Rabbits (Oryctolagus cuniculus) are popular companion animals, yet there has been little research into rabbits kept as pets in Sweden. Many rabbits that are rehomed are done so via personal contacts rather than through animal shelters. The purpose of this study was to provide a picture as to why rabbit owners rehome their pets and to what extent this is done in Sweden. There were 505 rabbits put up for rehoming through a large Swedish advertisement site during the winter of 2012/2013. The most commonly stated reasons for trying to rehome rabbits were ‘Lack of time’ (35.8%), ‘Owners are moving’ (16.6%) and ‘Allergies’ (13.2%). The mean age of the rabbits was 17.6 months and most rabbits were put up for sale for a price of between €11.1 and €55. Requests about the new home were mentioned in 46.8% of the adverts and the majority of the comments described the type of home needed for the rabbit. Reasons for relinquishing rabbits were similar to those found in other studies and the number of rabbits with behavioural problems was very low (0.9%). We conclude that a number of rabbits in Sweden are experiencing rehoming and the effect of this on their welfare should be further investigated.

Primates are highly social animals and appropriate enrichment is required to ensure their psychological well-being. Mirrors are sometimes used as social or sensory environmental enrichment. In this paper we investigate the suitability of mirrors as enrichment for captive primates, by reviewing the literature on mirror implementation in captive primate environments. Mirror-directed responses are mainly social as the mirror self-image is often seen as a conspecific. Although positive exploration and affiliative behaviours are observed, negative aggressive behaviours towards the mirror are most frequently recorded, and abnormal behaviours in primates do not decrease in mirror-enriched environments. There appear to be differences in habituation rates to mirrors amongst primates. While habituation to enrichment is generally perceived to be undesirable, this criterion should not apply when mirrors elicit negative behaviours. Primates that show mirror self-recognition, which are mostly great apes, may be best suitable for mirror enrichment, as they do not perceive the mirror self-image as a threatening conspecific. Increasing the understanding of the reflective properties of a mirror might help primates to understand that the image in the mirror is not real. This could be attained by using small, mobile mirrors. We suggest that mirrors can make decent primate enrichment if the primate understands its reflective properties, which should be evaluated on an individual level. Appropriate use of mirrors as sensory enrichment can improve primate well-being and prevent suffering.

Injurious feather-pecking in non-cage systems is a serious economic and welfare concern for the egg-producing industry. This study presents results from data of over 1,000 flocks from producers who supplied free-range eggs to McDonald's Restaurants Ltd UK between 2008 and 2013. These producers had a minimum 5% of the outdoor range planted in trees. We investigated the correlation between the plumage damage of end-of-lay hens with i) proportion of the total range planted with trees and ii) proportion of canopy cover within tree-planted areas. As tree canopy developed over the study period, we also investigated whether there were any changes in end-of-lay plumage-damage scores within farms, with year over the five years. There was a negative correlation between canopy cover and plumage damage at the end of lay, ie less canopy cover within tree-planted areas resulted in significantly worse plumage damage at the end of lay. There was no correlation between the amount of range planted and plumage damage at the end of lay. These results support the notion that it is the degree of shade and shelter (ie quality of cover) that is important to the hens rather than the absolute area. We did not find any association between year and end-of-lay plumage-damage scores. Due to commercial changes in supply, the proportion of farms providing data for ≥ 3 years was small, thereby limiting the data set with which to compare individual farms’ plumage-damage scores. It is hoped the relationship between year and plumage-damage score will be reexamined in a future study.

