Environmental Enrichment

Influence of visual cover on ramp climbing behavior in guinea pigs

To ensure the optimal welfare of a species in captivity, housing and enclosure design must align with the ecology, physiology, and behavioral biology of the animal. For the guinea pig (Cavia porcellus), a popular pet and laboratory animal, it is...

The inoculation fallacy: why early enrichment cannot compensate for poor adult environments

Early-life environmental enrichment (EE) is widely promoted as a route to building resilience and competence, yet these benefits rarely persist when adult environments lack opportunities for agency. Resilience and competence are behavioral properties of current reinforcement contingencies, not internal traits....

Feather pecking in non-beak-trimmed and beak-trimmed laying hens on commercial farms with aviaries

Severe feather pecking (SFP) is a major animal welfare problem in layers. It results in pain and injuries in the affected animal. SFP is a behavioral disorder and should not be confused with aggressive pecking. The aim of our study...

Cause and prevention of injurious pecking in chickens

This collection features three peer-reviewed literature reviews on feather-pecking in poultry. The first chapter describes the three main forms of injurious pecking (IP) in poultry: tissue pecking (TP), aggressive pecking (AP) and feather-pecking (FP). It discusses the origin of severe...

A high enrichment replenishment rate reduces damaging behaviors and increases growth rate in undocked pigs kept in fully slatted pens

One of the difficulties in complying with the prohibition of routine tail docking is a lack of effective alternative solutions to prevent tail biting, especially in fully slatted systems. This study compared three slat-compatible enrichment replenishment strategies for pigs. Forty-eight...

Efficacy of an interactive apparatus as environmental enrichment for common bottlenose dolphins (Tursiops truncatus)

Environmental enrichment is a key component in improving the psychological and physiological well-being of animals under professional care. Environmental enrichment involves the addition of stimuli, including objects and cognitive challenges, into the environment in order to increase species-specific behaviour and...

Welfare benefits after the implementation of slow-feeder hay bags for stabled horses

Horse confinement is a common practice worldwide. However, preventing horses from grazing and denying them social interaction can compromise their welfare and lead to undesirable consequences. Considering the hypothesis that increasing the forage consumption time can lead to improved welfare,...

Investigating optimal levels of platform perch provision for windowed broiler housing

Broiler chickens show a preference for platform perches over traditional bar perches. Further information is needed on the optimal provision of these perches in order for them to be successfully installed in commercial systems. This study was designed to compare...

The scent of enrichment: Exploring the effect of odour and biological salience on behaviour during enrichment of kennelled dogs

Worldwide, millions of dogs are held in kennels for extended periods of time and may experience compromised welfare. Enrichment, often using toys, is considered important to minimize the negative impacts of kennelling. However, the value of this enrichment may be...

Use of a mechanical brush by dairy cows with chorioptic mange

Mechanical brushes allow cows to groom. Mange is common in indoor-housed cattle, and this affliction may affect cow motivation to use a mechanical brush. The aim of this study was to assess changes in dairy cow motivation to use a...
