[Methemoglobinemia in calves with emphasis on the dam-calf relationship and after experimental administration of nitrates].
A field investigation of methaemoglobinaemia was performed in healthy calves and in calves suffering from diarrhoeas at different age periods; methaemoglobinaemia of dairy cows and their newborn calves was examined at the average age of 2.5 days. In the other part of this study, NO-3-ion was administered experimentally per os to the calf organisms at doses of 0.15 and 0.3 g KNO3.kg-1 liveweight; this treatment induced a low to medium degree of clinical methaemoglobinaemia. The results of this study indicate that it is possible to comment on the physiological standard of methaemoglobinaemia (less than 3% MaHb) in the total haemoglobin, urgent time of methaemoglobin detection after nitrate intake (2 to 8 h) with respect to the fast dynamics of nitrates, and the importance of subclinical form of methaemoglobinaemia and its relationship to the ontogenetic development of piglets.
