Summary
In organic animal feeds, the use of genetically modified organisms is prohibited. Therefore, B-vitamins have to be produced with alternative, more expensive strains of microorganisms and the dosage of added riboflavin is economically relevant. Since riboflavin requirement data for poultry are comparably old, the requirements for laying hens with a typical organic diet were reassessed. The aim was to find safe lower thresholds of riboflavin supplementation without impact on animal health and performance.
The addition of 3 mg Riboflavin per kg feed was found safe for organic laying hens.
