PHN® GI Pro3
PHN® In collaboration with the scientists at Kemin® Industries, have created a proprietary probiotic designed for targeted gut support.
- Probiotics are live microorganisms that provide a health benefit to the host.
- GI Pro is a multi-strain probiotic/proteobiotic of 3 Bacillus spores that produces molecules that confer unique health benefits.
- GI Pro , in laboratory tests, has been shown to destroy disease causing bacteria including: Clostridium difficile, Clostridium perfringens, Rodococcus equi, Streptococcus equi and Salmonella.
- These disease causing bacteria result in an array of symptoms in the horse including: respiratory discharge, loose manure, diarrhea, lung abscesses and microbiome dysbiosis.
- PHN and Kemin extensively tested GI Pro . It has the ability to survive the heat of feed manufacturing, the acid conditions of the equine stomach and has an extended shelf-life. GI Pro is a true probiotic that arrives to the hindgut alive with proven equine pathogen inhibition.
This probiotic, called GI Pro3, is available only to PHN® clients.
