Welfare assessment of cattle submitted to equestrian sporting events

The concern with the animal’s welfare has become increasingly frequent and the use of cattle in sporting events has aroused discussions about the preservation and integrity of these animals. The objective of this work was to evaluate whether the cattle participating in the team roping modality receive all support regarding the animal welfare criteria. During the 41st National Championship of the Quarter Horse Breed of Work and Conformation, aspects of animal welfare of 410 cattle that participated in the team roping were evaluated. Behavioral aspects were observed before, during and after the end of the competition, in addition to quantifying the number of runs per animal, the presence of ectoparasites, thermal comfort, food and hydration. It was possible to conclude that the environment in which the tests were carried out, the feeding conditions, the space and the thermal comfort meet the criteria of animal welfare.

Is Animal Welfare an Internationally Understood Concept in the Zoo World? Thematic Analysis of Two Regional Groups of Zoo Staff.

Simple SummaryIn order to ensure we do not speak at cross-purposes, common understandings and definitions are useful. However, there is no universal definition of animal welfare. Structured interviews with a sample of European and Chinese zoo staff aimed to explore their perceptions and understanding of the term ‘animal welfare’, and the use of animal welfare frameworks in a zoological context. Thematic analysis demonstrated that all interviewees used similar descriptors when discussing animal welfare including describing animal feelings and emotions. Animal welfare frameworks were considered useful across both regions. However, different frameworks were suggested by interviewees in Europe to those in China. Chinese zoo staff expressed the importance of leadership in animal welfare in Chinese zoos. These findings suggest a common understanding of the concept of animal welfare, and the usefulness of animal welfare frameworks across geographically and culturally diverse regions.Universal frameworks for zoo animal welfare have been suggested. However, there is little evidence of a cross-cultural understanding of zoo animal welfare. This paper reports themes emerging from a qualitative study of international (European and Chinese) zoo professionals on zoo animal welfare issues. Structured telephone interviews were conducted with eight Chinese and eight European zoo staff, covering aspects of zoological animal welfare, conservation and zoological husbandry practices. These qualitative data were thematically analysed, and key themes generated. This paper describes three themes relating to ‘What is animal welfare’ ‘Animal welfare frameworks’ and ‘The human element in animal welfare’. This analysis indicates that the concept of animal welfare has cultural equivalence across Europe and between Europe and China, and that zoo staff are familiar with welfare frameworks. In China, a need for senior leadership and motivating staff to improve animal welfare emerged.

The effects of farming systems (organic vs. conventional) on dairy cow welfare, based on the Welfare Quality® protocol

Animal welfare in livestock production is of great interest to consumers. The organic farming approach strives to ensure animal welfare based on preventive measures, but there are very few scientific studies that compare the actual differences in animal welfare between organic and conventional farms. Those studies that have been carried out frequently focus on specific aspects of animal welfare, mostly health issues. The aim of the present study, therefore, was to investigate the effects of the farming system on the welfare of dairy cows in a more holistic way. Although this study was carried out in just two federal states of Germany, the results could serve as a suitable model for the whole country. We used the Welfare Quality assessment protocol to measure welfare for dairy cattle (Welfare Quality®, 2009) and the results showed significant differences (P < 0.05) between organic and conventional farms, but there was also considerable variance between individual farms of the same farming system. Organic farms scored higher in all four Welfare Quality® principles: “Good Feeding”, “Good Housing”, “Good Health” and “Appropriate Behavior” compared to conventional farms. In particular, organic farms obtained higher scores with respect to Welfare Quality® measures of resting comfort, which contributes to a lower percentage of lameness; organic farms also implemented less painful methods for disbudding, or indeed carried out no disbudding, and provided access to pasture and outdoor exercise. However, organic farms still have room for improvement, especially with respect to animal health. Therefore, outcome‐based specifications should be included in the current (purely action-oriented) European regulation of organic production (EC, 2008; EU, 2018) to safeguard the health‐related aspects of animal welfare.

Digital Phenotyping in Livestock Farming.

