dc.description.abstractSummary Background: Porcine parvovirus 1 (PPV1) is widespread in swine herds and can cause reproductive failure. Infection of susceptible pregnant females prior to development of foetal immunocompetence can result in embryonic and foetal death, mummification, stillbirths with smaller litter size and delayed return to oestrus, consequently significant financial losses for the producer. PPV1 vac cines are successfully used worldwide to prevent reproductive failures. Objectives: The aim of the study was to briefly present the effect of PPV1 infec tion on the foetus in susceptible gilts and to economically analyse the parvo virus vaccination in Hungarian pig herds. Materials and Methods: Based on international literature data a partial budget calculation was used to assess the economic losses due to PPV1 and to evaluate the financial benefits of a vaccination program in a 1000-sow pig herd by using average Hungarian production and price data of 2016. Results and Discussion: In the calculation we assume that in 12.2% of the gilts (55 out of 450) the detrimental reproductive effects of PPV1 infection could be observed yearly, which are the followings: the average number of liveborn piglets per litter decreases by 3 (from 12 to 9) and additionally for 24 gilts out of 55, which are in the first 30 days of their gestation, there is a prolonged return to oestrus with an average of 36 days (days open!) firstly because of the embryo/ foetal loss caused by PPV1. If there was no prevention on the farm, taking into account the decrease in gross margin (income over feed cost) due to the smaller number of weaned piglets, the estimated losses caused by PPV1 would amount to €12.7k on herd level and to €28.3 per breeding gilt annually. The estimation predicts that a breeding herd vaccination program is a cost-effective method for controlling PPV1-induced reproductive failure, because the vaccination cost is less than € 28.3 per breeding gilt yearly.en_US
