In a study with 12 calves on milk nutrition, the course of methemoglobinemia as well as ttansrenal passage ofnitrates and nitrites after single per os administrations of 4 g NaNO2 per animal and 30 g KNO3 per animal in theform of water Solutions has been observed. The response of the organism of calves to per os administered dosesof sodium nitrite and potassium nitrate was observed by the determination of tlie methemoglobin percentage inblood and the nitrate and nitrite content in urine before the administration ofthe respective dose and after h 1, 2,3 and 4 after the administration. A significant elevation in the values of methemoglobin was recorded after h 2after the administration of 4g NaNO3 per animal. The mean value of methemoglobin in blood was 18.84% oftotal hemoglobin. A slight decline in the values occurred as early as after h 3 after the administration. Of clinicalsigns, cyanosis of visible mucosae was observed. The highest nitrite and nitrate values in urine were determinedafter h 2 after per os administration of 4g NaNO2, With the administration of 30g KNO3 per animal, the mostpronounced elevation in methemoglobinemia was observed after h 3, when the means values of methemoglobinwas 11,75%. Of clinical signs, only slight cyanosis of mucosae was detectable. Maximum values of nitrates inurine of experimental calves after h 3 after the administration of 30 g KNO3 per animal, with the mean value of29,9 mM NO3−1 clearly demonstrate a good transrenal passage of nitrates in calves on milk nutrition
