A pig research biography is an analytical focus that foregrounds connections between the various kinds of labour involved in establishing pigs as models of human patients. By paying attention to the variety of practices that pigs undergo across sites and by examining connections between their effects, pig research biographies provide a means to argue for the mutual requirement of seemingly incoherent kinds of labour and ways of knowing pigs. The aim of writing pig's research biographies is to show how human and pig lives are inseparable, but also to bring forward how different values become attached to pig and human in experimental biomedical research. This chapter looks at the kind of domestication practices that unfold at the stables and their consequences for pig's research biographies. The aim of writing pigs research biographies is to foreground the continuity between the seemingly incoherent kinds of knowledge practices that relate to names and numbers.
