Abstract
Steppe Grey is an ancient breed of cattle that can be found on the present territory of our country since ancient times. In our country Steppe Grey is a breed of cattle considered at risk of extinction (having fewer than 1000 head), in danger of reach the critical limit of less than 100 animals, according to risk categories used by FAO. This paper has proposed calculating the degree of mating and inbreeding between female Gray cattle from SCDCB Dancu, in number of 48 heads and between bulls used at Ia and these, only 26.61 % of the female have between them relationship of relatednes and kinship ranging between 0.33 % for relatednes and kinship coefficient of 0.0156 / 0.0078 and 0.08 % for a factor of relatednes and kinship of 0.6125 / 0.30625.

Key words: Steppe Grey, relatedness, kinship
