Abstract     Field studies of infectious disease spread in animal populations appear to be laborious and costly. One can gather data from similar studies and develop a simulation model that fits specific conditions instead. The model then can be employed to study the spread of disease in a specific population. The Monte Carlo method was made use of to study the impact of porcine parvovirus infection on piglet production. The production processes with and without the porcine parvovirus infection were simulated for a period of six years. Regarding published research results an average loss of 1.5 liveborn piglet per litter of primiparous sows was assumed to be the only impact of parvovirus infection. The gilts that contract the infection within 70 days of gestation were chosen at random. Each alternative was replicated five time. There were in total 863 farrowings in the non-infected herd and 868 farrowings in the endemically infected herd. An average reduction of 0.37 liveborn piglet per litter and of 0.30 weaned piglet per litter in the endemically infected herd were found to be statistically significant. At the same time the number of feeding days per liveborn piglet increased by 0.41 per day. The other reproductive parameters did not significatly differ.
