Welfare Assessment

Review: Gut microbiota—a powerful tool for improving pig welfare by influencing behavior through the gut–brain axis

Animal welfare is one of the core concerns in the field of animal science, with behavior serving as a direct reflection of emotional state and health, and thus a key indicator for welfare assessment. With the widespread adoption of intensive...

Assessing the relationship between incisor wear, age, and body condition in Dohne Merino ewes (Ovis aries)

Sheep (Ovis aries) are stoic, prey animals that have evolved to mask signs of pain and vulnerability, making behavioural indicators of poor welfare difficult to detect. Body condition scoring (BCS) remains one of the most practical, animal-based indicators of chronic...

Using the Welfare Quality® framework to develop a welfare assessment protocol for captive chimpanzees (Pan troglodytes)

Good welfare is of inherent value to all captive animals and promotes species conservation objectives. Concern for animal welfare is growing globally, and research shows that animal welfare is a top priority for zoo visitors. There is, therefore, an urgent...

A scoping review on salivary oxytocin and vasopressin measurement in the dog

Oxytocin (OT) and vasopressin (AVP) are attracting interest as potential measures for dog welfare and human-dog interactions. The potential for detection and measurement of these two neuropeptides in canine saliva provides a viable alternative to more invasive collection methods. This...

Findings and refinements from a decade of applying the Cetacean Welfare Assessment (“C-Well”) to multiple species on public display

Zoo animal welfare assessments can be applied to multi-species risk evaluations to species-specific, animal-based protocols. The latter are more difficult to develop and implement due to time-intensive data collection and difficulties with standardisation. The Cetacean Welfare Assessment (C-Well) was published...

Tracking epidermal cortisol and oxytocin in managed bottlenose dolphins as potential non-invasive physiological welfare indicators

Growing concern over cetacean welfare has highlighted the need for rigorous, science-based assessment methods. Within this context, epidermal cortisol (ECC) and oxytocin (EOC) concentrations have emerged as potentially valuable physiological indicators. In this study, we first validated the analytical measurement...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Application of the horse grimace scale in horses with dental disease: Preliminary findings
