This review, which focuses on foie gras production from ducks in France, highlights welfare problems that may arise in the final (third) stage of production, when force-feeding occurs and which lasts 12 to 15 days. Welfare problems arising in the first two stages are also considered. The male mulard duck, a non-migratory hybrid between a muscovy drake (Cairina moschata) and a female domestic duck (Anas platyrhynchos), is used most frequently despite being fearful, nervous and maladapted to force-feeding conditions. During the period of force-feeding, mortality is 2 to 6%, higher than in fattening units for meat production. Welfare deteriorates markedly as ducks progress through the three production stages. Posture and gait abnormalities and wing lesions develop, and contact dermatitis is widespread and often severe. Oesophagitis and other injuries are documented. Steatosis and other liver changes are pathological and can limit duck survival. Group housing necessitates the use of crowd-gates to facilitate force-feeding of birds, which show aversive behaviour towards the force-feeder. Cages are small, with a mesh floor without litter or a rest area. Access to open water for bathing or full immersion of the head may be insufficient and make thermoregulation difficult. We conclude that forcefeeding causes very poor welfare in ducks and should not be practised. Should foie gras production without force-feeding become possible, duck livers should not reach a weight at which there are pathological effects. Inadequate housing and management conditions should be prevented by establishing limits for the prevalences of contact dermatitis (foot-pad and digits), breast lesions and gait abnormalities, which should not be exceeded prior to slaughter. Limits should also be established for the prevalence of wing and other body lesions after slaughter.

This paper discusses the ethical implications of applying the concept of behavioural needs to captive animals. This is done on the basis of analysing the scientific literature on farmed mink and their possible need for swimming. In the wild, American mink (Mustela vison) are semi-aquatic predators, lending initial support to the claim that captive mink with no access to adequate swimming facilities experience a thwarted behavioural need. Scientific studies show a disparate picture. Consumer-demand experiments, where the animals have been conditioned to work for environmental resources, consistently show that mink place high value on swimming water, whereas other studies indicate the opposite, which has led scientists to question whether this preference constitutes a genuine behavioural need. In this paper, we take a methodological turn and discuss whether the oft-used concept of behavioural needs provides the best possible account of what is indispensable to an animal. Seen from a more complex understanding of behavioural needs, we suggest that lack of swimming opportunities for farmed mink constitutes a welfare problem. Further, it is argued that the decision of which paradigm to use in research on animal needs has not only ethical consequences, but is in itself a value-based choice.

Animal welfare science is a burgeoning field, but research on cetaceans (whales, dolphins and porpoises) is lacking. Bottlenose dolphins (Tursiops truncatus) are the most well-known and studied cetaceans, particularly in captivity, and thus are used in this review as a model for other cetacean species. Despite the public interest and need for such research, studies specifically investigating dolphin welfare are lacking. This review uses the three broad categories of behaviour, health, and cognition, to discuss how dolphin welfare has been assessed thus far, and could be assessed in future. We present welfare indicators validated in other species that could be applied to dolphins, including innovative measures, such as cognitive appraisal of emotions. We provide a summary of practical recommendations for validating the indicators of bottlenose dolphin welfare. This paper aims to stimulate further research into dolphin welfare which could improve the lives of the animals themselves and ultimately support regulatory decisions. We recommend uniting expertise in cetology and welfare science in order to develop a holistic approach to dolphin welfare assessment.

Family farming is still the main source of income for many people in the tropical regions of the world. At the same time, modern society is quickly becoming more aware of the welfare of animals for human consumption. The main objective of this study was to illustrate the need to modify certain aspects of the original Welfare Quality® (WQ) protocols developed by the EU-funded WQ project, under the conditions of small community farmers in the tropics. Thirty-four dual purpose farms in the State of Chiapas, Mexico, which had their main production focus on milk but for whom beef production was also of significant value, were evaluated utilising a merged version of the WQ protocols for dairy and beef cattle. Based on their average score, the farms obtained at least an acceptable level in each indicator of welfare. However, after merging indicators from the dairy and beef cattle protocols of WQ in order to adjust it to the prevailing conditions in the tropics, a number of sections are not applicable. This is particularly true of the section related to good housing, where most of the items do not apply due to the absence of infrastructure; the farms obtained a very high score in this section but further studies to verify whether this reflects an accurate assessment of the welfare status should be carried out. In general, the approach of the WQ protocol was useful, however certain aspects are quite different from the conventional intensive farming systems predominantly used in Europe and there is a need to implement a number of modifications.

