Název v původním jazyce

The substitution of synthetic sources of carotenoids in mixed feed for hens

Popis výsledku v původním jazyce

ISA Brown hens were fed diets supplemented with the synthetic carotenoids Carophyll Red and Carophyll Yellow at 20 and 15 mg/kg, respectively; lutein at 250 mg/kg; and the algae Chlorella at 12.5 g/kg. The synthetic carotenoids, lutein and Chlorella significantly increased egg weight and shell weight and thickness and decreased the yolk/albumen ratio of the eggs. Lutein but not the Carophylls or Chlorella significantly increased the shell breaking strength. Furthermore, the carotenoids and Chlorella significantly increased yolk color, and the yolk redness increased significantly in the following order: control, Chlorella, Carophyll and lutein. Lutein and Chlorella increased the yellowness of the yolks. Supplementation of feed with lutein and Chlorellasignificantly increased the concentration of lutein and zeaxanthin in the yolks.
