The Influence of Pregnancy and Lactation on the Magnesium and Calcium Concentration in Goats’ Blood Serum

چکیده
The aim of this work was to trace differences in magnesium and calcium concentrations (both total and ionic form) between goats which were in late pregnancy and lactating goats. The study involved 30 goats. Blood samples were taken three times from each goat. Total concentrations of magnesium and calcium were determined with the colorimetric method and (A – 1.581 mmol dm–3; B – 2.052 mmol dm–3; C – 2.112 mmol dm–3). Ionic form of calcium based on using ion–selective analysis (A – 1.219 mmol dm–3; B – 1.126 mmol dm–3; C – 1.123 mmol dm–3). The study showed that mean value of both the total of calcium from each goat did not reach the reference level for this species. Ionic form of calcium was within the lever limit of the physiological norm. The content of magnesium in all the groups was within the range of reference concentrations (A – 1.051 mmol dm–3; B – 1.165 mmol dm–3; C – 1.117 mmol dm–3).

Background and Objective: Phototherapy is one of the therapy methods for jaundice caused by hyperbilirubinemia. Vitamin D and bilirubin have two distinct routes of metabolism yet part of their syntheses is common in the liver and thus they may influence each other’s synthesis. One of the consequences of phototherapy not previously studied in detail is hypocalcaemia and hypomagn...

To investigate uterine and serum Ca++ and Mg++ variations during the estrous cycle in the bovine, 66 genital tracts and blood samples were collected from Urmia abattoir, Urmia, Iran. The phase of the estrous cycle was determined by examination of the structures present on ovaries and uterine tonicity. Of the collected samples, 17 were pro-estrus, 12 estrus, 14 metestrus and 23 diestrus. The ute...
