Abstract
Molt was induced on 4000 Hy-line (2000 hens at 17 months of age, the younger group. aod 201)0 hens at 19 months of age. the older group), II was carried out during the period from September 2002 to March 200") in the Poultry Research Station. Poultry Departrnent., Faculty of Agriculture F ayoum University The induced molt treatment included 4 days feed wrlhdr awal period and no water at the fourth day only (allowed by different periods (or 7.7,7,26.4 days which in them each hen was received 40 g feed ( 15 % crude protein) , 60 g ( 15% crude protein ) . 60 g ( 15% crude protein) .60 9 ( H% crude protein) BO 9 ( 17% crude protein) and 100 g (1,'% crude protein ) . respectively Reduced duration of day light during the treatment as follow: 8 hours I day at the first month then the light period was gradually increased to 17 hours /day at the second month, Carrying out induced moiling at 17 months age resulted in a reduction in mortality rate. increased egg production , improved feed conversion and reduced body loss during the treatment. on the other hand, appl'ying induced moiling al i9 months of age increased egg weight as compared with the 17 month of age, The economical efficiency was higher when the hens were subjected to induce matting at earlier age (17 months of age),
