In the social, historical, and political context of Xi Jinping’s China, particular forms of racialization and racial capitalism have emerged in Altay Prefecture, the homeland of ethnic Kazakhs on China’s northwest border. This study examines the husbandry industry in Altay Prefecture to elucidate how Xi’s China has built a mode of racial capitalism through the management of Kazakh land, ethnicity, and culture. Within the framework of a case study, I employ document collection and participant observation methods to gather data that are then interpreted through critical policy analysis. The research shows that Kazakhs have been racialized based on their mobile pastoral traditions, enslaved in the “debt economy,” and exploited through husbandry policies and programs. The particular ways in which husbandry has been restructured and assimilated into Chinese industrial production chains exploit and reproduce the Kazakh-Han hierarchy and segregation. This close look at racial capitalism in Altay sheds light on the operations of Xi’s ecological civilization and war on poverty policies in an ethnic minority border region and discusses how they align with the broader geopolitics of the Belt and Road Initiative in Central Asia and Eastern Europe.

Concerns over compromised companion rabbit (Oryctolagus cuniculus domesticus) welfare are widespread. The welfare problems have been linked to the perception of rabbits as low investment ‘children’s pets.’ To test this hypothesis and investigate the current conditions for rabbits, data were gathered from two surveys in 2021: a nationally representative survey of Danish companion animal owners (Survey I) and a detailed social media-based survey of Danish rabbit owners (Survey II). Using logistic regression, three owner-related variables (whether a child/adult was responsible for care of the rabbit, owner-opinion on rabbits’ suitability as ‘starter pets’ and willingness-to-pay [WTP] for veterinary treatment) were employed to investigate the effect of rabbit status on owner-provision of selected husbandry conditions. The 76 (Survey I) and 4,335 (Survey II) responses suggested that most rabbits are acquired for children and are solitarily housed, and that many are kept in cages of an unsuitable size and not checked daily. Owners who perceived rabbits as ‘starter pets’ and with lower WTP were more likely to house rabbits in restricted space and to not provide continuous gnawing opportunities, ad libitum hay or routine healthcare. A child fulfilling the role of the rabbit’s main caretaker was also associated with inadequate housing type and fewer gnawing opportunities. Thus, many rabbits live in unsuitable conditions, and owners who perceive rabbits as low investment ‘children’s pets’ are more likely to not provide recommended resources. Changing owners’ perceptions of rabbits and promoting suitable husbandry through official education programmes and minimum requirements is important if there are to be improvements made to rabbit welfare.

Expectations of retailers and consumers regarding animal health and welfare and meat quality are particularly high for organic products. The aim of this study was therefore to provide an overview of the health and welfare of pigs on organic farms in Austria. Eighty-four organic pig farms were investigated. The farmers were interviewed using a questionnaire. In addition to clinical examination, the pigs were monitored at slaughter to determine the prevalence of organ lesions. The average herd size was 20.1 productive sows in the sow units and 84 fattening pigs in the finishing units. All farms used indoor production systems and provided straw to the pigs. Pregnant sows and finishers had access to an outdoor run in more than 90% of farms, but less than 15% of farms had outdoor runs for lactating sows and weaners. In more than 75% of the herds, endoparasites were found in faecal samples. About 50% of slaughter pigs displayed milk spots on the liver, 24% had pneumonic lesions and 18% showed mange. The results indicate that preventive measures in husbandry, management and hygiene must be intensified to improve animal health and welfare on organic pig farms and to meet the expectations of the consumers.

Laboratory primates are often housed in same-sex pairs to avoid single-housing and when breeding is to be prevented. However, pair formation is not without risks, as fights and injuries may occur. No data are available on pair formation in female common marmosets (Callithrix jacchus), a species used extensively in laboratories. Therefore, this study focuses on the pairing of unfamiliar common marmoset females, aiming to assess its success rate and whether age can predict the result. Data on the study animals and success of the pairings were extracted from laboratory back-records: a total of 28 pairings was obtained. In addition, behavioural data were collected on six of the 28 pairs. Almost 80% of pairs were compatible beyond one week, and most of the fights occurred well within the first week after pair formation. Pairs in which one of the females was sexually immature (ie < 15 months) were significantly more compatible than pairs in which both females were post-pubertal. First encounters were characterised by sniffing of the unfamiliar monkey. Aggressive behaviours occurred frequently following pair formation but they were unidirectional, and in only two pairs was veterinary treatment required. This study shows that pairing of unfamiliar common marmoset females is a safe practice if one monkey is sexually immature, a result that supports observations of both group and pair formation in other primate species. However, given the potentially detrimental effects of removing young females from their natal groups, we argue that it is preferable to remove two sisters from their natal group when female pairs are required. However, when a single sexually mature female requires a pair mate so as to avoid single-housing and no mature sibling is available, an older, but still sexually immature, unfamiliar female that has had a normal development within the family should be considered as a pair mate.