The study of farm animal behaviour is a critical tool for assessing animal welfare. Collecting behavioural data with continuous sampling or short scan sampling intervals (eg every 60th second) is considered ideal as this provides the most complete and accurate dataset; however, these methods are also time and labour intensive. Longer sampling intervals provide an alternative in order to increase efficiency, but these require validation to ensure accurate estimation of the data. This study aims to validate scan sampling intervals for lambs (Ovis aries) housed on pasture. Grazing, lying, standing, drinking, locomotion, and mineral consumption were evaluated from six pens of crossbred lambs (six lambs per pen) for 15 h. Data from 1-min instantaneous scan sampling were compared with data from instantaneous scan sampling intervals of 5, 10, 15, and 20 min in two statistical tests: generalised linear mixed model and regression analysis. Using the mixed model, the percentage of time each behaviour was performed did not differ amongst sampling intervals for all behaviours except grazing, which was statistically different at 20-min intervals. Using regression analysis, lying and grazing estimations were accurate up to 20-min intervals, and standing was accurate at 10- and 20-min intervals only. Locomotion, mineral consumption, and drinking demonstrated poor associations for all tested intervals. The results from this study suggest that a 10-min instantaneous scan sampling interval will accurately estimate lying, grazing, and standing behaviour for lambs on pasture. This validation will assist with the efficiency of future data collection in lamb behaviour and welfare research.

How and why dog owners select a specific breed may impact upon the health of the dog they acquire, and upon the wider health of the breed they select. Brachycephalic breeds are rapidly increasing in popularity despite increasing evidence linking brachycephalism with chronic and severe health conditions. This study used a questionnaire to explore pre-, during and post-purchase behaviours and attitudes of dog-owners who own popular brachycephalic dog breeds (n = 3 breeds) compared to popular non-brachycephalic dog breeds (n = 7 breeds). The survey received 1,427 valid responses. Brachycephalic breed owners were younger, more likely to live with children, and to be buying their chosen breed for the first time. The factor that most highly influenced brachycephalic owners’ decisions to buy their breed was appearance, followed by breed size suited to lifestyle, good dog breed for children and good companion breed. Perceived health of the breed was less influential in decision-making for brachycephalic owners compared to non-brachycephalic owners. The way in which owners acquired their dog differed by breed type, with brachycephalic owners more likely to use puppyselling websites to find their dog, less likely to see either parent of their puppy, and less likely to ask to see any health records. Despite many brachycephalic breed health issues being directly related to conformation, appearance remains the most significant determinant in why people desire these breeds. More targeted educational interventions are needed to change buyer attitudes and, if ineffective, other more direct mechanisms (eg legislation) may be required to protect canine welfare.

The Welfare Quality® project was one of the largest research undertakings into animal welfare. Despite animal-based measures (ABMs) being increasingly preferred over resource-based measures (non-ABMs), the Welfare Quality® protocol (WQ) for dairy cattle has a non-ABM, Ease of Movement that classifies housing systems using a threshold of 100 days of access to pasture or, inversely, of 265 days tethered. Since traditional transhumance to alpine pastures lasts for approximately 90 days most farms tend to be classified as having a year-round tie-stall system by the WQ. The aim of this study was two-fold: to discuss the appropriateness of using non-ABMs and related thresholds in welfare scoring and to classify mountain dairy farms using ABM records. Initially, a comparison was made with scores obtained using the WQ protocol in farms where cows were: i) tethered all year; and ii) tethered but having regular exercise or reared in loose-housing systems. No difference in terms of welfare was detected between groups of farms regarding their housing systems, thus we investigated welfare focusing on ABMs. Therefore, farms were grouped into four clusters, according to their ABMs. The results indicated that good ABM scores can be obtained in most traditional mountain farms where cows are tethered for around 275 days a year and have access to highland pasture for the remaining 90 days. In this study, ABMs were effective tools for classifying mountain farms according to their welfare status and for informing targeted action to improve dairy cow welfare.

