Concern for elephant welfare in zoological facilities has prompted a number of exhibit and management modifications, including those involving enrichment. Knowledge of how these changes impact indicators of welfare, such as elephant movement and behaviour, is crucial for continued improvement of elephant husbandry and care. The present study used observations and GPS-collected data to determine the effects of available space and food presentation on the walking distance and behaviour of thirteen African elephants (Loxodonta africana), which had a dominance structure ascertained by animal care staff at the San Diego Zoo Safari Park (SDZSP). This facility has two exhibits of approximately equal size. Three treatments were created to assess the effects of food and space enrichment: (i) access to half of the exhibit with food (Half); (ii) access to the entire exhibit with food in one yard (Both/Half); and (iii) access to the entire exhibit with food in both yards (Both). For Half and Both/Half, food was presented in each yard for an equal number of trials. Significant differences across treatments were revealed for average total walking distances but this was not found between any two given treatments. Walking distance varied among elephants belonging to different dominance groups, with middle-ranked elephants taking the most advantage of a larger available space. Behaviour did not differ across treatments, but the change in behavioural diversity from one treatment to another was significant for subordinate elephants. The information obtained from this study has direct implications for the management of the SDZSP elephants and for other facilities looking to increase walking distance or subordinate behavioural diversity.

This paper focuses on the reliability of the multi-criteria evaluation model included in the Welfare Quality® protocol for growing pigs to aggregate the animal-based indicators, first to criteria, then to principle level and finally to an overall welfare score. This assessment was carried out in a practical application study on a sample of 24 farms in Germany. Altogether, 102 protocol assessments were carried out in repeated visits to these farms in order to evaluate the inter-observer and test-retest repeatability of the overall scores calculated by the multi-criteria evaluation system. Reliability is then assessed by the calculation of different reliability and agreement parameters: Spearman Rank Correlation Coefficients (RS), Intraclass Correlation Coefficients (ICC), Smallest Detectable Changes (SDC) and Limits of Agreement (LoA). Inter-observer repeatability was insufficient for the criteria comfort around resting, absence of injuries, expression of social behaviours, expression of other behaviours, good human-animal relationship and positive emotional state as well as for the principles good housing and appropriate behaviour. This is probably due in the main to insufficient repeatability of the underlying indicators that have been revealed in previous studies. Test-retest repeatability is predominantly insufficient. Overall, the present results highlight the importance of absolutely reliable indicators at the baseline level. Furthermore, it could be shown that the calculation procedure is partly incorrect and consequently needs correction. Therefore, this study is an important contribution to the future progression of the Welfare Quality® protocols and animal welfare assessment tools in general.

The objective of this study was to evaluate the use of flavoured ropes as environmental enrichment for individually housed pigs (Sus scrofa). A 4 × 4 Latin square experimental design was utilised to evaluate the effects of four rope flavour treatments on 24 individually penned gilts: i) water, ii) salt water solution; iii) sugar water solution; and iv) apple juice. Cotton rope was soaked in the assigned treatment solution for 30 min on day 1 of each treatment. The rope was tied to an overhead bar at 1000h on day 1 and removed at 1900h on day 2. The following day, gilts received a different treatment using the same methodology. Gilts were videorecorded one day before treatments were given (baseline) and throughout the study. The video was analysed for enrichment interaction, eating behaviour, and posture using a 2-min scan sample interval between 0700 and 1900h. The addition of sugar flavour increased enrichment interaction compared to apple and salt flavours but did not differ compared to water treatment. Furthermore, gilts interacted with enrichment 61% more the first day the enrichment flavour treatment was provided compared to the second. Gilts given rope enrichment spent less time lying and more time sitting compared to when no enrichment was provided. The results of this study suggest that while the addition of flavours to cotton ropes caused minor changes in enrichment interaction and behaviour, provision of rope enrichment was beneficial for increasing activity in stalled gilts.