In order to safeguard the welfare of laboratory-housed non-human primates, refinement techniques should be applied to every aspect of the life of animals used in the laboratory, from birth to death, with the aim of both minimising harm and maximising well-being. In this second part of a three-part review we summarise published information on housing and husbandry practices, and describe ways to minimise contingent inhumanity associated with the use of primates in laboratories and their breeding and supply (where inhumanity is defined as the infliction of distress). We also discuss methods by which the welfare of these animals can be maximised on a day-to-day basis. The principles of enrichment, aspects of the housing environment, social and physical enrichment and acquisition are discussed. Refinement of the influence of humans and experimental procedures are discussed in Parts I and III of this review, respectively.

The use of woodchips as bedding for 16 juvenile chimpanzees (Pan troglodytes) was evaluated for the effects on behaviour, health and husbandry practices. Woodchip bedding was placed in two outdoor play areas for five consecutive days. Behavioural data were recorded in the morning and afternoon of each day, and compared to pre- and post-test data. A total of 44 hours of observations, made up of 1 hour scan sample sessions, were completed for the study. Behaviours in the following categories were measured: abnormal, affinitive, aggressive, environmental manipulation, inactivity, locomotion, play, self manipulation and woodchip manipulation. The location of each animal was also recorded Analysis of the data indicated that the chimpanzees engaged in woodchip-related behaviours for an average of 20.52 per cent of the data points, and that they spent more time manipulating the substrate in the morning than in the afternoon. In addition, abnormal behaviour, environmental manipulation and affinitive behaviours were significantly lower during the woodchip condition than during pre-test and post-test conditions. The subjects spent the most time on the floor of the enclosure, and this measure did not differ between conditions. The woodchip bedding did not cause any known health problems for the chimpanzees. Although the daily addition and removal of woodchips took more time than did routine cleaning, it kept the play areas cleaner and drier. The evaluation of woodchip bedding as enrichment was favourable and indicated that bedding may be used regularly in the maintenance of captive chimpanzees.

Much attention has been focused, quite rightly, on the welfare of laboratory rodents and farm animals but certain other groups have been less well represented in welfare research. Small birds, for example, are often kept as pets and used in a wide variety of behavioural and physiological experiments where ‘best’ housing conditions are based on advice from experienced keepers as opposed to being tested experimentally. We investigated the effects of two husbandry conditions on the welfare of captive zebra finches: a) optional cover and b) rewarded handling versus random rewards. As a correlate of welfare in the four conditions (cover + reward, cover, reward, nothing), we recorded the time to settle and perform normal behaviours after an experimenter entered the room throughout the study (ie habituation to disturbance). In addition, we measured female preference for males in the four conditions to see whether welfare situation affected attractiveness as a mate. Birds in the two conditions where a reward was provided settled most quickly; and their settling time decreased across the study. Birds provided with cover alone became more disturbed by the entry of the experimenter as the study progressed. However, the birds taking longest on average to settle were those in cages with no cover and no reward. Females preferred males in the reward conditions as mates, either due to the fact that these males settled more quickly or because less-stressed males are more attractive in some other way. Thus, rewarding birds after disturbance is an effective and simple way to improve habituation to handling and human presence. In addition, these birds are more attractive to females, implying that males more habituated to captivity may be preferred as mates. Provision of cover may help under certain circumstances, but appears paradoxically to lead to increased fearfulness over time under the conditions studied here.

