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 F to Giza and El-Behera governorates were included in the present study. Fifteen of them were y 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<0.05) 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 f MCV, MCH and MCHC showed significant increase (P<0.05 and P<0.01) respectively. Significant; (P<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.
