  1. Evaluation of operant learning in young foals using target training

    Contributor(s):: Martinez de Andino, Elena V., McDonnell, Sue M.

    The primary purpose of this study was to characterize operant learning performance of young foals. For each of 26 foals, aged 6–20 weeks, learning performance was quantitatively evaluated in a single brief training trial using a standard operant conditioning task and paradigm analogous to those...

  2. Effects of single-use and group-use enrichment on stereotypy and intragroup aggressive and affiliative behaviors of a social group of squirrel monkeys (Saimiri sciureus) at the Singapore Zoo

    Contributor(s):: Sha, J., Han, S., Marlena, D., Kee, J.

    Four food-based enrichment devices were used to test the effects of single-use and group-use enrichment devices on stereotypy, intragroup aggression, and affiliation in a compatible group of 5 squirrel monkeys (Saimiri sciureus). All enrichment devices were found to reduce overall stereotypic...

  3. Trends in sheltering and welfare at the Hawaiian Humane Society, Oahu, Hawaii

    Contributor(s):: McDowell, B., Burns, P., Lepczyk, C. A.

    One of the major goals of an animal welfare organization is to reduce the number of homeless, nonhuman animals in a community. In Hawaii, the Hawaiian Humane Society has provided numerous animal welfare services to work toward this goal, such as offering sterilizations and microchipping at...

  4. Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo

    Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.

    Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...

    Contributor(s):: Sandig, Christine

  6. Breeding for better welfare: genetic goals for broiler chickens and their parents

    Contributor(s):: Steensels, M., Bahr, C., Berckmans, D., Halachmi, I., Antler, A., Maltz, E.

  9. Verbal Attention Getting as a Key Factor in Social Learning Between Dog (Canis familiaris) and Human

  10. Loading the problem loader: The effects of target training and shaping on trailer-loading behavior of horses

    Contributor(s):: Ferguson, Dawnery L., Rosales-Ruiz, Jesús

  11. Development and validation of a new method for visual detection of estrus in mithun ( Bos frontalis )

    Contributor(s):: Mohan, Mondal, Muthupalani, Karunakaran, Chandan, Rajkhowa, Prakash, B. S.

    The objectives of this study were (1) to develop a suitable scoring scale for oestrus detection based on frequency and reliability of behavioural signs of oestrus in mithun (Bos frontalis) and (2) to validate the accuracy of this method for detection of oestrus in primi- and multiparous mithun...

  12. Development with age of nest box use and gregarious nesting in laying hens

    Contributor(s):: Riber, A. B.

    Use of nest boxes is an important part of the behavioural repertoire of laying hens kept under commercial conditions. A special form of nest box use is gregarious nesting, which occurs when a hen given the choice between an occupied and an unoccupied nest site chooses the occupied nest site....

  13. Navigational ability in the domestic fowl ( Gallus gallus domesticus )

    Contributor(s):: Zimmerman, P. H., Pope, S. J., Guilford, T., Nicol, C. J.

    Little is known about the navigational abilities of domestic fowl. The question of how chickens represent and orient in space becomes relevant when they are kept in non-cage systems. Since the sun is known to be the dominant spatial organizer in other diurnal bird species, we started our...

  14. Reliability and inter-test relationship of tests for on-farm assessment of dairy cows' relationship to humans

    Contributor(s):: Windschnurer, I., Schmied, C., Boivin, X., Waiblinger, S.

    Animals' relationship to humans, i.e., their perception of humans, is an important parameter to be included into on-farm welfare assessment schemes. The objectives of this study were to evaluate inter-observer reliability and between-experimenter repeatability of three previously used and two new...

  15. Animal-visitor interactions in the modern zoo: conflicts and interventions

    Contributor(s):: Fernandez, E. J., Tamborski, M. A., Pickens, S. R., Timberlake, W.

    Animal welfare, education, conservation, research, and entertainment are major goals of modern zoos, but they can be in conflict. For example, visitors enjoy learning about and observing natural behavior in captive animals, but visitors often want to observe and interact with the animals in close...

  16. Impact of riding in a coercively obtained Rollkur posture on welfare and fear of performance horses

    Contributor(s):: Borstel, U. U. von, Duncan, I. J. H., Shoveller, A. K., Merkies, K., Keeling, L. J., Millman, S. T.

    Rollkur, the usually coercively obtained hyperflexion of the horse's neck, is employed as a training method by some dressage riders; however, its use is controversial as it may cause discomfort and adversely affect the horse's welfare. The objectives of this study were to determine: (1) if horses...

  17. The effect of early human contact and the separation method from the dam on responses of beef calves to humans

    Contributor(s):: Boivin, X., Gilard, F., Egal, D.

    The objectives of this experiment were to evaluate the effect of early human contact and of the separation method from the dam on the future relationships of calves with humans, and to investigate the relationship between dam responses and calf responses. Thirty-three Salers calves aged 2-4 days...

  18. The effect of randomly altering the time and location of feeding on the behaviour of captive coyotes ( Canis latrans )

    Contributor(s):: Gilbert-Norton, L. B., Leaver, L. A., Shivik, J. A.

    Captive carnivores appear highly susceptible to the negative effects of predictable feeding routines. Current research and reviews suggest feeding unpredictably may increase species typical behaviour, but positive results have been limited to a few species. Our objectives were to determine...

  19. Four types of activities that affect animals: implications for animal welfare science and animal ethics philosophy

    Contributor(s):: Fraser, D., MacRae, A. M.

    People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology...

  20. The contribution of animals to human well-being: a veterinary family practice perspective

    Contributor(s):: Timmins, R. P.

    There is considerable evidence that humans can benefit both physically and emotionally from a relationship with companion animals, a phenomenon known as the human-animal bond (HAB). This has not only increased the demand for veterinary services to meet the needs of these non-human family members...
