Six hundred and sixty day‑old, unsexed, commercial broiler chicks were offered three types of simulated (on the pattern of composition of underground water in the state) brackish drinking water predominant in chloride, sulphate and bicarbonate salts at three levels of salt concentration, viz. 2000, 4000, 6000 EC. Each treatment had three replications with 22 chicks in each replicate. Eight weeks trial was conducted during summer (min. tern. : 9º to 24º, max. temp. : 24º to 42ºC, relative humidity : 50 to 75 per cent). The parameters studied were body weight gain, water intake, feed intake, feed conversion ratio, water to feed intake ratio, litter moisture content, leg deformities, and mortality upto eight weeks of age. At six and eight weeks of age, carcass yield, serum electrolyte composition (sodium, potassium, chloride, calcium and phosphorus), haematological studies (total erythrocyte count, total leucocyte count, haemoglobin and packed cell volume), differential leucocyte count (heterophil, lymphocyte, monocyte plus cosinophil and heterophil/lymphocyte ratio), scrum enzyme activities (glutamic oxalacetic tlans­aminase, glutamic pyruvic transaminase and alkaline phosphatase) and gross and histopathological changes in various treatments were studied.

The sulphate dominated water upto 2000, chloride dominated water upto 4000 and bicarbonate dominated water upto 6000 (S/cm) EC did not affect adversely any of the parameters studied. Heterophil/lymphocyte ratio, serum enzyme activities (glutamic oxalacetic and glutamic pyruvic transaminases), survivability, leg, deformity, and gross and histopathological parameters wore affected at 6000 EC level of chloride dominated and 4000 EC level of sulphate dominated water. The sulphate dominated water with 6000 EC level adversely affected body weight gain feed intake, water intake, feed conversion ratio, water to feed intake ratio, enzyme activities, survivability, leg deformity, heterophil/lymphocyte ratio and gross and histopathological parameters. It is concluded that broiler production may be safely adopted on the bicarbonate dominated water upto 600, chloride upto 4000 and sulphate dominated water upto 2000 (PS/cm) EC.
