Introduction - The aim of this study was to compare milk quality from different milking systems, manual and mechanical. Material and Methods - For this study the animals and equipaments of a milk farm located at Cunha City, São Paulo were used fifteen cows were milked manually and other 15 milked using vacuum equipment, totalizing 30 animals. Each sample was tested for three different analyze: milk composition, somatic cells count (SCC) and total bacterial count (TBC). Results - Milk composition was similar for treatments. However, the values of SCC were higher on animals milked manually (446, 366 and 342 x10 cels/mL vs 49, 93, 125 x 10 cels/mL while the TBC level were high on animals milked with the equipment (11.8, 119.4, 92.2 vs 4.6, 11.8, 29.6 x 10 CFU/mL). Conclusion-This results indicates high bacterial contamination on mechanical equipments and no existence of corelation between SCC and TBC.
