Abstract

Social network analysis (SNA) has provided novel traits that describe the role of individual pigs in aggression. The objectives were to estimate the genetic parameters for these SNA traits and quantify their genetic association with skin lesions. Pigs were video recorded for 24h post-mixing. The observed fight and bullying behaviour of each animal was used as input for the SNA. Skin lesions were counted on different body parts at 24h (SL24h) and 3wk (SL3wk) post-mixing. A Bayesian approach estimated the genetic parameters of SNA traits and their association with skin lesions. SNA traits were heritable (h2=0.18 to 0.26) and strongly genetically correlated (rg>0.88). Positive genetic correlations were observed between 3 of the 4 studied SNA centrality traits with anterior SL24h, although they showed negative genetic correlations with anterior SL3wk. This study provides a first step towards potential integration of SNA traits into a multi-trait selection index for improving pigs’ welfare.