Undesirable behaviours (UBs) are common in dogs and can jeopardise animal and human health, leading to dog abandonment and euthanasia. Dogs exhibiting UBs may have compromised welfare from underlying emotional motivations for the behaviour (eg anxiety) or from the methods used by owners to resolve the problem (eg aversive techniques). The objective of this study was to estimate proportional mortality due to UBs and risk factors for death due to UBs, including death from road traffic accidents, in dogs under three years of age attending primary-care veterinary practices in England from 2009-2014. Cases were identified by searching de-identified electronic patient records from primary-care veterinary practices participating in the VetCompass Programme. The findings highlight that dogs under three years of age are at a proportionately high risk of death due to UBs (33.7%) compared with other specific causes of death (eg gastrointestinal issues: 14.5%). Male dogs had 1.40x the odds of death from UB compared with females. The proportional mortality from UB for male dogs where information on the cause of death was available was 0.41. Neutered dogs had 1.94x the odds of death due to a UB compared with entire dogs. Aggression was the most prevalent UB overall. Veterinarians had recommended referral in 10.3% of cases where dogs died due to exhibiting a UB and had dispensed nutraceutical, pheromone or pharmacological treatment to 3.0% of the UB cases that died. This study shows that undesirable behaviours require better preventive measures and treatment, through further research and education of veterinarians, other professionals within the dog industry and owners.

The Welfare of Farmed Animals (England) Regulations (2007) make it an offence to allow unnecessary suffering to animals, highlighting that farmers have a duty of care for their livestock. Despite this, the current global mean prevalence of lameness in sheep in England is 5%; ie ~750,000 lame adult sheep at any time. To investigate farmers’ attitudes to sanctions and rewards as drivers to reduce the prevalence of lameness in sheep, farmers’ attitudes to external inspections, acceptable prevalence of lameness and attitudes on outcomes from inspections were investigated using a self-administered questionnaire. A total of 43/102 convenience-selected English sheep farmers responded to the questionnaire. Their median flock size was 500 ewes with a geometric mean prevalence of lameness of 2.8%. Few farmers selected correct descriptions of the legislation for treatment and transport of lame sheep. Participants considered 5-7.5% prevalence of lameness acceptable and were least tolerant of farmers who rarely treated lameness and most tolerant of farmers experiencing an incident out of their control, eg disease outbreak. Participants consider sanctions and rewards would help to control lameness on sheep farms in England. Sanctions (prosecution, reduction in payment from the single [basic] payment scheme or suspension from a farm assurance scheme) were considered ‘fair’ when lameness was ≥ 10% and rewards ‘fair’ when lameness was ≤ 2%. If these farmers’ attitudes are applied to 1,300 randomly selected flocks with a mean prevalence of lameness of 3.5%, 24.6% of flocks that had ≥ 10% lameness would be sanctioned and 32.5% of flocks that had ≤ 2% lameness would be rewarded.

The Welfare Quality® (WQ) protocol for on-farm dairy cattle welfare assessment describes 33 measures and a step-wise method to integrate the outcomes into 12 criteria scores, grouped into four principle scores and into an overall welfare categorisation with four possible levels. The relative contribution of various welfare measures to the integrated scores has been contested. Using a European dataset (491 herds), we investigated: i) variation in sensitivity of integrated outcomes to extremely low and high values of measures, criteria and principles by replacing each actual value with minimum and maximum observed and theoretically possible values; and ii) the reasons for this variation in sensitivity. As intended by the WQ consortium, the sensitivity of integrated scores depends on: i) the observed value of the specific measures/criteria; ii) whether the change was positive/negative; and iii) the relative weight attributed to the measures. Additionally, two unintended factors of considerable influence appear to be side-effects of the complexity of the integration method. Namely: i) the number of measures integrated into criteria and principle scores; and ii) the aggregation method of the measures. Therefore, resource-based measures related to drinkers (which have been criticised with respect to their validity to assess absence of prolonged thirst), have a much larger influence on integrated scores than health-related measures such as ‘mortality rate’ and ‘lameness score’. Hence, the integration method of the WQ protocol for dairy cattle should be revised to ensure that the relative contribution of the various welfare measures to the integrated scores more accurately reflect their relevance for dairy cattle welfare.

