Welfare Assessment

Place conditioning as evaluation of affective valence in piglets

The emotional valence of animals is challenging to assess, despite being a key component of welfare. In this study, we attempted to assess emotional valence through memory in 1- and 3-week-old piglets. It was hypothesized that piglets would spend less...

The influence of age, sex, and season on hematological parameters in a captive population of former laboratory chimpanzees (Pan troglodytes)

This study aimed to establish a baseline hematological profile and examine the influence of age, sex, and season on hematological parameters in captive chimpanzees (Pan troglodytes) living in a humid tropical climate. Hematological parameters are a useful tool for assessing...

An exploration of the postural, location- and social contact- related sub-characteristics of inactive but awake behaviour as a depression-like indicator in mice

Inactive behaviour is essential to life. However, specific forms of inactivity may be indicative of compromised welfare in certain captive conditions. Inactive but awake behaviour (IBA - spontaneous, motionless awake behaviour without interacting with the surroundings) has been documented in...

Reducing hay waste from New Zealand white rabbits (Oryctolagus cuniculus) by switching to hanging wire feeders from conventional food bowls

Rabbits require daily dietary fiber (hay) to help maintain a healthy digestive tract. As per our standard operating procedure (SOP), we give the rabbits hay and other daily food enrichment in a bowl. Rabbits are intelligent, playful, and curious animals...

Deep learning for face detection and pain assessment in Japanese macaques (Macaca fuscata)

Facial expressions have increasingly been used to assess emotional states in mammals. The recognition of pain in research animals is essential for their well-being and leads to more reliable research outcomes. Automating this process could contribute to early pain diagnosis...

Welfare assessment in pigs using the salivary proteome

Identifying the potential presence of stress at the pig farm is fundamental since it affects pig welfare. As a result, a reliable and straightforward tool to monitor stress could record the welfare status of the animals. Although numerous methods to...

Will the white blood cells tell? A potential novel tool to assess broiler chicken welfare

This study assessed qualitative and quantitative leukocyte evaluation as potential broiler chicken welfare indicators, contributing to the limited literature on white blood cell (WBC) morphology as a diagnostic tool for welfare. Broiler chicken welfare within four poultry houses (PH) 1...

A systematic approach to defining and verifying descriptors used in the Qualitative Behavioural Assessment of sows

Qualitative Behaviour Assessment (QBA) is a welfare evaluation tool that uses a holistic approach to capturing an animal's emotional state. Lists of QBA descriptors validated to assess pig welfare exist, but their definitions are often not described in peer-reviewed literature...