While the international zoological community is committed to enhancing the welfare of individual animals, researchers have yet to take full advantage of the tools available for non-invasively tracking behavioural and physiological indicators of welfare. We review technology currently being applied in studies of zoo, farm and laboratory animals to regularly monitor welfare status, as well as to evaluate responses to particular stimuli and situations. In terms of behavioural measures, we focus on automated assessments that offer insight into how animals — even those that are nocturnal or elusive — behave when humans are not present. Specifically, we provide an overview of how animal-attached technology (accelerometers, global positioning systems, radio frequency identification systems) can be implemented to generate activity budgets, examine use of space, conduct gait assessments, determine rates of movement and study social dynamics. We also emphasise the value of bioacoustics, as the rate and acoustic structure of certain vocalisations may vary across contexts and reflect an animal's internal state. While it can be challenging to identify non-invasive methods for investigating physiological welfare indicators, we discuss approaches (thermography, tracking measures of heart rate) that may be especially useful for monitoring affective states and psychophysiological functioning. Finally, we make a concerted effort to highlight tools that allow welfare scientists to consider measures of positive welfare. Ultimately, zoos can ensure that each animal has the opportunity to thrive by employing technology to create baseline behavioural and physiological profiles, conduct ongoing monitoring schemes and assess responses to specific conditions, events and stimuli.

Farrowing is an important period in pig production, with sow health and piglet mortality representing a welfare issue and an economic loss. Sow health and welfare is critical for piglet survival and good management can improve welfare and productivity. This study investigated the management of sows around farrowing and attitudes of UK pig farmers towards sow pain and difficulty farrowing. Farmers were asked how often they provided night checks, used farrowing induction and administered pharmaceutical products during and after farrowing. Farmers and veterinarians were asked if they used or prescribed anti-inflammatories for farrowing-related health issues. Farmers were asked if pain at farrowing was a problem for gilts and sows and what percentage they considered to have difficulty farrowing. Convenience sampling using a number of distribution methods was used. Sixty-one farmers and 52 veterinarians responded. Of the farmer respondents, ten worked on outdoor and 51 on indoor farms. Night checks were reported as frequently provided and farrowing induction was rare. Many respondents reported using oxytocin substitutes at least sometimes during (74%) or after (54%) farrowing. Azaperone was reported to be used at least sometimes by 45% of respondents during and 33% after farrowing. Farmers indicated that pain at farrowing was more often a problem for gilts than sows and 5% of gilts and 4% of sows were considered to have farrowing difficulty. The high level of supervision around farrowing, with the use of night checks, is encouraging and could improve welfare. Frequent use of oxytocin substitutes, which promote farrowing and milk let-down may negatively impact sow and piglet welfare and could be masking poor mothers that fail to perform well without intervention. This study provides interesting information regarding the management of sows around farrowing, which could inform future research and education to improve sow and piglet welfare in the periparturient period.

Until now, only a limited amount of research has been carried out on addressing attitudes towards sport horse welfare (AHW). In order to contribute to filling this gap, the goals of this study were two-fold: the investigation of the influence of different demographic factors and factors related to equestrianism on the AHW and the demonstration of the applicability of Partial Least Squares Equation Modelling (PLS) in this field of research. An online survey was conducted among 2,947 equestrians. A research model was established based on eleven factors, which were investigated for their potential influence on the AHW and their relationships to each other. This model was analysed by means of PLS which, to the best of our knowledge, has not been used before to investigate human attitudes towards horses (Equus caballus). The results show that the factors with the highest impacts on the AHW were the affection for animals, the attitude towards classically organised equestrianism and the utility orientation. Gender, income, agricultural background, tradition, brand orientation and the importance of breed and pedigree were also found to exert a significant influence on the AHW. In contrast, age and involvement in horse-riding as a hobby were found to have no effect on the AHW. Furthermore, several significant relationships could be identified among the different factors. In conclusion, the present study provides an insight into the factors influencing the complex AHW and demonstrates the applicability of the PLS for research in this field.

