title: [Influence of age, pregnancy and lactation on serum calcium, inorganic phosphate and alkaline phosphatase in the Gobra zebu].
abstract: Serum concentrations of two minerals (Ca, P) and activity ol ALP of 368 Gobra Zebu of breeding centre of Dahra have been measured. Blood samples were taken from groups of zebu of varying age (< 1 month to 3 years) and physiological status (pregnancy, lactation). Concentrations of Ca, P and activity of ALP hither on young animals are related to the needs of bone growth. Concentrations of these constituents in serum decrease with advancing age. On early pregnancy calcemia decreases because Ca is extracted towards the fetus, while phosphatemia decreases strongly on late pregnancy. Activity of ALP changes during pregnancy, but does not appear to be correlated with any stage of pregnancy.
