Abstract
Researches were carried out on a number of 122 Grey Steppe breed females grouped into 8 groups: 3 groups in cattle unit increase: SCDCB Dancu Iasi (38 heads), USAMV Cluj (4 heads), Roua-Group Ialomita (3 heads), and 5 lots in Neamt population households (Tazlau - 6 heads, Tupilati-7 heads) and Tulcea (39 heads in Chilia Veche, Letea -18 heads and Pardina -7 heads), aiming the mean quantitative and qualitative of characters milk production. Data were exctracted of primary records of farms and direct measurements being statistically processed using SPSS 19 program, and statistical significance was done using ANOVA test. Quantitative milk production in cows Grey Steppe is now higher than in the production of this breed highlighted in studies over time, so the value of 1244 kg milk, registered in 1961, today it amounts to more than 2000 kg milk, which shows the high potential of this breed on milk production, modest to specialized breeds in milk production and even mixed. The average percentage of fat present values between 4.48 and 4.63% in specialized units and values less than 4.15 to 4.33% in the household population with significant statistical differences between values.

Key words: Gray Steppe, quantitative milk production, the average fat
