Evaluation of an open source method for calculating physical activity in dogs from harness and collar based sensors
| Contributor(s):: Carri Westgarth, C. Ladha
Background: The ability to make objective measurements of physical activity in dogs has both clinical and research applications. Accelerometers offer a non-intrusive and convenient solution. Of the commercialy available sensors, measurements are commonly given in manufacturer bespoke units and...
Locomotor activity of dairy cows in relation to season and lactation
| Contributor(s):: Brzozowska, Anna, Łukaszewicz, Marek, Sender, Grażyna, Kolasińska, Dorota, Oprządek, Jolanta
All systems recording activity of cattle measure it independently of environmental and animal factors. Such recordings may hide differences in activity caused by extraneous interferences or may be inaccurately interpreted. The information produced by sensors could be more accurate, if behaviour...
Lying patterns of high producing healthy dairy cows after calving in commercial herds as affected by age, environmental conditions and production
| Contributor(s):: Steensels, Machteld, Bahr, Claudia, Berckmans, Daniel, Halachmi, Ilan, Antler, Aharon, Maltz, Ephraim
An animal expresses its physiological and well-being status by its behaviour. Changes in behaviour can be associated with health, production or well-being problems and therefore with the profitability of the farm. The objectives of the present study were to analyse lying patterns of healthy cows,...
Associations between precision sensor data with productivity, health and welfare indicator traits in native black and white dual-purpose cattle under grazing conditions
| Contributor(s):: Jaeger, Maria, Brügemann, Kerstin, Brandt, Horst, König, Sven
The aim of the study was to analyse the relationships between conventional production as well as subjectively scored welfare assessment traits with longitudinal sensor measurements (i.e., behavioural activity traits) of dual-purpose cattle kept in grazing systems. Such aim implies getting...

Problems at the human-horse interface and prospects for smart textile solutions
| Contributor(s):: McGreevy, P. D., Sundin, M., Karlsteen, M., Berglin, L., Ternstrom, J., Hawson, L., Richardsson, H., McLean, A. N.
The significant potential for so-called "smart textiles" in the design of the next generation of devices that measure pressure, tension, moisture, and heat at the human-horse interface is discussed in this article. Research techniques from theoretical and experimental physics laboratories,...

Are cows more likely to lie down the longer they stand?
| Contributor(s):: Tolkamp, B. J., Haskell, M. J., Langford, F. M., Roberts, D. J., Morgan, C. A.
Information on (changes in) standing and lying behaviour of cows can be used for oestrus detection, early diagnosis of disorders and to evaluate welfare consequences of changes in housing and management. Data sets on lying and standing behaviour were collected from cows with IceTagTM sensors...
Validation of an automatic system to detect position changes in puerperal sows
| Contributor(s):: Mainau, E., Dalmau, A., Ruiz-de-la-Torre, J. L., Manteca, X.
Piglet crushing by the sow is one of the main causes of piglet mortality during the first 48 h after birth. The frequency of position changes may be partially related to the pain caused by farrowing. The aim of this study was to develop and validate an automatic system to register position...
An automatic system to monitor lying, standing and walking behaviour of grazing animals
| Contributor(s):: Champion, R. A., Rutter, S. M., Penning, P. D.
Sensors incorporating mercury tilt switches were used to measure the lying, standing and walking behaviour of grazing cattle and sheep. The lying/standing sensor was suspended below the animal, whilst the walking sensor was fitted to the shin of the animal's foreleg. Both switches gave a...
Effects of animal/feeding-place ratio on the behaviour and performance of fattening pigs fed via sensor-controlled liquid feeding
| Contributor(s):: Rasmussen, D. K., Weber, R., Wechsler, B.
Sensor feeding is a liquid feeding system for fattening pigs that is run with a restricted animal/feeding-place ratio (AFR). Feeding occurs at specific periods, so that the trough is left empty in-between. Therefore, it must be regarded as an ad libitum feeding system. The aim of the present...
The somatic sensory system
| Contributor(s):: Kamerling, S. G.
The somatic sensory system provides information on bodily sensations. The status of an animal's internal and external environment is detected and interpreted by this system. Specialized receptors "transduce" the sensations of touch, pressure, temperature, and pain. Sensory impulses are...
