In order to achieve the latter more efficiently, as well as to assist in conventional breeding efforts, the entire genomes of animals are being characterised and sequenced using biotechnology tools.These activities have been arbitrarily grouped under animal biotechnology since they either utilize animal cells to generate products or apply biotechnological tools to enhance the usefulness of animals to human welfare.
The products from animal cell cultures are primarily used for human health care, and many of them are related to the immune system. Therefore, we shall consider the immune system in some detail before we consider the various other aspects of animal biotechnology.