This study aimed to refine bird-soiling as a broiler chicken (Gallus gallus domesticus) welfare indicator, and to develop and test two additional indicators, namely contact dermatitis on the breast and abdominal areas and carcase scratches. We constructed a questionnaire with pictures of birds presenting different indicator levels for classification as absent, low, moderate or severe. The questionnaire was sent to 146 invited experts for the first round and 88 for the second, in a Delphi process. Visual scales were built for the target indicators, which were tested by three assessors in ten flocks on-farm (n = 1,303 birds) and at the slaughterhouse (n = 1,631 birds). High concordance was observed among groups of Delphi respondents and among assessors. A total of 90.7% of the birds were either moderately or severely soiled, 99.9% were poorly feathered, 73.4 and 90.0% presented erythaema and carcase scratches, respectively. The correlations between litter quality and all outcomes assessed on-farm, and between bird-soiling and contact dermatitis on the breast and abdominal areas, were moderate. Results suggest that adoption of the proposed scales may improve our ability to assess broiler chicken welfare, since relevant problems were prevalent and measurement consistency acceptable. Substantial concordance observed among assessors encourages application of these animal-based indicators to assess broiler chicken welfare in a wide range of poultry houses, in a variety of different countries, thereby allowing the scales to be tested in a host of animal welfare conditions.

Welfare considerations surrounding dog (Canis familiaris) breeding practices are contentious in some sectors of the community. However, public perceptions surrounding dog breeding practices are poorly understood. The aims of this study were to describe perceptions of dog breeding and associated welfare concerns held by members of the general public and identify whether factors exist that potentially predict these perceptions. Australian residents (n = 986) completed an online questionnaire investigating their perceptions of, and attitudes towards, companion dog breeding and other acquisition methods. Participants predominantly indicated that breeding dog welfare was important, that dog breeding should be regulated, and that tougher laws are necessary to improve breeding dog welfare. Furthermore, three groups of respondents were identified: those who supported breeder-sourced companion dogs but felt that current regulations were inadequate to ensure satisfactory welfare, those who disapproved of dog breeding and felt adoption was the only appropriate acquisition method, and those who felt breeding was acceptable and that current industry practices provide adequate welfare. Several participant factors predicted cluster membership, including age, characteristics considered important when acquiring a companion dog, the source of their most recent dog, and their dog breeding knowledge and/or experience. This study provides a direct preliminary examination of public perceptions of dog breeding, breeding practices, and associated welfare concerns, and the factors associated with these perceptions. This information can be used to guide those who provide companion dogs to the public and inform evidence-based policy development concerning companion dog breeding and acquisition.

The aim of this study was to broaden the understanding of Finnish cattle and pig farmers’ perceptions of the on-site animal welfare inspections carried out by official authorities in livestock farms. The study was conducted using an electronic questionnaire, aimed at 500 Finnish cattle and 500 pig farmers. Responses were received from 96 cattle farmers and 105 pig farmers, of which 20 and 55, respectively, had undergone an animal welfare inspection. It was found that most of the farmers recognised the need for animal welfare inspections, but also that a more negative attitude was prevalent among farmers who had undergone these inspections. The inspection itself was a far more negative experience if the farmer had not understood the reason for the inspection, no opportunity existed to be heard, or the findings of the report were found to be unclear. The results suggest that although the farmers generally approve of inspections, their own negative experiences affect their perceptions. Moving forward, efforts should be made by inspectors to enhance the level of communication, thereby ensuring the findings of the report are clear to the farmer.

Given the difficulties of conducting regular endocrine and veterinary assessments of animals, behavioural observations are often the most commonly used tool to assess the welfare of animals in human care. Behavioural measures, inexpensive and convenient to collect, also have their challenges, such as ensuring the behaviours of interest are reliable indicators of an animal's internal state. Welfare assessments include both positive and negative indicators, and a commonly used indicator of negative welfare is self-directed behaviour (SDB). SDB has been described as a behavioural indicator of stress through observation and experimentation; however, this pattern is not universal despite assumptions otherwise. The purpose of this study was to experimentally evaluate the use of SDB as an indicator of negative welfare in mandrills (Mandrillus sphinx) with the goal of understanding the function of SDB in relation to stress. Using a touchscreen-mediated cognitive task, the mandrills were observed to self-scratch significantly more often during incorrect than correct trials; however, rates of SDB did not vary between increasingly difficult testing conditions. The mandrills had individual variation in their use of body-shakes and yawns under negative and positive conditions that mirror similar variation observed in other primates. This study provides experimental evidence that self-scratching in mandrills can be used as a behavioural indicator of anxiety and that welfare assessments for animals in human care need to account not only for species’ differences, but also for individual differences.

