- Abstract
The current study was carried out to evaluate the quality of raw milk, in rainy and dry seasons in 2012, 2013 and 2014, in Goiás State, Brazil, by means of the hygienic-sanitary indicators TBC and SCC, comparing with the legal limits of the Normative. A total of 1,600 dairy herds of Goias State, that constitute the database of the Milk Quality Laboratory, were evaluated. Monthly data regarding TBC and SCC were analyzed. Explanatory variables were associated to time (years 2012 to 2014) and period (rainy and dry season). For statistical analysis, Scott Knott test at 5% significance was employed. There was statistical difference (p>0.05) when rainy and dry periods were compared along the years 2012 and 2013 for TBC and SCC. Geometric mean of TBC and SCC in 2012, 2013 and 2014 were within the legal range of 300,000 CFU/mL and 500,000 Cells/mL, but 23% and 21% of the herds, respectively, were above the legal range. The findings of this study reveal milk quality is highly affected by seasonal variations, i.e., rainy and dry seasons, indicating the need of a more effective control during the rainy period.
