The stillbirth rate, especially in Holstein-Friesian heifers increased gradually during the last 20 years, therefore, in order to be able to confirm similar tendency, 8427 calvings in a Hungarian Holstein-Friesian dairy farm during a five-year period were evaluated. Data were evaluated according to the incidence of stillbirth on an annual (Table 1), and parity (Figure 1) basis. The stillbirth rate was also evaluated according to parity (Figure 2), as well as its incidence rate regarding all calvings based on parity and year (Table 2), sires (Table 3). In accordance with the literature data, stillbirth can cause severe economic losses in Hungary, as well. The importance of the examinations in the perinatal period is discussed in order to be able to moderate the economical losses caused by perinatal mortality.
