Animal welfare and meat quality: The perspective of Uruguay,a “small” exporter country

Public sensitivity towards animal welfare has risen in recent years. Uruguay is a primary meat exporter. Therefore, it is compulsory not only to provide good quality and safe meat, but also to project a welfare friendly image. Uruguayan meat production systems are mainly based on rangeland pastures but, due to international meat prices and the opening of new markets, intensive fattening systems increased. These systems include a wide range of feeding alternatives between pasture and concentrate utilization, involving differences in terms of animal welfare, carcass and meat quality, that require to be studied. Accordingly, some husbandry practices associated mainly with extensive systems must be evaluated, as well as their applicability to international recommendations related to pre-slaughter handling which may not be suitable for local conditions. In the present paper we share scientific results related to the impact of different production systems, husbandry practices and pre-slaughter procedures associated to animal welfare and meat quality in Uruguayan conditions.     

Welfare issues of donkey (Equus asinus): a checklist based on the five freedoms

Studies on the welfare of donkey (Equus asinus) have developed slowly, because considered very rustic animals, reared prevalently under extensive production systems and widespread mainly in marginal areas. The diffusion of extensive breeding of this species has led to the belief that donkey did not need any welfare assessment. More recently, the scenario has changed, due to a gradual diffusion of intensive and semi-intensive production systems, especially in highly productive dairy breeds, to the growing concern of consumers about the life conditions of farmed animals, and to the issuing of a number of national and European rules / laws on the safety of animal products and well-being of farmed livestock. Relating with the importance of this species on food farming industry, the Author underlines the missing of specific recommendations concerning the welfare of farmed donkey. In absence of common criteria and guidelines, it is possible to make reference to the well-known “five freedoms”. This paper will review the main welfare issues of donkeys and the following aspects will be considered: nutrition, housing and management, clinical problems, behaviour problems.     

Prospects for sustainability of pig production in relation to climate change and novel feed resources

Pig production systems provide multiple benefits to humans. However, the global increase in meat consumption has profound consequences for our earth. This perspective describes two alternative scenarios for improving the sustainability of future pig production systems. The first scenario is a high input–high output system based on sustainable intensification, maximizing animal protein production efficiency on a limited land surface at the same time as minimizing environmental impacts. The second scenario is a reduced input–reduced output system based on selecting animals that are more robust to climate change and are better adapted to transform low quality feed (local feeds, feedstuff co-products, food waste) into meat. However, in contrast to the first scenario, the latter scenario results in reduced predicted yields, reduced production efficiency and possibly increased costs to the consumer. National evaluation of the availability of local feed and feedstuff co-product alternatives, determination of limits to feed sourced from international markets, available land for crop and livestock production, desired production levels, and a willingness to politically enforce policies through subsidies and/or penalties are some of the considerations to combine these two scenarios. Given future novel sustainable alternatives to livestock animal protein, it may become reasonable to move towards an added general premium price on ‘protein from livestock animals’ to the benefit of promoting higher incomes to farmers at the same time as covering the extra costs of, politically enforced, welfare of livestock animals in sustainable production systems. © 2020 The Authors.

Production systems and influence on eating quality of pork

The present paper reviews the available information on the eating quality of pork from the perspective of production systems considered at farm level. Among the specifications differentiating systems having a claim on eating quality, breed, feeding strategy, rearing conditions and slaughter age/weight of the pigs may influence pork eating quality. Specific genetic X environment interactions such as the use of slow growing-fat local breeds reared in extensive conditions, as encountered in local Mediterranean systems, lead to high eating quality of pork and pork products Organic production per se has little influence on the eating quality of pork. Welfare-oriented specifications such as enriched living environment, outdoor access or free-range rearing have limited consequences on pork quality. Because boar taint negatively impacts the consumer acceptability of pork, a total ban on castration to improve animal welfare would be a real challenge for the management of pork quality in those countries where entire male pig production is not currently common.     

