Abstract: The present study was conducted in the ten commercial dairy farms maintaining minimum of 100 animals as a herd and adopted the automization in milking in and around Hyderabad city of Telangana State. The milk samples was collected from automated urban dairy units at three different strata, that is at composite cow milk (S-1), bulk milk tank (S-2) and after processing (S-3).Dairy units were categorized into fully and semi- automated dairy units. The average fat% values in fully automated farms was more than the semi-automated farms. SNF values are almost similar in both automated and semi-automated milk samples. It is positive sign and profitable as the price for milk is given based on the fat percent. Quality of milk samples was tested and found that pH values ranged within normal i.e between 6.6-6.8. It means that milk produced in the fully automated farms have better keeping quality. Regarding microbial quality in general RRT grades of first and second strata milk samples was fair but in fully automated farms three strata samples for RRT graded as good which shows good keeping quality. The somatic cell counts are high in all the three strata samples in all the dairy units which is of concern. In terms of SPC count fully automated units samples are of goodgrade but in semi-automated first two strata samples are good and third strata sample was graded as fair. All the milk samples shown coliforms in 1:100 and 1:10 dilution and graded as not satisfactory.
