Nonhuman animal welfare is arguably the most contentious issue facing the hog industry. Animal advocacy groups influence the regulation of hog farms and induce some consumers to demand more humane pork products. Hog producers are understandably reluctant to improve animal well being unless the premium they extract exceeds the corresponding increase in cost. To better understand the relationship between animal welfare and production costs under different farm systems, this study investigates 4 stylized hog production systems. The results show that increasing animal welfare for all hogs in the United States will increase retail pork prices by a maximum of 2% for a small welfare increase and 5% for a large welfare increase. The cost of banning gestation crates measured by this study is lower than the consumer willingness-to-pay from other studies.
非人类动物福利可以说是养猪业面临的最具争议性的问题。动物权益倡导组织影响着养猪场的监管,并促使一些消费者要求更多人道的猪肉产品。可以理解的是,养猪生产者不愿改善动物福利,除非他们获得的溢价超过相应增加的成本。为了更好地理解不同养殖系统下动物福利与生产成本之间的关系,本研究调查了4种典型的养猪生产系统。结果表明,在美国,对所有生猪提高动物福利,小幅提高福利时零售猪肉价格最多上涨2%,大幅提高福利时最多上涨5%。本研究测算的禁止使用限位栏的成本低于其他研究中消费者的支付意愿。
