Ethical attitudes in relation to meat purchases were studied among urban and rural consumers in Scotland. All subjects perceived at least some ethical issues in relation to animal production systems, in particular, systems keeping animals in close confinement. Welfare‐friendly production systems were viewed as adding value to a food, but this value was not necessarily realizable to producers if purchases occurred only when foods were on special offer. Statements made by individuals were often contradictory, revealing ambivalence, unresolved value conflicts and a general lack of involvement in the nature of meat production. A number of barriers to the establishment of stable attitudes and behaviours in relation to the ethical treatment of food animals were also identified. A key finding of the study is that individuals can hold two views on animal welfare. On the one hand, they may think as citizens influencing societal standards, and on the other, as consumers at the point of purchase. As citizens, they support the notion of animals being entitled to a good life; as meat consumers, they avoid the cognitive connection with the live animal. This paper explores both the citizen–consumer relationship and purchase strategies used by consumers to resolve value conflicts. Lessons for public and commercial policy are highlighted in the context of the Curry Report (2002) which advocates more effective market segmentation where markets are finely attuned to their customers, with the development of a number of assurance schemes discussed in the article.  相似文献

While the recent surge of meat-like items on restaurant menus has received considerable attention, little is known how to encourage consumers to choose such novel dishes. To address this gap, we investigate the role of various communication strategies in making plant-based menu items more attractive. The results from Study 1 suggest that using a social appeal in the ad increases consumers’ preference for plant-based menu items via anticipated pleasure, but a health appeal does not. The results from Study 2 demonstrate that information on social costs induces feelings of ambivalence toward meat eating, thus making plant-based menu items more desirable. However, information on health risks of meat consumption does not have such an effect. Practical implications for promoting plant-based menu items are discussed.  相似文献

目前,消费者对肉类食品安全状况表示担忧,消费者对兽药残留、饲料添加剂、食品添加剂的不舍理使用,以及病畜肉问题关注程度较高。对风险程度较高的微生物污染关注程度较低。在购买肉类食品过程中。颜色、气昧等易于直接识别的特征是消费者用于判断肉类食品质量常用的质量信号,对价格、食品标簦所提供的质量信息的信任程度不高。政府应加强食品安全信息披露体系建设,为肉类食品生产者的安全生产行为提供激励。  相似文献

The remarkable economic changes occurring within China since 1978 have resulted in a striking alteration in food consumption patterns, and one marked change is the increasing consumption of meat. Given China’s large population, a small percentage change in per capita meat consumption could lead to a dramatic impact on the production and trade of agricultural products. Such changes have major implications for policy makers and food marketers. This paper concentrates on meat consumption patterns in the home in China. A censored linear approximate almost ideal demand system model was employed in the study, and major economic parameters were estimated for different meat items. Data used in this study were collected from two separate consumer surveys – one urban and one rural in 2005.  相似文献

Several consumer studies have shown considerable market potential for sustainable meat products, however, their markets shares are still marginal. In Germany, the sustainable aspects “organic,” “local origin,” and “animal welfare” are of special interest. To obtain a precise overview of potential target groups for these meat categories and their choice of store format, 620 German consumers were surveyed on their attitudes toward sustainable meat production and their shopping behavior. First, target groups based on consumers’ attitudes were identified by cluster analysis, taking into account possible overlaps. Consumers were also clustered by their store format choice and their preferred type of meat packaging. A cross tabulation of the results then provided insights into which store format and type of meat packaging is preferred by the target groups for sustainable meat products. Due to overlaps found in the target groups, the existence of important subgroups was shown. Amongst the target groups, only a slight preference for unpackaged meat products was found. Basically, the offer of sustainable meat products appears of interest for all store formats, with particular emphasis on supermarkets. The results of this study can support producers and retailers developing new and tailored marketing strategies for sustainable meat products.  相似文献

This study analyzes Canadian consumer willingness to pay for omega-3 enhanced beef, pork, and chicken. Using a nationwide survey conducted by ACNielsen in 2006 and choice modeling framework, results indicate that smaller household, households with high incomes, and households that have previously purchased an omega-3 product are willing to pay a premium for omega-3 beef, pork and chicken. The results also suggest that consumers that have previously purchased an omega-3 product are willing to pay a higher premium for the respective omega-3 meats compared to households that have never purchased an omega-3 product. Also, premiums are highest for omega-3 beef, followed by omega-3 pork, and last, omega-3 chicken.  相似文献

This paper simulates pig producer and slaughterhouse income losses due to a classical swine fever outbreak in Finland. The analysis explicitly takes into account that an outbreak of a highly contagious animal disease can shrink export demand for pig meat. After having observed the disease and its impact on pig meat price, producers can optimize animal stocks thought insemination decisions, which affects the number of animals in a dynamic manner. The income losses of pig industry were estimated to be less than €30 million. The losses were mainly due to price movements caused by an export demand shock. The results suggest that if the outbreak causes distortions in meat trade, the disease can cause substantial losses to the industry even if it has directly a small impact on the number of animals on farms. We also found that the optimization could reduce disease losses significantly, even more than 50%.  相似文献

Growing demand for agricultural produce, coupled with ambitious targets for greenhouse gas emissions reduction present the scientific, policy and agricultural sectors with a substantial mitigation challenge. Identification and implementation of suitable mitigation measures is driven by both the measures’ effectiveness and cost of implementation. Marginal abatement cost curves (MACCs) provide a simple graphical representation of the abatement potential and cost-effectiveness of mitigation measures to aid policy decision-making. Accounting for heterogeneity in farm conditions and subsequent abatement potentials in mitigation policy is problematic, and may be aided by the development of tailored MACCs. Robust MACC development is currently lacking for mitigation measures appropriate to sheep systems. This study constructed farm-specific MACCs for a lowland, upland and hill sheep farm in the UK. The stand-alone mitigation potential of six measures was modelled, against real farm baselines, according to assumed impacts on emissions and productivity. The MACCs revealed the potential for negative cost emissions’ abatement in the sheep industry. Improving ewe nutrition to increase lamb survival offered considerable abatement potential at a negative cost to the farmers across all farms while, lambing as yearlings offered negative cost abatement potential on lowland and upland farms. The results broadly advocate maximising lamb output from existing inputs on all farm categories, and highlight the importance of productivity and efficiency as influential drivers of emissions abatement in the sector. The abatement potentials and marginal costs of other measures (e.g. reducing mineral fertiliser use and selecting pasture plants bred to minimise dietary nitrogen losses) varied between farms, and this heterogeneity was more frequently attributable to differences in individual farm management than land classification. This has important implications for the high level policy sector as no two farms are likely to benefit from a generic one size fits all approach to mitigation. The construction of further case-study farm MACCs under varying farm conditions is required to define the biophysical and management conditions that each measure is most suited to, generating a more tailored set of sector-specific mitigation parameters.  相似文献
