Exploration of skin redness and immunoglobulin A as markers of the affective states of hens

Non-invasive markers of affective states can help understanding animals' perception of situations and improving their welfare. These markers are scarce in avian species. In this study, we investigate the potential relation between alterations in facial skin redness in hens and...

Changes in enclosure use and basking behaviour associated with pair housing in Tokay geckos (Gekko gecko)

Due to often insufficient information, reptiles suffer welfare issues and increased mortality in captivity. In particular, the impact of the social environment remains poorly understood, despite evidence suggesting its' importance for welfare in a wide range of social animals. The...

Husbandry protocols for juvenile loggerhead sea turtles (Caretta caretta) based on stress response to stocking density and dry-dock time

When necessary, sea turtles are held captive for veterinarian care and research purposes. Protocols and basic guidelines have been described for husbandry of sea turtles with veterinarian needs but not considering physiological indicators of animal welfare. Because all sea turtle...

Social stability via management of natal males in captive rhesus macaques (Macaca mulatta)

Keystone individuals are expected to disproportionately contribute to group stability. For instance, rhesus macaques (Macaca mulatta) who police conflict contribute towards stability. Not all individuals' motivations align with mechanisms of group stability. In wild systems, males typically disperse at maturity...

Influence of deep-litter bedding materials on environmental and welfare-related factors in boar studs

In recent years, it has become increasingly difficult for artificial insemination (AI) centers to procure high-quality bedding materials. The aim of this study was to investigate influences of bedding materials on selected environmental and welfare-related aspects in breeding boars. Including...

Housed dairy cows utilise varied environmental enrichments and show diverse inter-individual variation in habituation

There is currently a focus on the importance of providing positive experiences to farm animals, which can be facilitated through the provision of environmental enrichment. Brushes are an established enrichment resource for dairy cows, however, enrichment opportunities beyond this appear...

Paper towel shredding as a novel, affordable, noninvasive method for detecting arousals in hibernating rodents

Many research groups explore the regulation of hibernation or compare the physiology of heterothermic mammals between the torpid and aroused, euthermic states. Current methods for monitoring torpor (for example, infrared cameras, body temperature or heart-rate telemetry, and motion sensing) are...

Anesthesia and humane euthanasia methods for king worm larvae (Zophobas morio)

A growing spotlight on insect welfare as research subjects, fodder for vertebrate animals, and patients for veterinarians highlights the need to establish humane euthanasia methods for these species. An insect of increasing commercial importance is the king worm (Zophobas morio),...

The protective effect of social support: Can humans reassure pigs during stressful challenges through social learning?

Farm animals can socially learn to trust a human after observing that human handling a familiar conspecific gently, even if they never positively interacted with the human themselves. This study aimed to evaluate whether pigs are reassured by a human...
