Foraging efficiency, social status and body condition in group-living horses and ponies (2020)
Journal Article
Giles, S., Harris, P. A., Rands, S. A., & Nicol, C. J. (2020). Foraging efficiency, social status and body condition in group-living horses and ponies. PeerJ, https://doi.org/10.7717/peerj.10305

Individual animals experience different costs and benefits associated with group living, which may impact on their foraging efficiency in ways not yet well specified. This study investigated associations between social dominance, body condition and i... Read More about Foraging efficiency, social status and body condition in group-living horses and ponies.

There has been less attention devoted to the impact of human acti... Read More about Anthropogenic Threats to Wild Cetacean Welfare and a Tool to Inform Policy in This Area.

From Unpleasant to Unbearable - Why And How to Implement an Upper Limit to Pain And Other Forms of Suffering in Research with Animals (2020)
Journal Article
Olsson, I. A. S., Nicol, C. J., Niemi, S. M., & Sandøe, P. (2020). From Unpleasant to Unbearable - Why And How to Implement an Upper Limit to Pain And Other Forms of Suffering in Research with Animals. ILAR Journal, https://doi.org/10.1093/ilar/ilz018

The focus of this paper is the requirement that the use of live animals in experiments and in vivo assays should never be allowed if those uses involve severe suffering. This requirement was first implemented in Danish legislation, was later adopted...

The Ethics of Laying Hen Genetics (2019)
Journal Article

Despite societal concerns about the welfare of commercial laying hens, little attention has been paid to the welfare implications of the choices made by the genetics companies involved with their breeding. These choices regarding trait selection and... Read More about The Ethics of Laying Hen Genetics.

Light-based monitoring devices to assess range use by laying hens (2019)
Journal Article
Buijis, S., Nicol, C. J., Booth, F., Richards, G., & Tarlton, J. F. (2019). Light-based monitoring devices to assess range use by laying hens. animal, 14(4), 814-823. https://doi.org/10.1017/S1751731119002830

Access to an outdoor range has many potential benefits for laying hens but range use can be poor due to factors only partly understood. Techniques to monitor individual range use within commercial flocks are crucial to increase our understanding of t...

The aim of the study was to determine whether early access to elevated structures affects spatial navigational abilities. Ninety six day-old chicks were reared in 16 pens. Eight pens were provided with A-frame perches with an attached platform and a... Read More about The impact of early structural enrichment on spatial cognition in layer chicks.

The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition (2018)
Journal Article
Norman, K. I., Weeks, C. A., Pettersson, I. C., & Nicol, C. J. (2018). The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition. Applied Animal Behaviour Science, 208, 92-99. https://doi.org/10.1016/j.applanim.2018.08.007

In commercial situations, laying hens must negotiate levels to reach resources such as food, water and litter. Providing ramps in aviary systems reduces collisions and resultant keel bone fractures in adults. We investigated whether providing ramps d...

Examining affective structure in chickens: valence, intensity, persistence and generalization measured using a conditioned place preference test (2018)
Journal Article
Paul, E. S., Edgar, J. L., Caplen, G., & Nicol, C. J. (2018). Examining affective structure in chickens: valence, intensity, persistence and generalization measured using a conditioned place preference test. Applied Animal Behaviour Science, 207, 39-48. https://doi.org/10.1016/j.applanim.2018.07.007

When measuring animals’ valenced behavioural responses to stimuli, the Conditioned Place Preference (CPP) test goes a step further than many approach-based and avoidance-based tests by establishing whether a learned preference for, or aversion to, th...

Socially-mediated arousal and contagion within domestic chick broods (2018)
Journal Article
Edgar, J. L., & Nicol, C. J. (2018). Socially-mediated arousal and contagion within domestic chick broods. https://doi.org/10.1038/s41598-018-28923-8

Emotional contagion – an underpinning valenced feature of empathy – is made up of simpler, potentially dissociable social processes which can include socially-mediated arousal and behavioural/physiological contagion. Previous studies of emotional con... Read More about Socially-mediated arousal and contagion within domestic chick broods.

Re-direction of maternal behaviour in dairy cows (2017)
Journal Article
Mandel, R., & Nicol, C. J. (2017). Re-direction of maternal behaviour in dairy cows. Applied Animal Behaviour Science, 195, 24-31. https://doi.org/10.1016/j.applanim.2017.06.001

In the milk producing industry, most aspects of maternal behaviour are discouraged, but milk production is actively maintained in the absence of the calf. The process of milk let down, is mediated, at least partly, by oxytocin, which has been shown t... Read More about Re-direction of maternal behaviour in dairy cows.

Social buffering in a bird (2015)
Journal Article
Edgar, J., Held, S., Paul, E., Pettersson, I., L'Anson-Price, R., & Nicol, C. J. (2015). Social buffering in a bird. Animal Behaviour, 105, 11-19. https://doi.org/10.1016/j.anbehav.2015.04.007

The presence of a conspecific can ameliorate an individual's stress response. This social buffering is known to be widespread in social mammals but the capacity of birds to act as social buffers has not yet been determined. We previously demonstrated... Read More about Social buffering in a bird.

Elevated arousal at time of decision-making is not the arbiter of risk avoidance in chickens (2015)
Journal Article
Davies, A. C., Radford, A. N., Pettersson, I. C., Yang, F. P., & Nicol, C. J. (2015). Elevated arousal at time of decision-making is not the arbiter of risk avoidance in chickens. https://doi.org/10.1038/srep08200

The somatic marker hypothesis proposes that humans recall previously experienced physiological responses to aid decision-making under uncertainty. However, little is known about the mechanisms used by non-human animals to integrate risk perception wi...
