In a globalization context, producing food only focused on quantity makes no more sense. At the same time, the quality becomes the most important step on food processing chain, since it s essential to guarantee life quality. Then, we purposed this study to verify the effect of private technical assistance on milk quality. The study was carried out during the dry and rain periods of the year, on 40 dairy farms located at the counties of Bela Vista de Goiás, São Miguel do Passa Quatro, Piracanjuba and Cristianópolis, in Goiás State, Brazil. The farms were randomly selected from herds with high results of somatic cell count (SCC) and total bacterial count (TBC). The effect of technical assistance on milk quality was evaluated using the results of milk analyses before and after visits of technicians on the farms. Milk samples were taken from bulk milk tanks and analyzed to somatic cell count (SCC) and total bacterial count (TBC) in electronic devices. We observed a significant decrease on the SCC and TBC after farmers had received technical assistance on milking procedures and mastitis control. The rain period didn t affect the observed results. As the SCC decreased, we observed an increase on SNF values of milk. So, we confirmed that technical assistance leaves to better milk quality, in any time of the year
