Voluntary additional welfare monitoring of farm animals used in research: Maximising benefits requires sustained support

The aim of this project was to co-create an animal welfare monitoring system that incorporated both positive and negative welfare measures that would contribute to best practice husbandry standards of farm animals in a real animal research setting. Researchers worked...

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...

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...

Lambs cope better with gradual weaning and definitive maternal separation when housed with known-adult companion ewes

Gradual weaning reduces lambs’ distress during definitive maternal separation by progressively decreasing milk intake and maternal contact. However, repeated temporary separation during gradual weaning, followed by definitive separation, remains stressful and negatively impacts lamb behavior, immune function, and overall physiological...

Smart farming and Artificial Intelligence (AI): How can we ensure that animal welfare is a priority?

The increasing use of technology in livestock farming has the potential for making farming easier and more efficient and for improving animal welfare. There are also, however, potential dangers, one of which is that animal welfare becomes subordinated to the...

Mixing groups of sheep changes vocalizations when an individual animal is isolated (2025)

In recent years, welfare, which includes pleasurable and unpleasant emotions, is of utmost importance in animals reared under intensive farming systems. Various indices have been reported to evaluate welfare. Among them, vocalizations form non-invasive indices of animals' inner state. The...

Recommendations for measuring and standardizing light for laboratory mammals to improve welfare and reproducibility in animal research

Light enables vision and exerts widespread effects on physiology and behavior, including regulating circadian rhythms, sleep, hormone synthesis, affective state, and cognitive processes. Appropriate lighting in animal facilities may support welfare and ensure that animals enter experiments in an appropriate...

Does tail docking prevent Cochliomyia hominivorax myiasis in sheep? A six-year retrospective cohort study

Tail docking is a husbandry practice widely incorporated in sheep farms around the world. It is an irreversible mutilation that impairs animal welfare, both immediately and in the longer term. The defence of tail docking as a practice is centred...
