The Science, Microbes & Health Podcast
This podcast covers emerging topics and challenges in the science of probiotics, prebiotics, synbiotics, postbiotics and fermented foods. This is the podcast of The International Scientific Association for Probiotics and Prebiotic (ISAPP), a nonprofit scientific organization dedicated to advancing the science of these fields.
Prebiotics for animal health, with Prof. George Fahey
The hosts discuss prebiotics for animals with Prof. George Fahey, a prominent animal nutrition scientist who is currently Professor Emeritus at University of Illinois. Fahey explains how animal nutrition research relates to human nutrition research, and the changes in the field he has seen over the course of his long career. He describes the research on prebiotics for animal nutrition, covering both livestock and companion animals.
Key topics from this episode:
- A short history of animal prebiotics research as well as future opportunities in animal nutrition.
- Pro- and prebiotics are being explored as an alternative to antibiotic treatment in production animals. Antibiotics are overused, leading to an increase in antibiotic resistance; the “biotics” therefore have great potential in animal nutrition.
- Probiotics can potentially be used instead of antibiotics to inhibit pathogens and support the gut microbiota in animals.
- Prebiotics possibly have high nutritional value and beneficial effects in animals, especially in poultry and pigs.
- There are limitations to using prebiotics in the animal industry, especially for some animals such as horses and ruminants.
- There has been increased use of prebiotics for companion animals (pets) in the past few years. Now many pet foods contain prebiotics.
- Benefits of using prebiotics in companion animals:
- Support digestive health
- Improve stool quality
- Support the gut microbiota, which also translates to good stool quality
- A short overview of how companion animals’ food is produced, and the timing of adding prebiotics.
- Wild animals’ diet has low nutrition with limited to no prebiotic intake, resulting in a shorter lifespan in comparison with companion animals
- Some take-home points from animal models and animal nutrition research.
