Abstract :

Subclinical and clinical hypocalcaemia (milk fever) are two major causes of economic loss in dairy cattle.At the onset of lactation, cows demand is 2.3gr calcium per kg of colostrum which is about nine times as muchcalcium as it is present in the entire plasma which could result in milk fever. The economic losses of milk feverinclude: milk fever relapses‚ downer cow‚ dystocia and reproductive disease.In this study effect of oral administration of calcium lactate bolus evaluated in a diary farm. Twenty four out of48 pregnant cows randomly selected and treated with calcium bolus at calving or 12 hours after calving, the restwas considered as control group. Blood samples were collected from cows at 24 and 48 hours after calving andanalyzed for serum total calcium level in both control and treatment group. Statistical analysis showed signifcantdifferences between control and treatment groups (p<0.05).
