This paper explores breed characteristics of the Romanian Spotted Cattle, as far as the parameters of milk production and economic ones from Pantelimon, Mogosoaia and Afumati farms. For the purpose of determining total duration of lactation, milk production on total and normal lactation, the proportion of protein on total and normal lactation, the proportion of fat on total and normal lactation have been calculated using the statistics indicators: average, the variation, standard deviation, standard error of the average and the coefficient of variability. The researches carried out showed that the highest total duration of lactation has been obtained by Romanian Spotted Cattle on the Afumati farm (334.68 ± 1.82 days) with approximately 2.5% higher than lowest total duration of lactation (326.46 ± 1.87 days) at the Mogosoaia farm. The best average production of milk has been obtained at the Pantelimon farm 8092.63 ± 35.53 kg, top with 6,45% than that of Afumati farm and 17.85% than milk production obtained in Mogosoaia farm. Regard to the results obtained on average quantity of milk on normal lactation, showed that again the Pantelimon farm have been reach out the best results. Regarding at the percentage of fat, it showed that the best results have been obtained in the Mogosoaia farm 3.9 ± 0.004% followed by Pantelimon farm 3.75 ± 0.003 % and Afumati farm with 3.7 ± 0.004 %. About the developments in the milk quantity, of the percentage of protein and a percentage and quantity of fat in relation to lactation, it is found that biological material from the farms named above has a good precocity in the direction of milk production.
