Animal welfare is an increasingly important factor in the purchasing decisions of consumers (Napolitano et al., 2010), sustained despite the prevailing recession (IGD, 2011). Recent surveys indicated almost half of UK consumers surveyed rated animal welfare as either ‘very important’ or ‘extremely important’ (IGD, 2011), whilst 76% (Defra, 2011) and 85% (Clonan et al., 2010) rated welfare as ‘an important’ issue. In fact, farm animal welfare was rated the single most important sustainability related food issue for British consumers (IGD, 2011; Defra, 2011), above health or safety concerns. Over 70% of U.S citizens surveyed also reported ‘concern’ forfarm animal welfare (Norwood and Lusk, 2011a). Pigs were identified amongst the three animal systems most in need of animal welfare improvements by EU citizens (European Commission, 2005).
