Investigating anhedonia in a non-conventional species: do some riding horses Equus caballus display symptoms of depression?
Contributor(s):: Fureix, C., Beaulieu, C., Argaud, S., Rochais, C., Quinton, M., Henry, S., Hausberger, M., Mason, G.
Investigating depression-like conditions in animals is methodologically challenging, but potentially important for welfare. Some riding horses display 'withdrawn' states of inactivity and low responsiveness that resemble the reduced engagement with the environment shown by certain depressed...
Nutritional and behavioral effects of gorge and fast feeding in captive lions
Contributor(s):: Altman, J. D., Gross, K. L., Lowry, S. R.
Nonhuman animals in captivity manifest behaviors and physiological conditions that are not common in the wild. Lions in captivity face problems of obesity, inactivity, and stereotypy. To mediate common problems of captive lions, this study implemented a gorge and fast feeding schedule that better...
Positive reinforcement training moderates only high levels of abnormal behavior in singly housed rhesus macaques
Contributor(s):: Baker, K. C., Bloomsmith, M., Neu, K., Griffis, C., Maloney, M., Oettinger, B., Schoof, V. A. M., Martinez, M.
This study evaluated the application of positive reinforcement training (PRT) as an intervention for abnormal behaviors in singly housed laboratory rhesus macaques at 2 large primate facilities. Training involved basic control behaviors and body-part presentation. The study compared baseline...
Effect of milkflow rate and presence of a floating nipple on abnormal sucking between dairy calves. (Special issue: Suckling)
Contributor(s):: Loberg, J., Lidfors, L.
The aim of this study was to investigate if access to an artificial teat, compared with an open bucket, would decrease abnormal sucking in calves held in pairs, and if the calves would perform less abnormal sucking if they spent more time drinking or sucking milk. Sixteen calves of Swedish Red...
Effects of qualitative and quantitative food restriction treatments on feeding motivational state and general activity level of growing broiler breeders
Contributor(s):: Savory, C. J., Lariviere, J. M.
Growing broiler breeder chickens are fed restricted rations to limit body weight at sexual maturity. This experiment tested a proposal (Brouns, F. et al. Applied Animal Behaviour Sciience (1994) 39, 215-223.) that feeding motivation is reduced by using qualitative rather than quantitative food...
Reduction in cross-sucking in calves by the use of a modified automatic teat feeder. (Special issue: Suckling)
Contributor(s):: Weber, R., Wechsler, B.
Cross-sucking may be a problem in group-housed calves fed by automatic teat feeders. In the present study, the behaviour of calves fed by a conventional feeder with an open feeding stall (n=15 calves) was compared with the behaviour of calves fed by a modified feeder, which closes in the rear...
Sucking motivation and related problems in calves. (Special issue: Suckling)
Contributor(s):: Passille, A. M. de
Because the survival of young mammals depends on sucking success, it is assumed that sucking motivation must be strong and that sucking deprivation would result in frustration, which could have a negative impact on the animals' welfare. This concern, as well as that regarding cross-sucking...
Do broiler chicks have a cognitive representation of food quality? Appetitive, behavioural and ingestive responses to a change in diet quality
Contributor(s):: Haskell, M. J., Vilarino, M., Savina, M., Atamna, J., Picard, M.
In order to understand more about food recognition and rejection, the aim of this experiment was to determine whether cognitive processes are involved. 16 groups of 4 broiler chicks were used, and were fed a low quality diet in their home pens. The groups of chicks were trained to run a winding...
A note on changes in ingestive behaviour of sheep following shearing
Contributor(s):: Arnold, G. W.
The grazing behaviour and herbage intake of sheep grazing at 4 stocking rates were recorded before and after shearing in winter. Following shearing, grazing time was reduced but intake of OM/h increased at all stocking rates even though the amount of feed available was very low at the highest...

Responses of farmed silver foxes ( Vulpes vulpes ) to excessive food availability: implications for using food as a yardstick resource in motivation tests
Contributor(s):: Hovland, A. L., Mason, G., Ahlstrom, O., Bakken, M.
Food is frequently used as a 'yardstick' in operant experiments. However, previous work on silver foxes had suggested that how food is presented can affect how they respond to it, with excess food leading to variable consumption rates, and cages containing food being avoided over control cages...
Contributor(s):: Forbes, J. M.
This review deals with an animal's ability to sense foods in the environment up to the point of swallowing (using vision, olfaction, taste, texture, position and palatability), i.e., where awareness of food is clearly conscious. Then the consequences of eating at the levels of the digestive...
The effect of early environment on neophobia in orange-winged Amazon parrots ( Amazona amazonica )
Contributor(s):: Fox, R. A., Millam, J. R.
Early experience is often a significant factor in shaping animals' later behaviour. Early maternal separation is associated with negative behavioral outcomes, such as increased fearfulness in rats, while higher levels of maternal grooming during the neonatal period are associated with decreased...
Assessment of hunger in growing broiler breeders in relation to a commercial restricted feeding programme
Contributor(s):: Savory, C. J., Maros, K., Rutter, S. M.
From 2 weeks old female broiler breeder chickens were restricted-fed on a commercial diet (R), twice that amount (2R), or ad libitum (AL). Motivation to eat in R and 2R birds was compared every third week with that of AL birds subjected to 3 to 72-h feed deprivation. AL and 2R birds grew 3 and 2...
