An analysis of the ethical impacts of the use of anAutomatic Milking System (AMS) is employed as a casestudy to illustrate the use of a form of bioethicalanalysis in technology assessment. The approach isbased on the Ethical Matrix, where `impacts' areassessed in terms of (lack of) respect for threeethical principles as applied to interest groups. Inthis case, only impacts on dairy cows are examined,and principally in terms of their behaviouralfreedom.In contrast to traditional milking systems, AMS, inprinciple, allow cows to present (...) for milkingvoluntarily. So with AMS, it is claimed that dairymanagement relies on the autonomous interaction of thecow with her environment. (shrink)

Responsibility as a dual to human rights is presented as a moral alternative to extended, complex systems of animal and ecological rights. This simple idea of responsibility is then applied to four levels of agricultural technology: animal (nature) rights, conservation, organization of agriculture, and people versus planet relationships. The stewardship argument is freed from at least some of the complications of animal rights and ecology, but leaves responsibility with humans to do the right thing.

In assessing the welfare of dairy cows and laying hens, longevity has recently been introduced as an indicator. This paper presents recent attempts to transfer the normative power of longevity to non-human animals and evaluates this choice systematically. It first shows that the normative power of longevity can be justified by utilitarianism but not by rights-based approaches. The case of the ban to kill day-old chicks in Germany is then used to show that public opinion leans neither to the utilitarian (...) approach nor to the rights-based one but draws a firm line between killing animals before and after reaching an adult age. This may be not so much a desire for longevity among farmed animals but a first sign of empathy that may transform our relationship with farmed animals. (shrink)
