Metabolic hypophospathemia (postparturient hemoglobinuria PPH)

1-Phosphorus Supplementation (Essential)

-   IV sodium acid phosphate: Provides rapid correction

-   Oral phosphorus salts (dicalcium phosphate, monosodium phosphate)

-   Maintain serum levels after IV therapy

2-Antioxidants

• Vitamin C
• Vitamin E and selenium

3-Supportive Care

• Blood transfusion in severe anemia (after cross-matching blood testing)
• High-quality diet with adequate phosphorus
• Fluid therapy for dehydration or renal compromise

Prevention and Herd Management

Nutritional Management

• Ensure 0.35–0.45% phosphorus in lactation diets
• Maintain Ca:P ratio at 2:1
• Avoid prolonged feeding of phosphorus-deficient crop residues like barseem

Supplementation Strategies

• Free-choice mineral licks
• Concentrates fortified with P
• Pasture fertilization in deficient areas

Prognosis

• Good if treated early
• Poor to guarded if severe hemolysis and renal damage occur
• Chronic phosphorus deficiency in the herd may lead to recurrent cases
