The toxic effects of saline drinking water on young turkey poults.

Turkey poults were offered ad libitum a diet containing 2.5 g salt/kg and tap water containing, 0, 90 or 105 mn NaCl to drink from 1 to 12 d of age. 2. High mortality with oedbema and ascites occurred mainly from 5 to 8 d in poults given the saline solutions. Mortality seemed to be related to salt and water intakes. 3. Plasma and body composition indicated abnormal retention of salt and water in poults younger than 12 d of age offered hypotonic saline. 4. In a second experiment using the same diet poults were offered hypotonic saline (105 mn NaCl in tap water) from 5, 9 or 13 d of age. High mortality with oedema and ascites was only observed when saline was given from 5 or 9 d. 5. The results suggest that from about 5 to 10 d of age there is a relative functional renal insufficiency which causes susceptibility to the toxic effects of saline water.