The success of breeding primates in captivity has led to a surplus number of animals in collections. This review examines published journals and key books to investigate the various methods of primate population control. Hormonal, surgical and separation methods are discussed and evaluated with regards to behavioural and welfare implications. Methods of dealing with surplus animals are also reviewed. It is concluded that the successes of contraception methods vary significantly between species, and in some cases not enough is known to conclusively state that one method is preferable to another. The behavioural effects of contraception should be evaluated, as social status and sexual behaviours can be negatively affected by contraception. Non-reversible sterilisation methods, such as castration, should not be used without thorough evaluation due to the behavioural effects on the individual and group as a whole. Overall, the zoo community should share information of successes and failures of contraception in different species, and professional advice should be sought to ensure that the welfare of primates in captivity is not compromised.

Ear posture, or the frequency of postural changes, may reflect various emotional states of animals. In adult sheep (Ovis aries), the ‘forward’ ear posture has been associated with negative experiences whereas the ‘plane’ posture has been associated with positive ones. This study aimed to see whether ear postures related to the experience of pain in lambs. The ear behaviour of four to eight week-old lambs (n = 44) was measured before and after tail-docking using a rubber ring. Each lamb was docked and its behaviour recorded while in the company of an observer lamb of similar age; each acted once as focal (docked) lamb and once as observer within the same pair. Lambs were docked in one of two rounds, so that half were docked in their first exposure to the test environment and half in their second exposure. Tail-docking was associated with an increase in the proportion of time spent with ears backward and decreases in the proportion of time spent with ears plane and forward (mean [± SEM]: Backward: pre 0.12 [± 0.04], post 0.56 [± 0.04]; Plane: pre 0.55 [± 0.05], post 0.19 [± 0.05]; Forward: pre 0.27 [± 0.04], post 0.18 [± 0.04]). There was also a significant increase in the number of changes between ear postures after docking (pre 5.63 [± 0.66], post 9.11 [± 0.66]). Over both periods, female lambs held their ears asymmetrically for longer than males (mean of ranks [± SEM] [raw proportion of time]: Females 52.14 [± 3.44] [0.09 (± 0.01)], males 37.54 [± 3.40] [0.05 (± 0.01)]). This is the first study to demonstrate changes in the ear posture of lambs associated with the negative experience of pain. Ear posture is a non-invasive indicator of physical pain in lambs and may be useful for evaluating potential welfare compromise.

The social sciences can help provide a deeper understanding of human-farm animal relations. However, social science research exploring problematic human-farm animal interactions can be of a sensitive nature. Studies that carry risks for participants and the researcher are known methodologically as sensitive research. However, there is little discussion in the animal welfare sciences on how best to conduct research of this nature on animal owners, despite recommendations being made for more interdisciplinary collaboration between the animal welfare sciences and social sciences. Drawing on social science research conducted in 2012 on the human element of on-farm animal welfare incidents in the Republic of Ireland, this short communication presents a case study of the sensitivities and challenges involved in carrying out social science research related to farm animal welfare. This communication details the steps involved in recruiting participants, the methodological challenges encountered, and the approaches used to overcome these challenges. Our experience suggests that when conducting socially sensitive research, careful consideration needs to be applied to the recruitment process, and the study design must aim to minimise the potential risks for all involved. Professionals in the field, such as veterinarians, can play an important role in outlining some of the implications involved, and in overcoming research challenges. Understanding the challenges to this form of research will help to maximise research potential.

This survey was undertaken to assess the attitudes of Croatian veterinary students regarding farm animal welfare issues. The study included students of all undergraduate years at the only Faculty of Veterinary Medicine in Croatia. First-year students were surveyed twice, ie before and after attending the course on animal welfare, using a written questionnaire containing statements with a five-point Likert scale for choice of answers. Students consider good animal welfare necessary for sustainability of farming systems and food quality and safety, ranking particular issues in the following order, biological functioning > natural living > emotional states. Students also believe that cattle and pigs have greater cognitive abilities and that their welfare is less compromised in comparison with poultry, whereas standard management procedures performed in pig production are perceived as more humane than beak-trimming in poultry. In addtion, students tend to consider pain in farm animals caused by management procedures only when these procedures involved the affliction of significant pain. There were no differences between attitude scores on most of the statements from first-year students before and after the course. Furthermore, for the majority of statements, the mean responses were lower in final-year students, suggesting a lower level of empathy toward farm animals. Although similar results have also been recorded elsewhere in the world, these results raise concerns as to the ability of these future veterinarians to promote good farm animal welfare in the country and abroad. The results also suggest a need to modify veterinary student education in Croatia in the field of farm animal welfare.

