Abstract


The aim of this study was to assess the milk production dynamics in one dairy farm rearing both Brown andRomanian Spotted breed cows. The study was carried out at the Research and Development Station for BovineRaising Arad, on 321 lactations obtained from Romanian Spotted cows and 117 lactations from Brown cows. Theselactations were classified according to the age of cows in first, second, third, fourth and fifth lactation. The milk yieldin the first lactation was the lowest both in Romanian Spotted and Brown cows (5745.86 kg and 7117.00 kg,respectively), while the maximum milk yield per lactation was produced in the fourth lactation by the RomanianSpotted cows (6692.81 kg) and in the fifth lactation by Brown cows (7898.19 kg). Romanian Spotted cows produced85.85% milk in the first lactation from the maximum lactation, while the Brown cows produced 90.11% in the firstlactation from the highest lactation. There was concluded that there are differences regarding the precocity for milkproduction and the dynamics from one lactation to another between the two breeds.
