Description	The aim of this study was to determine the effect of a calving season on the Wood’s model parameters of the lactation curve and its characteristics. The observed cows (with minimum 75% of Czech Fleckvieh breed) formed three parity groups: parity 1 - 350 853 cows, parity 2 - 269 276 cows and parity 3 - 175 029 cows. The Wood’s function parameters were calculated and the lactation characteristics estimated: partial milk yields per 1-100 days, 100-200 days and a total milk yield 305-d, the peak yield – amount and day, IP 2:1 and a coefficient of the declination rate of the lactation curve. The calving season significantly affected the parameters of the lactation curve, the persistency of lactation and the number of days-in-milk at peak yield; it had no significant effect on the other characteristics. In general, the cows which calved in winter and autumn had more persistent lactations. The first-parity cows reached the peak yield sooner if they calved in summer, the older cows in summer and autumn.
