There is widespread transport of reptiles for the pet trade throughout the world and the ‘dead on arrival’ rates are high. The eastern blue tongued (EBT) lizard (Tiliqua scincoides; Order: Squamata; suborder: Lacertilia) is particularly popular due to its unusual blue tongue. Noise, vibration and thermal discomfort are known contributors to transport stress. We analysed the behaviour of EBT lizards (n = 9) when exposed to four of these stimuli in a changeover design. Lizards were exposed to Heat (35°C), Cold (15°C), high or low frequency noise or a Control treatment with no stimulus in a test chamber for a 5-s period. Heating blankets and ice packs were used to create the hot and cold temperature stimuli in the test chamber, and a speaker broadcast noise/vibration from a truck recording. The test chamber was connected to an escape chamber, accessible after exposure to the stimulus, and a small hiding chamber opposite the test chamber. Lizard behaviour was monitored during stimulus exposure and then for a further 15 min, after which each lizard was removed. Lizards exposed to Cold spent less time in the test chamber (330 vs 434 s) and more time inactive in the escape chamber (148 vs 40 s). They also spent longer walking towards the hiding chamber (18.0 vs 10.5 s) and walking in the hiding chamber away from the stimulus (3.6 vs 2.3 s). We conclude that cold temperatures are potentially noxious for lizards in a simulated transport environment as they reduce activity and increase escape attempts.

Legislation governing non-stun slaughter of sheep in England requires that they are individually and mechanically restrained for slaughter and not moved for at least 20 s post neck cut, until unconsciousness or insensibility occurs. Complying with the need for individual handling, in what is a flock animal, has the potential to adversely affect welfare, in turn contravening the general legislative requirement to reduce any avoidable distress at slaughter. This study investigated the effects of individually loading and restraining lambs compared with the normal practice of group loading and restraint of lambs prior to slaughter when using a V-shaped restrainer. Rotating and static design loading pens were also compared to represent the range of conditions and facilities found across English abattoirs. Plasma cortisol and lactate concentrations were significantly lower in group-loaded animals and significant reductions were observed in the time duration of a range of components of handling as well as the average total time to load each lamb. Loading pen type had a less marked impact upon results, however, individual loading and restraint of lambs within a V-shaped restrainer appears particularly stressful for sheep in comparison with group loading. The loading pen type had a mixed effect although the rotating crowding pen is likely to have minimised physical exertion in lambs during loading and restraint. Based on these findings, group loading in a V-shaped restrainer, whilst complying with the 20-s standstill, is likely to be preferable in religious, non-stun slaughter of sheep.

The welfare of laboratory rats and mice is sought to be optimised through adjustment of a variety of environmental factors, including light intensity and photoperiodicity. However, the fact that rodents are able to perceive ultraviolet (UV) light tends to be ignored. The importance of being able — as a rodent — to utilise this part of the visual spectrum has not been studied in great detail, but suggestions, based on the evolutionary success of this trait, indicate that the deprivation of ultraviolet light in mice and rats could perhaps impact negatively on the welfare of these animals. Further research into the importance of having a UV light source available to rats and mice should be encouraged.

Separation anxiety (SA) is one of the most common canine behaviour problems and can have serious negative effects on dog welfare. Treatment of SA may include changing the environment around the dog, pharmacological treatment and behavioural therapy. The latter is considered the most important part of the treatment and is intended to habituate the dog to being alone and to reduce its dependence on the owner. The objective of this paper is to discuss two aspects of the treatment of SA that may be in contradiction with our current understanding of the stress response. Advice commonly given to owners of dogs with SA includes giving false departure cues to prevent the dog from anticipating the actual departure. Instead, we recommend increasing the predictability of the owner's departure by maintaining the cues that signal it. Animals suffering from anxiety disorders are likely to develop contextual fear, ie to be frightened by merely being exposed to the same location where they have experienced an aversive event. As a consequence, we suggest that whenever possible, fake departures done as part of the habituation exercises to being left are done in a place different from that where the dog is actually left alone.

Given the increased interest in animal emotional reactions for assessing welfare, indicators for such reactions are sought. Ear postures and movements have been found to be promising indicators of emotional states in sheep and other animals. The manual recording of ear postures, however, is very time consuming and possibly prone to a degree of inaccuracy due to the subtle and fast nature of ear movements that have to be identified. Therefore, a number of previous studies have analysed the frequency of certain ear postures relative to all ear posture changes rather than measuring the relative duration spent with different ear postures. Here, we present an automated, continuous tracking system that keeps track of small and lightweight marker balls attached to the head and ears of sheep. We measured ear postures and movements when the animals were confronted with three physical stimuli thought to differ in valence (from negative to intermediate to positive). We then compared new ear-posture definitions reflecting the real time spent with certain ear postures during stimulation with previous definitions used for video-based analyses that assessed ear-posture changes in relation to the total number of observed ear postures. In the analysis, we correlated new and previous measures both between and within experimental stimuli using residuals from mixed-effects models. We found that the new and previous definitions of ear postures and movements correlated highly. Given these high correlations and the discussed theoretical and practical advantages of the automated tracking, the new recording system can be recommended highly for assessing reactions in animals that may indicate emotional states.

