[Biotechnology: hail to man and animal].
There are two basic remarks that must be made about this series of articles on the theme 'Modern biotechnology: a blessing or concern?'. Firstly, it is difficult to define what 'biotechnology' is due to the diversity of techniques employed. Secondly, it is striking how biotechnological techniques may be employed for such a wide variety of goals. In this article, the ethics of using biotechnology within veterinary science and research will be discussed. Aside from its usefulness to humankind, an animal has its own value as a living creature; a fact that we should always take into account. Ethical issues such as the health, welfare and integrity of animals are discussed here in relation to developments in biotechnology. These ethical arguments reveal that biotechnology does not always have a positive impact on animals. This does not necessarily mean that biotechnology should be rejected out of hand, but that it is essential that the purpose for which the animals are being used be adequately justified. In this regard, the veterinarian may play a unique role as the guardian of both animal and human health. The veterinary profession, in all its diversity, is a participant in the development and (future) practical application of biotechnological techniques. Changes in the broader society and within the veterinary profession may continue to play a role in the societal discourse on biotechnology and its practical application, it must actively consider the ethical aspects and consequences of these scientific developments.
