A Scenario Analysis for Implementing Immunocastration as a Single Solution for Piglet Castration.

Painful castration of male piglets to avoid boar taint can potentially be replaced by three more ethical alternatives: entire male production in combination with a detection method, immunocastration (an active vaccination against the gonadotrophin-releasing factor, GnRF), and castration with pain relief (anesthesia and/or analgesia). With the aim of abandoning piglet castration and facilitating internal trade, the European Union (EU) was initially in favor of a single alternative. Immunocastration was proposed as a potential solution, but it has not yet been sufficiently assessed regarding its market potential. To address this point, this paper uses scenario analysis to examine whether and under what conditions immunocastration could be the general solution sought by the EU. The study constructs two extreme scenarios: one in which all uncertain elements negatively influence the growth of immunocastration; another in which all uncertain elements have positive influences. These scenarios provide insights into the variance in possible futures for the implementation of immunocastration. The results show that it is unlikely that immunocastration will become a single solution for all producers in the EU, because it is not the optimal solution for all types of EU pork production systems (i.e., cost-efficiency oriented, quality oriented, animal-friendly oriented, import dependent). Rather than debating and looking for evidence about which single method is the best for the entire EU, EU authorities are advised to allow the co-existence of all alternatives and to develop protocols for applying them in the pork industry.

Paradoxical consumers in four European countries: Meat-eating justification and willingness to pay for meat from animals treated by alternatives to surgical castration.

To prevent boar taint, male piglets are commonly castrated without pain relief, causing them tremendous pain. There are, however, three alternatives, all of which have pros and cons: (1) surgical castration (SC) with pain relief, which removes boar taint but involves extra work for farmers and veterinarians; (2) raising non-castrated or entire male pigs (EM) in combination with a boar-taint detection method; and (3) immuno-castration (IC) by vaccination, which can lower the risk of boar taint acquired from GnRH pulses, but there are concerns about consumer response. The successful marketing of products from animals treated by alternatives to conventional castration depends on consumer acceptance. The current study (involving 3574 participants from Belgium, France, Spain, and Poland) aims to determine whether consumers' willingness to pay for meat from animals treated by alternatives depends on their attitude towards pork, attitude towards local ways of farming, and knowledge of animal welfare. We interpret these in the context of a meat-related moral dilemma and further investigate whether consumers resolve the moral dilemma by applying meat-eating-justification (i.e., apologetic or unapologetic) strategies. The results show that participants are least willing to pay for pork from castrates without pain relief. Willingness to pay for IC pork scores highest, followed by EM. Some consumer groups used an apologetic strategy to reduce the dissonance between moral dilemma and willingness to pay for meat from SC castrates. For the European market, it appears therefore feasible to market pork produced using IC or EM methods.

Consumers' view on pork: Consumption motives and production preferences in ten European Union and four non-European Union countries.

To analyse consumers' attitudes and perceptions towards pork, online surveys were performed with 11,294 consumers from ten European Union (EU) and four non-EU countries. The survey indicates that, although animal welfare affects consumers' view on pork, it is not consumers' primary concern. For most countries, the ranking order of food motives was health and natural, sensory quality, price, and animal welfare. The ranking order for pork production preferences was quality and health, environmental and animal friendliness, regional identity, and production efficiency. A choice experiment, conducted for four countries: Denmark, France, Italy, and Poland, showed that natural was the most important factor, followed by health, taste, animals' pain and stress, costs, and pharmaceutical interventions. Four consumer segments were identified: Demanding, Average, Low-on-eco, and Indifferent. Although the percentage shares of these groups differ in each country, we conclude that consumer consumption motives and production preferences are sufficiently similar to include them as communicative elements in marketing strategies for meat from non-castrated pigs.

International Students' Mental Health Care in China: A Systematic Review.

International students in China are facing difficulties while adapting their Chinese culture, and their life is influenced by the widespread of the Coronavirus Disease 2019 (COVID-19), and caring for their mental health is currently challenging. As a result, our aim is to explore the current mental health care of this minority in China and to provide useful suggestions for future research and institutes. We used the systematic review method, and it was conducted on 11 existing pieces of literature. Our results confirm the unsatisfying psychological situation of international students and the lack of research in this area. We focus on the causes and symptoms of mental problems and explore the effectiveness of methods.

Examining Alternatives to Painful Piglet Castration Within the Contexts of Markets and Stakeholders: A Comparison of Four EU Countries.

To avoid the occurrence of boar taint in pork, the castration of piglets without pain relief is a common practice in many European countries. The public has been calling for more animal-friendly alternatives, which include anesthesia/analgesia, immunocastration, and the raising of entire males. To prevent potential trade barriers, the European Commission was initially more in favour of a single method. To date, however, only six countries have passed laws banning castration, and the pig farmers in these countries have chosen different alternatives. To understand the reasons behind the continuing fragmentation, this study examines the issue of castration within the context of four national pork production systems: in the Netherlands, France, Slovenia, and Germany. Drawing on in-depth qualitative data, the study demonstrates that stakeholders are generally willing to abandon the practice of piglet castration without anesthesia/analgesia. Their preferences for alternatives are largely dependent on contextual factors, however, including the structure, scale, and cost and quality orientation of the production system. The results imply that, although a single solution for castration is unlikely to evolve amongst the diverse pork-production systems in Europe, a future without the painful castration of piglets is possible if alternatives are accepted to coexist.
