The objective of this study was to quantify the milk's total bacteria l count of twenty farms in the towns of Patos de Minas and Lagoa Grande, MG. It had been used 530 samples from farms, randomly chosen, with two TBC's collections per month. These were analyzed by flow cytometry. The result was expressed in number of bacterial counts multiplied by 10³ mL. The geometric avegare of all farm's review was 24,72 x 10³ CBT/mL. According to the daily production of the properties, it was observed that there is no correlation between the daily production and cow's average with the values of TBC during the year. TBC's average in the rainy season, from October to March, was higher than the rest of the year, but did not exceed the limit of 300,000 CFU/mL. This demonstrates that the milk produced in these properties is in accordance with Normative Instruction (NI) 62, showing that it is possible to have quality standards during all months of the year.

The objective of this study was to analyze the profile of CCS of dairy farms in the municipalities of Patos de Minas and Lagoa Grande and compare the values of CCS with Normative Instruction 62. Twenty farms, chosen randomly, were used with collections of CCS twice a month, totaling 533 samples located in the regions of Patos de Minas and Lagoa Grande, belonging to the state of Minas Gerais. The average results of CCS of seventeen farms (85%) was around 336 x 10³, that confirm the quality of the milk from the two regions studied, even in times of greatest challenges as in the rainy season in semi-intensive systems. Only three farms (15%) had values above the wanted (average of 970 x 10³). [ABSTRACT FROM AUTHOR]
