In this practice abstract, the four different controlled feeding trials using two riboflavin products at different concentrations showed that the newly available riboflavin product EcoVit R is equally suitable as the conventional one (Cuxavit); and that slow-growing broilers need less riboflavin than the currently recommended amounts for conventional broilers (Blum et al., 2015). Feed supplementation for organic slow-growing broilers is provided at 4.0 mg Vit B2/kg feed.
The practice abstract is recommended for organic farms raising slow-growing broiler chickens
