Blood sampling in Göttingen minipigs—a case study of two standard methods and clicker training as a restraint-free alternative (2025)

Blood sampling often requires restraint that negatively affects animal welfare. This case study evaluated three methods for jugular vein blood sampling (V-bench, sling, and clicker training) with the overall aim of assessing the negative impact on animal welfare and providing...

Hematological reference intervals for Danish crossbred Landrace Yorkshire Duroc (LYD) pigs used in biomedical research (2025)

The health and welfare of pigs used in biomedical research is essential to research quality and compliance with the 3Rs (replacement, reduction, and refinement). Hematological variables are objective markers to quantitatively determine health issues and evaluate physiological differences before and...

Welfare implications of low-dose atipamezole reversal of tiletamine/zolazepam/xylazine anaesthesia in pigs (2025)

Anaesthesia is sometimes required for the effective restraint of laboratory pigs for sample collection. Yet, anaesthesia can initiate a range of physiological disruptions that can increase variability in study data and lead to poorer animal welfare. Judicious use of anaesthesia...

A positive-reinforcement training regimen for refined sample collection in laboratory pigs (2025)

Positive-reinforcement training of laboratory pigs can reduce the reliance on forced manual restraint and anaesthesia for sample collection, reducing stress and physiological disruption. Training regimens for laboratory pigs typically rely on specialised equipment for restraint, such as Panepinto slings, with...

By your side: How social support affects training duration, task performance and behaviour of pigs in a judgement bias task (2025)

Pigs (Sus scrofa domesticus) and most other farmed species are social animals for whom social isolation is known to cause stress. However, their social nature is commonly ignored in behavioural and cognitive tasks, on which they are trained and tested...

A new therapy to alleviate the inflammatory injury of piglet intestine caused by short-distance transportation—music (2025)

The purpose of this study was to explore whether music can reduce stress in animals by regulating the activity of the hypothalamus pituitary adrenal cortex (HPA) axis and reducing the concentration of cortisol. The control group was not played with...

Gilts are motivated to exit a stall (2025)

Stalls (or crates) are still a common type of housing in the swine industry, despite public concern and regional legislation restricting their use. In this study, we examined the motivation of gilts to exit a stall. Sixteen stall-naïve gilts (Large...

Long term ear and saphenous cannulation to perform blood sampling over longer periods using the Seldinger technique (2024)

The standard practice to collect a blood sample from a Minipig is to invert the animal onto its back and into a cradle. The blood sample is then collected via jugular venepuncture. This technique can cause large amounts of stress...

Exploring the effect of play on heart rate variability as a measure of positive emotional states in pigs

Play behaviour has been suggested to be inherently rewarding for animals, inducing positive emotional states. The psychophysiological effect of emotions can be assessed through heart rate variability (HRV), serving as a proxy measure of sympathovagal balance. This study investigated how...

On your terms or mine: Pigs’ response to imposed gentle tactile contact vs

Positive human-animal interactions (HAIs) can be intrinsically rewarding and facilitate positive human-animal relationships. However, HAI paradigms vary across studies, and the influence of different interaction paradigms on the animal's response has been overlooked. We compared the behavioural responses of pigs...
