ps at 35 d of age. The groups were fed either with normal caOne hundred and sixty healthy egg-type pullets wererandomly dividedinto two groulcium(Ca)(control,8.5 g Ca/kg) diet or with high calcium(HC,36.3 g Ca/kg) diet respectively.The experiment lasted for 32 days. The healthy situations of the egg-type pullets wereobserved. Blood gas values and serum and urine electrolyte content were determined.HC diet caused watery excreta in pullets. The pullets raised on HC diet hadsignificantly higher blood pH,HCO3-,BE and significantly lower blood PO2,PCO2,SO2 than the pullets raised on the control diet. Phosphorus and potassium decreased,meanwhile,calcium increased in the HC group as compared with the control group.Sodium,magnesium and chloride in serum had no significant difference between theHC group and the control. The pullets raised on HC diet had significantly higher urinepH than the pullets raised on the control diet. For HC pullets,urinary concentration and24-h urinary excretion of calcium and chloride was significantly higher,andmagnesium,inorganic phosphorus and sodium was significantly lower than that of thecontrol pullets. It is concluded that some metabolic disorders associated with highdietary calcium in egg-type pullets may be related to a state of metabolic alkalosis.