Dairy animal welfare: current and needed research

Of 25 milestones in dairy animal welfare, 10 were linked to laws and regulations, 9 to research, education, and development, 4 to books and publications, and 2 to human error (accidents). Animal rightists have attacked the dairy industry because of farm conditions, bovine somatotropin, overproduction of milk, dairy lobbies, and advertising of milk products. Evidence from Europe suggests that animal welfare has been largely promoted as a sociopolitical issue by nonagriculturalists. Codes, guidelines, and recommendations are well-established for northern Europe. The American Veterinary Medical Association Animal Welfare Committee has prepared the pamphlet on food animal welfare and addressed specific bovine welfare issues in its guide for veal calf care and production. From 1978 to 1986, only four US experiment station projects were concerned with dairy animal welfare. Needed research includes studying learned helplessness; analysis and economics of alternative husbandry systems for veal calves (and cows) freestall design and surfaces; and shade, cooling, and misting of mangers and holding pens prior to entering the parlor. Alert caretakers are encouraged to read behavior signals of cattle. Increased standing of cattle is often taken now as a sign of discomfort or discontent in studies of cow and calf confinement. Criteria that should be considered in assessing welfare or well-being are behavior, health, musculoskeletal soundness, productivity, physiological and biochemical characteristics, and reproduction.     

Welfare,performance and meat quality of fattening pigs in alternative housing and management systems: a review

Conventional husbandry systems for pork production are scrutinized by members of the general public as well as the scientific community. As a response, alternative forms of pig production, such as outdoor housing, organic farming and environmental enrichment are gaining interest. The question arises whether these production systems are indeed able to improve the welfare and health status of the animals, and whether these production systems alter production characteristics and meat or carcass traits. Measures of poor welfare have been described, but evaluating overall welfare is difficult. Certain parameters of alternative housing will improve welfare in some ways but, simultaneously, other welfare problems are inflated, and the weighting of each of these problems is very subjective. Alternative housing systems allow pigs to display species‐specific behaviour and decrease the occurrence of abnormal behaviours by acting on several parameters: indoor versus outdoor housing, floor space/density, floor type, and provision of bedding or other types of environmental enrichment. Evaluating alternative housing systems should be done by looking at all the welfare‐improving factors and the cost of alleviating welfare‐decreasing problems in a given production system. Data in the literature on growth, meat and carcass traits in alternative production systems, are inconsistent, indicating that other factors can play an important role. However, as equal, or in some cases even better, performance can be attained in certain production systems that meet concerns of animal welfare scientists and members of the general public, alternative production forms may be considered preferable.

Extrinsic attributes of red meat as indicators of quality in Europe: an application for market segmentation

Consumers give increasing importance to the extrinsic quality attributes of meat in response to rising concerns on safety, health, convenience, ethical factors, etc. The role that attributes such as animal feeding assurance, environmentally friendly production, respect for the animal welfare, etc. play in the consumer quality evaluation process has not been studied enough. The objectives of this article were: to evaluate the importance of several extrinsic quality attributes of red meat to consumers in five European regions; to analyse the relationships between the attitude towards these attributes, available cues and factors or motivations that are important to consumers when buying meat; and to identify groups or segments of consumers according to the importance of extrinsic quality attributes. The most important extrinsic attributes found were animal feeding and origin. Environmentally friendly production and animal welfare considerations were also important. Animal feed assurance was an indicator of safety and nutritious/ healthy meat but origin was not. For some groups of consumers, respect for the environment and animal welfare were also related to healthy/safe meat. The range of attitudes consumers hold towards extrinsic attributes could constitute an opportunity to develop consumer-led meat products and further market segmentation.     

Invited review: ruminating conscientiously: scientific and socio-ethical challenges for US dairy production

Despite the predominantly positive depictions of dairy production, public concern about farm animal production practices in the United States is currently higher than at any point in recent history. Many standard industry practices, including some used by the US dairy industries, are increasingly challenged not just on scientific grounds, but also on ethical grounds. Concerns include the environmental impacts and sustainability of modern farm animal production practices, food safety and security, and the increasingly complex issue of animal welfare. As the impetus increases to achieve broad stakeholder engagement in discussions of US food policy, understanding and addressing the ethical concerns associated with contemporary dairy production is critically important to ensure the industry's autonomy and long-term viability. Animal welfare assessment or accountability tools such as the Ethical Matrix or Campbell's Ethics Assessment Process can provide a structured, transparent method of making appropriate ethical choices about the care and welfare of farm animals that are also scientifically grounded.     

