Evaluation of subclinical hypocalcaemia and serum glucose correlation in postpartum period of dairy cow

Hypocalcaemia is a risk factor for many important diseases such as ketosis, in the lactation period. Hypoglycemia and hyperketonemia are the main metabolically disturbances in ketosis, which may affect the clinical syndrome. In most cases, the severity of clinical syndrome is related to the level of hypoglycaemia. The aim of this study was to evaluate the correlation between subclinical hypocalcaemia and serum glucose at postpartum period in a dairy farm with 2000 cattle in Tehran province. JOURNAL OF VETERINARY CLINICAL RESEARCH J.Vet.Clin.Res 2HM7-55 2011 Blood samples were taken from 1000 cattle; serum glucose and calcium were measured within the first 12 hours at 24 hours and 10 days postpartum. In this study, the prevalence of subclinical hypocalcaemia with the cutting point of 8mg/dl was 37,51 and 7 percent, respectively. For hypoglycaemia with the cutting point of 35mg/dl, the prevalence were 0,1 & 8 percent respectively. Based on statistical tests: hypocalcaemia cases showed decreased in mean level of serum glucose, to compare with the normal cases (P = 0.017). Calcium concentration in 10 days postpartum showed correlation with the serum glucose level at the same time (P= 0/0005).
