Assessing animal welfare: A triangulation of preference, judgement bias and other candidate welfare indicators

To assess the welfare of captive animals, validated measures, so-called ‘welfare indicators', are required. We used a triangulation approach to investigate the extent to which different measures converged to provide corroborating evidence of welfare. Laying hens were exposed to living...

Physical enrichment research for captive fish: Time to focus on the DETAILS

Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted the many nuances involved. Effects are known...

Understanding behaviour to improve the welfare of an ornamental fish

Some common practices in aquaculture, ornamental trade and fish facilities may disturb the behavioural repertoire of fish and its natural adaptive value, reducing welfare and impairing fish production. Hence, it is necessary to understand fish behaviour, as well as the...

An apparatus for automatically training and collecting individualized behavioral data with socially housed rodents

Background: Conventional methods for individually housing, training, and testing rodents in behavioral assays can impose constraints that may limit some kinds of experimental external validity, preempt environmental enrichment, impose heavy experimenter time burdens that limit high-throughput data collection, and negatively...

Preference for and maintenance of interest in suspended enrichment toys in confined growing pigs

The objective of the present study was to evaluate the preference for, interest in, and behavior of growing pigs provided with three different suspended enrichment toys in a four-compartment environmental preference chamber (EPC). Sixty pigs at 70±2 days of age...

Interest in coloured objects and behavioural budgets of individual captive freshwater turtles

Recent studies showed that freshwater turtles display inter-individual differences in various behavioural traits, which may influence their health and welfare in captivity due to differences in response to husbandry and enrichment strategies and in ability to cope with the limitations...

Goal-oriented behavioural and environmental enrichment in aquarium species

Environmental enrichment is a common tool used in zoo and aquarium settings to provide mental and physical stimulation to animals under human care. This paper aims to present a primary approach to goal-oriented environmental and behavioural enrichment following a simplified...

Evaluation of environmental enrichment for Xenopus laevis using a preference test

Xenopus laevis frogs have long been widely used as an animal model in research. However, their husbandry has scarcely evolved, although they are prone to environmental stress. Environmental enrichment has been shown to improve animal welfare and adaptation, as well...

Minimizing complications in a porcine survival craniotomy model

A large craniotomy survival porcine model is useful for scientific research. The surgical approaches and complications of craniotomies in pigs have not been published before. This study describes how large craniotomies were performed in 46 pigs and how the risk...

Use of running plates by floor housed rats: A pilot study

The outfit of husbandry facilities of, and the enrichment provided for, experimental rodents plays an important role in the animals' welfare, and hence also for the societal acceptance of animal experiments. Whether rats and mice benefit from being provided with...
