Exercise reward induces appetitive 50-kHz calls in rats

Rats express affective states by visible behaviors (like approach or flight) and through different kinds of ultrasonic vocalizations (USV). 50-kHz calls are thought to reflect positive affective states since they occur during rewarding situations like social play or palatable food....

Sham dustbathing in cages by subordinate hens is increased by a partition providing isolation

Subordinate hens express less sham dustbathing in cages than higher ranked hens, their bouts often being disturbed by a higher ranked hen. However, seeing conspecifics seems to encourage this behaviour by hens. So to avoid being disturbed, a partition between...

Can access to an automated grooming brush and/or a mirror reduce stress of dairy cows kept in social isolation?

In dairy farming, social isolation of cattle is commonly practiced for husbandry procedures such as artificial insemination, claw trimming and at times, for provision of medical treatment. When isolated, cows express physiological and behavioural signs of stress, such as elevated...

Implication and impact of straw provision on behaviour, lesions and pen hygiene on commercial farms rearing undocked pigs

According to the European Union Council Directive 2008/120EC, measures to minimise the risk for tail biting shall be taken before practicing tail docking, e.g. provision of manipulable material. Still, >90% of the pigs within EU are tail docked. Thus, management...

Does grouping environmental enrichments together affect the way they are used by commercially housed broiler chickens?

Identifying the most attractive ways of presenting environmental enrichments in commercial broiler housing may encourage use and optimise their effectiveness. This study investigated the effect of grouping straw bales (SB), oat hulls (OH; as a dustbathing substrate) and pecking chain...

The effects of green odour on domestic dogs: A pilot study

Green odour (a mixture of cis-3-hexenol and trans-2-hexenal), similar to cut grass, has been demonstrated to appease subjects of various species (rats, cattle, humans etc.) subjected to different stressful stimuli. The aim of this study was to investigate whether green...

The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition

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 during rear improved the...

Dairy goats use outdoor runs of high quality more regardless of the quality of indoor housing

For dairy goats in loose housing, access to an outdoor run has potential welfare benefits as it provides additional space, enables spatial separation and may offer items representing behavioural enrichment for the goats (e.g. brush, climbing possibilities). However, these benefits...

Inoculation stress hypothesis of environmental enrichment

One hallmark of psychiatric conditions is the vast continuum of individual differences in susceptibility vs. resilience resulting from the interaction of genetic and environmental factors. The environmental enrichment paradigm is an animal model that is useful for studying a range...

Effects of music enrichment on individually housed male New Zealand white rabbits

The beneficial effect of music has been demonstrated in many species. Although commercially available music CDs intended for use with rabbits are available, these enrichments have not been critically evaluated to determine whether they reduce distress. In this study, we...
