520			_aThe aim of this study was to investigate the effect of the dipping hatching eggs in ascorbic acid (AA) concentration on hatchability traits and chick weight and quality at hatch. A total number of 3600 fertile Sinai hen's eggs were used in factorial experimental design (2x 4 x 6). The factors were, dipping day (the 12th and 18th day), dipping time (1, 2, 3 and 4 min.) and ascorbic acid (AA) concentrations (0.0, 5.0, 10.0, 15.0, 20.0 and 25.0 g /liter distilled water). Results indicated that hatchability (%) was significantly (P≤0.01) improved as a result of dipping eggs at the 12th day of incubation period as compared to those dipped at the 18th day. Also, it was significantly improved by dipping eggs for 2, 3 or 4 minutes than those dipped for 1 minute. Dipping time for 3 minutes recorded the best hatchability percentage than those dipped for the other times. Moreover, hatchability (%) was significantly (P?0.001) improved by about 2.64, 3.87, 8.77, 2.65 and 2.55 % for eggs dipped into 5.0 , 10.0 , 15.0 , 20.0 and 25.0 g AA/ L solution as compared with those dipped into distilled water (0.0 g AA/L), respectively. Embryonic mortality (%) was significantly (P?0.01) decreased by 23.36 % for eggs dipped at the 12th day than those dipped at the 18th day of incubation period. Eggs dipped for 2, 3 or 4 minutes had significantly (P?0.01) lower embryonic mortality than those dipped for 1 minute. Also, it was significantly (P≤0.001) decreased by dipping eggs into 5.0 up to 25.0 g AA/L solutions than those dipped into distilled water (0.0 g AA/L). The lowest embryonic mortality was occurred by dipping eggs into 15.0 g AA/L solution comparing to those dipped into other AA concentrations. Key Words: Ascorbic Acid, Dipping Day And Time, Incubation Period And Hatchability.