Expansion of the meat inspection process to incorporate animal-based welfare measurements could contribute towards significant improvements in pig (Sus scrofa domesticus) welfare and farm profitability. This study aimed to determine the prevalence of different welfare-related lesions on the carcase and their relationship with carcase condemnations (CC) and carcase weight (CW). The financial implications of losses associated with CC and CW reductions related to the welfare lesions were also estimated. Data on tail lesions, loin bruising and bursitis, CW and condemnation/trimming outcome (and associated weights) were collected for 3,537 slaughter pigs (mean [± SEM] carcase weight: 79.2 [± 8.82] kg). Overall, 72.5% of pigs had detectable tail lesions, whilst 16.0 and 44.0% were affected by severe loin bruising and hind limb bursitis, respectively. There were 2.5% of study carcases condemned and a further 3.3% were trimmed. The primary cause of CC was abscessation. While tail lesion severity did not increase the risk of abscessation, it was significantly associated with CC. Male pigs had a higher risk of tail lesions and of CC. The financial loss to producers associated with CC and trimmings was estimated at €1.10 per study pig. CW was reduced by up to 12 kg in cases of severe tail lesions. However, even mild lesions were associated with a significant reduction in CW of 1.2 kg. The value of the loss in potential CW associated with tail lesions was €0.59 per study pig. Combined with losses attributable to CC and trimmings this represented a loss of 43% of the profit margin per pig, at the time of the study, attributable to tail biting. These findings illustrate the magnitude of the impact of tail biting on pig welfare and on profitability of the pig industry. They also emphasise the potential contribution that the inclusion of welfare parameters at meat inspection could make to pig producers in informing herd health and welfare management plans.

Promotion of positive experiences in companion animals is essential for maximising good welfare. However, the dearth of published literature on the experience and expression of positive emotional states in companion dogs suggests they are less well understood than negative emotions. Owner knowledge can provide a basis for generating hypotheses for experimental research, and can inform education initiatives. An online survey of 445 dog (Canis familiaris) owners in the United Kingdom and the Republic of Ireland was used to identify key contexts and behaviours perceived by owners to be associated with positive emotions for companion dogs, and to examine factors which influence owner reports of key behaviours. The contexts most commonly associated with positive high arousal (PHA; ‘happy and excited’) were anticipation of walks or food and with positive low arousal (PLA; ‘happy and relaxed’) were resting and gentle stroking. Respondents’ behavioural profile for canine PHA involved barking, head held high, wide open and ‘bright’ eyes, ears pricked, tail wagging, mouth open, and active, playful behaviour. For PLA, respondents collectively described their dogs as silent, head resting, eyes closed or slightly closed, ears ‘down’, mouth closed and a calm/relaxed activity level. Notably, PLA states were described in less detail than PHA, suggesting the former may be less well understood or difficult to interpret. Dog breed and age, and owner experience and level of attachment to their pet significantly influenced respondents’ likelihood to report certain behavioural indicators, and may influence assessments of pet behaviour and underlying emotion. Further work is required to determine the validity of the behavioural expression and contexts perceived to be associated with positive experiences in dogs.

Many horses display unwanted behaviour prior to receiving concentrate feed or forage. These behaviours have received relatively little scientific attention as a distinct group of equine behaviour problems and risk factors for their performance have not been quantified. The objective of this study was to generate data on the diet of UK leisure horses, the feeding practices employed by their carers, and the prevalence of behaviour problems seen prior to feeding. A convenience sample of leisure horse carers were surveyed via a self-administered internet survey. Each carer provided data for only one horse, and to minimise recall bias was asked to report details of their horse's feeding routine over the week prior to completing the survey. Recruitment was spread over twelve calendar months. The survey was completed by 1,324 respondents, each reporting data for an individual horse in their care. Pre-feeding behaviour problems were common within the sample and were reduced by Principal Components Analysis into three components labelled: aggression; frustration; and stereotypies. While the specific risk factors associated with these problems differed, they fell into four distinct themes: how the horse is fed; the use of nutritional supplements; exercise and stabling; and the performance of oral investigative behaviour. The risk factors for pre-feeding behaviour problems identified in this study raise concerns about the way domestic horses are currently fed and managed. In conjunction with published empirical evidence they indicate that the welfare of domestic horses may be improved by adopting a feeding regime and management system more suited to their physiological and behavioural needs.

