Wild carrot (Daucus carota
) contains a valuable source of carotenoids, which have been used for years as an addition to poultry diets for their ability to provide a rich color to the egg yolk and skin. Different colors of carrots contain different types of carotenoids.
Supplementing the feed of egg-laying hens with colored carrots efficiently increased yolk color parameters and carotenoid contents, which gives opportunities for improved nutritional value of eggs from forage material-supplemented hens.
Feather pecking reduction
Providing chickens with access to maize silage, barley-pea silage and carrots as foraging materials decreased damaging feather pecking
in general (to feathers as well as skin/cloaca), reduced severe feather pecking behavior and improved the quality of the plumage at 54 weeks of age.
