Effect of vitamin C supplementation on biochemical and enzymatic parameters was analysed in water deprived 18 2-3 years of local male Bakerwali goats during summer and winter seasons. In control group (n=6, for each season), water was offered ad-lib throughout the experimental period. Two treatment groups (T1 and T2) consisting of 6 animals each were selected. In T1 group, water was restricted and subdivided into 3 experimental periods: in period 1 (day 1 to 7), animals were adapted to water restriction regime by limiting access to water gradually from 15 to 3 hrs/day. In period 2 (day 8 to 14), animals had access to water for 3 hrs/day. In period 3 (day 15 to 22), animals had access to water only every second day for 6 hours. In T2 group, the same protocol as mentioned above was followed with the addition of vitamin C supplementation at a dose rate of 180 mg/kg b.wt./animal/day. Blood samples were collected on 1, 7, 14and 22ndday of experiments for the estimation of different biochemical and enzymatic parameters. In water deprived (T1) group, increasing trend (P<0.05) was seen in ALT, AST, ALP and ACP in blood. In T2 group, ALT, AST and ACP activity increased upto day 14 and then decreased on day 22. T1 value of serum enzymes were significantly higher (P<0.05) than vitamin supplemented (T2) group. Overall summer value of serum enzymes was higher as compared to overall winter values. Water deprivation had a negative impact on enzymatic parameters, which can be ameliorated by supplementation of ascorbic acid at the rate of @180mg/kg b.wt./day in goat during the heat and cold stress conditions.
