Hypocalcaemia is a risk factor for many important diseases such as ketosis, in the lactation period. Hypoglycemiaand hyperketonemia are the main metabolically disturbances in ketosis, which may affect the clinical syndrome. Inmost cases, the severity of clinical syndrome is related to the level of hypoglycaemia. The aim of this study was toevaluate the correlation between subclinical hypocalcaemia and serum glucose at postpartum period in a dairy farmwith 2000 cattle in Tehran province.Blood samples were taken from 1000 cattle; serum glucose and calcium were measured within the frst 12 hours at24 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 thenormal cases )P = 0.017(. Calcium concentration in 10 days postpartum showed correlation with the serum glucoselevel at the same time P= 0/0005.
