A method for measuring the aversiveness of sounds to domestic hens
Contributor(s):: McAdie, T. M., Foster, T. M., Temple, W., Matthews, L. R.
Six hens' key-pecking at each of 2 simultaneously available perspex discs (keys) was maintained by intermittent access to wheat. Over a series of conditions one of 4 sounds (music, water-hose, poultry and train), at a range of decibel levels (90-100 dB(A)) was relayed to the experimental chamber...
A method for the economic valuation of animal welfare benefits using a single welfare score
Contributor(s):: Bennett, R., Kehlbacher, A., Balcombe, K.
A model to quantify the anticipatory response in cats
Contributor(s):: Tami, G., Martorell, A., Torre, C., Compagnucci, M., Manteca, X.
The aim of this paper was to develop a protocol to study the anticipatory response in cats as a measure of welfare. Seven experimental cats were trained in a classical conditioning paradigm to associate a sound with food arrival, while sound and food were presented without contingency in four...
A modified HET-CAM approach for biocompatibility testing of medical devices
Contributor(s):: Eder, C., Falkner, E., Mickel, M., Chiari-Grisar, C., Appl, H., Schoffl, H., Nehrer, S., Losert, U. M.
The implantation of new biomedical devices into living animals without any previous toxicity or biocompatibility evaluation is possible under current legislation. The HET-CAM (Hen Egg Test-Chorionallantoic Membrane) test offers a partially immunodeficient, borderline in vitro/in vivo test system...
A mouse is not just a mouse
Contributor(s):: Sluyter, F., Oortmerssen, G. A. van
In this review, we describe the existence and consequences of subspecific and individual variation in the genetic make-up of house mice. The purpose is to illustrate forms of variation that are often neglected in discussions about animal care and experimental design. Different inbred mouse...
A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...
A neuropsychological and evolutionary approach to animal consciousness and animal suffering
Contributor(s):: Bermond, B.
A new format for learning about farm animal welfare. (Special Issue: Animal welfare in a broad perspective. Papers from the Nordic Network of Agriculture and Food Ethics.)
Contributor(s):: Algers, A., Lindstrom, B., Pajor, E. A.
Farm animal welfare is a knowledge domain that can be regarded as a model for new ways of organizing learning and making higher education more responsive to the needs of society. Global concern for animal welfare has resulted in a great demand for knowledge. As a complement to traditional...
A new framework for the assessment of animal welfare: integrating existing knowledge from a practical ethics perspective. (Animals and their welfare)
Contributor(s):: Aerts, S., Lips, D., Spencer, S., Decuypere, E., Tavernier, J. de
When making an assessment of animal welfare, it is important to take environmental (housing) or animal-based parameters into account. An alternative approach is to focus on the behaviour and appearance of the animal, without making actual measurements or quantifying. None of these tell the whole...
A new method to measure behavioural activity levels in dairy cows
Contributor(s):: Muller, R., Schrader, L.
Changes in the behavioural activity of farm animals are widely used as an indicator for the assessment of animal welfare. In this study on dairy cattle we validated a new method for automatic 24 h recording of behavioural activity, the ActiwatchReg. activity monitoring system (AMS). The AMS is a...
A non-intrusive method of assessing plumage condition in commercial flocks of laying hens
Contributor(s):: Bright, A., Jones, T. A., Dawkins, M. S.
A non-invasive system for remotely monitoring heart rate in free-ranging ungulates
Contributor(s):: Gedir, J. V.
A new, external non-invasive telemetric heart rate (HR) monitoring system was evaluated on 8 wapiti (Cervus elaphus canadensis), yearlings in July and August 1996. The assembly consisted of a leather girth strap, onto which a HR transmitter and a customized carriage bolt electrode system were...
A nonnatural head-neck position ( Rollkur ) during training results in less acute stress in elite, trained, dressage horses
Contributor(s):: Breda, E. van
This study measured parameters of stress in recreational, trained horses (REC; n=7) and elite (International Grand Prix level) trained, dressage horses (DRES; n=5). The training of the DRES horses uses an unnatural head-neck position (Rollkur), whereas in the REC horses such training techniques...
A note on a behavioural indicator of satisfaction in stabled horses
Contributor(s):: Ninomiya, S., Sato, S., Kusunose, R., Mitumasu, T., Obara, Y.
We observed the behaviour of six stabled horses (stallions n=3; geldings n=3) in an attempt to identify behavioural measures of eating satisfaction. The horses were required to perform an operant response (pressing a button with the muzzle) in order to access a food reward in an experimental box...
A note on a quantitative genetic approach for modelling of differentiation tasks
Contributor(s):: Dietl, G., Nurnberg, G., Reinsch, N.
Learning capacities and cognitive abilities of farm animals will become more important and they will have an impact on animal welfare and productivity. Scientific examinations of these aspects presuppose genetic models. This paper presents an approach for modelling differentiation tasks in animal...
A note on averting goats to a toxic but palatable plant, Leucaena leucocephala
Contributor(s):: Gorniak, S. L., Pfister, J. A., Lanzonia, E. C., Raspantini, E. R.
Conditioned taste aversions are a useful tool to reduce livestock consumption of toxic plants. The forage legume Leucaena leucocephala (leucaena) is both toxic and palatable. The objective of this study was to determine if goats could be aversively conditioned to avoid leucaena. Adult and...
A note on behaviour of poultry exposed to increasing carbon dioxide concentrations
Contributor(s):: Gerritzen, M., Lambooij, B., Reimert, H., Stegeman, A., Spruijt, B.
Killing poultry by means of whole house gassing with carbon dioxide (CO2) is an important tool in disease control. The behaviour of ducks, broilers, laying hens and turkeys was observed to assess differences in susceptibility between species and to assess animal welfare implications following...
A note on comparative enclosure facility usage by wild and captive-born capybaras ( Hydrochaerus hydrochaeris )
Contributor(s):: Nogueira, S. S. C., Bernardi, L. G., Nogueira Filho, S. L. G.
This study compared the use of the enclosure facilities (sheltered area, water-tank and exercise area) by wild versus captive-born capybaras. A total of 44 adult capybaras were kept in eight groups: four groups of animals born in the wild and caught as adults and four groups of those born and...
A note on enrichment for captive lion-tailed macaques ( Macaca silenus )
Contributor(s):: Mallapur, A., Waran, N., Anindya, Sinha
Two enrichment techniques were devised with the aim of reducing stress and improving welfare for captive lion-tailed macaques in an Indian zoo. In Study A, a log, cotton ropes and a feeding basket were added to the enclosures in different combinations to provide structural and feeding enrichment...
