An experiment was conducted at Department of Poultry Science, Veterinary College and Research Institute, Namakkal to study the effect of induced moulting on production performance of single comb White Leghorn hens at 80 weeks of age. Induced moulting was done by adopting the standard feed and water withdrawal method (Wolford, 1984). There is no mortality during induced moulting programme. The parameters were studied before and after moulting. During pre-moult and post-moult period the mean egg production was 55.57 and 74.20 per cent; shell thickness 0.22 and 0.31 mm and egg weight 53.74 and 54.29g respectively. The differences observed in each parameter were not statistically significant (P>0.01). From this study, It was concluded that there was no significant difference (p>0.01) in pre and post moult performance in White Leghorn hens at 80 weeks of age.
