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...

Tail and ear movements as possible indicators of emotions in pigs

A better understanding of animal emotions is an important goal in disciplines ranging from neuroscience to animal welfare science, but few reliable tools exist for measuring these emotions. Play behaviour is generally recognized as a trigger of positive emotions in...

Evaluating environmental enrichment as a method to alleviate pain after castration and tail docking in pigs

Castration and tail docking are common management practices performed on commercial swine farms in the US and around the world to reduce adverse behaviors and the occurrence of boar taint. However, these practices themselves are a welfare concern for the...

Pre-weaning environmental enrichment increases piglets’ object play behaviour on a large scale commercial pig farm

Environmental enrichment is a legal requirement for European pig farms. The suitability of enrichment materials for neonatal pigs is understudied and has not been tested in commercial settings. This study investigates the effect of hanging objects and substrate as two...

Selection of putative indicators of positive emotions triggered by object and social play in mini-pigs

Positive welfare is more than the absence of negative experiences. Nevertheless, there are few feasible animal-based measures for positive welfare. This study aimed to investigate whether object and social play behaviours in pigs, which is believed to trigger positive emotions,...
