Résumé
Vitamin B2 (Riboflavin) from GMO-free sources is needed in organic poultry feeding. Recently, a serious delivery gap for this vitamin occurred, which shows the necessity to develop new ways of GMO-free Vitamin B2 production. Solution To reduce feed production costs and dependency on external sources, it would be part of a solution if recommended levels of Vitamin B2 supplementation for several types of animals can be decreased. Controlled experiment In a controlled feeding experiment, we tested the reduction of Vitamin B2 supplements down to 66% or even 33% of the recommended level for laying hens. We added either 4.5, 3.0 or 1.5 mg per kg feed to 3 groups per treatment with 15 hens each. The experiment lasted for 18 weeks.
