Birds poultry farming

For use in poultry farms where wild birds are attracted a test with birds is necessary... 

Predation (e.g. by foxes and birds of prey) may also be a serious cause of mortality in free-range husbandry. Foxes can be kept away with a solid fence, which can be supplemented by an electric fence. Birds of prey are not a big problem for poultry houses that are closed at night and free of holes. However, keeping birds of prey such as the hawks away is not easy, especially for farms surrounded by forest or in a landscape with a lot of trees. In such situations, low structures should be provided as hiding places for the hens. 

Avian influenza H5N1 is an infectious disease of birds. It can cause two distinct forms of disease one is mild while the other is deadly. The virus is thought to be spread by migratory birds. Animals, especially farm poultry/animals, that lie under the migratory paths of the birds can become infected. To date, culling is the most effective means of controlling the spread of avian influenza in domestic poultry/animals. 

The addition of carotenoids to the diet of different animals is commonly used as a method to incorporate certain carotenoids into products that wUl be obtained from such animals. For instance, (3-carotene is added to cattle foodstuff to increase the concentration of provitamin A in milk. In poultry, alfalfa and maize respectively are used as lutein- and zeaxanthin-rich sources, pigments that are incorporated for the pigmentation of the skin and, in particular, egg yolk. The red and yellow coloring of the feathers of certain birds is due to the presence of dietary carotenoids. In the case of salmon, the red color of the flesh is due to pigmentation with dietary astaxanthin and canthaxanthin, which can be introduced artificially in animals bred on fish farms.
