also emerged in other countries, including England, the United Kingdom, as of 2022.

The virus causes vesicular lesions which usually appear around the coronary band and in or around the snout and nares. Lameness is also commonly reported and crusting of the hoof wall may also be observed.

Whilst the virus is not notifiable or reportable in the UK, nor is it a listed disease by the World Organisation of Animal Health, the clinical signs resemble that of notifiable diseases such as foot-and-mouth disease. This can lead to significant financial losses as a result of temporary closure until notifiable diseases are ruled out, along with reallocation of financial resources towards diagnostic investigation.

In the trial, the triple action feed mitigant pHorce has been shown to be an effective viral mitigant. Pigs were challenged with Seneca Valley virus, PEDv and PRRSv via the feed using an "ice block model".

In pigs fed pHorce supplemented diets, there were no clinical signs associated with any of the viruses compared to the control pigs, where 100% presented clinical symptoms. In addition, there was no evidence of Seneca Valley virus in pigs fed pHorce and supplemented pigs had a lower mortality and an average daily gain which was double that of the control fed pigs.

pHorce is part of Anpario's Acid Based Eubiotic (ABE) range and is a concentrated blend of formic and propionic acid on a unique micropearl carrier delivery system which has been chosen to ensure maximum efficacy during feed manufacture and throughout the gastrointestinal tract of the animal.