Simple SummaryWearable technology has launched human medicine toward new successes, but are these versatile devices really being leveraged to their best capacity? Applying wearable sensors to animal farming contexts represents tremendous potential for cost-conscious growers and welfare-minded consumers alike. Each farm animal’s phenotype—the set, observable variables that an organism displays based on interactions with their environment—offers unique information on health, welfare, and profitability. Previously, these important observations had to be conducted with extensive time, cost, and labor resources—and even then, the results were impossible to standardize or obtain continuously. Thanks to their proven benefits across many human-based studies, digital phenotype readers can collect and relay specific metrics, such as body temperature, cardiovascular functioning, activity level, and even more complex behaviors such as sociability. Due to cross-species variations, these sensors need to be tailored efficiently and accurately. Future research should inform the design of digital phenotyping options that will offer farmers reliable, robust information, with the long-term goal of creating shared data standards and stores.Currently, large volumes of data are being collected on farms using multimodal sensor technologies. These sensors measure the activity, housing conditions, feed intake, and health of farm animals. With traditional methods, the data from farm animals and their environment can be collected intermittently. However, with the advancement of wearable and non-invasive sensing tools, these measurements can be made in real-time for continuous quantitation relating to clinical biomarkers, resilience indicators, and behavioral predictors. The digital phenotyping of humans has drawn enormous attention recently due to its medical significance, but much research is still needed for the digital phenotyping of farm animals. Implications from human studies show great promise for the application of digital phenotyping technology in modern livestock farming, but these technologies must be directly applied to animals to understand their true capacities. Due to species-specific traits, certain technologies required to assess phenotypes need to be tailored efficiently and accurately. Such devices allow for the collection of information that can better inform farmers on aspects of animal welfare and production that need improvement. By explicitly addressing farm animals’ individual physiological and mental (affective states) needs, sensor-based digital phenotyping has the potential to serve as an effective intervention platform. Future research is warranted for the design and development of digital phenotyping technology platforms that create shared data standards, metrics, and repositories.

Local vs. International Hamburger Foodservice in the Consumer’s Mind: An Exploratory Study

Fast-food chains are everywhere and every day millions of people choose to have a break in a fast-food outlet. However, in recent years some local hamburger foodservice chains outside of the well-known international fast-food chains have found success by leveraging products linked with their territory. How do consumers value the service received in an international, rather than a local, fast-food outlet? This aspect is under-investigated in the literature, but is relevant in order to capture the main and most important differences between the two systems. Through a structured survey, consumers’ perceptions of both international and local hamburger foodservice outlets in the Turin Metropolitan area (Italy) were measured and analysed. The results indicate that consumers generally have a break in an international fast-food restaurant, but the value assigned to local fast-food chains is higher than that assigned to international ones. Specifically, local fast-food chains are appreciated for particular aspects related to the supply chain (animal welfare, ethical and social aspects, the origin of the raw materials, and some other characteristics of the food). The findings contribute to a more in-depth understanding of consumer behaviour, and give an insight into the relevance of the local aspects as opposed to the international ones.

‘Kindergarten’ keeping-system in farrowing house: effect the socialization of piglets on weight performances, fecal cortisol metabolite level and post-weaning behavior

This study aimed to examine whether litters’ let-together system before weaning (‘kindergarten-system’) has any stress effect and effect on post-weaning behavior, respectively. One week before weaning piglets were socialized by removing four adjacent farrowing crate walls. After weaning, piglets from the same experimental groups were housed in the same rearing crates. The piglet’s body weight was measured at birth than weekly till the 7th life-week. Fecal cortisol metabolites were measured for evaluation of the adrenocortical activity. Personal observation and evaluation were carried out for behavioral analyses after weaning. There were no significant differences in weight development and cortisol metabolite levels between the control and experimental groups. Behavioral analysis showed that pigs grow up in a socialized system, rapidly evolve ranking in the rearing crates, and the self-maintenance and social behavior were more pronounced. In control groups, the activity involving movement (exploring, walking, and running) was much more decisive. Recent work suggested the beneficial effect of the ‘kindergarten’ system in the farrowing house in animal welfare aspects.