The Welfare Quality® (WQ) project developed protocols as international standards for farm animal welfare assessment. For dairy cattle, the WQ protocol may be performed any time during the indoor period when the herd has no access to pasture. However, timing of welfare assessments during the indoor period might influence the outcome, as pasture access influences many welfare aspects and such effects are likely to carry over to the beginning of the indoor period. In order to test this hypothesis, we assessed ten herds at both the beginning and end of the same indoor period. Assessment at the end of the indoor period resulted in a higher prevalence of the following welfare measures: severely lame cows, mild integument alterations, coughs per cow per hour, diarrhoea, and vulvar discharge. In addition, at the end of the indoor period, the mortality rate was higher and the Qualitative Behaviour Assessment (QBA) score was worse, but there were fewer cows with dirty udders and mean time to lie down was lower. This led to worse scores on the criterion and principle levels of WQ integration, but resulted in a lower welfare categorisation for one of the herds only. The better scores for several aspects of health and for the QBA at the beginning of the indoor period not only confirm the carryover of positive effects of access to pasture, but also imply a need for careful consideration of the timing and frequency of WQ assessments of herds that are housed outdoors for part of the year.

Although the number of rabbits (Oryctolagus cuniculus) produced in Europe is important, they are under-represented in welfare research. Studies on the effects of housing conditions have focused on performance and mortality. We conducted a meta-analysis to further understand the impact of the housing environment on growing rabbits. Whilst providing a robust quantifiable review, meta-analyses are restricted to existing literature. We included information on behaviour, mortality and performance. Twenty-seven peer-reviewed and conference publications, with a total of 99 experimental treatments, were used. We collected information about rabbit age, bodyweight, sex and breed; allometric space allowance, pen height, group size, environmental temperature, floor type, substrate and enrichment use, lighting, diet and medicated feed. Predictive equations for each response variable were calculated using multiple regression models. Higher space allowance was found to increase locomotor and social activity, and to reduce resting and comfort behaviour. Restricted pen height increased ingestive behaviour; comfort behaviours decreased as space allowance increased, although these might have been confounded with self-directed behaviours in literature. Mortality remained stable at varying space allowances, but increased with larger group sizes and enrichment objects. Growth rate, feed intake and feed conversion were reduced with higher space allowances and larger group sizes, and by provision of substrate and enrichment objects. Findings suggest that higher space allowance and unrestricted pen height are beneficial for rabbit behaviour, but might have undesired consequences if considered independent from other aspects. The challenge of promoting welfare in commercial conditions was highlighted, as a number of parameters which improved behavioural expression reduced performance. In certain cases welfare inputs complemented performance, including providing non-medicated feed and higher space allowance in cooler climates. Although our results should be interpreted with caution given the limitations of the included variables, they are expected to contribute to the improvement of current and new rabbit housing systems to optimise welfare.

The relationship between public attitudes toward animals and human demographics has been well documented during the last few decades, but the influence of human ethical ideologies on public attitudes toward animals and animal welfare has been rarely investigated, especially in developing countries, such as China. The present study introduced two scales (Animal Issue Scale [AIS] and Animal Attitude Scale [AAS]) to investigate the Chinese people's attitudes toward animals and the manner in which their outlook related to ethical ideologies (idealism and relativism), which classified people into four ethical positions: situationists, subjectivists, absolutists and exceptionists. Moreover, it also showed how ethical ideologies and their interaction with human demographics influence respondents’ attitudes toward animals. The results of an online questionnaire (n = 504) distributed throughout China suggest that compared with middle-aged and old respondents, the young demonstrated significantly more positive attitudes toward animals. Absolutists showed the most positive attitudes toward animals, while subjectivists showed the least. People's attitudes toward animals were positively affected by idealism, which confirms previous findings in developed countries. However, people's attitudes toward animals were negatively affected by relativism, which is inconsistent with findings in developed countries, showing that ethical relativism failed to influence attitudes toward animals. Our results indicate that the same mechanisms underlying the effect of ethical idealism on attitudes toward animals might work in different countries to increase awareness on animal welfare. However, the manner in which ethical relativism influences attitudes toward animals may differ between developed and developing countries.
