Eye white may indicate emotional state on a frustration-contentedness axis in dairy cows

Research on welfare indicators has focused primarily on indicators of poor welfare, but there is also a need for indicators that can cover the range from good to poor welfare. The aim of this experiment was to compare behaviour elements in dairy cows shown in response to a frustrating situation as well as elements shown […]

Responses of farmed silver foxes (Vulpes vulpes) to excessive food availability: Implications for using food as a yardstick resource in motivation tests

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 except while eating. Our first experiment therefore examined […]

Spatial memory for food hidden by rats (Rattus norvegicus) on the radial maze: Studies of memory for where, what, and when

Rats (Rattus norvegicus) were allowed to hide food items on an 8-arm radial maze by carrying the items from the center to boxes at the end of each arm. Retrieval tests given after rats had hidden 4 items showed that they selectively returned to the maze arms where food had been hidden (Experiments 1 and […]

Making inferences about the location of hidden food: Social dog, causal ape

Domestic dogs (Canis familiaris) and great apes from the genus Pan were tested on a series of object choice tasks. In each task, the location of hidden food was indicated for subjects by some kind of communicative, behavioral, or physical cue. On the basis of differences in the ecologies of these 2 genera, as well […]

Responses of White-Faced Capuchins (Cebus capucinus) to Naturalistic and Experimentally Presented Food-Associated Calls

In the context of foraging, many animal species produce specific calls that attract others. Researchers hypothesize that these vocalizations function to inform others about food; however, few studies have investigated whether food-associated calls alone are sufficient to cause individuals to respond as if they have been informed about food. Playback experiments on white-faced capuchins (Cebus […]

Citizens, Consumers and Animals: What Role do Experts Assign to Public Values in Establishing Animal Welfare Standards?

The public can influence animal welfare law and regulation. However what constitutes ‘the public’ is not a straightforward matter. A variety of different publics have an interest in animal use and this has implications for the governance of animal welfare. This article presents an ethnographic content analysis of how the concept of a public is […]

The effect of four different feeding regimes on rabbit behaviour

Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the effects of two commonly fed pet rabbit diets (extruded nuggets with […]
