Summary

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.
