  1. Environmental Enrichments for a Group of Captive Macaws: Low Interaction Does Not Mean Low Behavioral Changes

    Environmental enrichment has been widely used to improve conditions for nonhuman animals in captivity. However, there is no consensus about the best way to evaluate the success of enrichments. This study evaluated whether the proportion of time spent interacting with enrichments indicated the...

  2. Effects of Metabolic Cage Housing on Rat Behavior and Performance in the Social Interaction Test

    Although the metabolic cage is commonly used for housing nonhuman animals in the laboratory, it has been recognized as constituting a unique stressor. Such an environment would be expected to affect behavioral change in animals housed therein. However, few studies have specifically addressed the...

  3. The Effect of an Irregular Feeding Schedule on Equine Behavior

    We used eight horses 1 to 12 years old to investigate the influence of irregular feeding times on the behavior. The animals were housed in individual boxes, fed with hay ad libitum and barley-oat mixture at three set times; 05:00 (earlier feeding) on Thursdays, 07:00 (delayed feeding) on...

  4. The Controversy on Fish Pain: A Veterinarian’s Perspective

    Fish welfare is still a relatively new field. As such, regulations and protocols to ensure fish welfare are currently limited and vary considerably in different jurisdictions. This is in part because of the ongoing controversy as to whether or not fish feel pain. This controversy has persisted...

  5. Complexities of Using Wild versus Captive Activity Budget Comparisons for Assessing Captive Primate Welfare

    Activity budget comparisons between groups or individuals in the wild and those in captivity are commonly used to determine the range of wild-type behaviors that nonhuman animals in captivity perform. These comparisons are conducted with the view that individuals displaying a greater range of...

  6. Companion Animals in Natural Disasters: A Scoping Review of Scholarly Sources

    During a disaster, people may make evacuation decisions based on their companion animal’s welfare, therefore exposing themselves, their companion animals, and emergency responders to increased risk for injury or death. The loss and suffering of companion animals in disasters causes deep distress,...

  7. Behavioral indicators of slow growth in nursery pigs

    The objective of this study was to determine how feeder-space allowance affects behaviors of slow- and fast-growing pigs during the nursery period. Nursery pigs (n = 192; initial weight = 7.4 ± 1.6 kg) were housed in 24 pens of 8 pigs, with 12 pens provided with either a two-space feeder or a...

  8. Behavioral and hematological responses of broiler chickens administered with betaine and ascorbic acid during hot-dry season

    Heat stress is a major problem in poultry production in tropical regions. Assessing the impact of thermally stressful environmental conditions on the welfare of broiler chickens is of great importance. Behavioral responses in a novel environment and hematology of broiler chickens administered...

  9. Behavior and Welfare of Domestic Cats Housed in Cages Larger than U.S. Norm

    The effect of providing additional floor space on cat behavior and welfare is not well documented. This study involved replication of an investigation of cats’ responses to enhanced cage and room environments using cages of 0.56 m2 with the same methodology but an increased space allowance of 1.1...

  10. Behavior and Performance of Dairy Cows After Transfer from Tied to Cubicle Housing

    Behavior and performance changes when tied dairy cows were moved to a loose housing system in a cubicle system were investigated. Behavioral observations were made for 3 consecutive days in 3 periods after transition. The cows (n = 105) were observed on 18 sampling occasions for 1 month....

  11. Advances in Applied Zoo Animal Welfare Science

    Nonhuman animal welfare science is the scientific study of the welfare state of animals that attempts to make inferences about how animals feel from their behavior, endocrine function, and/or signs of physical health. These welfare measurements are applicable within zoos yet inherently more...

  12. Abandonment of Dogs and Cats: Public Opinions as Population Management Indicators

    This study involved characterizing public opinions on selected issues related to the abandonment of dogs and cats in Votorantim, São Paulo, Brazil. This goal was achieved by applying multiple correspondence analysis to answers recorded in questionnaires of a population-based survey. The results...

  13. Lancaster Pet Cemetery Memorial Plaques 1951–2018: An Analysis of Inscriptions

    Individuals in many cultures have a close relationship with their pets and think of them not only as companion animals but also as family. Research on the ways in which people memorialize their deceased pets has become increasingly important, and pet cemetery gravestone inscriptions have provided...

  14. Measuring the Strength of Human–Animal Bonds in Zoos

    Repeated interactions within individual human and animal dyads can lead to the establishment of human–animal relationships (HARs), which may vary in quality from good to bad, defined in terms of the positivity (e.g., friendly contact, play) or negativity (e.g., aggression) of the interactions on...

  15. The Anthropomorphic Application of Gender Stereotypes to Horses

    Gender stereotypes shape human social interaction, often to the detriment of women and those who do not comply with normative expectations of gender. So far, little research has assessed the extent to which people apply gender stereotypes to animals, and the implications this may have for...

  16. Exploring the Meaning and Experience of Chronic Pain with People Who Live with a Dog: A Qualitative Study

    Pain is a significant burden for those with chronic disease and negatively impacts quality of life, causing disability and substantial work and health-care costs. Chronic pain has been identified as one of the most important current and future causes of morbidity and disability across the world....

  17. Measuring Quality of Life in Owners of Companion Dogs: Development and Validation of a Dog Owner-specific Quality of Life Questionnaire

    Numerous studies have examined the link between companiondog ownership and improved physical or psychological health outcomes; however, few have examined the association between dog ownership and owners’ overall wellbeing or quality of life (QOL). Moreover, the potential for dog ownership to...

  18. Using Attachment Theory and Social Support Theory to Examine and Measure Pets as Sources of Social Support and Attachment Figures

    Companion animals are increasingly being recognized by society as beneficial to our health and considered by many owners as authentic and affectional family members. Human relationship theories help us to understand the emotional and supportive aspect of the human– companion animal bond. This...

  19. Evaluating the Impact of a Humane Education Summer-Camp Program on School-Aged Children's Relationships with Companion Animals

    This study evaluated the impact of children's participation in a five-day humane education summer-camp program on the quality of their relationships with and treatment of companion animals. We measured changes from pre- to post-program in 77 children (50 girls, 27 boys) aged 6–12 years. The...

  20. What is the relationship between level of infection and ‘sickness behaviour’ in cattle?

    We hypothesised that a range of parasite doses that cause subclinical disease would lead to similar behavioural changes in cattle. This was tested by infecting bull calves with one of four different doses of the gastrointestinal parasite Ostertagia ostertagi: 0 (control), 75,000 (L), 150,000 (M)...
