Документ Lactation tetany in horses (clinical signs, treatment, prevention)(ВЦ НУБіП України, 2018) Borodynia V.І.; Lobodina L.S.The publication covers the clinical signs and flow of lactation tetany of horses, applied treatment of sick animals and prevention of this pathology. The degree of manifestation of clinical signs in lactation tetany corresponds to the concentration of ionized calcium in the blood serum of mare. For the mild form of the course of lactation tetany, the only sign of the disease may be increased excitability of the animal. In severe forms in sick horses there is a complex of typical clinical signs for hypocalcemic tetany. The amount of calcium in the serum in the initial stage of the disease, when the excitation of the animal is observed> 8 mg%; with the appearance of spasm signs - 5-8 mg%; lying position and numbness - <5 mg%. If there is no applying of timely treatment, the disease progresses with a mortal term within 24-48 hours. The preliminary diagnosis is based on data from anamnesis, clinical signs of the disease and response to specific treatment. The final diagnosis requires confirmation of low levels of ionized calcium in serum. For therapeutic purposes, for the mares is given intravenous introduction of calcium solutions, symptomatic treatment. Preventive measures are providing the sufficient amounts of calcium and phosphorus and their correlation in feed during the entire period of pregnancy and feeding the foals.Документ Lactation tetany in horses (milk fever, hypocalcemic tetany, transport tetany, eclampsia): distribution, etiology(ВЦ НУБіП України, 2018) Borodynia V.І.; Lobodina L.S.The publication covers issues of distribution and etiology of lactation tetany in horses. This disease occurs as a result of a disturbance of calcium metabolism in the mare's body. This pathological condition is associated with a sharp decrease in the level of ionized calcium in the blood serum, and sometimes with changes in the concentration of magnesium and phosphorus in it. Lactation tetany is a rather rare disease of horses. This pathology is diagnosed after a kidling with the onset of lactation, in the mares, when hypocalcaemia develops in organism of animal, after prolonged physical activity or transport (transport tetany), eclampsia. Signs of the disease are variable and associated with neuromuscular hyperresistibility. Lactation tetany is more likely to be affected by shire horse breeds. The mortality rate of animals is high and reaches more than 60%. Hypocalcemic tetany occurs in mare, which feeds the foal - on average 10 days after kidfling or 1-2 days after it is weaned. Mechanisms of hypocalcemia development in the mare's organism, which feeds the foal, consist of reducing the absorption of this element from the intestine, increasing its loss through the kidneys, sweat or milk (in the presence of lactation); or inhibition of osteolysis due to changes in the level of parathyroid hormone (parathormone), calcitonine or vitamin D, in stress states.
