Resumo: | ABSTRACT The influence of seasonality and the training and implementation of good dairy farming practices on raw milk production and quality was evaluated on dairy farms in Minas Gerais State, Brazil. The physico-chemical composition, somatic cell count (SCC) and total bacterial count (TBC) were determined in 3,096 milk samples collected from bulk tanks originated from 43 dairy farms over a three-year period and correlated with key climatic factors. The recommended milking management practices were applied through a training program and correlated with the seasonal data in three stages: I) prior to training (dry period); II) 48 days after the training (transition period); III) 96 days after the training (rainy period). In the first stage, a diagnosis of the situation was performed with raw milk samplings for laboratory analysis, and training for implementation of good milking practices. In stages II and II, the checklist and laboratory analysis were also performed. The rainfall and high temperatures were found to represent the main factors affecting the milk composition and production, and TBC. The composition and physical properties of raw milk, and the TBC and SCC parameters can be controlled or minimized by applying proper milking management practices and constant monitoring.
