Fig. 7

Frequency distribution of the ingoing average topological overlap of the nodes (\(C_{i}^{in}\)). The illustration is separated by farm type, i.e. multipliers (a), farrowing farms (b), finishing farms (c) and farrow-to-finishing farms (d). The categories are organized as follows: 0: \(C_{i}^{in} = 0\), 1: \(0 < C_{i}^{in} \le 0.2\), 2: \(0.2 < C_{i}^{in} \le 0.4\), 3: \(0.4 < C_{i}^{in} \le 0.6\), 4: \(0.6 < C_{i}^{in} \le 0.8\), 5: \(0.8 < C_{i}^{in} \le 1.\)
