The Degrees of Parturient Hypocalcemia and Its Relevance to Other Metabolic Profile Parameters in Downer Cows
At calving time, the cows were monitored and blood samples were taken from jugular vein of 38 cows with parturient paresis and 38 healthy ones. The levels of calcium, phosphorus, magnesium, sodium, potassium, chloride, glucose, triglyceride, cholesterol, albumin, globulin and A/G ratio were assessed to find the correlation between the degree of hypocalcemia and other parameters. According to ca...

1 Interpretative Summary: Effect of oral calcium supplementation on early lactation health 1 and milk yield in commercial dairy herds. By Oetzel and Miller, page 000. Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into contro...
متن کاملDiet-induced pseudohypoparathyroidism: A hypocalcemia and milk fever risk factor.
Subclinical hypocalcemia may affect half of all multiparous cows, and clinical hypocalcemia or milk fever affects approximately 5% of dairy cows each year. This disorder of calcium homeostasis can be induced by several dietary factors. Recent studies implicate high dietary potassium and high dietary cation-anion difference (DCAD) with increased risk of milk fever. The hypothesis tested in this ...
متن کاملHypocalcemia and pregnancy-induced hypertension produced by low-calcium diet.
Recent studies from our laboratory in fasting pregnant ewes with twin gestation have implicated low serum calcium concentration in the etiology of hypertension in pregnancy. We hypothesized that the reduction in serum calcium concentration produced by feeding of a calcium-deficient diet in twin gestation would lead to a significant increase in maternal arterial blood pressure, vascular resistan...
