Working group Nutrition of Poultry

The till now known 10350 species of bird settle all biotope of the earth. Your feathers which both protect the body from temperature fluctuations and offer the animals the possibility of moving flying free about large distances have led to a spreading up to the most remote areas of our earth. Every biotope is used as long as the birds can find feed. The feed spectrum contains fish, meat, insects, spiders, fruits, berries, grasses, seeds, leaves and flower nectar. The smallest bird on the earth is the bumble-bee Hummingbird with a weight of only 2 g. On the other hand, the Mute swan with up to 22 kg of weight, the European great bustard (18 kg) and the Dalmatian pelican (13 kg) are part of the heaviest able to fly birds. The African ostrich as greatest bird (body height to 2.7 m, weight over 150 kg) is a flightless bird. Despite the large number of birds only species have attained economic meaning from the order of the chicken birds, goose birds and pigeon as well as on a smaller scale the big run birds ostrich, emu and rhea.

The scientific trials at the Institute of Animal Nutrition are carried out at the economically most important birds - laying hens, chickens, turkey and ducks for fattening, as well as into low size to quail and spring chickens. In our studies questions on feeding are examined particularly to reach one optimal performance (growth - meat, eggs) in an economic frame (e.g. favourable feed efficiency) and at saving of the environmental resources. These aims can be carried out only with vital birds whose development is already managed in the hatchery with temperature stimulations. Studies for the question of the effectiveness of use of individual feedstuffs or additives of all sorts of category (herbs, essential oils, amino acids, trace elements, vitamins), serve the aim of finding out the optimum of a supplementation for the birds in his performance phase. Some results are exemplary in the following represented from the variety of the studies of the working group "Poultry".

Scientific examinations were carried out mainly to laying hens, chickens, turkey and ducks for fattening, quails, spring chickens:
