This special issue on nonhuman primate behavior and welfare, the proceedings of a special Animal Behavior Society session, celebrates the life of Dr. Sylvia Taylor (1963-2005). Sylvia's premature death reminded her friends to recognize the reality that life is short, but one can make the most of it. Many individuals and organizations have also recognized the reality that an educational venture such as this one requires adequate funding and support. Their generosity has made this undertaking a success. The idea behind the session was to recognize the reality that one cannot ensure nonhuman animal welfare without understanding animal behavior, and to explore the ways in which this principle applies to primates. One must also recognize the reality that nonhuman primate welfare depends on understanding the behavior of the human primate as well as the nonhuman primate. Ensuring the welfare of the nonhuman primate sometimes requires educating and motivating the human primate. This special issue will hopefully provide helpful information to increase the reader's knowledge of primate behavior and welfare and to help the reader educate others on these important topics. 相似文献

Animal stereotypies have long been used in the study of obsessive–compulsive disorder (OCD) in humans. These studies have led to the understanding of some of the molecular pathways in the disorder and the use of selective serotonin reuptake inhibitors and myo-inositol in the treatment of these conditions. If animal models, especially nonhuman primate models, were used to study human disorders and if the resulting treatments were successful, then conversely one should be able to treat nonhuman primate stereotypies with similar methods. We here summarize animal models of OCD (including nonhuman primate models) and human OCD treatments, and using successful human treatment by myo-inositol as models, recommend the use of myo-inositol in good captive management practice and the treatment of nonhuman primate stereotypies. We believe that this would be particularly useful in the treatment of stereotypies in nonhuman primates because they are physiologically so similar to humans. 相似文献

Rodents have been traditionally used as a standard animal model in laboratory experiments involving a myriad of sensory, cognitive, and motor tasks. Higher cognitive functions that require precise control over sensorimotor responses such as decision-making and attentional modulation, however, are typically assessed in nonhuman primates. Despite the richness of primate behavior that allows multiple variants of these functions to be studied, the rodent model remains an attractive, cost-effective alternative to primate models. Furthermore, the ability to fully automate operant conditioning in rodents adds unique advantages over the labor intensive training of nonhuman primates while studying a broad range of these complex functions.Here, we introduce a protocol for operantly conditioning rats on performing working memory tasks. During critical epochs of the task, the protocol ensures that the animal''s overt movement is minimized by requiring the animal to ''fixate'' until a Go cue is delivered, akin to nonhuman primate experimental design. A simple two alternative forced choice task is implemented to demonstrate the performance. We discuss the application of this paradigm to other tasks. 相似文献

Evidence exists, particularly in the welfare literature of nonhuman animals on the farm, that the interaction between nonhuman animals and the personnel who care for them can have a strong effect on the animals' behavior, productivity, and welfare. Among species commonly used for biomedical research, mice appear to be the least-preferred species in animal care facilities. A review of the literature and observations of animal care staff interacting with mice indicated that the following factors may influence this: their small size, their particular behavioral characteristics, and husbandry constraints (such as housing in ventilated racks). In addition, this study questioned whether animal care personnel have a different perception of genetically engineered animals and whether this, in turn, has an effect on their interactions with these animals. The ability to carefully observe an animal's behavior is key in carrying out an animal-wellness assessment and in minimizing pain and distress. Attention to human-animal interactions in the research setting represents an opportunity for refinement for large numbers of animals and potentially for reduction of animal use. 相似文献

Animal welfare names a science in which investigators ask the general question: What are the capacities, sensibilities, needs, and interests of animals as they relate to their welfare? The objects of study in this emerging field are exclusively animals other than humans. Numerous contexts give rise to this interest in nonhuman animal welfare: The intensification of the use of animals since World War II, particularly on the farm and in the laboratory. The development of moral philosophies that establish nonhuman animals as objects of moral consideration. The advances in science in fields that have added to our understanding of animals, such as cognitive ethology. Advances in technology that give us more direct access to human physiology and psychology and undercut the tradition of using animal models. The success of the contemporary animal rights movement in placing the issue of the treatment of animals before the public. 相似文献

Investigating how those responsible for the care of nonhuman animals understand the concept of animal welfare is important for animal welfare improvement. In-depth interviews with 31 equine stakeholders were used to explore their perceptions and understanding of welfare. The results showed the stakeholders understood the concept of welfare in 4 ways. Firstly, welfare was understood in terms of the provision of resources—for example, food. Secondly, a “horse-centered” understanding of welfare was articulated; this understanding included the horses' mental state and was linked to natural behavior. Thirdly, the word welfare had negative connotations, and for some, good welfare was achieved through avoidance of negative states. Finally, interviewees discussed incidents that occurred in their own familiar contexts but suggested that these were not welfare problems. Evidence indicated that the ways in which equine stakeholders understood the concept of welfare might have been acting as a barrier to the alleviation of some equine welfare problems. There is a need for strategies aimed at improving equine welfare to consider stakeholder constructs of welfare and the ways in which these constructs are generated and acted upon. 相似文献

A methodological difficulty facing welfare research on nonhuman animals in the zoo is the large number of uncontrolled variables due to variation within and between study sites. Zoo visitors act as uncontrolled variables, with number, density, size, and behavior constantly changing. This is worrisome because previous research linked visitor variables to animal behavioral changes indicative of stress. There are implications for research design: Studies not accounting for visitors' effect on animal welfare risk confounding (visitor) variables distorting their findings. Zoos need methods to measure and minimize effects of visitor behavior and to ensure that there are no hidden variables in research models. This article identifies a previously unreported variable—hourly variation (decrease) in visitor interest—that may impinge on animal welfare and validates a methodology for measuring it. That visitor interest wanes across the course of the day has important implications for animal welfare management; visitor effects on animal welfare are likely to occur, or intensify, during the morning or in earlier visits when visitor interest is greatest. This article discusses this issue and possible solutions to reduce visitor effects on animal well-being. 相似文献

At the 2010 Keystone Symposium on "Malaria: new approaches to understanding Host-Parasite interactions", an extra scientific session to discuss animal models in malaria research was convened at the request of participants. This was prompted by the concern of investigators that skepticism in the malaria community about the use and relevance of animal models, particularly rodent models of severe malaria, has impacted on funding decisions and publication of research using animal models. Several speakers took the opportunity to demonstrate the similarities between findings in rodent models and human severe disease, as well as points of difference. The variety of malaria presentations in the different experimental models parallels the wide diversity of human malaria disease and, therefore, might be viewed as a strength. Many of the key features of human malaria can be replicated in a variety of nonhuman primate models, which are very under-utilized. The importance of animal models in the discovery of new anti-malarial drugs was emphasized. The major conclusions of the session were that experimental and human studies should be more closely linked so that they inform each other, and that there should be wider access to relevant clinical material. 相似文献

As recorded in domestic nonhuman animals, regular interactions between animals in zoos and keepers and the resulting relationship formed (human–animal relationship [HAR]) are likely to influence the animals' behaviors with associated welfare consequences. HAR formation requires that zoo animals distinguish between familiar and unfamiliar people. This ability was tested by comparing zoo animal behavioral responses to familiar (routine) keepers and unfamiliar keepers (participants in the “Keeper for the Day” program). Study subjects included 1 African elephant (Loxodonta Africana), 3 Rothschild's giraffes (Giraffa camelopardalis rothschildi), 2 Brazilian tapir (Tapirus terrestris), and 2 slender-tailed meerkats (Suricata suricatta). Different behavior was evident and observed as decreased avoidance behavior toward familiar keepers (t7 = 6.00, p < .001). This finding suggests the zoo animals have a lower level of fear toward familiar keepers. Keeper familiarity did not significantly affect any other behavioral measure. This finding suggests that in the current study, unfamiliar keeper presence did not appear to have detrimental effects. Furthermore, unfamiliar keeper–animal interactions could provide an increased number of positive human–animal interactions and potentially enhance animal welfare. 相似文献

This essay draws on Adam Smith’s moral sentimentalism to critique primatologist Frans de Waal’s gradualist theory of human morality. De Waal has spent his career arguing for continuity between primate behavior and human morality, proposing that empathy is a primary moral building block evident in primate behavior. Smith’s moral sentimentalism—with its emphasis on the role of sympathy in moral virtue—provides the philosophical framework for de Waal’s understanding of morality. Smith’s notion of sympathy and the imagination involved in sympathy is qualitatively different from animal sympathy. I argue that Smithian sympathy includes the ability to represent propositional attitudes and take into account multiple perspectives which are then synthesized into a singular impartial perspective. Furthermore, Smithian moral judgment requires the capacity for emotion regulation and moral self-cultivation, or the ability to shape and control one’s reactive attitudes. Taken together, these capacities far outstrip the capacities of animals, disrupting de Waal’s gradualism. 相似文献

Intensive pig production systems are a source of stress, which is linked to reduced animal welfare and increased antimicrobial use. As the gatekeepers of the welfare of the animals under their care, farmers are seen as the stakeholder responsible for improving animal welfare. The aim of this study was to explore the knowledge and attitudes of pig farmers towards pig welfare and the impact of such attitudes on farmers' selection of management strategies on the farm. We conducted in-depth semi-structured interviews with 44 pig farmers in one of the main pig producing regions of Brazil. Interviews covered knowledge and attitudes towards pig sentience and behaviour and welfare-related issues commonly observed in intensive pig farms (belly-nosing, fights, tail-biting, diarrhoea and castration without pain control) and farmers' conception and attitudes towards pig welfare. We identified many management and animal-based indicators of poor welfare, such as the use of painful and stressful management practices and use of environments that limit the expression of natural behaviours. However, most farmers were satisfied with animal welfare standards at their farms. Farmers' perceptions are aligned with their understanding of animal welfare. Although they identified all the dimensions that impact the welfare of a pig on a farm (affect, biological functioning and naturalness), their social reality, industry demands and available advice pushed them to perceive their range of action limited to biological and environmental aspects of the animals that do not necessarily benefit affective state. This precluded farmers from making associations between good health and the animal's ability to express a full behavioural repertoire, as well as from viewing abnormal behaviours as problems. The negative consequences for the welfare of the animals were commonly alleviated by routines that relied on constant use of medication, including high dependence on antibiotics. Expressions of estrangement from the production chain were common voices among the participants. This suggests that farmers may not be sufficiently informed or engaged in responding to consumers' expectations and commitments made by companies, which can pose a severe economic risk for farmers. The findings of this study indicate that economic, technical and social factors restrict farmers' autonomy and their ability to perform their role as stewards of animal welfare. (Re)connecting different human, animal and environmental interests may be a step to changing this scenario. 相似文献

Improving the welfare of captive nonhuman primates requires evaluating the stressors created by the captive environment and reducing their negative effects. Social separation, although sometimes necessary for managing the genetic diversity of captive populations of animals, causes both psychological and physiological stress in human and primate monkey infants. Few studies have examined the maternal response of great ape mothers to separation from their offspring. This article describes the behavioral changes of a mother orangutan (Pongo pygmaeus abelii) after separation from her juvenile daughter. We collected data on measures of proximity and social behavior before the separation of the mother-infant dyad and of locomotion, arboreality, abnormal behavior, solitary behavior, and vocalization both before and after separation. We observed no behavioral indications of protest but observed some indications of despair after separation: decreased locomotion, increased inactivity, and increased self-directed behavior. In addition, we observed increases in arboreality and object-oriented behavior during morning sessions. These findings suggest that mother-juvenile separation in orangutans might be less stressful for mothers than might be expected. Such research has implications for the welfare and management of captive animals. 相似文献

The purpose of this study was to gain a better understanding of the current state of stock-type show horse welfare based on the perceptions of show officials and to identify potential means of preventing and intervening in compromises to show horse welfare. Thirteen horse show officials, including judges, stewards, and show managers, were interviewed. Findings revealed the officials had an incomplete understanding of nonhuman animal welfare and a high level of concern regarding the public's perception of show horse welfare. The officials attributed most of the frequently observed compromises to show horse welfare to (a) novices', amateurs', and young trainers' lack of experience or expertise, and (b) trainers' and owners' unrealistic expectations and prioritization of winning over horse welfare. The officials emphasized a need for distribution of responsibility among associations, officials, and individuals within the industry. Although the officials noted recent observable positive changes in the industry, they emphasized the need for continued improvements in equine welfare and greater educational opportunities for stakeholders. 相似文献

Personal willingness to pay, an important research aspect on nonhuman animal welfare, is the foundation of animal welfare legislation. As China has no special laws on the issue, it is important to study animal welfare. This article assesses personal willingness to pay for animal welfare in China, using the Contingent Valuation Method. Based on collected data of 229 visitors from Heilongjiang Northeast Tiger Garden (Harbin), Beijing Zoo, Changchun Zoo and Botanical Garden, Dalian Forest Zoo, and Harbin North Forest Zoo, the study researched willingness to pay for animal welfare and associated influence factors in China. Results showed a high rate of personal willingness to pay (89.5%). Factors such as age, education, and income had obvious effects on personal willingness to pay; however, gender and career had only slight effects. 相似文献

Various nonhuman primate species have been tested with prosocial games (i.e. derivates from dictator games) in order to better understand the evolutionary origin of proactive prosociality in humans. Results of these efforts are mixed, and it is difficult to disentangle true species differences from methodological artifacts. We tested 2- to 5-year-old children with a costly and a cost-free version of a prosocial game that differ with regard to the payoff distribution and are widely used with nonhuman primates. Simultaneously, we assessed the subjects’ level of Theory of Mind understanding. Prosocial behavior was demonstrated with the prosocial game, and did not increase with more advanced Theory of Mind understanding. However, prosocial behavior could only be detected with the costly version of the game, whereas the children failed the cost-free version that is most commonly used with nonhuman primates. A detailed comparison of the children’s behavior in the two versions of the game indicates that the failure was due to higher attentional demands of the cost-free version, rather than to a lack of prosociality per se. Our results thus show (i) that subtle differences in prosociality tasks can substantially bias the outcome and thus prevent meaningful species comparisons, and (ii) that like in nonhuman primates, prosocial behavior in human children does not require advanced Theory of Mind understanding in the present context. However, both developmental and comparative psychology accumulate increasing evidence for the multidimensionality of prosocial behaviors, suggesting that different forms of prosociality are also regulated differentially. For future efforts to understand the evolutionary origin of prosociality it is thus crucial to take this heterogeneity into account. 相似文献

This overview of the current status of medical problems that affect women is related to current studies on pathophysiology and therapeutic interventions using nonhuman primates to demonstrate the utility of the primate model for the study of disease processes in women. The current medical literature on women's health is compared with the literature on nonhuman primate research. The findings reviewed in the articles of ILAR Journal Volume 45 Issue 2 of 2004 are evaluated in the context of the scope and problems associated with disease entities in women. Nonhuman primate research with known information regarding women's disease is discussed, and the utility of the animal model for the study of human disease is highlighted, based on its significant relevance due to similarities of nonhuman primate and human subjects' physiology, metabolism, and responses to therapeutic interventions. Additional advantages of the animal model include the ability to control the experimental environment and the capacity to perform chronic study procedures. These findings allow us to utilize the nonhuman primate as the most relevant model in the animal world for the study of human disease processes. 相似文献

To date, there have been no investigations of the behavioral effects of interleukin-1 (IL-1) in nonhuman primates. In this study the locomotor behavior and vocalizations of juvenile rhesus monkeys were monitored for 45 minutes following intravenous injections of recombinant human IL-1 alpha. In addition, their reaction to a broadcasted recording of infant monkey distress calls was determined 20 minutes after the beginning of each test session. IL-1 induced sleep-like inactivity and significantly diminished the monkey's behavioral and vocal responses to the broadcasted calls. The coo calls uttered by the monkeys following IL-1 treatment also had a longer duration and lower fundamental frequency than calls during the control condition. As several studies have indicated that behavioral effects of IL-1 may be mediated by corticotropin-releasing hormone (CRH), a second group of rhesus monkeys was given injections of CRH. CRH did not alter behavior or call structure at the dose administered. These results extend previous research on the behavioral effects of IL-1 to include the nonhuman primate and provide the first evidence that cytokines can affect vocal communication in rhesus monkeys. © 1995 Wiley-Liss, Inc. 相似文献
