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...

Rat boredom-like behaviour in a monotonous versus a varied foraging task: Effects of sensory variation

Evidence increasingly reveals that non-human animals in monotonous situations can show boredom-like states, distinctively manifesting as increases in both arousal-seeking, restless behaviour and low arousal, drowsy behaviour. However, task related boredom has been little investigated in animals, but could have...

An assessment of paper pulp dishes for safe and enriching diet delivery

It is common practice for laboratory animals to be provided with diet in the form of wet mash or gel for various situations such as post-weaning and postoperative recovery. This study tested the use of paper pulp dishes as a...

Evaluating behavioral management practices for laboratory nonhuman primates: An international survey

The largest survey to date of behavioral management practices among facilities breeding and housing nonhuman primates (NHPs) for research was conducted from 2019 to 2020. Its primary objective was to analyze and compare practices across the European Union (EU), the...

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...