The Contribution Value of Conservation Institution to Animal Welfare Aspects at Serulingmas Wildlife Recreation Park, Banjarnegara

The main functionof conservation institutions is to control breeding and wild plants and rescue wild plants and animals while maintaining the species purity. This role requires conservation institutions to contribute toanimal conservation to save and conserve wild animals ex-situ. This research aims to determine the contribution value of Serulingmas Wildlife Recreation Park as an implementationof animal welfare. The data was collected through interviews and field observations. The results showed that the implementation achievement of animal welfare at Serulingmas Wildlife Recreation Park was classified as good with an achievement value of 76.61.However, the contribution value of Serulingmas Wildlife Recreation Park to the animal conservation aspects was still categorized as low, which was mainly due to the low animal births. Increasing the success of animal births could be carried out through coaching on technical aspects such as improving animal health management and facilities.Keywords: animal welfare, ex-situ conservation, conservation institution, wildlife conservation

Sustainable Meat: Looking through the Eyes of Australian Consumers

Sustainability is a complex and multifaceted concept that comprises environmental, economic, social, and cultural dimensions. Growing consumer concerns over the impacts of global meat production and consumption have led to increasing interest in sustainability initiatives and the use of sustainability labels. Yet, an understanding of what sustainability means to consumers in the context of meat and how consumers relate production-related credence attributes of chicken meat to sustainability remains limited. Between September 2019 and January 2020, an exploratory research study was conducted using a multi-method approach. Participants completed an online survey before participating in a series of eye-tracking choice tasks followed by in-depth interviews. The study revealed that the environmental dimension of sustainability is most important to consumers’ definition of a “sustainable food system”. Likewise, the sustainability of chicken meat products was most commonly associated with the perceived environmental impact of chicken meat production, followed by animal welfare aspects. Consumers made incorrect inferences about some sustainability labels and these inferences sometimes contributed to positive associations with sustainability. Consumers frequently associated a higher price with higher sustainability, indicating a belief that “doing the right thing” might cost more. This study provides new insights regarding consumers’ perceptions of production-related credence attributes and sustainability labels.

Sustainable food choice motives: The development and cross-country validation of the Sustainable Food Choice Questionnaire (SUS-FCQ)

In view of all kinds of sustainability concerns related to our current diet, it is essential to gain a good understanding of the sustainability motives consumers have for selecting their food. A comprehensive and validated scale to measure sustainability motives within the full range of food choice motives could contribute to this understanding, especially as sustainability is a multi-faceted concept in which the different aspects can sometimes be conflicting. The current paper aims to 1) develop the Sustainable Food Choice Questionnaire (SUS-FCQ) that covers the full concept of sustainability, 2) test which dimensions of sustainable food choice motives can be distinguished and 3) validate the scale as part of the Food Choice Questionnaire in multiple countries. An online survey was completed by 5,116 respondents from five European countries (The Netherlands, Denmark, Czech Republic, France and Italy). The scale was developed with a Dutch sub-sample and validated in all included countries. Exploratory factor analysis followed by confirmatory factor analyses resulted in a two-factor solution. A ‘general sustainability’ dimension (6 items, covering environmental, ethical and animal welfare aspects) and a ‘local & seasonal’ dimension (3 items) were identified. The Sustainable Food Choice Questionnaire shows to be reliable and valid in the five included countries and can be used as an addition to the Food Choice Questionnaire developed by Steptoe and colleagues (1995). The scale is suitable to gain a better understanding of the position of sustainability motives against other motives in consumers food choices and can be used for country comparisons.

