Plasma Insulin Concentrations in Parturient Cows

Oral Calcium Boluses for Parturient Dairy Cows

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...

Nutritional anestrus in beef cows: concentrations of glucose and nonesterified fatty acids in plasma and insulin in serum.

Twenty-two nonlactating Hereford cows exhibiting normal estrous cycles were fed either maintenance (M) or restricted (R) diets until most of the R cows became anestrus; R cows then were fed 160% of the M diet until estrous cycles resumed. Concentrations of progesterone, glucose, insulin and nonesterified fatty acids (NEFA) were determined in weekly blood samples. Blood also was collected freque...

Calcium chloride gel treatment of parturient dairy cows: Effect on hypocalcemia and parturient diseases

INSULIN REGULATES PLASMA GHRELIN CONCENTRATIONS in STREPTOZOTOCIN-INDUCED DIABETIC RATS

Ghrelin, an orexigenic peptide produced in the stomach has shown to elicit peripheral actions including regulation of pancreatic β-cell function. The aim of the study is to clarify the regulation of plasma ghrelin concentrations by insulin in streptozotocin (STZ) induced diabetic rats. Adult male Wistar rats were divided into control and three experimental groups as each group had 7 rats (n=28)...

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...