There has been an increased demand by some sections of society for higher farm animal welfare standards. In response, a number of programmes marketing products of animal origin, produced under higher animal welfare standards, have been established on the market in recent years. However, the market segments for products from so-called animal welfare programmes (AWPs) have remained small. Farmers are considered an important stakeholder group for higher market shares of more animal welfare-friendly products. Farmers’ decision to adapt their production to the requirements of AWPs is multi-dimensional, but always linked to financial incentives. Since little is known about the financial attractiveness of higher animal welfare standards in livestock farming, this study investigates the perceived economic success of 579 conventional farmers keeping livestock on their farms. The survey data were analysed using propensity score matching to assess the average effect of participation in AWPs on a farm's perceived profitability, liquidity and stability from the farmer's point of view. No significant effect was found of participation in AWPs on the economic success of farmers. The implications of this result are two-fold. On the one hand, it suggests that it is of particular importance to create further financial incentives to encourage farmers to take part in these programmes. On the other, it shows that farmers’ concerns that the required costly and highly specific investments will pay off are unfounded, as farmers participating in AWPs rate their own financial situation as equivalent to that of their colleagues not participating in AWPs.

The housing condition of pig (Sus scrofa) fattening farms are increasingly receiving criticism, because they are associated with impaired animal welfare. Consumers view the increase in farm sizes critically, even though scientifically based knowledge on the relationship between farm size and welfare is still limited. Therefore, the aim of this study was to assess the welfare level of conventional fattening pig farms in Germany and to evaluate the relationship between farm size and animal welfare level. In total, the Welfare Quality® protocol (WQ) for pigs was applied on 60 farms. Farms were classified according to their size into small (< 1,500 pigs per farm), medium (1,500-3,000 pigs per farm) and large (> 3,000 pigs per farm). Independent of the farm size, the overall WQ classifications ‘excellent’ and ‘not classified’ were not recorded in any of the farms, while ‘enhanced’ and ‘acceptable’ was achieved by 80 and 20% of the farms, respectively. Farm sizes had no effect on any of the four principles ‘good feeding’, ‘good housing’, ‘good health’ or ‘appropriate behaviour’. Overall, moderate bursitis (35%) was found to be the most prevalent indicator of welfare-related problems. However, it did not differ between farm sizes. Another highly prevalent indicator, moderately soiled body, increased from 11.1% in small-to 20.8% in large-sized farms. In conclusion, our findings show that none of the farm sizes were superior in terms of animal welfare. Overall, acceptable or enhanced scores were achieved for many of the criteria, however the need for improvement in other criteria such as ‘expression of other behaviour’ and ‘positive emotional state’, was clear.

Gestation stall housing for pregnant sows (Sus scrofa) has been, or is being, phased out in many parts of the world in response to public criticism. However, in Brazil, one of the largest global producers and exporters of pork, gestation stall housing is still common. The objective of this study was to explore the views of Brazilians, including participants associated (ALP) or not with livestock production (NotALP), on gestation stall housing. Participants were provided the option of accessing a short text describing the housing system and a video of pregnant sows housed in either individual or group housing. Participants (ALP; n = 176, NotALP; n = 173) were asked to state their position on housing pregnant sows in individual stalls and to provide the reason(s) justifying their position. More NotALP (87%) participants than ALP (69%) participants rejected individual stalls. More participants (85%) that accessed the optional information rejected the stalls than those (71%) that did not. Qualitative analyses revealed that animal welfare, most often in reference to animal sentience, freedom of movement and ethics, was the main justification given for rejecting gestation stalls. Those in favour of individual stalls justified their position with statements such as improved production, handling and animal health, and reduced aggression. This qualitative, exploratory study, based on a convenience sample of participants, does not represent the views of Brazilian society; however, it identified some shared values between participants associated with livestock production and those that are not. Our findings highlight that opposition to gestation stalls for sows reflects an ethical position regarding the treatment of livestock and should not be interpreted as support for group housing in confined systems.

Following a period of consultation in 2017, the Department for Environment, Food and Rural Affairs (Defra) has recently published an updated Code of Practice for the Welfare of Meat Chickens and Meat Breeding Chickens in England. The Code came into force in March 2018.

There are approximately 8.5 million dogs, 8 million cats and 1 million horses in the United Kingdom. According to the Animal Welfare Act 2006 (Section 9), any person responsible for an animal is required to take all reasonable steps to meet the needs of that animal. Under the Act, the needs of an animal are based on the ‘Five Freedoms’ and are considered to be:
