Nicarbazin causes a more severe respiratory alkalosis at high temperature. Low chloride in the diet, high electrolyte balance of the diet, high potassium in all vegetable corn-soya diets and fever from infection will all increase the effect of this condition. Lowering the temperature to favor higher pCO2 levers and blood pH between 7.35 and 7.45 will all help in reducing mortality and geeting the bird to be more efficient in its energy usage (better feed conversion). Great work!