Animal welfare and the dairy industry

Although the dairy cow plays an integral role in the ecology of sound food production, its welfare, as well as economic efficiencies and soundness of food production under modern industrial-scale systems of management, are questioned. Major areas of welfare concern are identified and reforms and ethical guidelines suggested.     

Advances in the industrial production of halal and kosher red meat

The worldwide volume and value of trade in halal and kosher meat and co-products are huge. Muslim countries alone consumed meat estimated to be worth USD 57.2 billion in 2008. The halal and kosher principles that govern the production of red meat have many similarities, as well as some fundamental differences. Perhaps the most significant difference is that at the time of slaughter, the animal needs only to be alive to meet the minimum halal requirement, but must be both alive and conscious for kosher. It is for this reason that reversible pre-slaughter stunning is acceptable only for halal meat, although a compromise form of post-slaughter stunning is now considered kosher in some countries. Extensive research on animal physiology and welfare has characterised and optimised the methods for stunning livestock, and enabled advancement in associated technologies. This forms the basis for harmonising the religious and secular requirements for the protection of animal welfare at slaughter. These technologies and the associated processing practices for the industrial production of halal and kosher meat are reviewed in this paper.     

Internalizing the Societal Costs of Agricultural Production

Societies and social groups within them are becoming aware that food and fibre are not gifts of nature that come to us cost-free from the natural world because their production involves consumption of renewable and non-renewable resources as well as expenses for capital and variable inputs in the production process, plus outlays for transportation, processing, marketing, and food preparation. The essence of food and fibre production is that on one hand, the key production resources (seeds, tubers, soil, manures, and rain water) are renewable resources, thus potentially enabling agriculture to be a highly sustainable activity. On the other hand, agriculture has some actual or potential characteristics of an extractive industry, similar to mining, and accordingly has the potential to be highly unsustainable. In addition, food and fibre production may involve long-term non-environmental costs (e.g. impacts on workers, communities, regions, and consumers) to a greater or lesser degree. In this paper, I use the expression “societal costs” of agriculture to pertain to adverse impacts of agrofood systems on human health, environmental quality, and the welfare and livelihoods of social groups. (A focus on the societal costs of food and fibre production does not, of course, involve a presumption that the benefits of this production, both to humans and non-human portions of the biosphere, are insignificant.)     

Animal welfare assessment at slaughter in Europe: moving from inputs to outputs

Producers, retailers and other food chain actors increasingly recognize that consumer concerns for good animal welfare represent a business opportunity that could be profitably incorporated into their commercial strategies. Therefore, during the last decade, numerous trade groups (producers, processors, retailers and restaurant chains) have developed certification systems with their suppliers which include elements of animal welfare. The Welfare Quality® project has developed an integrated and standardised welfare assessment system based on twelve welfare criteria grouped into four main principles (good feeding, good housing, good health and appropriate behaviour) according to how they are experienced by animals. One of the innovations of the Welfare Quality® assessment system is that it focuses more on outcome measures (e.g. directly related to animal body condition, health aspects, injuries, behaviour, etc.). This paper has the objective to discuss the rationale behind the welfare assessment and to describe the Welfare Quality® assessment of pigs and cattle at the slaughterhouse.

Strategies to promote farm animal welfare in Latin America and their effects on carcass and meat quality traits

Several initiatives, including research and development, increasing stakeholders' awareness and application of legislation and recommendation, have been carried out in Latin America to promote animal welfare and meat quality. Most activities focused on the impact of pre-slaughter conditions (facilities, equipment and handling procedures) on animal welfare and meat quality. The results are encouraging; data from Brazil, Chile and Uruguay showed that the application of the improved pre-slaughter handling practices reduced aggressive handling and the incidence of bruised carcasses at slaughter in cattle and pigs. These outcomes stimulated some to apply animal welfare concepts in livestock handling within the meat production chain as shown by the increasing demand for personnel training on the best. To attend this demand is important to expand local studies on farm animal welfare and to set up (or maintain) an efficient system for knowledge transfer to all stakeholders in the Latin America meat production chains. However, it is clear that to promote the long-term progress in this field is important to deliver practical solutions, assuring that they match the technical and financial conditions of those who are the target of training programs.     

