Aggressive behaviour at regrouping is a poor predictor of chronic aggression in stable social groups

Commercial pigs globally are routinely mixed into new social groups. This results in regrouping aggression predominantly during the first 24h which compromises welfare and productivity. Chronic aggression persists thereafter and is also undesirable. Management strategies are needed that reduce the...

A novel method for the analysis of social structure allows in-depth analysis of sow rank in newly grouped sows

Chronic stress response in fearful animals can result in depression of growth and reproductive performance. It is therefore important to be aware of at risk animals in the herd. Thus far ‘hierarchy' calculations have involved the use of fights won...

Associations between the dominance status and sexual development, skin lesions or feeding behaviour of intact male pigs

In boars, social relationships could influence pubertal development and feeding behaviour. The objectives of the present study were to determine the relationships between behaviour (agonistic, mounting and feeding behaviours), plasma sex steroids (oestradiol, testosterone) and fat androstenone. A total of...

Housing conditions do not alter cognitive bias but affect serum cortisol, qualitative behaviour assessment and wounds on the carcass in pigs

Measures of animal emotions are essential to assess animal welfare. Recently, the cognitive bias technique has been proposed as a measure of animal affective state. This technique is based on the premise that subjects in negative affective states make more...

A synthetic olfactory agonist reduces aggression when sows are mixed into small groups

Synthetic olfactory agonists mimic odours secreted by mammary glands in several mammal species and their application can reduce anxiety levels in both juvenile and adult animals. This investigation determined the effect of a commercially available synthetic olfactory agonist administration on...

Influence of enrichment material and herbal compounds in the behaviour and performance of growing pigs

Pigs reared in barren conditions are exposed to many different stressors, compromising their welfare and producing physiological and behavioural changes. The aim of this study was to assess the effect of environmental enrichment (EE) consisting of natural hemp ropes, sawdust,...

Effects of environmental enrichment on decision-making behavior in pigs

The animal's emotional state, potentially modulated by environmental conditions, may affect cognitive processes such as interpretation, judgement and decision making behaviour. The Iowa Gambling Task (IGT) is a common method to examine decision making behavior in humans in terms of...

Emotional states and emotional contagion in pigs after exposure to a positive and negative treatment

After-effects of events that elicit an emotional state on both the animals that experienced these events and on their group members have only scarcely been studied. We investigated effects of a positive vs. negative treatment on the behaviour and emotional...

Playful pigs: Evidence of consistency and change in play depending on litter and developmental stage

Play behaviour in pre-weaned piglets has previously been shown to vary consistently between litters. This study aimed to determine if these pre-weaning litter differences in play behaviour were also consistent in the post-weaning period. Seven litters of commercially bred piglets...

Using automated image analysis in pig behavioural research: Assessment of the influence of enrichment substrate provision on lying behaviour

Visual monitoring of pig behaviours over long periods is very time consuming and has possibility for observer bias. Automated image processing techniques now give the potential to carry out behavioural research in a more effective way. To illustrate this, an...
