Vitamin D deficiency is a global health problem. This study aimed to investigate the efficacy of ultraviolet (UV) B radiation for improving vitamin D 3  content of eggs and meat. In a two-factorial design hens that received diets with 0 (-D 3 ) or 3,000 IU (+D 3 ) vitamin D 3 /kg were non-exposed (-UVB) or exposed to UVB radiation (+UVB) for 3 h daily over 4 weeks. Data show that UVB radiation was very effective in raising the vitamin D 3  content of egg yolk and meat. Egg yolk from +UVB/−D 3  hens had a higher vitamin D 3  content (17.5±7.2 µg/100 g dry matter (DM)) than those from the –UVB/+D 3  group (5.2±2.4 µg/100 g DM,  p <0.01). Vitamin D 3  content in egg yolk of vitamin D 3 -supplemented hens could be further increased by UVB radiation (32.4±10.9 µg/100 g DM). The content of 25-hydroxyvitamin D 3  (25(OH)D 3 ) in the egg yolk also increased in response to UVB, although less pronounced than vitamin D 3 . Meat revealed about 4-fold higher vitamin D 3  contents in response to UVB than to dietary vitamin D 3  ( p <0.001). In conclusion, exposure of hens to UVB is an efficient approach to provide consumers with vitamin D 3 -enriched foods from animal sources.