Evaluation of Performance Measurement Instruments on Their Use for Food Quality Systems

Due to regular challenges of food safety, consumers put high demands on the performance of food quality systems. To deal with these requirements, food manufacturers need effective quality management. Performance of food quality systems can be partly realized by quality assurance systems, such as HACCP (hazard analysis and critical control point), ISO (international organization for standardization), and BRC (british retail consortium). However, it is still unknown to what extent these systems factually contribute to the realization of quality in the wider sense. Therefore, an instrument is needed that measures the effectiveness of quality systems.

This article describes the evaluation of instruments on their suitability for the development of a diagnostic instrument that measures the effectiveness of food quality systems. For this evaluation, perspectives of quality, typical characteristics of agrifood production, quantification, and performance measurement of quality management were studied.

Instruments that measure the performance of both quality management and production quality were identified and evaluated on the basis of the defined criteria. The criteria for the performance of production quality were 6 quality dimensions, i.e., product quality, availability, costs, flexibility, reliability, and service. The criteria for performance of quality management were analyses of the relationships between quality management, context of the organization, and production quality, a normative procedure, validation, applicability, classification, and a process approach. Finally, for the final instrument, the evaluation resulted in an integrated approach i.e., a technomanagerial approach, and 3 suitable instruments i.e., Wageningen Management Approach, Extended Quality Triangle, and the quality concept of Noori and Radford.     

Different shades of grey: Compromise products to encourage animal friendly consumption

Contemporary production and consumption are often characterised by negative externalities, for example regarding animal welfare. Despite consumer concerns about animal welfare standards in livestock production systems, the market share of organic meat is still low. The current paper investigates to what extent a more differentiated product assortment including “compromise alternatives”, providing consumers with more options to trade-off animal welfare against other attributes, increases the choice share of meat produced at beyond-regulatory standards for animal welfare. Results from a choice experiment in The Netherlands reveal considerable heterogeneity in consumer preferences regarding the trade-off between animal welfare level and price level. Two out of six segments, typically consumers with a lower education level and shoppers at discount supermarkets, are not or hardly prepared to pay a price premium for welfare enhanced meat. Two other segments show a preference for small increases in animal welfare level and associated costs. The remaining two other segments seem to reflect “protestors” against mainstream meat production in that they hold negative attitudes, beliefs and feelings regarding the consumption of conventionally-produced meat, either by turning to meat produced at high animal welfare standards (including meat replacement products) or by reducing meat consumption. It is concluded that an assortment that better caters for this heterogeneity in consumer preference by including “compromise meat products” is of the benefit to both the individual consumer (preferences), the animal (animal welfare levels) and the meat sector (clientele).     

Standpunkte, Praktiken und Kenntnisstand zur Ferkelkastration in Europa (PIGCAS) – Projektziele und erste Ergebnisse

Most of the male piglets in the EU are castrated. According to the current EU legislation, surgical castration can be performed without anaesthesia up to the age of 7 days. A report of the European Food Safety Authority (EFSA) on the welfare aspects in relation to the castration of pigs has underlined the need for further research. As a follow up, the EU has launched a two-year project (Specific Support Action PIGCAS) within the 6^th EU Framework Programme, starting in January 2007. “PIGCAS” is the acronym for “Attitudes, practices and state of the art regarding piglet castration in Europe”. The main objectives are: [A] to collect information on the attitudes of the various stakeholders (consumer groups, NGOs and industry stakeholders); [B] to collect information on the extent of the practice of castration of piglets (male or female) within the EU and the conditions under which castration is performed; [C] to evaluate research work and other sources of information, in order to examine surgical castration without anaesthesia and its possible alternatives from different perspectives and derive research priorities; and [D] to integrate the collected information and evaluation in a report providing support for EU policy in the field of research and legislation. Preliminary results are now available on objectives [A] and [B]. When referring to the alternatives to surgical castration, one has to distinguish between short-term and long-term solutions. Surgical castration with anaesthesia was mentioned by most of the stakeholders as a short-term alternative. Genetic control of boar taint and sperm sexing to select only females for pork production are considered as long-term alternatives. Current practices of castration and levels of acceptability vary substantially between and within countries and regions. The current research focuses on practical methods for acute and postoperative pain alleviation and analyses the complex consequences of raising entire males or immunocastrated boars. Considering the different dimensions (attitudes, extent of practice, animal welfare, pork quality and economy) of importance, it is intended to propose to the EU short and long-term strategies to handle this problem.