Transportation of Animal: Process, Challange and the Effect on Small Ruminant

&lt;p&gt;Livestock transportation is carried out to fullfill the need for consumption as well as for raising the livestock in other areas. The regulation of livestock transportation are not well implemented, and far from the ideal way of livestock transportation, such as the aspects of animal welfare. This paper aims is to describe the transportation process, challenge and its effects on small ruminants. The process of transporting livestock is carried out by preparing thye animal that are going to be transported, and the means of transportation used. Travel distance and road infrastructure conditions provide an affordable connection for the transportation of livestock. Long distances and poor infrastructure conditions can cause stresproblems to livestock transportation. Livestock becomes stres and cortisol levels increased in the blood and physiological responses were affected due to transportation. The Goat Research Institute designed a cage in a truck to transport goats and logistical needs during the trip by land and sea routes and has been used in the distribution of goats. The journey took 1 to 16 days with average goat mortality rate was about 0.3%. Severe impacts during the trip can be overcome by transporting goats with attention to the transportation system and to ensure the welfare of animals during the trip.&lt;/p&gt;

Reviewing the Review: A Pilot Study of the Ethical Review Process of Animal Research in Sweden.

Simple SummaryThe use of research animals is regulated within the EU through Directive 2010/63/EU on the protection of animals used for scientific purposes, as well as through national legislations and guidelines. However, the ethical review process, which all animal research must undergo, has been heavily criticized. This pilot study has analyzed the ethical review process in Sweden, focusing on how well legislative demands are fulfilled by researchers and animal ethics committees. After developing a score sheet, 18 documents (including both applications and decisions) were thoroughly reviewed, and the requests in the application form were compared to legal demands. The results revealed a number of issues concerning how HBA (harm–benefit analysis) was conducted by the committees, application, and review of the 3Rs (Replace, Reduce, Refine), as well as how humane end-points, severity assessment, and the “upper limit” of suffering were implemented and assessed. The study further indicates disconcerting discrepancies between the Swedish application forms for project evaluation, national legislation, and the directive as well as a lack of transparency throughout the review process. These findings risk compliance with the directive, animal welfare, research validity, and public trust. Therefore, a number of suggestions for improvements are provided, and the need for further research is emphasized.The use of animals in research entails a range of societal and ethical issues, and there is widespread consensus that animals are to be kept safe from unnecessary suffering. Therefore, harm done to animals in the name of research has to be carefully regulated and undergo ethical review for approval. Since 2013, this has been enforced within the European Union through Directive 2010/63/EU on the protection of animals used for scientific purposes. However, critics argue that the directive and its implementation by member states do not properly consider all aspects of animal welfare, which risks causing unnecessary animal suffering and decreased public trust in the system. In this pilot study, the ethical review process in Sweden was investigated to determine whether or not the system is in fact flawed, and if so, what may be the underlying cause of this. Through in-depth analysis of 18 applications and decisions of ethical reviews, we found that there are recurring problems within the ethical review process in Sweden. Discrepancies between demands set by legislation and the structure of the application form lead to submitted information being incomplete by design. In turn, this prevents the Animal Ethics Committees from being able to fulfill their task of performing a harm–benefit analysis and ensuring Replacement, Reduction, and Refinement (the 3Rs). Results further showed that a significant number of applications failed to meet legal requirements regarding content. Similarly, no Animal Ethics Committee decision contained any account of evaluation of the 3Rs and a majority failed to include harm–benefit analysis as required by law. Hence, the welfare may be at risk, as well as the fulfilling of the legal requirement of only approving “necessary suffering”. We argue that the results show an unacceptably low level of compliance in the investigated applications with the legal requirement of performing both a harm–benefit analysis and applying the 3Rs within the decision-making process, and that by implication, public insight through transparency is not achieved in these cases. In order to improve the ethical review, the process needs to be restructured, and the legal demands put on both the applicants and the Animal Ethics Committees as such need to be made clear. We further propose a number of improvements, including a revision of the application form. We also encourage future research to further investigate and address issues unearthed by this pilot study.

Happy or healthy? How members of the public prioritise farm animal health and natural behaviours.

