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.
