In this episode of The Food Files, Patrica Rayas, FAPC cereal chemist, discusses how her research is unleashing the potential of fermented grain systems. Probiotics have beneficial effects in the digestive system of humans, pets and farm animals. In Dr. Rayas' study, fermented grain products like sourdough were used as a source of bacterial strains with potential digestive health benefits in chickens. Chickens in the probiotic group had more efficient feed conversion ratio up to 4 weeks old. Birds receiving probiotics supplements coped better when subjected to heat stress compared to the control without probiotics.