The importance given to minimising health issues and promoting natural behaviours is a polarising issue within farm animal welfare. It is predominantly thought that members of the public prioritise animals being able to behave naturally over other aspects of farm animal welfare, such as addressing health issues. However, public perspectives may be more multi-dimensional than is generally thought, with the importance given to these different elements of welfare dependent on the situation and state of the animals in question. To examine this, a factorial survey using vignettes, which experimentally manipulated the different levels of health (high health vs. low health) and natural behaviour provision (high behaviour vs. low behaviour), was completed by a sample (n = 810) representative of the UK population (on age, gender, ethnicity). Contrary to the predominant view, this study found animal health had the greatest effect on participants' judgements, explaining more of the variance in their assessments of animal welfare than any other factor. However, findings also indicated that participants considered animal welfare to be most positive when both health issues are minimised and natural behaviours are promoted. Attitudes to natural behaviours also varied more between participants, with females, individuals who do not (regularly) eat meat and those with a greater belief in animal mind giving greater priority to natural behaviours. In the context of public and private welfare standards seeking to meet public expectations, this study provides important insights into how public perspectives of animal welfare are more nuanced than previously thought, influenced by the context of the animal, the aspect of welfare in question and personal characteristics.

11. Study of Cat’s Welfare Kept at Pet Shops in Gajah Mada Mal Central Jakarta

The aim of this study was to find out correlation between cat’s welfare and caring management in a number of cats kept at pet shops in Gajah Mada mal Central Jakarta, from January to February 2016. This study used a questionnaire with ratings based on five aspects of animal welfare (freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury, and disease, freedom from fear and distress, and freedom to express normal behavior) and through direct observation. Data was analyzed by Correlation Test Chi Square with 95% confidence interval. The result shows that there is a significant correlation (P 0,05) between caring management and animal welfare standart in freedom from pain, injury, and disease aspects, freedom from discomfort aspect, and freedom to express normal behavior with caring management aspects.

In vitro assays for evaluating phytate degradation in non-ruminants: chances and limitations.

The positive effects of phytases on the environment, animal welfare and animal feed costs have resulted in the continuous development and improvement of these enzymes in the non-ruminant feed market. To test the efficacy of these phytases, a large number of experimental animals are necessary, antagonising the animal welfare aspect of these enzymes. In the present review, we summarise the most prominent available in vitro assays for evaluating phytase enzymes and how far they can reduce the number of in vivo experiments. Several in vitro assays exist that differ in their setup, extent and conditions depending on the animal of interest and the research question. With the in vitro assays described, it is not possible to fully replace in vivo trials. However, for the investigation of phytase effects in feedstuffs, the use of an in vitro assay has several advantages. In vitro assays have the potential to be used for ranking feed enzymes and as screening tools. Applying in vitro protocols will result in a reduction in the number of animals or treatments usually necessary for an in vivo trial, thus acting towards the three Rs. © 2020 Society of Chemical Industry.

Farm efficiency related to animal welfare performance and management of sheep farms in marginal areas of Central Italy: a two-stage DEA model

The development of specific actions to increase animal health and welfare is indicated as a strategy to improve the efficiency and sustainability of many livestock systems, including sheep farming. In this paper, efficiency measures are provided to confirm the hypothesis that farms that are higher-performing in terms of animal welfare and management are also more technically efficient. A two-stage Data Envelopment Analysis (DEA) approach was adopted with the following twofold objectives: 1) to evaluate the efficiency and super-efficiency of 76 meat-producing sheep farms situated in marginal lands in central Italy, through DEA and Super-DEA (S-DEA) models; and 2) to assess the influence of animal welfare and management indicators on technical efficiency values through the application of a Tobit regression model. An overall efficiency performance varying within a range of 0.44–1 was estimated, with an average value of 0.80, implying a potential increase of 20% in terms of output production from both management and scale improvements. The ‘pure’ technical inefficiency was found to contribute three times more than scale inefficiency in determining the overall technical inefficiency. Adopting a more extensive farming system and increasing replacement rate were found to affect negatively the efficiency scores. On the other hand, having less than 5% of animals with body condition score beyond acceptable limits, presence of access control structures, well managed lambing pens, and dedicated feed stocking areas resulted in a positive influence on efficiency. Improvements in animal welfare aspects did not appear to be farm-scale-dependent. Highlights DEA and Super-DEA models were applied to assess sheep farm technical efficiency in Central Italy. An overall potential 20% increase in output production was estimated. Animal welfare factors were found to significantly affect efficiency performance.

