Takeuchi-Storm, et al (2024) Effect of Feeding BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

A recent study published in Poultry Science explores the potential of feed and water additives to reduce Campylobacter—a leading cause of foodborne illness—in free-range broilers. Researchers tested four interventions: biochar, oat hulls, yeast fermentate, and organic acids, assessing their effects from hatching to slaughter.

Free-range broilers, often exposed to outdoor environments, are particularly prone to Campylobacter contamination. The study, conducted on a commercial farm, involved 140 broilers divided into groups receiving different additives, with comparisons to a control group on standard feed. Campylobacter levels were measured at 36 and 59 days.

Results showed that biochar significantly reduced Campylobacter counts by 0.70 log10 CFU/g at slaughter age (day 59), making it the most effective long-term intervention. Organic acids in drinking water lowered Campylobacter by 0.62 log10 CFU/g at 36 days, though the effect diminished by 59 days. Neither oat hulls nor yeast fermentate significantly reduced Campylobacter levels.

Biochar, a carbon-rich material, may influence gut bacteria, creating unfavorable conditions for Campylobacter. Organic acids potentially alter the gut environment, though their effect appears to be time-sensitive. Importantly, no adverse effects on bird health or growth were noted.

This research highlights biochar as a promising tool for reducing Campylobacter in free-range broilers. Further studies are needed to refine application timing and confirm efficacy across different farm conditions. Effective interventions like these can help enhance food safety while supporting sustainable poultry production.
