Economic consequences for footrot development | ||||
Benefit from shorter fattening time | 1′648 | 40′665 | 52′754 | −20′474 |

Intangible cost (animal welfare and others) | 553′422 | 192′775 | 99′936 | 691′667 |

The discount factor is 1. All cost and benefit are expressed in constant 2014 prices. Direct cost and treatment cost are summed over time of the management period (2014–2030). The 95% confidence interval is reported in parenthesis. The total net economic effect is presented in Table 5.
Cost differences between small, medium, and large farms are taken into account. Composition of the cost categories depends on the scenario. On-farm labor costs are calculated as 28 CHF/h times the farm personnel’s time estimated for foot bathing, hoof trimming, and presence at clinical inspections or collection of samples for diagnostic tests. Third-party costs include clinical inspections by hoof controllers and veterinaries and diagnostic tests. Material costs include water and zinc sulfate. The saved costs associated with the reduction of fattening time were calculated by assuming that the costs per animal are 2.70 CHF/day, and animals are not prematurely slaughtered. Intangible costs are calculated based on national prevalence rates, given the results of the expert elicitations.
