Behavioral and physiological correlates of stress in laboratory cats
Contributor(s):: Carlstead, K., Brown, J. L., Strawn, W.
Sixteen domestic cats were used to investigate the pituitary-adrenal, pituitary-gonadal and behavioural consequences of an unpredictable handling and husbandry routine. After a 10-day baseline period of standard laboratory procedures, 8 cats ('stressed cats', STR) were subjected to a 21-day...
Behaviour of laying hens during induced moulting in three different production systems
Contributor(s):: Aggrey, S. E., Kroetzl, H., Foelsch, D. W.
This work is a critical investigation of how methods of moulting are practiced by farmers. Dekalb hens were fasted with a reduced photoperiod to induce moult and hence lengthen the total egg laying period in three housing systems, namely wire floor, multifloor (globovolg) and battery cages. The...
Behaviour of restricted-fed broiler breeders in relation to pharmacological manipulation of dopamine and opioid receptor subtypes

Behavioural and adrenocortical responses of dairy cows toward novel food: effects of food deprivation, milking frequency and energy density in the daily ration
Contributor(s):: Herskin, M. S., Munksgaard, L., Kristensen, A. M.
Effects of metabolic load and 12 h of food deprivation on the behavioural and physiological responses toward novel food were examined in dairy cows provided with 4 kg of carrots as novel food and observed using video for the initial 10 min. In Experiment I, effects of 12 h of food deprivation...
Behavioural consequences of visual deprivation occurring at hatch or in the early life of chickens
Contributor(s):: Hocking, P. M., Haldane, K. A., Davidson, E. M., Sandoe, P., Kristensen, H. H.
The development of behaviour in a line of chickens that are born sighted ( rdd) but turn blind after hatching was compared with a line that is blind at hatch ( beg) and with sighted White Leghorn controls (WL) to test the hypothesis that birds that become blind later in their life will show...

Bones as enrichment for farmed blue foxes ( Vulpes lagopus ): interaction with the bones and preference for a cage with the bones
Contributor(s):: Koistinen, T., Turunen, A., Kiviniemi, V., Ahola, L., Mononen, J.
Animal welfare regulations (e.g. Recommendations of European Convention) state that farmed foxes need to be provided with an activity object, though the material or shape of the object is not specified. We aimed to evaluate the properties of bones as an activity object for farmed blue foxes...
De-arousal properties of stereotyped behaviour: evidence from pituitary-adrenal correlates in pigs
Contributor(s):: Dantzer, R., Mormede, P.
Behavioural and pituitary--adrenal responses of food-deprived pigs, submitted to an intermittent food delivery schedule repeated over several weeks, were investigated. All animals reliably displayed stereotyped activites, in the form of repeated chain pulling, during the interval between food...
Deprivation of straw bedding alters PGF<sub>2 alpha </sub>-induced nesting behaviour in female pigs
Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Gilbert, C. L.
Sows are highly motivated to build a maternal nest on the day preceding parturition. A model for nest building has been established in pigs, in which exogenously administered prostaglandin F2 alpha (PGF2 alpha ) may be used to elicit nesting behaviour in cyclic, pseudopregnant and pregnant pigs....
Discriminating among novel foods: effects of energy provision on preferences of lambs for poor-quality foods
Contributor(s):: Villalba, J. J., Provenza, F. D.
A study was conducted to better understand how lambs discriminate among novel foods based on flavour and post-ingestive effects. The manner in which temporal sequence of food ingestion and post-ingestive feedback affected preference when lambs were fed flavoured wheat straw (a poorly nutritious...
Diurnal and individual variation in behaviour of restricted-fed broiler breeders

Do different levels of moderate feed deprivation in dairy cows affect feeding motivation?
Contributor(s):: Schutz, K., Davison, D., Matthews, L.
Dairy cows grazed on pasture are likely to experience seasonal fluctuations in both the quantity and quality of forage available. In order to better understand how the variation in feed supply influences animal welfare, we need to understand the degree of hunger experienced during various levels...
Effect of pre-weaning temporary isolation within different age periods on the early post-weaning behaviour of juvenile lambs
Contributor(s):: Simitzis, Panagiotis, Petrou, Miria, Demiris, Nikos, Deligeorgis, Stelios
Temporary maternal separation is a stressful situation typical under modern husbandry practices and may have an undesirable impact on lamb welfare. However, at present there is insufficient evidence on temporary maternal separation effects on the behaviour of juvenile lambs. The aim of the...
Effects of developmental history on the behavioural responses of European starlings ( Sturnus vulgaris) to laboratory husbandry

Effects of food on drinking behaviour of growing pigs
Contributor(s):: Yang, T. S., Howard, B., Macfarlane, W. V.
Growing pigs do not show, in their watering behaviour, a direct response to systemic water requirements. At environmental temperatures around 25 deg C, growing pigs have a daily water turnover (measured by tritiated water) of 120-130 ml/kg or about 250 ml/kg0.82 when fed dry pellets at the rate...

Environmental enrichment and cognitive complexity in reptiles and amphibians: Concepts, review, and implications for captive populations
Contributor(s):: Burghardt, Gordon M.
Reptiles and amphibians have been neglected in research on cognition, emotions, sociality, need for enriched and stimulating environments, and other topics that have been greatly emphasized in work on mammals and birds. This is also evident in the historic lack of enriching captive environments...

Eye white may indicate emotional state on a frustration-contentedness axis in dairy cows
Contributor(s):: Sandem, A. I., Braastad, B. O., Boe, K. E.
Research on welfare indicators has focused primarily on indicators of poor welfare, but there is also a need for indicators that can cover the range from good to poor welfare. The aim of this experiment was to compare behaviour elements in dairy cows shown in response to a frustrative situation...
