Egg production, egg and bone quality, and health of young laying hens under UV supplementation

These data were collected from laying hens during the early laying phase to determine the effects of UVA and UVAB light supplementation indoors relative to control lighting (no UV spectrum) on egg production/quality, plasma Ca, P, 25(OH)D3 , bone Ca and P and breaking strength. \nLineage: Measurements were made on individual hens within the three treatment groups across different time points of their body weight and external health indicators. Blood samples were taken periodically from a subset of hens to extra serum and plasma for mineral and vitamin assessments. Egg production and egg quality was assessed daily/twice respectively and leg bones were extracted from a subset of hens to assess bone health.
