  1. Nurturing your pet with nature - Part 2: Sensory and discovery experiences

    Contributor(s):: Rauh, R. M.

  2. Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?

    Contributor(s):: Burwell, A. K., Baldwin, A. L.

    In animal facilities, noises, often poorly controlled, occur over a wide range of frequencies and intensities. Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology, but it is not known how they affect the autonomic nervous system (ANS). This study...

  3. Noise in the animal shelter environment: building design and the effects of daily noise exposure

    Contributor(s):: Coppola, C. L., Enns, R. M., Grandin, T.

    Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological, and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise...

  4. Why do large dogs sound more aggressive to human listeners: acoustic bases of motivational misattributions

    Contributor(s):: Taylor, A. M., Reby, D., McComb, K.

    Previous research has highlighted that while human listeners are capable of estimating the body size of dogs using the acoustic components of their growls, they also rate growls from larger dogs as more being aggressive than growls from smaller dogs. The aim of this study was to investigate the...

  5. The response of beef cattle to noise during handling

    Contributor(s):: Waynert, D. F., Stookey, J. M., Schwartzkopf-Genswein, K. S., Watts, J. M., Waltz, C. S.

    59 yearling beef heifers (362+or-26 kg) were used in a study to evaluate their behavioural and physiological response to noises during a 1 min exposure. In Trial 1, 29 heifers that were naive to the treatments were assigned to either prerecorded handling noise (Noise, n=14) composed of humans...

  6. Development of a behavioural test of sensory responsiveness in the growing pig

    Contributor(s):: Hutson, G. D., Ambrose, T. J., Barnett, J. L., Tilbrook, A. J.

    The responses of individual growing pigs to 60 stimuli from 5 sensory categories were evaluated as an initial step in developing a behavioural measure of welfare. Pigs were exposed to the stimuli in a test pen after being trained to eat from a food box adjacent to a stimulus presentation box. The...

  7. Social eavesdropping in the domestic dog

    Contributor(s):: Marshall-Pescini, S., Passalacqua, C., Ferrario, A., Valsecchi, P., Prato-Previde, E.

    Eavesdropping on third-party interactions has been observed in a number of species and is considered an important source of information in decision-making processes relating to fighting and mate choice. Human beings, however, use publicly available information flexibly in many different contexts...

  8. Behavioural and physiological responses of pigs to sound

    Contributor(s):: Talling, J. C., Waran, N. K., Wathes, C. M., Lines, J. A.

    Eight piglets were exposed to artificially generated sounds, nominal intensities of 85 or 97 dB(Lin), and frequencies of 500 or 8000 Hz for 15 min during a 1-h experimental period. In a 2nd experiment, 8 piglets were exposed to 20 min of farm sounds (Leq 80 dB), transport sounds (Leq 83 dB),...

  9. Recorded sounds associated with feeding did not affect feeding behavior of lambs

    Contributor(s):: Tanida, H., Hohenboken, W. D., Swanson, L. V.

  10. Sound avoidance by domestic pigs depends upon characteristics of the signal

    Contributor(s):: Talling, J. C., Waran, N. K., Wathes, C. M., Lines, J. A.

    Two groups of 12 pigs, weighing 25 kg, were individually exposed to a test sound in a modified unsignalled one-way avoidance procedure. The test sound for the first group was a recording from an animal transporter played at 84 dB(Lin), with a rise time of 2 s (uniform). For the second group,...

  11. A preliminary study of the effects of ecologically relevant sounds on the behaviour of captive lowland gorillas

    Contributor(s):: Ogden, J. J., Lindburg, D. G., Maple, T. L.

  12. The impact of acoustical secondary reinforcement during shape discrimination learning of dwarf goats ( Capra hircus )

    Contributor(s):: Langbein, J., Siebert, K., Nuernberg, G., Manteuffel, G.

    The use of secondary reinforcement is widely accepted to support operant learning in animals. In farm animals, however, the efficacy of secondary reinforcement has up to now been studied systematically only in horses ("clicker training"), and the results are controversial. We investigated the...

  13. The response of sows to novel visual, olfactory, auditory and tactile stimuli

    Contributor(s):: Hutson, G. D., Dickenson, L. G., Wilkinson, J. L., Luxford, B. G.

    The response of sows to 20 stimuli from 5 sensory categories were evaluated with the aim of selecting one stimulus from each category as a test of general environmental responsiveness. The visual stimuli evaluated were a novel rod, a hanging ball, a moving chime and an umbrella. The olfactory...

  14. Behavioural responses of sows and piglets from two genotypes to recorded nursing grunts played throughout lactation

    Contributor(s):: Farmer, C., Robert, S.

    The impact of playbacks of recorded sow nursing grunts on the development of nursing behaviour in sows from two genotypes was studied. Yorkshire x Landrace (YL; n=16) and 25% Meishan (MH; n=16) gilts were equally divided in two groups: (1) no playback, and (2) playbacks of recorded sow nursing...

  15. Multifactorial testing of enrichment criteria: pigs 'demand' hygiene and destructibility more than sound

    Contributor(s):: Bracke, M. B. M.

    To validate (further) a semantic model called RICHPIG, which was designed to assess enrichment materials for pigs, a study was conducted to examine the importance of three assessment criteria, namely destructibility, hygiene and sound. These material properties were studied using a specially...

  16. Responses of horses to novel visual, olfactory and auditory stimuli

    Contributor(s):: Christensen, J. W., Keeling, L. J., Nielsen, B. L.

    Responses of horses towards fear-eliciting stimuli can have important consequences for both human and horse safety. This experiment was designed to investigate behavioural and heart rate (HR) responses of horses to novel visual, auditory and olfactory stimuli. Twenty-four 2-year-old, previously...

  17. Vocal individuality during suckling in the intensively housed domestic pig

    Contributor(s):: Blackshaw, J. K., Jones, D. N., Thomas, F. J.

    Nursing vocalizations, signalling lactation, were studied in 10 Large White x Landrace sows (parity 1-8; housed in the minimal disease piggery at the Veterinary Science Farm, University of Queensland, Australia). Nursing grunts were characterized using Canary 1.2 software to produce a...

  18. The influence of auditory stimulation on the behaviour of dogs housed in a rescue shelter

    Contributor(s):: Wells, D. L., Graham, L., Hepper, P. G.

    This study explored the influence of five types of auditory stimulation (human conversation, classical music, heavy metal music, pop music and a control) on the behaviour of 50 dogs housed in a rescue shelter in the UK [date not given]. The dogs were exposed to each type of auditory stimulation...
