The paper aimed to present the economic weights of milk yield, fat and protein percent estimated in the population of Romanian Buffalo from Șercaia Research and Development Station. A total 609 milk yield and associated characters records, belonging to 87 females, which coming from 11 sire families, for 7 lactations were analysed. The method used was multiple linear regression, and as a global indicator the „mozzarella index” was used. The economic values for milk yield, fat and protein percent in seven lactations were calculated as: € 0.9636, € 0.1367, € -0.0974; € 0.9729, € 0.0912, € -0.0661; € 0.9948, € 0.1978, € -0.1935; € 0.9922, € 0.1506, € -0.1452; € 0.9932, € 0.2691, € -0.2645; € 0.9891, € 0.1454, € -0.1352; € 0.9890, € 0.1708, € -0.1597. Results indicated that a major weight should be given to milk yield and fat percent. Negative value associated with protein percent suggest that the fat had a higher price compared to protein, and the payment system should be based on milk yield and fat percent for mozzarella production.