In rodents, cage cleaning increases cardiovascular and behavioural activity for several hours, which are commonly interpreted as stress responses. In mice, post-cleaning activity also includes aggression, which can cause serious injuries. This study was part of a long-term investigation into the effects of cage cleaning frequency on rat behaviour and welfare. Here we aimed to ascertain whether post-cleaning activity is stress- or aggression-related, thereby leading to recurrent acute reductions in welfare, or simply a result of non-aversive stimulation. Male Wistar (n = 160) and Sprague–Dawley (n = 160) rats, kept in four animal units, had their cages cleaned twice per week, once per week or once per fortnight, and were kept on one of two types of bedding. Behaviours were recorded in detail before and after cage cleaning for 20 weeks, as was the aversion-related Harderian gland secretion, chromodacryorrhoea (‘red tears‘). Cage cleaning caused decreased resting and increased feeding, walking, bedding manipulation and sheltering for at least 30 min after the disturbance. Skirmishing also increased markedly for 15 min after cleaning, but decreased thereafter to below baseline levels. Unlike in mice, all skirmishing was non-injurious and play-like. The frequency of cage cleaning did not affect the magnitude of this skirmishing peak, but rats that had their cages cleaned more frequently settled more quickly after cleaning. Surprisingly, chromodacryorrhoea decreased after cage cleaning; this could mean that rats find soiled cages stressful or alternatively, like many disturbances, cage cleaning might provoke frequent, curtailed bouts of grooming, thereby removing the secretion. Rats also manipulated aspen bedding more than paper bedding. Overall, we found no evidence that cage cleaning caused rats any acute decrease in welfare — a finding consistent with additional data we have obtained on the lack of preference by rats for soiled over clean cages, and a lack of long-term, behavioural and physiological responses to being cleaned frequently or infrequently.

Given the absence of a ‘Golden Standard’ for the objective determination of welfare, the collection and interpretation of data involving different parameters is essential for assessing the well-being of farm animals. The choice of parameters and the relative weights assigned to each of them are crucial for the outcome of the assessment. Both elements involve a certain degree of subjectivity. In this paper we discuss the basics of different methods used to integrate welfare parameters, focussing on the issue of scientific objectivity. We begin by addressing parameter selection, the assignment of parameter weightings or rankings and the qualifications necessary for ‘experts’ designing and applying the methodology. Five different approaches to integrating parameters are then discussed. The paper does not state a preference for any method, but aims to encourage discussion of key elements involved with the on-farm assessment of welfare.

A study was carried out during the period from September 2001 to August 2002 in Jimma zone, western Ethiopia to evaluate the husbandry and health of captive African civets (Vivera civetica). Wild civets were found in the wild in all 13 of the districts in the zone, although traditional civet-keeping was practiced in only five. Civet management practices were determined via the use of a questionnaire survey of 15 farms; containing a total of 107 civets. Health was assessed by routine clinical examination, and examination of faecal and blood smears of 55 civets selected at random. All civets were male and over one year of age, with a mean weight of 12.5 ± 0.79 kg. Fifteen percent were in poor body condition, and only 13% had a good body condition score. An average of 7.13 civets were kept on each farm. Farmers obtained wild civets by either trapping them themselves, purchasing them from dealers or a combination of both. The civets were housed separately in wooden cages, with an average size of 1.0 × 0.5 × 1.0 m (length × breadth × height) and kept in a communal thatched room. They were fed boiled meat, milk (fresh or powdered), eggs, butter, corn soup and fruit juice. Although an assessment of the behavioural parameters of welfare were outwith the scope of this study, trapping methods, adaptation processes, housing condition, restraint and the techniques for musk extraction from the anal glands were stressful and injurious, and have important welfare implications. Approximately 20 g of musk was expressed from a single civet every 9-15 days. The civets often sustained injuries while being restrained during musk harvesting; 14% had swelling and bruising, 6.5% fractures and 11.2% had eye lesions. Cestodes were the most prevalent gastrointestinal parasites, followed by ancylostomes, ascarides and Tricuris spp. Skin lesions were identified in 19.6% of civets examined and an assortment of fleas and ticks including Haemophysalis leachi, Rhipicephalus and Amblyoma spp were found on the body. Trypanosoma congolense and Babesia felis were identified in blood smears taken from four animals. This study shows there is an urgent need to invest in research into improving the welfare, husbandry and health of civets, as well as providing educational programmes for those who farm these animals.

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.

New livestock housing systems designed to improve animal welfare will only see large-scale commercial adoption if they improve profitability, or are at least cost neutral to the farm business. Economic evaluation of new system developments is therefore essential to determine their effect on cost of production and hence the extent of any market premium necessary to stimulate adoption. This paper describes such an evaluation in relation to high welfare farrowing systems for sows where any potential system needs to reconcile the behavioural needs of the sow with piglet survivability, acceptable capital and running costs, farm practicality and ease of management. In the Defra-sponsored PigSAFE project, a new farrowing system has been developed which comprises a loose, straw-bedded pen with embedded design features which promote piglet survival. Data on this and four other farrowing systems (new systems: 360° Farrower and a Danish pen; existing systems: crate and outdoor paddock) were used to populate a model of production cost taking account of both capital and running costs (feed, labour, bedding etc). Assuming equitable pig performance across all indoor farrowing systems, the model estimated a higher production cost for non-crate systems by 1.6, 1.7 and 3.5%, respectively, for 360° Farrower, Danish and PigSAFE systems on a per-sow basis. The outdoor production system had the lowest production cost. An online survey of pig producers confirmed that, whilst some producers would consider installing a non-crate system, the majority of producers remain cautious about considering alternatives to the farrowing crate. If pig performance in alternative indoor systems could be improved from the crate baseline (eg through reduced piglet mortality, improved weaning weight or sow re-breeding), then the differential cost of production could be reduced. Indeed, with further innovation by pig producers, management of alternative farrowing systems may evolve to a point where there can be improvements in both welfare and pig production. However, larger data sets of alternative systems on commercial farms will be needed to explore fully the welfare/production interface before such a relationship can be confirmed for those pig producers who will be replacing their units in the next ten years.

