Effects of early maternal separation of lambs and rearing with minimal and maximal human contact on meat quality
Contributor(s):: Napolitano, F., Caroprese, M., Girolami, A., Marino, R., Muscio, A., Sevi, A.
The present study aims to assess the effect of gentling on behaviour and meat quality of lambs. Thirty-two Comisana lambs were divided into four groups of eight animals: ER (ewe reared), AR (artificially reared) and the corresponding gentled groups ERG and ARG. The provision of human contacts...

Colour preferences of domestic chicks in relation to food and water presentation
Contributor(s):: Roper, T. J., Marples, N. M.
The colour preferences of chicks presented with artificially coloured food (chick starter crumbs) and water were investigated. In experiment 1, 96 pairs of chicks received red, green or black food in the form of a small pile of crumbs placed on the floor of the test cage, or red, green or black...
Dairy cows prefer shade that offers greater protection against solar radiation in summer: shade use, behaviour, and body temperature
Contributor(s):: Schutz, K. E., Rogers, A. R., Cox, N. R., Tucker, C. B.
There is considerable evidence that shade is a valuable resource for cattle in summer, but less is known about the important design features of effective shade. The aim of this experiment was to investigate if lactating dairy cows have a preference for shade that offers greater protection against...
Dairy cows' use of colour cues to discriminate between people
Contributor(s):: Munksgaard, L., Passille, A. M. de, Rushen, J., Ladewig, J.
The role of the colour of overalls as a cue used by cows to discriminate between people was studied in 4 experiments using 66 Danish Friesian cows kept in tie-stalls. In all experiments, the average distance cows kept from the person was calculated during 1 min with the person standing in front...
Evaluation of an active transponder system to monitor spatial and temporal location of cattle within patches of a grazed sward
Contributor(s):: Swain, D. L., Wilson, L. A., Dickinson, J.
An active transponder system adapted for animal behaviour studies is described, and the potential of the system to facilitate patch scale monitoring of grazing cows is explored. A preliminary experiment examined the effect of presence and colour of loop aerial wires, on the activity of grazing...
Factors associated with the prevalence of stereotypic behaviour amongst Thoroughbred horses passing through auctioneer sales
Contributor(s):: Mills, D. S., Alston, R. D., Rogers, V., Longford, N. T.
The objective of this study was to evaluate whether sex, age and/or coat colour were associated with the occurrence of stereotypic behaviour in the horse and to assess whether the occurrence of one type of stereotypy in an individual was associated with the occurrence of another specific type of...
How do miniature pigs discriminate between people? Discrimination between people wearing coveralls of the same colour
Contributor(s):: Koba, Y., Tanida, H.
Seven experiments were conducted on 4 miniature pigs to determine: (1) whether the pigs can discriminate between people wearing the same coloured clothing and (2) what cues they rely on if they could discriminate. For 2 weeks before the experiments began, the pigs were conditioned in a Y-maze to...
How do miniature pigs discriminate between people? The effect of exchanging cues between a non-handler and their familiar handler on discrimination
During a 3-week handling period, six 8-week-old pigs were touched and fed raisins as a reward whenever they approached their handler, In subsequent training, the handlers and a non-handler wearing dark blue and white overalls, respectively, and wearing different eau de toilette fragrances sat at...

The ability of domestic hens to jump between horizontal perches: effects of light intensity and perch colour
Contributor(s):: Taylor, P. E., Scott, G. B., Rose, P.
Commercial non-cage housing systems for laying hens are kept at low light intensities to reduce the incidence of feather pecking. These low light intensity conditions may restrict the ability of hens to visually perceive important environmental features such as perches. This may have the...
Does balancing for color affect pigs' preference for different flavored tail-models?
Contributor(s):: Jankevicius, M. L., Widowski, T. M.
In previous work using rope flavored with various solutions as a model to study tail biting, pigs generally show a preference for the blood-flavored models compared to untreated models or models soaked in NaCl solutions or different fractions of blood. However, in these studies tail models were...
Object play in adult domestic cats: the roles of habituation and disinhibition
Contributor(s):: Hall, S. L., Bradshaw, J. W. S., Robinson, I. H.
We have investigated the role of habituation and disinhibition in the control of object (predatory) play by adult domestic cats Felis silvestris catus both with and without prior experience of hunting. We hypothesised that object play is terminated by rapid habituation to the sensory...
The effect of early colour preference and of a colour exposing procedure on the choice of nest colours in laying hens
Contributor(s):: Huber-Eicher, B.
It has been observed that hens at the start of lay show a strong preference for a limited number of nests, i.e. those at the corners and at the ends of rows. This leads to overcrowded nests and, as a consequence, to more aggression and an increase in cracked and mislaid eggs. This study aims to...
