Buffalo milk production is an activity that has grown in recent years, mainly due to the physicochemical characteristics found in this type of milk, which is the second most produced in the world. The objective of this study was to implement a milking system and monitor the identity and quality standards of buffalo milk produced at the Experimental Agronomic Station of the Federal University of Rio Grande do Sul. Samples were collected fortnightly between June and November 2021, totaling ten collections. The means obtained at the end of the monitoring were 4.84 g/100 g for fat, 4.64 g/100 g for protein, 5.06 g/100 g for lactose, 15.26 g/100 g for total solids, 10.42 g/100g for non-fat solids, 0.18 g lactic acid/100 mL of milk for acidity, 1.037 g/cm³ for density, -0.533°C for cryoscopic index, 3.5 x 105 cells/mL for somatic cell count, and 8.0 x103 CFU/ml for standard plate count. Residues of antibiotics and antiparasitics were not found. An increase in the concentration and frequency of some fatty acids was observed, after an increment in the nutritional management of the animals, in addition to predominance of palmitic acid (C16:0) and oleic acid (C18:1- cis (n9)). The results indicate a significant improvement in the quality of the milk in the assessment period, due to the corrective actions that were established, and the standard plate count showed good agricultural practices as to milk sourcing and the hygiene of the materials, being below the limits required by NI 76. The buffalo milk produced by the herd at the Experimental Station showed physicochemical and microbiological results in accordance with the legislation, being a raw material to be explored in the prospection of derivative products.Keywords: Bubalus bubalis; buffalo; good agricultural practices; raw milk.