Fish welfare is a key factor in ensuring successful cultures. Farmed fish that are stressed have been shown to be susceptible to pathologies and present lower growth rates. The present work seeks to check the efficacy of faecal cortisol as a non-invasive method of assessing acute stress in a commercial cultured fish, the gilthead seabream (Sparus aurata). Typical stress markers (plasma cortisol, glucose and lactate) and faecal cortisol were measured in basal and post-stress (air exposure) state. Plasma and faecal cortisol, and plasma lactate after acute stress varied significantly compared to basal levels. Moreover, faecal cortisol showed a significant correlation with plasma cortisol and lactate. In conclusion, this work describes an easy, non-invasive and practical technique to assess acute stress in farmed fish. Further studies are needed to focus on other practical procedures for chronic stress measurements in sea-farms in order to improve the welfare of these animals.

Keel-bone damage and foot injuries have a negative impact on welfare in laying hens. The extent of the problems in Danish commercial flocks of layers is unknown. Therefore, the aim of this study was to assess the current prevalence of keel-bone damage and foot injuries in Danish commercial flocks of laying hens and to investigate the effects of production system, housing system, hybrid and age. The occurrences of keel-bone damage, hyperkeratosis and missing toes were higher at 62 compared to 32 weeks of age, while the reverse was found for toe wounds, foot-pad lesions and bumble feet. There was no difference between barn and organic production systems in the risk of having keel-bone fractures and foot injuries, except that barn hens were more likely to have foot-pad lesions than organic hens (32 weeks: 16.1 vs 3.1%). Hens in multi-tiered systems were more likely to have keel-bone fractures compared to hens in single-tiered systems (62 weeks: 11.6 vs 4.9%). Of the four hybrids, Lohmann Brown Lite had a higher risk of keel-bone fractures, whereas bumble feet were found more frequently in Lohmann LSL Keel-bone damage and foot injuries are less common in Danish non-cage systems compared to most of the reporting presently available from other countries. We suggest transnational studies, aimed at identifying the causal factors of this discrepancy, to increase existing knowledge on how to reduce incidences of keel-bone damage and foot injuries.

The ability to monitor the welfare of animal collections in zoological institutions is critical to the mission of these facilities. Historically, zoos have utilised negative indicators of welfare, such as stereotypic behaviour to examine and monitor collection animals. However, absence of stereotypic behaviour or negative indicators of welfare does not indicate that an animal is thriving. The goal of the current study was to continue efforts to validate behavioural diversity as an indicator of welfare using cheetah (Acinonyx jubatus) as a model species. Behavioural and faecal glucocorticoid metabolite data were collected on 18 cheetah at the San Diego Zoo Safari Park over a period of three months to explore the relationship between behavioural diversity and adrenal hormones related to the stress response. Results suggest that behavioural diversity can be utilised as an indicator of animal welfare to monitor animal collections within zoological facilities. However, additional research with other species should be conducted to better understand behavioural diversity as a positive indicator of animal welfare. We hope this manuscript will increase discussion surrounding behavioural diversity as well as increase efforts to validate it as an indicator of welfare.

