Study of the incidence of pregnancy toxemia by measuring some blood elements, metabolites and cortisol levels in Ghezel ewes

Pregnancy toxemia of ewes is a metabolic disease caused by glucose deficiency in mothers in response to rapid increases in fetal requirements. The objective of this study was evaluation of some blood elements and metabolites and cortisol levels in pregnant Ghezel ewes at Khalatposhan research station. In this study, blood samples were taken from 50 pregnant ewes at three times, before mating, during pregnancy and before lambing. Thereafter, glucose, calcium, phosphorus, urea and total protein levels were measured using the spectrophotometric method and blood cortisol concentration using the Elisa method. The effect of parity on serum glucose concentration was significant (p
