What makes a good probiotic?
- Safety - the microorganism chosen as the components of a probiotic must be non-pathogenic and non-toxic
- Viability – a probiotic can only work if the microorganisms contained within the probiotic remain viable during storage of the product and through the gut to ensure colonisation of these microorganisms
- Minimum requirement – the concentration of a probiotic must be such that inclusion rates provide 107 – 108 CFU per animal
- Quality insurance – it is essential that a probiotic has not become contaminated with any other microorganism others than the particular probiotic microorganisms chosen at any stage e.g. fermentation, of the manufacturing process or during storage.
