Milk quality is influenced by many factors including rank lactation. This study aims to present the evolution of the main quality parameters of milk as the fat, protein, lactose, dry matter and the number of somatic cells for the first five lactations in Bălţată Românească breed during twelve official controls, starting in June 2015 until the month of April 2016. The biological material studied was represented by herds of dairy cows in three farms from Sălaj County (Crasna, Marin and Bodia villages). Analyzing qualitative parameters of milk obtained from the herd in lactation 1 during the 12 controls, there was a percent of 3.50% fat, 3.05% protein, 4.49% lactose and 8.48% dry substance in farm from Crasna. These parameters varied over the five lactations, the highest values being ranked in lactation five. Herd from Marin farm presented a fat content of 4.44% in lactation 2, while the lowest percentage of fat was recorded in lactation 3 (3.66%). Regarding the protein, the highest percentage was obtained in lactation 2 (3.70%) and the lowest in lactation 1 (3.39%). Lactation rank affects milk quality, so in lactation 1 there were recorded the lowest values of quality parameters of milk.
