        abstract = {This practice abstract provides recommendations for organic poultry systems to meet the Vitamin B2 needs of the animals. Data from project experiments indicate that hens in or- ganic systems can be supplemented with a maximum level of 4.0 mg/kg feed without impacting the performance and animal health of the hens and their offspring. This level of supplementation is lower than the 5-7mg/kg feed recom- mended by Blum et al. (2015).
This tool is recommended for organic poultry farmers across Europe.},
