Zinc promotes feather recovery of birds
The addition of zinc to the drinking water promotes
the recovery of the feather pack of poultry.
In addition, the supplementation of fresh straw seems to cure skin
infections in the birds. These are the findings of research done by Dutch Health Institute for Animals
Dutch free range, cage and Freiland birds are contending with mysterious
skin problems since 2004. The birds lose their feathers and have round damages
on belly and cloaca. The mortality of these problems can reach 1% or more per
week. No correlation was noted between type of birds, feed producer or type of
Dutch poultry producers try to minimise the mortality by adding acids to
the drinking water or feed. Furthermore, the farmers supplement the animals with
extra vitamins, biotin, selenium and zinc. The Dutch GD found out that the
supplementation of Federfein
, a zinc product, has the best results in reducing
the skin infections. An elevated zinc supply does not lead to a higher zinc
concentration in the liver, but increases the zinc level in the manure.
