Abstract
   The paper proposes an analysis on the influence of reproduction indicators on quantitative and qualitative milk production, obtained in a cattle farm in the mountainous area of Romania. The farm is located in the Dornelor Basin, Suceava County, with a herd of 20 cattle heads for Bălțată Românească, of which only 13 heads are registered in the Genealogical Register, benefiting from payments for the coupled support. In this sense, the following reproduction indicators were statistically processed: the age of the first calving, the service period, the calving interval and the number of calving / calving. The quantitative and qualitative indicators on milk production were also analyzed: duration of lactation, total milk production, daily milk / head production, % fat and% protein. From the statistically processed data it appears that the age of the first calving influences the total milk production, this registering values between 4821 liters / head and 8468 liters / head with a daily production between 12 and 23liters milk /head.
