The effects of witnessing managemental procedures during the light versus the dark phase of the light cycle on behaviour, performance and welfare of laboratory rats
Contributor(s):: Abou-Ismail, U. A., Mohamed, R. A., El-Kholya, S. Z.
Research has indicated that witnessing managemental procedures are stressful to laboratory rats. Yet there has been little investigation into whether the time of witnessing these procedures affects behaviour and welfare in these animals. Ninety-six rats, representing two batches, were used in...

Effects of floor-feeding and the presence of a foraging substrate on the behaviour and stress physiological response of individually housed gilts
Contributor(s):: Leeuw, J. A. de, Ekkel, E. D., Jongbloed, A. W., Verstegen, M. W. A.
Both restricted feeding and barren housing have a negative influence on sow welfare. The aim of this study was to test whether sows that have to search for their feed in a substrate on the floor show less stereotyped (and other abnormal) behaviour and have a lower physiological stress response....
The effects of surgical and chemical castration on intermale aggression, sexual behaviour and play behaviour in the male ferret ( Mustela putorius furo )
Contributor(s):: Vinke, C. M., Deijk, R. van, Houx, B. B., Schoemaker, N. J.
The ferret (Mustela putorius furo) has become an increasingly popular pet animal, yet little is known about their behaviour and welfare. Inter- and intra-specific aggression and the intense musky scent are the two main reasons why male ferrets are normally surgically castrated. However, it is...

Behavioural responses of heifers to ACTH injections
Contributor(s):: Negrao, J. A., Porcionato, M. A. de F., Passille, A. M. de, Rushen, J.
The objective of this study was to investigate behavioural changes in Holstein heifers caused by exogenous adrenocorticotropic hormone (ACTH) administration. Twelve 11-month-old heifers were submitted to either a single saline or ACTH injection and then the treatments were switched after 3 days...
The influence of pleasant and unpleasant handling and the provision of toys on the growth and behaviour of male pigs
Contributor(s):: Pearce, G. P., Paterson, A. M., Pearce, A. N.
This experiment investigated the influence of pleasant or unpleasant handling by humans on the growth, carcass composition, adrenal morphology and behaviour of male pigs, between 40 and 90 kg bodyweight, housed in groups of 8 in barren or enriched pens. Enriched pens were supplied with toys such...
Effects of weaning age on the behavioural and neuroendocrine development of piglets. (Special Issue: Early Weaning.)
Contributor(s):: Jarvis, S., Moinard, C., Robson, S. K., Sumner, B. E. H., Douglas, A. J., Seckl, J. R., Russell, J. A., Lawrence, A. B.
Adverse early life experiences can permanently "programme" increases in stress reactivity in adulthood. We investigated whether weaning, which involves maternal separation, at different ages, altered subsequent behaviour, physiology and neuroendocrine function in young pigs. The litters of twelve...
Evaluation of the effects of a socialization program in a prison on behavior and pituitary-adrenal hormone levels of shelter dogs
Contributor(s):: Hennessy, M. B., Morris, A., Linden, F.
This study examined outcomes of an ongoing socialization program for shelter dogs conducted at a local prison. Dogs residing at a Humane Society facility were assigned to either a "Control" or "Socialization" treatment. Dogs assigned to both treatments were administered a pretest at the Humane...
Some effects of repeated handling on stress responses in sheep
Contributor(s):: Hargreaves, A. L., Hutson, G. D.
Repeated exposure to a handling treatment was investigated as a possible method of reducing the stress response to shearing. Sheep were exposed to sham shearing (a procedure in which no wool is removed, but which otherwise resembles shearing) on 4 occasions at 2-week intervals. The peak cortisol...
Blood catecholamines in response to handling in normal and stress-susceptible swine
Contributor(s):: DeRoth, L., Vermette, L., Blouin, A., Lariviere, N.
Venous blood was collected from 23 porcine stress syndrome (PSS)-susceptible and 55 resistant 3-month-old Landrace pigs. Susceptibility to PSS was determined by the halothane test and resistance was confirmed by the halothane succinylcholine test, which were performed after the blood sampling...
Consequences of weaning piglets at 21 and 28 days on growth, behaviour and hormonal responses
Contributor(s):: Colson, V., Orgeur, P., Foury, A., Mormede, P.
A recent European Directive raised the minimum weaning age of piglets to 28 days, although weaning at 21 days is still allowed (but not necessarily practiced) in batch breeding conditions. The aim of the present study was to determine the consequences of weaning at 3 and 4 weeks on animal weight...
Effects of prenatal handling stress on adrenal weight and function and behaviour in novel situations in blue fox cubs ( Alopex lagopus )
Contributor(s):: Braastad, B. O., Osadchuk, L. V., Lund, G., Bakken, M.
This study investigated the effects of a 1-min daily handling stress given to farmed blue fox females in the last third of gestation on adrenal weight and function in male and female offspring and on behaviour in novel situations. In 10-day-old cubs (n=68), records were made of serum...
