The objective of this study was to determine the influence of the lactation rank on the milk production level and total days in milk in the Fleckvieh-type population raised at the Research and Development Station for Bovine Raising - Arad. Researches were carried out on 350 lactations, as follows: 52 first lactations, 66 second lactations, 81 third lactations, 79 fourth lactations, 43 fifth lactations, and 29 sixth lactations. The average lactation was 344.65 days, with the longest lactation the fourth parity (359.31 days), while the shortest was found in the first (331.82 days). The milk production was on average 6035.66 kg with a maximum yield of 6692.81 kg reached in the fourth lactation, and the lowest in the first lactation (5745.86 kg). The first lactation represented 86% of the maximum lactation. There were significant differences for milk production between the first two lactations and lactations 4, 5, and 6, as well as between the fourth lactation and lactations 5 and 6.
