The way to reduce harmful effect of combined feed containing nitrites (0.1 % of KNO2) on the body of broiler chickens by adding vitamin C above normal (50 and 100 mg/kg) is shown. Feeding such feed mixtures resulted in better growth of chickens and lower fodder consumption per unit of weight gain, lower concentration of methemoglobin (0.88-0.81 as against 1.02 %), higher content in blood of vitamins A (9115.8-114.8 as against 83.5 mkg %) and C (18.50-19.25 as against 17.51 mg/l), carotene (0.33-0.35 as against 0.31 mg %), as well as in somewhat higher concentration of vitamin A and carotene in liver. Addition of 100 mg of vitamin C per 11 kg of combined feed containing nitrites is economically justified.
