NEKTON-GELB 35 grams (1.23 oz) Prevent colours from fading or heighten yellow shades of plumage by adding NEKTON-GELB. The nature-identical carotenoid Apo-8-carotenoic acid ethyl ester gives the yellow shades a strong and brilliant hue. Add to nestling or egg food, or to drinking water, at the beginning of the moult until a full set of new feathers has grown in. In order to help a bird through this time of pressure and strain and maintain health, which also reflects in full and shiny feathers, the carotenoid has been added to a basic formula of important vitamins, essential free amino acids and a combination of macro and trace elements.
