Evaluation of mineral metabolism of highly productive cows with myocardiodystrophy in the prenatal period

Mineral elements are necessary components of the cells and tissues body. The imbalance magnesium, potassium, phosphorus, calcium in blood serum animals affects function cardiovascular system, contributes development myocardial dystrophy. Due to intense functional activity, highly productive cows more prone this pathology, therefore, determination their content minerals during prenatal period is relevant. To perform study, two groups Kostroma breed third or fourth lactation, which - 10-13 days before calving, were formed under conditions livestock enterprise SPK "Gridino" Krasnoselsky district region. first experimental group was 15 clinically healthy cows; second included 5 with signs dystrophy (tachycardia, weakness heart sounds, specific ECG changes, etc.). amount important mineral for optimal determined serum, using OLVEX reagent kits. such as magnesium well total inorganic phosphorus mathematically calculated on he basis K:Mg Ca:P ratio. It found that sick level higher (1.85 times (P<0.001), against lower values potassium 29.57% (P<0.01), (by 10.9 %), 10.8%) than cows. This indicates a significant studied metabolism