A comprehensive synopsis of the welfare of captive, wild (ie non-domesticated) animals in travelling circuses is missing. We examined circus animal welfare and, specifically, behaviour, health, living and travelling conditions. We compared the conditions of non-domesticated animals in circuses with their counterparts kept in zoos. Data on circus animals were very scarce; where data were absent, we inferred likely welfare implications based on zoo data. Circus animals spent the majority of the day confined, about 1-9% of the day performing/training and the remaining time in exercise pens. Exercise pens were significantly smaller than minimum zoo standards for outdoor enclosures. Behavioural budgets were restricted, with circus animals spending a great amount of time performing stereotypies, especially when shackled or confined in beast wagons. A higher degree of stereotyping in circuses may be indicative of poorer welfare. Inadequate diet and housing conditions, and the effects of repeated performances, can lead to significant health problems. Circus animals travel frequently and the associated forced movement, human handling, noise, trailer movement and confinement are important stressors. Although there is no conclusive evidence as to whether animals habituate to travel, confinement in beast wagons for long timeperiods is a definite welfare concern. Circuses have a limited ability to make improvements, such as increased space, environmental enrichment and appropriate social housing. Consequently, we argue that non-domesticated animals, suitable for circus life, should exhibit low space requirements, simple social structures, low cognitive function, non-specialist ecological requirements and an ability to be transported without adverse welfare effects. None of the commonest species exhibited by circuses, such as elephants and large felids, currently meet these criteria. We conclude that the species of non-domesticated animals commonly kept in circuses appear the least suited to a circus life.

The objective of this study was to determine if housing conditions, specifically pen size and soil enrichment, had an effect on faecal glucocorticoid concentrations in the endangered pygmy rabbit (Brachylagus idahoensis). The success of the captive breeding programme has been limited, so one hypothesis is that chronic stress due to sub-optimal housing conditions may be responsible for poor fecundity. Faecal glucocorticoid concentrations were assessed in 50 females housed among several pen types at two breeding facilities. The highest glucocorticoid concentrations were found in females housed in 0.37 m2 crates as compared to enclosures ranging from 0.96 to 75 m2 in size. Results also indicated that enrichment of enclosures with soil had a significant influence on adrenal activity, based on a reduction in glucocorticoid excretion for females moved from non-soil pens to those with soil. Last, a significant facility effect on glucocorticoid concentrations was observed, suggesting that factors other than housing influenced adrenal activity in these rabbits. In conclusion, based on measurements of faecal glucocorticoids, pygmy rabbits are best managed in enclosures that contain soil for digging burrows. Pen size had little effect on stress hormones, except for crates where limited space and/or absence of soil was associated with higher glucocorticoid concentrations. These results underline the importance of monitoring glucocorticoid concentrations in captive breeding programmes to identify optimal husbandry and management practices.

Traditional husbandry practices for the public display of Callitrichidae involve strict separation of animals and public. An important consideration for the evaluation of such management is the occurrence of health problems and potential zoonotic risks. This study compared animal data and veterinary records from a captive, free-roaming population of golden-headed lion tamarins (Leontopithecus chrysomelas) with a population housed under indoor management. The captive, free-roaming group grew significantly faster than the indoor-housed group, as less animals died and offspring were more successfully weaned. No differences in the causes of death were detected between the two husbandry practices. However, bacterial diseases were most common and diagnosed significantly more often under indoor management. This study suggests that the captive, free-roaming management of golden-headed lion tamarins can be conducive to increased reproductive success, improved health and improved welfare. Therefore, current husbandry recommendations for captive, free-roaming conditions were supported by the findings of the present study as a valuable housing practice where health regulations and proper husbandry parameters permit.

