Consumer beliefs	Animal welfare worries me		Aluwé et al. (2020), Cabana (2010)
	I know that sometimes male pigs intended for consumption are castrated without anaesthesia at birth
	I think castration of pigs without anaesthesia should not be done	Scale of 1–9 points
	The castration of pigs is justified because it improves the smell and flavour of the meat

	A high fat content in a meat product is negative for me
