  1. Assessing feeding motivation in sheep using different behavioural demand models and measures

    Contributor(s):: Doughty, Amanda K., Ferguson, Drewe, Matthews, Lindsay R., Hinch, Geoff N.

    Motivation tests have been used to assess the strength of an animals drive to obtain specific resources and, indirectly to gain insight into the animal’s welfare state as it is likely that chronic high motivation for unobtainable resources leads to diminished welfare. A variety of measures have...

  2. A veterinary perspective on preventing injuries and other problems that shorten the life of working dogs

    Contributor(s):: Worth, A. J., Cave, N. J.

  3. Characteristics of Excitable Dog Behavior Based on Owners' Report from a Self-Selected Study

    Contributor(s):: Anastasia Shabelansky, Seana Dowling-Guyer

    Past research has found that excitable dog behavior is prevalent among sheltered and owned dogs and many times is a reason for canine relinquishment. In spite of its prevalence in the canine population, excitable behavior is relatively unstudied in the scientific literature. The intent of this...

  4. Oxygen Cost of Recreational Horse-Riding in Females

    Contributor(s):: Beale, L., Maxwell, N. S., Gibson, O. R., Twomey, R., Taylor, B., Church, A.

  5. Recommended management strategies to limit anthropogenic noise impacts on greater sage-grouse in Wyoming

    Contributor(s):: Patricelli, Gail L., Blickley, Jessica L., Hooper, Stacie L.

  6. Stakeholder contemporary knowledge needs regarding the potential effects of tall structures on sage-grouse

    Contributor(s):: Messmer, Terry A., Hasenyager, Robert, Burruss, James, Liguori, Sherry

  7. Energy intake and expenditure of improvised explosive device detection dogs

    Contributor(s):: Phillips, S. P., Kutzner-Mulligan, J., Davis, M.

    Improvised explosive device detection (IDD) dogs explore up to 40 km of land daily and therefore have energetic demands that may be above the National Research Council's requirement for working dogs. This study was designed to quantify metabolic energy intake (MEI) and total energy expenditure...

  8. Maintenance energy requirements of odor detection, explosive detection and human detection working dogs

    Contributor(s):: Mullis, R. A., Witzel, A. L., Price, J.

    Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint...

  9. A test of "nutritional wisdom" in perch ( Perca fluviatilis) by self-selection of encapsulated macronutrients

    Contributor(s):: Brannas, E., Strand, A.

    Developing optimal diets based on fish macronutrient requirements is an expensive and laborious task requiring years of research. However, many species of fish can compose a species-specific optimal diet from single source macronutrients in capsules through self-selection. Eurasian perch is a...

  10. Understanding feeding patterns in growing pigs by modelling growth and motivation

    Contributor(s):: Boumans, I. J. M. M., Bokkers, E. A. M., Hofstede, G. J., Boer, I. J. M. de

    Feeding is an essential behaviour for body maintenance in pigs and closely related to their growth and productivity performance. Mechanisms underlying feeding behaviour in pigs are still unclear. Understanding these mechanisms can provide valuable insights into the complex interactions among...

  11. Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females

    Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.

    An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...

  12. The rationality of biofuel certification: a critical examination of EU biofuel policy

    Contributor(s):: Pols, A. J. K.

    Certification for biofuels has been developed to ensure that biofuel production methods adhere to social and environmental sustainability standards. As such, requiring biofuel production to be certified has become part of EU policy through the 2009 renewable energy directive (RED), that aims to...

  13. Is Fido fat? Is your tabby flabby?

  14. Nutritional ecology of obesity: from humans to companion animals

    Contributor(s):: Raubenheimer, D., Machovsky-Capuska, G. E., Gosby, A. K., Simpson, S.

    We apply nutritional geometry, a framework for modelling the interactive effects of nutrients on animals, to help understand the role of modern environments in the obesity pandemic. Evidence suggests that humans regulate the intake of protein energy (PE) more strongly than non-protein energy...

  15. Pushed to the limit: food abundance determines tag-induced harm in penguins

    Contributor(s):: Wilson, R. P., Sala, J. E., Gomez-Laich, A., Ciancio, J., Quintana, F.

    The energetic costs of animal movement change with body condition, although the consequences of this for foraging efficiency are rarely considered. We deployed externally attached devices to Magellanic penguins ( Spheniscus magellanicus), known to increase the costs of swimming via increased drag...

  16. Number of nearby visitors and noise level affect vigilance in captive koalas

    Contributor(s):: Larsen, M. J., Sherwen, S. L., Rault, J. L.

    Understanding human-animal interactions is particularly important for institutions that display animals to the public due to the frequent, and sometimes intense, interactions with unfamiliar humans. Past research has shown that visitors can have a negative impact on the welfare of a wide range of...

  17. Activity patterns in reindeer with domestic vs. wild ancestry

    Contributor(s):: Reimers, E., Tsegaye, D., Colman, J. E., Eftestol, S.

    We analyzed GPS-based activity patterns for two wild reindeer ( Rangifer tarandus tarandus) herds: Norefjell-Reinsjofjell with domestic ancestry and larger average body size and Rondane with wild ancestry and smaller body sizes. We compared activity patterns and tested whether these could...

  18. Pet Your Dog: Dog Breeds

    Listings and descriptions of dog breeds.

  19. Which measures of acceleration best estimate the duration of locomotor play by dairy calves?

    Contributor(s):: Luu, J., Johnsen, J. F., Passille, A. M. de, Rushen, J.