When more is more: taking advantage of species diversity to move towards sustainable aquaculture

ABSTRACTHuman population growth has increased demand for food products, which is expected to double in coming decades. Until recently, this demand has been met by expanding agricultural area and intensifying agrochemical‐based monoculture of a few species. However, this development pathway has been criticised due to its negative impacts on the environment and other human activities. Therefore, new production practices are needed to meet human food requirements sustainably in the future. Herein, we assert that polyculture practices can ensure the transition of aquaculture towards sustainable development. We review traditional and recent polyculture practices (ponds, recirculated aquaculture systems, integrated multi‐trophic aquaculture, aquaponics, integrated agriculture–aquaculture) to highlight how they improve aquaculture through the coexistence and interactions of species. This overview highlights the importance of species compatibility (i.e. species that can live in the same farming environment without detrimental interactions) and complementarity (i.e. complementary use of available resources and/or commensalism/mutualism) to achieve efficient and ethical aquaculture. Overall, polyculture combines aspects of productivity, environmental protection, resource sharing, and animal welfare. However, several challenges must be addressed to facilitate polyculture development across the world. We developed a four‐step conceptual framework for designing innovative polyculture systems. This framework highlights the importance of (i) using prospective approaches to consider which species to combine, (ii) performing integrated assessment of rearing environments to determine in which farming system a particular combination of species is the most relevant, (iii) developing new tools and strategies to facilitate polyculture system management, and (iv) implementing polyculture innovation for relevant stakeholders involved in aquaculture transitions.

Wild boar behaviour during live-trap capture in a corral-style trap: implications for animal welfare

BackgroundWildlife traps are used in many countries without evaluation of their effect on animal welfare. Trap-capture of wild animals should minimise negative effects on animal welfare, irrespective of whether the animals are trapped for hunting, research, or management purposes. Live-trap capture of wild boar (Sus scrofa) followed by killing inside the trap by gunshot is a recently introduced but disputed hunting method in Sweden. Approval of trap constructions is based on gross necropsy findings of 20 trapped and shot wild boars. For improved animal welfare evaluation, our aim was to study wild boar behaviour during live-trapping in a 16 m2 square corral-style trap. Behavioural assessments were conducted after filming 12 capture events of in total 38 wild boars (five adults, 20 subadults, 13 piglets). Selected behavioural traits were compared with pathological changes (trap-related lesions) found at necropsy of the 20 subadults, to determine if these variables were useful proxies of capture-induced stress in wild boar.ResultsThe wild boars spent less time resting in the evening than in the night and morning. Using Friedman’s ANOVA, there was an overall difference in the time spent foraging. However, we only found a difference between the evening and morning in the Wilcoxon matched pairs test after the Sequential Bonferroni correction, where the wild boars spent more time foraging in the evening than in the morning. Single captured individuals showed more escape behaviours and reacted more strongly to external stimuli than individuals captured in a group. It was more common for animals to charge against the mesh walls of the trap upon human approach compared to upon initial capture when the trap door closed. Trap-related pathological findings due to trauma were documented in 13 of the 20 subadults that were necropsied. Behavioural alterations indicative of capture-induced stress (e.g. charging into the trap walls) were documented in trapped wild boars with no or minor physical injuries (e.g. skin abrasions, subcutaneous haemorrhage).ConclusionsBehavioural assessment provided valuable information for determination of capture-induced stress in wild boar when evaluating live-trapping in a corral-style trap, whereas pathological evaluation through necropsy did not fully reflect the animal welfare aspects of live-trapping. We emphasize the inclusion of species-specific behavioural data assessment for evaluation of capture-related stress during live-trapping and for testing of new trap constructions before approval.

