Early play fighting in pigs, analyzed using social network analysis (SNA), reduced aggression-related skin lesions. A central position in play fighting networks benefited young pigs, impacting later social interactions.
Area of Science:
- Animal Behavior
- Ethology
- Social Network Analysis
Background:
- Early play fighting is a common behavior in many species, potentially reducing future aggressive encounters.
- Understanding the long-term benefits of play fighting is crucial for animal welfare and social development.
Purpose of the Study:
- To investigate the impact of early play fighting network position on subsequent aggression-related skin lesions in domestic pigs.
- To assess if social network analysis (SNA) provides a more comprehensive understanding than dyadic analysis of social interactions.
Main Methods:
- Social network analysis (SNA) was used to quantify play fighting network centrality in 263 piglets over six days.
- Skin lesions resulting from aggression were recorded after dyadic contests and at 24 hours and 3 weeks post-group mixing.
Main Results:
- Pigs with a higher number of play fighting partners (in-degree) experienced fewer lesions in immediate dyadic contests (p=0.01).
- A higher degree centrality in the play fighting network was associated with fewer lesions 3 weeks after group mixing (p=0.088).
- Other network centrality measures did not significantly affect lesion counts.
Conclusions:
- The benefits of early play fighting on aggression are context-specific, primarily observed in immediate and short-term social interactions.
- Social network analysis offers valuable insights into the influence of early social experiences on later life outcomes.
- Enhancing play fighting experience through socialization did not directly reduce subsequent lesions.
