SUMMARY: Dairy cattle farming is one of Brazil’s main economic activities, playing an important role in the rents of millions of families and in quality feed. The aim was to study the influence of the racial pattern and the use of pre-dipping on the microbiological and physico-chemical compositions of raw bovine milk. The study was developed in Santana do Ipanema, a municipality located in the Brazilian Semiarido. The treatments consisted of the assessment of the jet order, racial pattern (Girolando and Holandesa) and the adoption of the dipping pré, each group counted ten animals. The results obtained were subjected to the analysis of variance and 5 % regression of probability for the type I error. For the comparison between the racial group and the use of the pre dipping, the comparison using the 5 % probability Tukey test was carried out. The order of milk jets has promoted a linear decresceste effect (P0,05) on the count of total bacteria, protein, added water, cryoscopic index and milk density, while the Girolando breed has lower fat content and a higher pH (P < 0,05) of the milk in relation to animals of the Holandesa breed. The use of pre-dipping promoted a reduction (P < 0,005) of the total bacterial count by 0,80 CFU ml-1 of milk. The advancement of milking (milk jets) and the use of dipping fosters a reduction in the bacterial burden of the ceiling, justifying the need to discard the first three milk jets.