Managing and assessing well-being in laboratory mice (Mus musculus) is both challenging and necessary. Assessments intended to detect negative welfare states in mice are usually performed via observation of animals in the home cage, but a substantial amount of time and skill may be required to detect subtle behavioural changes. The Time to Integrate to Nest Test (TINT) is a simple, cageside assessment tool that identifies the presence or absence of a highly motivated normal behaviour in mice. The test is conducted by adding a small amount of new nesting material to a mouse cage. A positive outcome is achieved when this new material is integrated into the home nest within 10 min. This study examined whether housing condition or nesting experience affects TINT outcome. Single or group housing did not influence the TINT outcome, but a significant difference in latency to integration was found; singly housed mice took longer than group-housed mice to integrate TINT substrate. Mice which were raised naïve to nesting material had no significant delays when tested. However, experience with the TINT procedure showed increased speed to incorporate the testing substrate, indicating that previous experience to the paradigm prior to experimental testing may be necessary. These findings help to define the expected outcomes of the TINT, better positioning it for use as an assessment tool in varied research settings.

The welfare of captive animals is influenced by their ability to express natural behaviours. Foraging is one behaviour that may be particularly important in this respect; many species will continue to work for food even when it is freely available. The role of substrate, and in particular particle size, on the foraging behaviour of goldfish (Carassius auratus) was examined through three repeated measures experiments. In the first, tanks were set up with five uniform substrates: plastic grid, coarse sand, fine gravel, pebbles, and cobbles. In the second, fish were provided with a choice between coarse sand and fine gravel, fine gravel and pebbles, and pebbles and cobbles. In the third, they were provided with two choices between coarse sand and cobbles, one where the sand contained more food and one where the cobbles did. Our results show that particle size significantly affected the amount of time goldfish spent foraging, and that goldfish exhibited foraging behaviour even in the absence of a substrate they can manipulate. Goldfish foraged longest when provided with coarse sand. Fish foraged significantly longer over smaller particle size substrates when given a choice, although they did not distinguish between the two finest substrates, coarse sand and gravel. Increases in total time spent foraging were achieved through more, rather than longer, bouts. Food density did not significantly alter preference for smaller particle substrates. In general, coarse sand (1.5 mm) was found to be the most appropriate substrate in terms of facilitating natural foraging behaviours. These findings are discussed with respect to the welfare and husbandry of goldfish and aquarium fish in general.

The attitudes of experts towards the husbandry of captive Great Apes was sought in order to gain a greater understanding of the potential importance of different features of the captive environment that may be critical in maintaining a high standard of welfare. Following initial consultation with the convener of the Primate Taxon Advisory Group of the Australasian Regional Association of Zoological Parks and Aquaria, 17 husbandry attributes, such as social structure of the group, enclosure size and staff qualifications, each with two to four levels (ie husbandry scenarios) of possible provision in an enclosure were identified and described. An online survey using Adaptive Conjoint Analysis was distributed internationally to relevant stakeholders: zoo management staff, keepers and education staff, research colony personnel, veterinarians, animal welfare organisation representatives and scientists. A total of 359 respondents completed the survey, and the average importance values for the attributes, and rank order of importance for each of their levels were calculated. Great Ape social structure, enclosure appearance, group size, avoidance provision and enclosure furnishings were considered the most important attributes of captive Great Ape husbandry, whereas feeding interval, staff qualifications, the inclusion of plants within the enclosure, enrichment rotation, and the amount of time an animal spent in an outdoor enclosure were considered of low importance. The order in which these issues were ranked was influenced by the Great Ape species, with physical attributes of the enclosure being rated as more important for orangutans (Pongo pygmaeus) and group social attributes more important for the other species. Stakeholder group had little influence on the ranking of issues. It is concluded that experts provided a consensus view on the importance of husbandry attributes of the different Great Ape species that can be used to evaluate their welfare.

Husbandry training and environmental enrichment are both important advancements associated with current behavioural welfare practices. Additionally, the use of training procedures has been proposed as a form of enrichment, with the implication that training can produce beneficial behavioural welfare results. This paper examines the concept of training as enrichment through three distinct ways training procedures could enrich: (i) training facilitates enrichment usage; (ii) training modifies interactions, conspecific or otherwise; and (iii) training expands behavioural repertoires. Within each category, the paper focuses on past research that provides empirical support for training functioning as enrichment, as well as related areas of research that provide additional evidence. Previous studies support the claim that training is enriching, with additional research necessary to better understand how prevalent and under what conditions training procedures function as enrichment. Future training research should examine these potential enrichment effects, including methodology that allows for comparisons to traditional enrichment, the use of welfare diversity/variability indices, and the effects of learning on trainers and trainees alike.
