Investigations on ribofavin production by wild‑type yeast strain for supplementation of organic feed
Supplementation of vitamin B2 (ribofavin) in poultry feeding is essential. For economic and environmental reasons, ribofavin is now produced biotechnologically, which, in most industrial production, is based on genetically modifed organisms (GMOs). Due to legislation, organic animals must be fed with GMO-free feeds, which also applies to the production processes of vitamin additives in the […]
Effects of riboflavin supplementation level on health, performance, and fertility of organic broiler parent stock and their chicks
RELACS – Improving inputs for organic farming – Data from breeder hens and chicks are particularly critical for the development of vitamin B2 recommendations for organic poultry. To test safe thresholds of supplementation, 100 breeder hens (Hubbard JA 57 K) and ten cockerels were allocated to ten housing groups, with each receiving supplementation of either 4.0 […]
