Effect of feeding biochar, oat hulls, yeast fermentate, and organic acids on reduction of Campylobacter in free-range broilers from hatching to slaughter.

ABSTRACT: The Campylobacter prevalence in free-ranging broiler flocks is usually higher than in conventional flocks, and effective interventions for this production type are needed. This study aimed to investigate the on-farm Campylobacter-reducing effect of feeding three feed additives or a water additive to broilers from hatching to slaughter. Newly hatched Ranger Gold broilers (n = 140) were randomly placed into five cages (n = 28/cage) within a flock of 6,000 broilers. The broilers had access to outdoor areas after day 36. Three groups received one of the following feed additives: 2 % (w/w) Biochar Charcoal Feed Granules for Poultry, 0.125 % Original XPC™ (Saccharomyces cerevisiae fermentate), or 15 % oat hulls. One group received organic acids added to water (Selko®pH E 0.2 % (v/v)), and one gr