Understanding human-animal interactions in livestock production systems is crucial for improving animal welfare. It is therefore of general interest to investigate how livestock animals obtain information from humans. By using an object-choice paradigm, we investigated whether domestic pigs (Sus scrofa) (n = 4) were able to use a variety of human-given cues, such as different pointing gestures, to find a hidden food reward. In Experiment 1, an experimenter pointed towards a baited location in front of the pig while the extent of the protrusion of his hand from the upper body was varied. Pigs had problems using pointing gestures that did not protrude from the upper body of the experimenter, but were able to successfully use a long cross pointing administered with the contralateral hand of an experimenter to find a hidden reward. In Experiment 2, an experimenter indicated a baited location that was behind the pig using either a pointing gesture, his body or his head orientation. All four individuals used the pointing gesture and one pig was able to use the head orientation to find the hidden reward. The results provide additional evidence of pigs’ ability to use novel human-given cues as well as on the limits of their abilities, and will contribute to a better understanding of pigs’ perception of their stockpersons and handlers.

Farmers’ recognition of health and welfare problems, and their responses to related intervention programmes, such as those to reduce injurious pecking in hens, directly influence the welfare of animals in their care. Changing those responses can be achieved through a re-positioning of social drivers as well as from individual behaviour. This study begins by considering how certain levels of plumage damage become normalised while others might be considered unacceptable. Drawing upon in-depth farmer interviews, the study investigates how management practices for addressing the issue of injurious pecking are developed and enacted, looking at the relative influence of intrinsic and extrinsic individual behavioural factors. Twelve farmers with varied uptake of evidence-based management strategies designed to reduce levels of injurious pecking were interviewed. Although farmers ranked images of flocks with various levels of plumage damage in a similar order to scientists, their perception of levels of injurious pecking in their own flocks varied, and was not consistently associated with the actual levels measured. Most farmers recognised both financial and welfare implications of injurious pecking and expressed pride in having a good-looking flock. The popular management strategies were those designed to redirect pecking to other objects, whereas a substantial barrier to uptake was the perception of creating other problems: for example, mislaid eggs if early access to litter and range were adopted. To achieve uptake of knowledge that improves animal welfare on-farm, it may be necessary both to shift the norms perceived as acceptable, and to overcome barriers to change that include lack of time and understanding, by providing impartial advice and facilitation of ownership of the issues.

Pain is an indicator of welfare status in livestock, and attitudes play a key role in the assessment and treatment of pain in animals. Veterinarians’ and dairy producers’ perceptions of cattle pain are affected by gender, age and work experience. The aim of this paper was to study beef producers’ attitudes regarding disbudding as well as the painfulness of certain cattle diseases. A questionnaire was sent out to 1,000 Finnish beef producers and the response rate was 44%, representing 19% of all Finnish beef producers. Producers graded their attitudes on a five-point Likert scale and perception about pain on an eleven-point numerical scale. Factor analysis was used and four factors were established. These factors described producers’ assessment of disbudding-related pain, their sensitivity to pain in cattle, their willingness to self-medicate disbudded calves and their perceived importance of horns. Factor scores were tested for differences between genders and the use of disbudding on farms with Mann Whitney U-tests. Kruskal-Wallis tests were used to assess differences among producers’ age, work experience and herd size. Female beef producers assessed animal pain higher than male beef producers. Older and more experienced beef producers showed more positive attitudes towards cattle with horns than younger or less-experienced ones. Older beef producers were more sensitive to cattle pain than younger producers and beef producers with a smaller herd size took disbudding pain more seriously and were more sensitive to cattle pain than the producers with larger herds. Producers who did not use disbudding valued horns more than producers using disbudding.

This study reports novel information on the animal handling, management and human-animal interactions in Indonesian cattle abattoirs. The slaughter of 304 cattle was observed and there was a high percentage of re-stuns in all abattoirs (range: 8-18.9%) when compared to a variety of international auditing guidelines. The average stun-to-neck cut time was within international recommendations (average: 9 s; range: 4-15 s). Time spent in lairage varied between animals and facilities and was compliant with international guidelines. Handling times were extremely variable (2 s-23 min 40s), but were only weakly correlated with a variety of handler techniques including the total number of handler interactions (sum of visual, auditory and tactile interactions, suggesting that long handling time does not increase handler interactions. There was a moderate correlation between the subjective handling scale and most of the objective behaviours, indicating that this may be a useful way to summarise handler behaviour in future assessments. The current study provides novel information about animal welfare in Indonesian abattoirs and highlights that management practices at the four abattoirs generally comply with international standards. The results also suggest that the subjective handling scale was moderately associated with the frequency of handler interactions, and so may be a useful measure of handler behaviour.

