Milk quality according to the daily range in farm production in the Mesoregion Central Mineira and Oeste of Minas Gerais regions, Brazil

The objective of this work was to characterize milk production from the Central Mineira and Oeste Mesoregions regions in Minas Gerais State, Brazil, according to quality parameters such as somatic cell count, total bacteria count, and composition for specific production ranges. Average results for milk fat, protein, total and nonfat solids were compliant with Brazilian legal requirements (IN-62/2011) in all the production ranges selected. Average somatic cell counts (SCC) complied with the legal requirements of 600,000 cells/mL, except for the range with a daily production above 1,000 liters. However, average maximum values of 400,000 cells/mL are recommended for good milk quality. Total bacterial count was the most critical quality factor, with the highest values found in breeds with milk production above 500 liters per day.
