Milk yield such as production of milk, of milk fat, 4% FCM and content of milk fat in standard lactation of 305 days were investigated. Production of milk in standard lactation enables comparison of lactations of different durations. Also, the effect of order to lactation and calving season on mentioned traits was investigated in detail using the method of Least Squares (Harvey, 1987). Order of lactation demonstrated highly significant effect on all milk traits contrary to calving season without any significant effect on any of the investigated traits. Mean values of general average for production of milk were 5.630.27 kg, content of milk fat 3.98%, production of milk fat 225.22 kg, and production of 4% FCM 5.630.38 kg.