Consumer choice of broiler meat: The effects of country of origin and production methods

An increasing interest and concern among consumers in the ways in which food is produced has led to a need for differentiation in production methods in directions valued by consumers. In this study we used a choice experiment to analyse the importance of the production method, such as organic production and methods emphasising animal welfare or consumer health, and country of origin on the selection of broiler meat by Finnish consumers. The results revealed very strong positive perceptions of domestically produced broiler products. The effect of production method was significant but minor. Emphasising animal welfare in production particularly increased the probability of consumer choice. We also tested the effect of providing production information either in labels or verbally, and found that well-established labels have positive impacts whereas non-familiar labels may be counter-productive. Latent class analysis revealed the heterogeneity of consumer preferences, but did not facilitate the profiling of consumer groups based on socioeconomic data.     

Effect of information about animal welfare on consumer willingness to pay for yogurt

This study aimed to verify whether consumers confirm their willingness to pay extra costs for higher animal welfare standards in a situation where a potential purchase performed by consumers, such as the Vickrey auction, is used. A 104-member consumer panel was asked to rate its willingness to pay (WTP) for plain and low-fat yogurts in 3 information conditions: tasting without information (blind WTP), information about animal welfare without tasting (expected WTP), tasting with information about animal welfare (actual WTP). Information was provided to the consumers under the form of labels indicating the level of animal cleanliness and freedom of movement (5-point scale, from poor to very good). Consumers were influenced by information about low standards of animal welfare (low cleanliness and low freedom of movement) and moved their willingness to pay in the direction of their expectations. However, the discrepancy between expectancy and actual WTP was not totally assimilated, indicating that WTP was also expressed in relation to other aspects (e.g., the sensory properties of the products). Conversely, the information concerning high standards of animal welfare (high cleanliness and high freedom of movement) was able to affect expectancy but had an effect on actual WTP only when the most acceptable yogurt was offered to the consumers. In the case of discordant information on animal welfare, partly indicating high levels of welfare (freedom of movements) and low levels of welfare (cleanliness), expected WTP was always lower than blind WTP. However, when the least acceptable product was presented, they completely assimilated their actual WTP to the expectations. Conversely, with the most acceptable yogurt, no assimilation occurred and sensory properties prevailed in orienting consumer WTP. Within each product, consumers expressed a higher WTP for products with labels indicating high welfare standards as compared with yogurts with labels reporting intermediate and low welfare standard. These results show that information about animal welfare, if given to the consumers, can be a major determinant of consumer WTP for animal-based food products. However, information about high standards of animal welfare should be paired with products presenting a good eating quality.     

Animal welfare: An animal science approach

Increasing world population and demand for animal-derived protein puts pressure on animal production to meet this demand. For this purpose animal breeding efforts were conducted to obtain the maximum yield that the genetic makeup of the animals permits. Under the influence of economics which is the driving force behind animal production, animal farming became more concentrated and controlled which resulted in rearing animals under confinement. Since more attention was given on economics and yield per animal, animal welfare and behavior were neglected. Animal welfare which can be defined as providing environmental conditions in which animals can display all their natural behaviors in nature started gaining importance in recent years. This does not necessarily mean that animals provided with good management practices would have better welfare conditions as some animals may be distressed even though they are in good environmental conditions. Consumers are willing to pay more for welfare-friendly products (e.g.: free range vs caged egg) and this will change the animal production practices in the future. Thus animal scientists will have to adapt themselves for the changing animal welfare rules and regulations that differ for farm animal species and countries. In this review paper, animal welfare is discussed from an animal science standpoint.
