- Abstract
The levels of lactic acid, pyruvic acid and L/P index were studied during parturition in cows and calves. The results demonstrate various values of the metabolites studied in dependence on the length of parturient activity and on the way of finishing the parturition. The level of lactic acid increases with protracted parturient activity and that of puruvic acid decreases. Anesthesia applied at the traditional caesarean section hinders the course of fixed acids, which is reflected in the values of the L/P index. An excessive accumulation of fixed acids in mother's organism at the protracted parturition unfavorably influences the metabolism of fetus by means of the fetoplacental bed. Anesthesia does not affect the levels of the metabolites studied in calves. The values of the L/P index are in the same proportion as the levels of lactic and pyruvic acids are.
