AB  - This study was designed to evaluate the effects of Dietary Electrolyte Balance (DEB = Na<SUP>+</SUP> + K<SUP>+</SUP>- Cl<SUP>-</SUP>) on the performance and eggshell quality of layers in their late laying period. Two hundred fifty six Hy-Line strain laying hens, 55-65 of age, were randomly assigned to 4 dietary treatments. The DEB levels were 0, 120, 240 and 360 mEq kg <SUP>1</SUP> and were obtained by addition of NaCl, NaHCO<SUB>3</SUB>, KHCO<SUB>3</SUB> and NH<SUB>4</SUB>CL as needed. Egg production, feed intake, egg mass and Feed Conversion Ratio (FCR) were not significantly affected by any of the treatments, whereas eggshell quality was significantly affected (p< 0.05). The shell thickness were increased with increasing DEB from 120-360 mEq kg <SUP>1</SUP> relative to the control diet. It was concluded that high rate DEB (360 mEq kg <SUP>1</SUP>) can improve eggshell quality in the late laying period.