The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs (Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned to group sizes of one, two, four, or six pigs. Gas euthanasia of each piglet group was performed in a Euthanex® AgPro chamber. The chamber air was gradually displaced with CO2 gas over 5 min to establish an in-chamber concentration of approximately 80% CO2. Pigs remained in that atmosphere for an additional dwell period of at least 5 min. Higher stocking rates were associated with higher CO2 concentrations after gradual fill for both age groups. While there was no evidence of an effect of stocking rate on latencies to loss of posture or last movement in neonatal pigs, there was evidence of an effect on all measured efficacy variables in weaned pigs, with grouped pigs faster to succumb than solitary pigs. This finding is consistent with expected consequences of higher CO2 concentration at increased stocking densities. Aversive states and behaviours of focal pigs in the chamber were scored from video. Weaned solitary pigs displayed a high incidence of pacing and may have experienced isolation distress. Escape attempts were absent in neonates and not linearly affected by stocking rate in weaned pigs. Although the risk of hazardous interactions was correlated with group size, this study provided no evidence that isolation during gas euthanasia would benefit animal welfare.

The adaptability of horses and donkeys to different types of activity has seen the European equine industry become an important economic sector, giving rise to increasing concern regarding equine welfare. As part of the AWIN (Animal Welfare Indicators) project, this review focuses on scientific literature to find potential animal-based welfare indicators — the initial step in developing a valid, reliable and feasible on-farm welfare assessment protocol for equines. Forty-nine indicators were considered and classified in accordance with the four Principles and twelve Criteria developed by Welfare Quality®. Only practical indicators specifically for on-farm use were included, those requiring the use of specific instruments or laboratory analysis were excluded. Academic scientists, partners and collaborators of the AWIN project, discussed and agreed on validity, reliability, on-farm feasibility and acceptance by farmers for each indicator. Some aspects of equine welfare have been thoroughly investigated and appear to have indicators ready for on-farm use (eg ‘absence of prolonged hunger’, ‘absence of injuries and diseases’). On the other hand, a lack of animal-based measures were identified for other Criteria such as ‘absence of pain’ and ‘positive emotional state’. Ongoing research within the AWIN project has begun exploring some of the aforementioned Criteria — these preliminary results of promising indicators have been included (eg Horse Grimace Scale and Qualitative Behaviour Assessment). Further research should address the validity and reliability of indicators, such as human-animal relationship tests and signs of cold stress. As well as for working equines, the development and application of a welfare assessment protocol could be the first step for enhancing on-farm equine welfare.

Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed ratio) on gilt and piglet performance during lactation. Thirty-seven PEN and 33 STALL gilts were used. Backfat, litter pre-weaning mortality and total feed intake (TFI) during lactation were recorded in gilts. Weight and rectal temperature was recorded in piglets. In Exp 1 the behaviour of a subsample of gilts was videotaped during lactation. In Exp 2 saliva cortisol in gilts, thyroid stimulating hormone (TSH) and T4 hormones in piglet blood were measured. PEN gilts had more backfat when moved to the farrowing stalls. PEN gilts tended to have higher cortisol concentration 24 h after entering the farrowing stall and to spend more time sitting or standing up one day before parturition than STALL gilts. PEN piglets had higher bodyweight (BW) on day 0 (Exp 2) and lower T4 concentration than STALL piglets. However, STALL piglets showed higher rectal temperature 60 min after birth and lower mortality at day 2. In Exp 2, STALL piglets also had higher BW and average daily gain at weaning. During lactation, PEN gilts lost more backfat and weaned less piglets. Gilts loose-housed with increased feed ratio during gestation might be more stressed when housed in farrowing stalls than those kept in stalls during gestation, thus compromising their offsprings’ thermoregulatory capacity and growth however, from our results, it is difficult to differentiate the effect of feed level from the effect of allocation during gestation.

Vervet monkeys (Chlorocebus pygerythrus) encounter a plethora of anthropogenic risks as a result of their ability to exploit humanaltered environments. A systematic assessment of these risks has not been carried out to date. Here, we aim to begin addressing this gap in our understanding of human-vervet conflict in South Africa. We present a descriptive analysis of the intake of the Vervet Monkey Foundation (VMF) — a specialist vervet monkey rehabilitation centre and sanctuary in the Limpopo Province. Between October 2003 and March 2012 almost 200 vervet monkeys arrived at the VMF. At least 161 infants arrived with a steady decrease in annual intake over time, most probably due to the increasing number of other centres in the province. Detailed data for all age classes were available from March 2009 to March 2012. Of the 50 monkeys that arrived during this period, more young monkeys (infants and juveniles) than adults arrived and more infants than juveniles. Intake of injured and uninjured monkeys was equal. The majority of injuries were caused by cars and the majority of uninjured arrivals were ex-pets handed over voluntarily. A distinct temporal pattern of arrival, peaking in the austral summer, coincides with the birthing season of vervet monkeys in South Africa. The merits of publishing such records and the welfare implications of the perceptions of and objections to these ‘pest’ primates are discussed.
