Abstract Chronic hypophosphatemia (milk lameness) is one of the most important metabolic disorders concerning dairy cattle. This study was conducted for evaluation of clinical situation and hematobiochemical status of lactating Holstein-Friesian cows that suffered from chronic hypophosphatemia in Egypt. A total number of twenty seven lactating Holstein-Friesian cows belonged to Giza and El-Behera governorates were included in the present study. Fifteen of them were apparently healthy and fed on concentrate mixture and roughage while twelve of them were suffered from pronounced lameness, peculiar slow creepy gait, stiffness, gradual decrease in milk yield and pica. Results showed significant (P≤0:0.05) increase in respiration and pulse rates in affected cows. Also, there was significant (P≤:0.001) decrease in the levels of hemoglobin, PCV, and RBCs count while MCV, MCH and MCHC showed significant increase (P≤0:0.05 and P≤0.01) respectively. Significant (P≤0.05:0.001) increase was recorded in the levels of serum BUN and potassium while there was significant (P≤0.001) decrease in the level of serum inorganic phosphorus in cows with milk lameness. This data is one of few records about chronic hypophosphatemia (milk lameness) in Holstein-Friesian dairy cows among Egypt.
