Abstract

The objective of this study was to analyze the influence of seasonal changes on milk quality in Western Santa Catarina, Brazil. Dairy farms (799) had raw milk samples (9144) collected and analyzed for fat, protein, SCC (somatic cell count) and TBC (total bacterial count). Samples were collected from cooling tanks on the farm during the months of October 2009 to September 2010 and grouped into four seasons (summer, autumn, winter, and spring). The data were classified according to the normative instructions 51 and 62 the Ministerial of Agriculture, and also according to a quality pay system adopted by the dairy industry in the region of the study.
