Abstract
Research was conducted on a nucleus of 38 Grey steppe breed individuals from SCDCB Dancu, Iasi. Main pursue issues were to measure the main indices of the female body development from birth to the third calving and the qualitative and quantity character values of milk production for the first three lactations. Data were extracted from primary records of the farm and were processed statistically. Body development recorded mean values, for the main morphological indicators are within the breed limits for the Moldavian variety. Grey steppe, on normal lactation, recorded the following means values: 1st lactation -1519.55 kg milk, 2nd lactation -1640.90 kg milk, 3rd lactation -1774.78 kg milk. Average milk quality parameters were for the 1st lactation: 4.48 % fat, 3.52% protein; 2nd lactation: 4.54 % fat, 3.60 % protein; 3rd lactation: 4.72 % fat, 3.67% protein.

Key words: Grey steppe, morph productive characteristics, lactation
