Probiotics in Animal Health

The use of probiotics for farm animals has increased considerably over the last 15 years. Probiotics are defined as live microorganisms which can confer a health benefit for the host when administered in appropriate and regular quantities. Once ingested, the probiotic microorganisms can modulate the balance and activities of the gastrointestinal microbiota, whose role is fundamental to gut homeostasis. It has been demonstrated that numerous factors, such as dietary and management constraints, can strongly affect the structure and activities of the gut microbial communities, leading to impaired health and performance in livestock animals. Probiotic microorganisms, which benefit from a ‘natural image’, can expect a promising future in animal nutrition. Controlled research studies demonstrate that they can positively balance gastrointestinal microbiota, and thereby improve animal production and health. However, care must be taken in the way that the probiotic candidate-strains are selected. Better knowledge of the structure and activities of the gut microbiota, functional interactions between gut microbes and interrelationships between microbes and host cells represent a fundamental aspect of future probiotic research. In this context new ‘omic’ technologies will be very helpful to better characterize and understand the effects of probiotics on the balance of the gastrointestinal microbiota. It will be possible to select more powerful or targeted strains on a scientific basis and follow their behaviour in the host animal. Thanks to these techniques, which are complimentary to anaerobic culture methods and gnotobiotic animal or cellular models, probiotic research has had, and will also certainly have in the future, a very important place in the improvement of animal health and nutrition.
