Canadian consumer valuation of farm animal welfare and quality verification the case of pork

Uzea, Adrian Daniel 07 July 2009
There is increasing pressure from animal rights organizations (AROs) on restaurant chains, food retailers, and meat processors to implement more stringent farm animal welfare (FAW) requirements for their suppliers. In the United States, AROs have recently initiated successful ballots to phase out confinement practices in several states. In Canada AROs have been pressuring both public and private sector stakeholders to improve FAW. Are FAW issues, however, paramount in the minds of Canadian consumers? Is the demand for more stringent FAW protocols primarily determined by a subset of consumers with very strong preferences or does it signal a more fundamental underlying change in consumer and societal preferences? Given the credence nature of FAW, who do consumers trust (i.e., government vs. private industry vs. independent third parties) in the market place for the provision of FAW quality assurances? What are the determinants of trust in these organizations for providing accurate information about animal welfare?<p> In order to answer these questions, a stated preference consumer survey encompassing FAW issues specific to the Canadian pork sector was tested on two samples of consumers in summer 2008, namely: a general population sample (GPS) across Canada and a sample of AROs members. Consumers participated in a purchase experiment where they had to chose between pork chops characterized by combinations of different levels of FAW attributes (i.e., housing system, gestation stalls, and use of antibiotics), quality verifying organization, and price. Multinomial Logit and Latent Class Logit Models were used to analyse the survey data.<p> Surprisingly, outdoor system does not seem to resonate well with Canadians, as both the GPS and the members of the AROs discounted this attribute. As expected, the AROs members have much stronger preferences for the other FAW attributes than have consumers in the GPS. Nevertheless, significant heterogeneity exists within consumer preferences. Five classes of consumers were identified in the GPS with respect to their preferences for FAW. At one end of the spectrum are the FAW sensitive consumers (12.3%) that have higher willingness-to-pay (WTP) for FAW, while at the other end of the spectrum Price Conscious consumers (18.3%) do not exhibit any WTP for FAW. The other three classes (69.4%) comprise respondents with mixed perceptions regarding FAW. Government and Third Party verification of FAW quality assurances had the strongest influence on consumers preferences in both samples. As well, scientific experts in FAW along with the above two organizations are the most credible in providing information about the welfare of pigs. The extent to which these organizations are knowledgeable about the welfare of pigs is the most important factor enhancing consumers trust. Results from this study suggest that there are potential marketing opportunities for pork chops sourced from pigs raised on farms where sows are kept in groups, and where credible quality assurances can be established, that private industry could consider. As well, the results suggest that consumers would derive benefits from the government taking a more active role with respect to validating FAW quality assurances.

Question socialement vive et développement du pouvoir d'action des enseignants et des élèves : la question du bien-être animal en élevage dans les lycées professionnels agricoles / Socially acute question and development of teachers’ and students’ power to act : the question of farm animal welfare in agricultural schools

Lipp, Amélie 07 November 2016 (has links)
La prise en compte du bien-être des animaux dans les élevages suscite de vives controverses dans la société et dans les champs scientifique, technique et professionnel. Dans le milieu scolaire, le bien-être animal (BEA), en tant que question socialement vive (Legardez & Simonneaux, 2006), pose des difficultés pour son enseignement et son apprentissage dans les lycées professionnels agricoles préparant les futurs éleveurs. Cette thèse a pour objet de comprendre comment le pouvoir d’action (Clot, 1999) des enseignants et des élèves relatif à la prise en compte du BEA en situations d’enseignement-apprentissage se développe (ou ne se développe pas). Nous articulons les cadres théoriques et méthodologiques de la didactique des questions socialement vives, de la clinique de l’activité et du jugement éthique. Dans une double visée transformative et épistémique, quatre enseignants de zootechnie et leur classe de baccalauréat professionnel ont participé à un protocole d’intervention en lycées. A partir des traces des activités dialogiques recueillies, nous avons documenté les émotions, les jugements éthiques et les représentations-connaissances signifiés ainsi que leurs interactions et les conflits à l’œuvre dans le développement possible et impossible du pouvoir d’action des sujets relatif à la prise en compte du BEA en élevage. L’ensemble des résultats permet de mettre à jour des obstacles et des leviers au développement du pouvoir d’action des élèves et des enseignants. Nous formulons plusieurs propositions pour la formation des enseignants et des élèves afin de les accompagner à affronter certains obstacles et à davantage valoriser les leviers potentiels pour augmenter leur champ des possibles. / The question of farm animal welfare has sparked strong debate in society and in scientific, technical and professional domains. In the field of education, teaching and learning about farm animal welfare (FAW) as a socially acute question (Legardez & Simonneaux, 2006), is particularly problematic in agricultural schools which train future breeders. The aim of this thesis is to understand how the power to act (Clot, 1999), in relation to the question of FAW, develops (or not) in both teachers and students during teaching-learning situations. We articulate the theoretical and methodological frameworks of the didactics of socially acute questions, the clinic of activity and ethical judgment. Four animal husbandry teachers participated in a protocol with their vocational baccalaureate students. Based on their dialogical activities, we recorded their emotions, ethical judgments and knowledge-representations systems along with their interactions and the conflicts at work to help or hinder the development of their power to act.Our results reveal the barriers and the facilitators to the development of the students’ and teachers’ power to act to improve FAW. We make several recommendations for the training of teachers and students which should help them to overcome certain hurdles and further exploit the potential levers allowing them to widen their range of possibilities.
