Contributor(s):: Garner, J. P., Meehan, C. L., Famula, T. R., Mench, J. A.
Stereotypies and psychogenic feather picking represent two distinct forms of abnormal behavior in parrots, with implications for welfare and owner relinquishment. While both behaviors are common in captive parrots, relatively little is known about the factors that may predispose a parrot to their...

Modelling the dynamic activity of broiler chickens in response to step-wise changes in light intensity
Contributor(s):: Kristensen, H. H., Aerts, J. M., Leroy, T., Wathes, C. M., Berckmans, D.
Controlling activity in broiler chickens may provide an inexpensive tool with the potential to improve broiler welfare by reducing lameness, reducing injuries during catching as well as increasing synchronisation within the flock. Despite much attention, no method has so far been able to control...

The behavioural and physiological reactions of farmed red deer to transport: effects of sex, group size, space allowance and vehicular motion
| Contributor(s):: Grigor, P. N., Goddard, P. J., Littlewood, C. A.
30 male and 30 female yearling red deer, comprising 8 single-sex groups of 5 or 10 animals, were loaded onto a livestock transporter for 3 h at a space allowance of 0.5 or 1 msuperscript 2/deer (males), or 0.4 or 0.8 msuperscript 2/deer (females). During this time deer were either transported or...

A note on effects of gender and time of day on the winter time-activity budget of adult ostriches ( Struthio camelus ) in a farming environment
| Contributor(s):: Deeming, D. C.
Male and female adult ostriches, maintained in 3 pairs and 6 trios on a commercial ostrich farm in Britain, were observed for five 10-min periods in the morning and afternoon during February 1997. Weather conditions included periods of rain, high winds, overcast days and bright sunny days, and...

Comparisons of damaging feather pecking and time budgets in male and female turkeys of a traditional breed and a genetically selected male line
| Contributor(s):: Busayi, R. M., Channing, C. E., Hocking, P. M.
Feather and skin pecking leading to feather loss and tissue damage is a welfare problem in commercial turkeys. A factorial experiment was designed to compare a line of unselected turkeys that previously did not exhibit this behaviour with a genetically selected male line with a propensity for...

Determination of sex differences in personality and trainability of yearling horses utilizing a handler questionnaire
| Contributor(s):: Duberstein, K. J., Gilkeson, J. A.
Very little scientific evidence exists to quantify differences in trainability and personality between sex of horses in spite of numerous industry stereotypes. It could be of great benefit to the horse industry to categorize personality differences and isolate strengths and weaknesses of each...

Factors influencing the behaviour and welfare of captive lion-tailed macaques in Indian zoos
| Contributor(s):: Avanti, Mallapur, Waran, N., Anindya, Sinha
A behavioural study was conducted on 47 lion-tailed macaques housed in 13 zoos across India. An ethogram was constructed and behavioural observations conducted using qualitative sampling ad libitum, focal animal sampling and instantaneous scans. Sampling was conducted only during the day when...

Genetic parameters and environmental effects which characterise the defence ability of the Belgian shepherd dog
| Contributor(s):: Courreau, J. F., Langlois, B.
The aim of the present study was to evaluate the heritability of defence capacity traits in the Belgian shepherd dog and to calculate the genetic correlations between traits and the role of particular environmental factors. The study used 15 772 competition results from defence dogs involving...

Grouping piglets by sex at weaning reduces aggressive behaviour
| Contributor(s):: Colson, V., Orgeur, P., Courboulay, V., Dantec, S., Foury, A., Morme, P.
The aim of this work was to reduce aggressive behaviour when piglets are grouped at weaning. The experiment assessed whether it is better to group piglets by sex at weaning or to mix them in male-female groups. Large White piglets were weaned at 28 days and assigned to 4 conditions, with 6 groups...

Suckling behaviour of Nelore, Gir and Caracu calves and their crosses
| Contributor(s):: Costa, M. J. R. P. da, Albuquerque, L. G., Eler, J. P., Silva, J. A. I. I. de V.
It is reasonable to assume that the knowledge of suckling behaviour contributes to optimal management and selection of beef cattle. However, there is little information about suckling behaviour of some beef cattle breeds. The aim of this study was to describe the suckling behaviour of two zebu...
