The increase in meat consumption expected in the next decade will require more and more proteins for animal feeding. The recent amendments to the European "BSE Regulation" allow the use of insects and porcine-based meals in poultry farming, providing novel, sustainable substitutes for vegetable fodder. While the technological and nutritional properties of novel feeds containing processed animal proteins are widely recognized, far less is known about consumers' acceptance of meat produced by animals fed on animal-based meals. In the present research, a best-worst survey was applied to estimate consumers' preferences for chicken fed on plants, insects, or porcine-based meals using a sample of 205 Italian consumers. Furthermore, product price, type of farming, and "Free-from" labeling were considered in the analysis to evaluate the relative importance of feed ingredients compared to other important attributes of meats. The results show that the most relevant attributes are type of farming and "Free-from" claims, while type of feed represents the third attribute in order of importance. Notably, both insect and porcine flour are considered as negative characteristics of the product, suggesting that mandatory labeling signaling the use of these feeds would negatively impact on the value of chicken meat.
未来十年，肉类消费预计将会增长，这将需要更多的动物饲料蛋白质。欧洲“疯牛病条例”的最新修正案允许在禽类养殖中使用昆虫和猪源性饲料，为蔬菜饲料提供了新颖、可持续的替代品。虽然含有加工动物蛋白的新型饲料的技术和营养特性已得到广泛认可，但对于消费者对以动物源性饲料喂养的动物生产的肉类的接受程度，人们知之甚少。在本研究中，我们采用最佳最差法调查，利用意大利 205 名消费者的样本，评估消费者对以植物、昆虫或猪源性饲料喂养的鸡肉的偏好。此外，在分析中还考虑了产品价格、养殖类型和“无添加”标签，以评估饲料成分相对于肉类其他重要属性的相对重要性。结果表明，最相关的属性是养殖类型和“无添加”声明，而饲料类型则是按重要性排列的第三属性。值得注意的是，昆虫和猪粉都被认为是产品的负面特征，这表明强制标签表明使用这些饲料将对鸡肉的价值产生负面影响。