Comparison of different piglet diets in organic agriculture using milk powder, enriched lysine, conventional potato protein or high soybean cake content

AbstractFeeding monogastric livestock in organic agriculture is challenging due to several tradeoffs between animal welfare aspects, resource efficiency, as well as ecological and social sustainability. Organic standards may even increase such conflicts, as is currently the case with upcoming new regulations regarding restrictions of feed sources for organic pigs in Europe. In order to contribute data for balancing reasons to minimize tradeoffs, we compared four different piglet diets, each targeted to reach a high protein quality by either a high proportion of soybean cake (SOY), inclusion of milk powder (MILK), fermentatively produced lysine (LYS) or conventional potato protein (POT). All diets were designed to meet the nutritional requirements of piglets in the best possible way, however they all represented different conflicts with either organic regulations or sustainability goals. In each of five consecutive runs, respectively three litters were assigned to every dietary treatment, resulting in 15 litters per treatment in total. In each litter, seven focus animals were defined. The piglets were studied from birth until 58 days of age. They were weaned at day 46 and sold from the farm at day 58. Piglets were individually weighed at an average age of 3, 21, 43, 50 and 58 days with simultaneous assessment of body condition score (BCS) and prevalence of diarrhea. Feed intake (FI) was recorded litter wise weekly, starting from week three. Feed conversion ratio (FCR) was calculated for the period after weaning. Statistical analysis was executed using linear mixed effect models. Regarding FI, FCR and daily weight gains, no treatment effect was found. Only at day 21, BCS was lower for piglets receiving POT. Prevalence of diarrhea increased after weaning for all treatments. All four tested diets led to similar weight gains and feed conversion in the piglets. Animals fed diet POT recovered better from diarrhea compared to the other treatments. A high soybean cake content or lysine supplementation in the diet was disadvantageous with regard to the occurrence of diarrhea. LYS diet led to signs of threonine deficit, indicating that lysine addition alone may not solve the issue. The addition of milk powder provided no extra benefit. In recognition of the health benefits, the use of 5% potato protein, even if it is sourced from conventional production, must still be considered as a sustainable option for feeding organic piglets. The sustainability implications are discussed in the paper.

Understanding consumers' perceptions towards Iberian pig production and animal welfare

The Spanish market offers a greater variety of Iberian pork products. The aim of this paper is to determine the perception of consumers of several aspects of Iberian pig production and animal welfare depending on the consumers' characteristics. Consumers from two Spanish regions (n = 403) answered a questionnaire about their beliefs and the importance of pig production, their purchase intentions and their willingness to pay. Consumers were segmented according to their level of knowledge about Iberian pig production. The results of this work indicate that consumers have poor knowledge about Iberian pig production. Even so, consumers show a remarkable preference for Iberian products, especially when the animals are reared freely and in natural conditions, giving great importance to animal welfare. Consumer preferences indicate the importance of emphasizing Iberian traditional pig product characteristics on the label to promote their purchase choices.

Role of sustainability attributes and occasion matters in determining consumers’ beef choice

This study aims to evaluate the influence of socio-environmental attributes on the purchase intention of and the willingness to pay for beef, based on data from Brazilian consumers, using a discrete choice analysis model. Different consumption situations were analysed to check the influence of functional versus recreational/hedonic beef choice. Sixteen (16) hypothetical products were generated in eight (8) scenarios regarding the different socio-environmental attributes of beef. The findings confirm the importance of animal welfare and traceability in the decision-making process for beef purchase. The frequency of consumption, gender, and the presence of a known/familiar brand also influence the beef choice when making a functional (day-to-day) purchase, compared to a recreational/hedonic (barbecue) purchase. The study suggests that the beef industry and retailers should better explore various aspects of greenhouse gas emissions and animal welfare and highlight them in their communication strategies. Investigating the trade-offs between socio-environmental attributes allows a more in-depth evaluation of these attributes and contributes to the literature.
