Cattle

This directed network describes the dominance behavior observed between dairy cattle (Bos taurus) at the Iberia Livestock Experiment Station in Jenerette, Louisiana, USA. A node represents a cow and an edge represents the dominance of the left cow over the right cow. The edge weights indicate how often this besting behavior was observed.
