Summary in the original language of the document

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.

EPrint Type:	Practice tool
Teaser:	Avoid vitamin B2 deficiencies, improve performance and health.
What problem does the tool address?:	Vitamin B2 (riboflavin) is needed as a supplement in poultry diets. In the organic sector, GMO-free sources/supplements are obligatory. New production strains for GMO- free vitamin B2 are being developed in Europe due to recent shortages at overseas producers. Non-GMO sources of vitamin B2 are more expensive than their GMO-based counterparts.
What solution does the tool offer?:	To optimise feed production costs and reduce dependency on external sources, levels of vitamin B2 supplementation in organic production need to be re-evaluated for several types of animals.
