This paper analyses the use of the cultural convention of suzhi in attempts to improve biosecurity practices in the Chinese pig industry. Suzhi loosely refers to 'quality' and has been used to define the appropriate conduct of citizens during the era of market reforms. Like other forms of agricultural governmentality, suzhi provides a way of distinguishing 'good farming' and creating entrepreneurial subjectivities. However, in other policy areas, suzhi has been shown to marginalise the poor and reinforce social inequalities. This paper examines the extent to which discourses of suzhi in a biosecurity context contributes to the use of preventive animal health practices, amongst pig farmers in Chongming Island, Shanghai. Drawing on documentary evidence and interviews with 33 farm animal breeders and 3 pig veterinary surgeons, the paper examines how suzhi contributes to the creation of 'good farming' subjectivities in order to modernise the animal health practices of pig farmers. The paper shows how suzhi contributes to the valourisation and stigmatization of different pig farming subjectivities, suggesting that it reinforces existing socio-economic inequalities. Moreover, the paper describes the ways in which modes of conduct associated with suzhi are negotiated and challenged and reduced to a symbolic 'cloak' that disguises the reality of preventive animal health practices.1 It is one of the primary objectives of the 11 th Five-Year (2006-10) policy program to develop the Chinese countryside with advanced production, a comfortable livelihood, a civilised lifestyle, clean and tidy villages and democratic administration. This program aims at combining agricultural modernisation, rural governance innovation, the expansion of social welfare, the strengthening of rural education and fiscal reform (See also in Schubert and Ahlers, 2012, p70). 2 This is a policy to improve rural people livelihoods and transform Chinese villages into well-off and civilised places. 3 The discourse of 'Building of Beautiful China' is emphasised by the 18 th National Congress of the Central Planning Commission. It is defined as "the sum of the beauty of the environment, the beauty of the times, the beauty of life, the beauty of society and the beauty of common people" (See Marlinelli, 2018, p14).
