The effects of high and low rates of food reinforcement on the behaviour of pigs (1996)
Journal Article
Young, R., & Lawrence, A. (1996). The effects of high and low rates of food reinforcement on the behaviour of pigs. Applied Animal Behaviour Science, 49(4), 365-374. https://doi.org/10.1016/0168-1591%2896%2901052-0

The expression of one behaviour by an animal limits the amount of time available to express other behaviours. In this experiment the amount of time animals had to forage was manipulated by decreasing the rate of food reinforcement available from a fo...

The effect of a moving bait on the behaviour of captive cheetahs (Acinonyx jubatus) (1996)
Journal Article
Williams, B., Waran, N., Carruthers, J., & Young, R. (1996). The effect of a moving bait on the behaviour of captive cheetahs (Acinonyx jubatus). Animal Welfare Journal, 5(3), 271-281. https://doi.org/10.1017/S0962728600018856

Members of the cat family are highly motivated to hunt, but in captivity are unable to do so for a variety of reasons. This inability to hunt may reduce their welfare. In this study we used a moving bait to stimulate and release hunting motivation in... Read More about The effect of a moving bait on the behaviour of captive cheetahs (Acinonyx jubatus).

The effect of a foraging device (a modified ‘Edinburgh Foodball’) on the behaviour of the stabled horse (1996)
Journal Article
Winskill, L., Waran, N., & Young, R. (1996). The effect of a foraging device (a modified ‘Edinburgh Foodball’) on the behaviour of the stabled horse. Applied Animal Behaviour Science, 48(1-2), 25-35. https://doi.org/10.1016/0168-1591%2895%2901021-1

Horses that are stabled under confined conditions may develop stereotypies (e.g. stall-walking), which may be caused by the inability of horses to express foraging behaviour. The objective of this study was to determine whether horses will use a fora...

On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator, Using the Giraffe (Glraffa Camelopardalis) as a Model (1996)
Journal Article
Veasey, J., Waran, N., & Young, R. (1996). On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator, Using the Giraffe (Glraffa Camelopardalis) as a Model. Animal Welfare Journal, 5(2), 139-153. https://doi.org/10.1017/S0962728600018571

To assess the validity of using wild behavioural data as a welfare indicator for zoo animals, the time budgets of 19 captive giraffe (Giraffa camelopardalis), from four zoos were compared with the time budgets of wild giraffe from Hwange National Par...

Assessment of motivation in the lizard, Chalcides ocellatus (1996)
Journal Article
Skelton, T., Waran, N., & Young, R. (1996). Assessment of motivation in the lizard, Chalcides ocellatus. Animal Welfare Journal, 5(1), 63-69. https://doi.org/10.1017/S0962728600018340

The purpose of this study was to assess whether running an alleyway can be used to measure the motivation of lizards. Six, eyed skinks, Chalcides ocellatus, were trained to run an alleyway to reach sand in which to hide. Each skink was deprived of sa...

On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator (1996)
Journal Article
Veasey, J. S., Waran, N. K., & Young, R. J. (1996). On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator. Animal Welfare Journal, 5(1), 13-24. https://doi.org/10.1017/s0962728600018297

It is commonly assumed that animals suffer if they cannot perform behaviours seen in wild conspecifics. Although comparisons with the behaviour of wild conspecifics are a popular method of assessing the welfare of captive animals, their validity has...

The effect of a foraging device (The ‘Edinburgh Foodball’) on the behaviour of pigs (1994)
Journal Article
Young, R., Carruthers, J., & Lawrence, A. (1994). The effect of a foraging device (The ‘Edinburgh Foodball’) on the behaviour of pigs. Applied Animal Behaviour Science, 39(3-4), 237-247. https://doi.org/10.1016/0168-1591%2894%2990159-7

Sows housed under conditions of food and physical restriction often perform behaviours indicative of poor welfare (e.g. repetitive chain chewing), one cause of which may be the inability of sows to express foraging behaviour under confined conditions...

Feeding behaviour of pigs in groups monitored by a computerized feeding system (1994)
Journal Article
Young, R., & Lawrence, A. (1994). Feeding behaviour of pigs in groups monitored by a computerized feeding system. Animal Science, 58(1), 145-152. https://doi.org/10.1017/S0003356100007182

Electronic feeding systems for progeny testing pigs, allow selection to occur under conditions found on commercial farms. This paper reports on the feeding behaviour of six groups of 10 pigs, balanced for sex and initial body weight (mean starting an...

Risk-sensitive foraging in bitterlings Rhodeus sericus: effects of food requirement and breeding site quality (1990)
Journal Article
Young, R., Clayton, H., & Barnard, C. (1990). Risk-sensitive foraging in bitterlings Rhodeus sericus: effects of food requirement and breeding site quality. Animal Behaviour, 40(2), 288-297. https://doi.org/10.1016/S0003-3472%2805%2980923-6

Risk-sensitive foraging preferences in bitterlings were examined in relation to changing food deprivation and intake relative to estimated requirement. When running above estimated requirement and presented with a choice of constant and variable feed...
