This experiment aimed to study the influences of drinking saline well water and the alternation with fresh tap water every week as one of the bio-stimulation methods to reduce the harmful effect of drinking saline water on hematological parameters, productive and reproductive performance of V-Line doe and buck rabbits. A total number of 48 old 5 months old (30 does, body weight of 2955.0 ± 32.6 g and 18 bucks, body weight of 2850.0 ± 31.2 g) of were used in this experiment. Rabbits were randomly divided into three equal groups (10 does and 6 bucks of each). Rabbits of the 1st group (G1) considered as control group (drank tap water, 301 ppm TDS), rabbits of 2nd group (G2) drank saline well water (5568 ppm TDS) and rabbits of 3rd group (G3) drank saline well water followed with drank fresh tap water every week until the end of experiment. The results demonstrated that values of red blood cells, white blood cells and hemoglobin decreased (P<0.05) in the rabbits of G2 group when compared to G1 group. However, no significant differences in the white and red blood cells and hemoglobin were observed among the rabbits of G3 and two other groups. In contrary, Hematocrit (%) increased (P<0.05) in doe and buck rabbits of G2 and G3 when compared to G1 group. Total protein, globulin and glucose concentrations of rabbits drank saline water (G2) decreased (P<0.05) in does and bucks as compared to G3 group. Rabbits of G3 showed insignificant increase in glucose concentration by 9.6 % comparing with G2 group. Cholesterol and total lipids concentrations were significantly increased in the does and bucks of G2 as compared to G1 group. Doe and buck rabbits of G2 showed increased (P<0.05) alanine transaminase and aspartate transaminase concentrations as compared to G1 and G3 groups. Drinking well water (G2) increased (P<0.05) concentrations of calcium, sodium and chloride in the rabbits compared to G1 and G3 groups. However, phosphorus and potassium concentrations were significantly decreased in the rabbits of G2 as compared to other two groups. Aldosterone and triiodothyronine hormones decreased (P<0.05) in the rabbits of G2 than that of G1 and G3 groups
