Understanding Animal Detection of Precursor Earthquake Sounds
Contributor(s):: Michael Garstang, Michael C. Kelley
We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using the...

Noise exposure, music, and animals in the laboratory: a commentary based on Laboratory Animal Refinement and Enrichment Forum (LAREF) discussions
Contributor(s):: Patterson-Kane, E. G., Farnworth, M. J.
The effects of noise, in general, and music, in particular, on the behavior and welfare of animals in the laboratory deserve a great deal of empirical study. However, many laboratories must develop their current practices on the basis of sparse and conflicting data. With this commentary we seek...
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...

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

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

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...
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...
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...
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...
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...
Sound stimuli to enhance ingestive behaviour of young turkeys
Contributor(s):: Bate, L. A.
A study was conducted to establish whether auditory stimulation in the form of pre-taped maternal vocalizations would influence initial feeding behaviour in newly hatched poults. For the purposes of the study control birds (Group C) were raised under simulated commercial conditions. Other birds...
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...
