Limosilactobacillus strains improve feed efficiency in broiler chickens through ornithine-mediated gut microbiota modulation and Nrf2 signaling activation (microbiomejournal.biomedcentral.com)

• Duodenal Limosilactobacillus abundance positively correlated with feed efficiency in broilers.
• L. vaginalis LD11 and L. ingluviei CC32 supplementation improved feed conversion and intestinal health.
• Mechanism involves ornithine production and Nrf2 signaling activation to enhance antioxidant capacity and nutrient absorption.

"A study published in Microbiome identified duodenal Limosilactobacillus strains positively correlated with feed efficiency in broiler chickens. Supplementation with L. vaginalis LD11 and L. ingluviei CC32 improved feed conversion, antioxidant capacity, and nutrient absorption. The mechanism involves ornithine production and Nrf2 signaling activation, modulating duodenal microbiota and intestinal function. Findings suggest probiotic interventions could enhance poultry feed efficiency, with potential implications for animal agriculture and microbiome-based feed additives."
