Nowadays, the interest in jennet milk has considerably increased worldwide due to its nutritional characteristics. This study aimed to analyse the main physicochemical and hygienic-sanitary parameters of some jennet milk samples, by using current methods of quality monitoring. The following physicochemical (dry matter - DM, non-fat dry matter - NDM, fat, total protein, β-casein, lactose, and cryoscopic point), metabolic (urea, acetone, and β-hydroxybutyrate - BHB) and hygienic parameters (total bacteria count - TBC, somatic cell count - SCC and differential somatic cell count - DSCC) were assessed. Additionally, electrical conductivity (EC), pH, temperature, and density were investigated. The results revealed variations of total DM (9.64-11.11%), which were mainly given by the NDM oscillations (8.62-9.54%) and to a lesser extent by the fat content (0.25-1.66%). The study also emphasized low values of EC (1.75 mS/cm), TBC (22.16-62.15x103 CFU/mL), and SCC (3-30x103 cells/mL). The good health status was also confirmed by other metabolic indices, such as urea (36.27 mmol/L), acetone (0.06 mmol/L), and BHB (0.14 mmol/L).
