Are Baby Animals Less Appetizing? Tenderness toward Baby Animals and Appetite for Meat
Contributor(s):: Piazza, Jared, McLatchie, Neil, Olesen, Cecilie
Three studies investigated whether thoughts and feelings generated by baby animals might oppose appetite for meat. A prestudy established babyness as an important factor predicting moral concern for farmed animals. Study 1 showed that presenting images of baby animals, versus adult animals, as...
Consistency of individual variation in feeding behaviour and its relationship with performance traits in Nile tilapia Oreochromis niloticus
Contributor(s):: Martins, Catarina I. M., Conceição, Luis E. C., Schrama, Johan W.
Feed intake is commonly used as one of the most important performance indicators in fish. However, very little is known about the behavioural processes involved in ingesting food such as meal duration, feeding frequency and latency to start eating. This study aims at the characterization of...

On-farm evaluation of the Salmon Welfare Index Model (SWIM 1.0): theoretical and practical considerations
| Contributor(s):: Folkedal, O., Pettersen, J. M., Bracke, M., Stien, L. H., Nilsson, J., Martins, C., Breck, O., Midtlyng, P. J., Kristiansen, T.
The present study investigated the operational feasibility of the recently developed Salmon Welfare Index Model (SWIM 1.0) designed for Atlantic salmon ( Salmo salar L) in production cages. Ten salmon farms containing spring smolts were visited twice, first between May and June the first year in...
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 Some riding horses display 'withdrawn' states of inactivity and low responsiveness that resemble the reduced engagement with the environment shown by certain depressed...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...

Evoking trust in the nutrition counselor: why should we be trusted?
| Contributor(s):: Gingras, J.
The virtue of trust is often spoken of as central to the work of dietitians working in nutrition counseling, especially in the context of disordered eating/eating disorders nutrition therapy. Indeed, dietitians are purported to be the most trusted source of information on nutrition and food by...
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 amount of milk, milk flow and access to a rubber teat on cross-sucking and non-nutritive sucking in dairy calves. (Special issue: Suckling)
| Contributor(s):: Jung, J., Lidfors, L.
The aim of this study was to test the effects of different amounts of milk, rate of milk flow, and access to a teat after milk intake on non-nutritive sucking on an empty teat and on cross-sucking on other calves in Bos taurus dairy calves. An additional aim was to test if calves prefer to...
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...
