We should not manipulate the genome of domestic hogs.

Abstract

We can approach the ethical question of whether we ought to use genetic engineering to change domestic hogs from two directions: first, treating the hogs as nothing but means to human ends and, second, considering the well-being of the hogs to be morally relevant. In both of these approaches we can employ a common-sense conception of ethics, that a major goal of morality is to minimize suffering and otherwise make life in this world happier and more fulfilling.
