Brine mineral water (BMW) is groundwater nearby the deep-sea and the mineral component of the BMW is different from the water of the deep-sea because components of the BMW are derived from unique surrounding geographical features. Recently, the BMW has attracted attention due to the composition of the unique minerals related to health, however, the influence of the BMW on physiological function is not yet determined in domestic animals. Therefore, this experiment investigated the influence of the BMW on growth performance, water intake, blood properties, and immunoglobulins level of serum in the growing-finishing pigs. A total of the 64 pig barrows (Landrace × Yorkshire × Duroc) with an average initial weight of 40.56 ± 0.17 kg were used in the experiment, and 0%, 2%, 3%, and 5% of the BMW diluted with freshwater were provided during the 56 days to experimental animals. We found that the gain/feed ratio in the 3% BMW group was significantly higher than in the 5% BMW group in the growing-finishing pigs (<italic>p</italic> < 0.05). The water intake was significantly increased in the 5% BMW group than other groups (<italic>p</italic> < 0.05) in the growing-finishing pigs. Also, the concentrations of the red blood cell, hemoglobin, and hematocrit were significantly higher in the 3% BMW group than in the control group. The level of high-density lipoprotein cholesterol was higher in the 3% BMW group than in the 5% BMW group (<italic>p</italic> < 0.05). Furthermore, immunoglobulin (Ig) G and IgM levels of the serum were significantly higher in the 2% and 3% BMW groups than in the control group (<italic>p</italic> < 0.05). These results suggest that dilution of the 3% BMW in the intake water could improve levels of red blood cells and serum immunoglobulins in the growing-finishing pigs.
