Post-moult egg number (5.57 +/- 0.52), egg weight (66.78 +/- 5.41 g), and shell thickness (0.39 +/- 0.04 mm) were significantly higher in birds which were subjected to the induced moult. Among the moulted groups the maximum number of eggs (5.80 +/- 0.48) was produced by the birds given corn during the moult, whereas the maximum egg weight (68.30 +/- 5.58 g) was noted in birds which were given ration No. 3 (16.5% crude protein (C.P.) and 2850 (Kcal/kg) metabolizable energy (M.E.)). Shell thickness was greatest (0.41 +/- 0.04 mm) in birds which were treated with the restricted diet during the moult. Post-moult yolk index, Haugh units and meat spot values did not shown any significant variations between the groups.
