Does the presence of a human affect the preference of enrichment items in young, isolated pigs?

Pigs may be housed individually in both production and research settings. Gregarious by nature, pigs kept in isolation may show behavioural and physiological signs of stress. In this study we investigated the preference of individually housed pigs, for social and...

Ice cube treats for swine

The frozen Veggie Bite ice cube treat is hung inside the swine chain-link type enclosure with a Carabineer hook. ... Because swine avoid objects that are contaminated with feces, suspending this enrichment treat encourages more interaction, while incorporating food, making...

Enrichment of Göttingen Minipigs: Models of human hepatocellular carcinoma

Social or pair-housing is our main form of swine enrichment. The minipigs are group-housed in stalls that have sliding divider doors/panel which allow separation of animals for feeding and study procedures, as needed. Ideally, enrichment is designed to draw out...

The effects of music on animal physiology, behavior and welfare

Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that music may affect animals similarly...

Group space allowance has little effect on sow health, productivity, or welfare in a free-access stall system

Free-access stalls allow sows to choose the protection of a stall or use of a shared group space. This study investigated the effect of group space width, 0.91 (SS), 2.13 (IS), and 3.05 (LS) m, on the health, production, behavior,...

Does stocking density modify affective state in pigs as assessed by cognitive bias, behavioural and physiological parameters?

Recent studies suggest that emotional state can affect cognitive abilities of humans and non-human animals, determining biases in information processing. Negative mental states, such as anxiety or depression, induce pessimistic judgments of ambiguous stimuli. These assumptions may be used to...

Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs

Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore...
