The goal of the study was to evaluate resorbtion from the digestive tract and the clinical effect of a new calcium gel preparation, containing calcium chloride, kalium chloride, inorganic phosphorus, natrium dihydrophosphate, magnium chloride, carboxy-methylcellulose and benzoalkoniumchloride, for the prevention and treatment of parturient paresis in cows. Four experiments were carried out with 50 healthy and/or parturient paresis-prone cows that received the calcium gel preparation several times orally. The amount of calcium, inorganic phosphorus, magnesium and glucose was measured in the cows’ blood serum using Eos-Bravo analyzer and Hospitex reagents; the amount of 25-OH vitamin D was determined by means of the imunofermentation (IFA) method. Orally administered calcium chloride gel preparation is well taken up in the cows’ digestive tract, normalizes the amount of calcium, magnesium and inorganic phosphorus in cows’ blood serum, as well as protects the cows from developing parturient paresis. The preparation must be administered twice before parturition with a 24 hour interval and its third dosage must be administered at the time of parturition.
