Usefulness of calcium-magnesium products in parturient paresis in HF cows
Wydanie: 4 / 2010
The increased milk yield in dairy cattle has made it increasingly difficult to balance accurately the feed ration. This results in energy and mineral deficiencies as well as various homeostasis disorders including calcium and magnesium balance disorders, which in urn lead to metabolic disorders. In our study, we chose to assess the therapeutic efficacy of two most popular products of this type i.e. Glucalvet (Vetoquinol Biowet) and Antiparen-N (Vetoquinol Biowet). The study was conducted on 33 HF cows dipslaying symptoms of postparturient paresis that occurred between 2 and 4 day postpartum. The cows were divided into two groups: group A and group B, which were administered Glucalvet and Antiparen-N, respectively. Blood samples were taken twice from the jugular vein of each animal - just before and 24 hours after drug administration. The samples were used to determine serum concentrations of Ca, Mg, P, Cl and glucose. The average body temperature in both groups was slightly below normal and statistically significantly increased 24 hours after the intravenous infusion. The same tendency was observed for the pulse rate. The magnesium levels in the first group improved significantly after drug administration but its level was still lower than the physiological range. In the second group of animals, a slight drop in the Mg level after the Antiparen-N administration. Levels of Ca and P increased in both group of animals after the treatment. The average chloride concentration was similar for both assays. The serum glucose concentration increased significantly in both groups of animals after drug administration. Summing up, the study presented in this paper indicates that Glucalvet and Antiparen-N prove to be useful in the treatment of post-parturient paresis conditioned by Ca and Mg deficiency.
