[The use of biotechnology in animal breeding].

Biotechnological techniques are extensively used in dairy breeding programs. Thus, artificial insemination and embryo transfer (and associated techniques) constitute an integral part of modern breeding programs. In pig breeding, embryo transfer is mostly restricted to special problem areas because of its high costs. Currently this technique is used for the exchange of genetic material on an international level, for the creation of specific pathogene free herds, and in connection with cryoconservation for the setup of embryobanks in the context of the preservation of genetic resources.
