Shelter use by horses during summer in relation to weather conditions and horsefly (Tabanidae) prevalence

National legislation requires shelter access for horses kept outside during winter, whereas there are no requirements for shelter access to provide shade and a refuge from biting insects during summer. This study investigated use of artificial shelters by 10 horse...

Comparing gradual debonding strategies after prolonged cow-calf contact: Stress responses, performance, and health of dairy cow and calf

We assessed effects of two-step debonding strategies in calf rearing systems with different types of prolonged cow-calf contact (CCC) on stress responses, health and performance of dairy cows and calves. Forty-eight Holstein Friesian cow-calf pairs had either: 1) full contact...

Perch use in commercial broiler breeders – Preference for perch material and effect of age

Unlike for laying hens in most European countries, few broiler breeders have access to perches, and there is a need for more knowledge on perching behavior in broiler breeders. The aim of this study was to investigate the overall use...

An international perspective on ethics approval in animal behaviour and welfare research

Ethics assessment is essential in studies that involve animals as subjects, which includes research on animal behaviour and welfare. Although ethics review mechanisms within institutions are long established in many regions, processes may be non-uniform across different cultures, institutions, and...

Enrichment with classical music enhances affiliative behaviours in bottlenose dolphin

Environmental enrichment is a crucial element for the promotion of welfare of animals kept under human care. While a large variety of environmental enrichments has been proposed and studied for terrestrial animals, including a growing area represented by acoustical enrichment...

A deep transfer learning model for head pose estimation in rhesus macaques during cognitive tasks: Towards a nonrestraint noninvasive 3Rs approach

Head orientation is a measure of attention used in behavioral psychological research with non-human primates. It is used across a broad range of disciplines and settings, from the field to the laboratory. Field methods are time consuming with risk of...

Evaluation of different types of enrichment – their usage and effect on home cage behavior in female mice

Numerous studies ascertained positive effects of enriched environments on the well-being of laboratory animals including behavioral, physiological and neurochemical parameters. Conversely, such conclusions imply impaired animal welfare and health in barren husbandry conditions. Moreover, inappropriate housing of laboratory animals may...

Improving well-being and survival in the 6-OHDA lesion model of Parkinson´s disease in mice: Literature review and step-by-step protocol

Parkinson's disease (PD) is the most common neurodegenerative motor disorder and primarily affects movement control but also a range of non-motor functions. With unknown etiology and lack of cure, much research is dedicated to unravel pathological mechanisms and improve clinical...

Non-invasive sampling of water-borne hormones demonstrates individual consistency of the cortisol response to stress in laboratory zebrafish (Danio rerio)

Glucocorticoid (GC) stress hormones are well-known for their impact on phenotypic traits ranging from immune function to behaviour and cognition. For that reason, consistent aspects of an individual's physiological stress response (i.e. GC responsiveness) can predict major elements of life-history...
