Objective: The incidence of the post parturient hemoglubinuria (PPI-1) in the cattle population is very low, and usually only one or two cases will be seen at one time in an individual herd. In Shahrekord area, between June and July 2000, 15 cases had been observed suffering from PPH.
Design: Field study and sample survey.
Animals: Fifteen parturient dairy cattle suffering from PP[-1.
Procedure: Clinical signs were noticed and blood samples were taken from jugular vein of PPH cows, for measuring the levels of calcium and phosphorus.
Statistical analysis: Descriptive statistics.
Results: Serum levels of calcium and phosphorus were as 8 2±0.45 and 2.85±0.31 mg/dl, respectively.
Clinical implications: Some epidemiological aspects such as; decrease rainfall (approximately 7% less than last year), warm weather (approximately 0.5c higher than last year), decrease roughage quality, primary selenium and secondary copper deliciency (1) and hypophosphatemia (13) may interfere with evidence of postparturient haemoglubinuria.
