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...

An effective environmental enrichment framework for the continual improvement of production animal welfare

Substrates and objects are provided to farm animals on the assumption that they improve animal welfare by enriching the environment, but these often fail to consider the extent to which an environmental enrichment (EE) improves animal welfare, if at all....

Benchmarking enrichment efforts in the US & Canada across species and enrichment categories

Enrichment is important for animal welfare and data quality. Provision of enrichment opportunities varies between species and enrichment category. However, data benchmarking these differences does not exist. Our objective was to characterize enrichment provision and associated factors across species in...

Wool-pulling behaviour appears in a production system with grazing restriction and can be assessed through wool inspection

Sheep flocks can be reared in different production systems that differ in the duration of indoor housing and grazing restriction. Indoor housing can lead to aggressive interactions, such as blocking, threats and butts, whereas grazing restriction may cause wool-pulling. Wool-pulling...
