Relationship between growth rate and oral manipulation, social nosing, and aggression in finishing pigs

Pigs may affect each other's health, welfare and productivity through their behaviour. The effect of a pig on the growth rate of its pen mates is partly heritable and is referred to as its social genetic effect. Social genetic effects,...

Friends with benefits: Social support and its relevance for farm animal welfare

Despite growing interest in promoting positive welfare, rather than just alleviating poor welfare, potential measures of good welfare, and means to provide it, have remained elusive. In humans social support improves stress-coping abilities, health, and promotes positive psychological welfare. Therefore,...

Indicators of positive and negative emotions and emotional contagion in pigs

For the welfare of group-housed animals, such as pigs, the emotional state of an individual pig is relevant, but also the extent to which pen mates are affected by the distress or pleasure of other individuals, i.e. emotional contagion, a...

Effect of marginal environmental and social enrichment during rearing on pigs’ reactions to novelty, conspecifics and handling

The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain × German Landrace pigs were reared in...

Effects of cognitive enrichment on behavioural and physiological reactions of pigs

Cognitive enrichment, a special form of environmental enrichment, addresses the cognitive abilities of animals in captivity. Through cognitive interaction with the environment, the animals regain a certain control over their environment, and essential resources, such as food or water, act...

The effect of rubber mats on preference and lying behaviour of group housed sows

This study analyses the preferences, as well as the lying behaviour, of sows with various types of mat in a group housing system lying area. The sows in the trial could choose between six bays with three lying surfaces (concrete,...

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...

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...