The aim of this study was to assess smallholder farmer awareness in terms of good pig management and to identify serious management issues that should be readily changeable despite resources being limited in a rural setting. Methodology was a combination of questionnaire and observational surveys performed at pig-keeping households practising either confinement or a free-range system. Households were identified using the snowball method. A total of 120 pig-keeping households were included, of which 32 practised free-range systems and 88 confined their pigs. The observational survey included management practices and welfare assessment based on one pig from each of the 120 households. The results indicated that farmers were not aware of the basic requirements of pigs regardless of the production system practised. Water was often neglected and provided less frequently among those practising free-range. Pigs kept free-range also received treatment less frequently compared to those kept confined. Pigs were generally kept in poor conditions with risk of injury and without shelter from wind, rain, cold, heat, and sun. Welfare issues exist within both production systems, but issues within the confinement system could be easily eliminated with proper management. More knowledge on basic pig husbandry is required in the region and is essential for improving production. Educating farmers on the basic requirements for water and feed, alone, could vastly improve smallholder pig production. Education on pig management should therefore be a cornerstone in any research activity involving smallholder farmers in rural areas.

The maintenance of head-only minimum stunning currents for sheep to ≥ 1.0 Amp as per current legislation was examined in two trials in a commercial abattoir. In the first trial, a Jetco MS100 stunner failed to maintain the current to > 1.0 Amp in 118 of the 228 sheep. In a second trial, a Jetco MS105 delivered sufficient current in all sheep (n = 275) to meet the legislative requirement, apart from a single animal. Recorded electrocardiograms showed a regular heartbeat, with no evidence of ventricular fibrillation, in all animals in both trials following stunning and neck-cut. Only one of the two stun units may therefore be considered to meet the statutory requirements but both may meet the requirements for halal slaughter where pre-stun is considered acceptable.

When female kangaroos are shot during commercial harvesting, it is a requirement that dependent young-at-foot are euthanased. However, there are anecdotal reports that harvesters either cannot euthanase young-at-foot (eg they do not see them or they flee) or will not (eg they do not think it is necessary). In this study we used the theory of planned behaviour to understand the beliefs, attitudes and behaviour of kangaroo harvesters with regards to the euthanasia of young-at-foot. We firstly conducted a survey of a small number of kangaroo harvesters (n = 21) to gather information to develop the main questionnaire. Recruitment of participants was conducted using a number of approaches including a mail out of over 600 pen-and-paper questionnaires to harvesters in NSW, QLD and SA, Australia. We received completed questionnaires from 65 harvesters. Behaviour was directly observed in only 14 harvesters. The results indicated that those kangaroo harvesters with a more favourable attitude towards euthanasing young-at-foot and who feel more social pressure to do so are more likely to intend to euthanase young-at-foot. However, intention to euthanase orphaned young-at-foot only rarely translated into actual behaviour. The participating harvesters believe that euthanasing young-at-foot reduces joey suffering; that government kangaroo management agencies and farmers and graziers approve of them doing it (but animal protection groups do not); and that the greatest limiting factor preventing them from euthanasing young at-foot is that they escape. This research revealed deficiencies in knowledge and training of kangaroo harvesters with regard to humane harvesting practices. We conclude that the use of social psychology methodology and frameworks, such as the theory of planned behaviour, can provide a detailed insight into human attitudes and behaviours that affect animal welfare. This approach can reveal the most important specific factors to consider when training and educating personnel who have direct responsibility for the humane treatment of animals.
