  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. 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...
