Abstract: 

This study was conducted in Animal House Research Center at University of Aleppo on a flock of Inbred local quail 180 birds during year 2021. In order to study the effect of adding Roselle (hibiscus) to drinking water at specific rates (2-1%) on indicators of egg production and quality in color groups (creamy , striped, and Black) from local quails bred by the inbreeding method (third generation F3). The results of the study showed a significant improvement in the parameters of egg production (egg weight EW, number of eggs EN, egg mass EM), and internal egg quality (shape index, yolk index, Haugh units).  when adding hibiscus at 2% to the water of local black and striped quails and cream, and it was found that adding hibiscus by 2% to drinking water recorded the lowest average weekly feed consumption amounted to 176.42 g/bird/week, and the best feed conversion factor was (2.74) g fodder to produce 1 g eggs during the production period

Key words: local quail, inbreeding, Roselle (hibiscus), Egg Production, internal egg quality, Third Generation F3.
