Research on the causes of change in production and milk composition in the primary sector of production, transport and storage are important aspects and serve as a tool for improving the quality of raw materials and dairy products, since the consumer market is more demanding and growing demand. The objective of this paper was to evaluate the quality of milk depending on the type of milking and conditions of transport and storage. Between December 2010 and May 2011, samples were collected fresh milk directly from dairy herds and stored in refrigerated raw milk cooling tanks, insulated tanks and industrial silos. The electronic analysis (SCC, TBC and centesimal composition) were performed at the Laboratory of Milk Quality. It was used for statistical analyzes the statistical package ASSISTAT. The hand milking resulted in raw milk and raw milk refrigerated for best quality, which demonstrated the need to implement measures aimed at improving the hygienic quality of milk milked mechanically. The milk stored in silos industrial TBC showed higher compared to the milk stored in isothermal tank, however, both showed high microbial counts, which suggests the use of storage conditions conducive to microbial proliferation, inappropriate hygiene procedures and equipment of temperature and time above the storage required by Brazilian law. Produce raw material quality, according to current standards, resulting in higher yield and quality of dairy products, a situation that benefits industry and consumers.
