The research was performed during 2002-2007, on 86 Romanian Spotted primiparous cows, structured function of the dairy production level and number of milking. The time interval when their maximum lactation was noticed, in three consecutive days, was considered for recording the main qualitative and quantitative traits. On 19 of those primiparous cows, structured by two production levels and milking intervals, the main morpho-functional traits of the udder and its suitability for the mechanic milking were studied. On five primiparous, during the same lactation interval, the same quantitative traits were studied in dynamics by 5 samples each, during two milking time interval, on 22 samples in morning milking, respectively. The results were calculated and statistically interpreted, and they are synthetically presented in 5 tables and 3 graphics. The main aspects resulted from our research emphasized some qualitative and quantitative traits, their evolution and effect of the production level and number of milking. We also priority emphasized the main milk components in evolution by milking and possibility of fractionate valuating of the trade milk by valuation destinations.
