title: [A case of nitrite poisoning in hens of medium weight laying parent stock].
abstract: As a result of a combined high temperature, almost complete calm, very limited ventilation, which was due to the secluded location of the poultry house, nitrite (NO2) poisoning occurred in the medium heavy layer parent stock. Nitrite and nitrate (NO3) had formed on and in hanging drinking containers, as NH3 dissolved in the drinking water and was converted into nitrite and nitrate. The feed intake decreased from 125 grams (ad libitum) to +/- 15 grams daily per bird. Egg production was reduced from 78 per cent to 0.5 per cent. Poisoning was associated with mortality of the hens. later on, the birds recovered completely.
