Abstract
A total of 144 Sina-laying hens aged 24 wks. were randomly dis­tributed into 6 groups. Each group was divided into three replicates. The first group received a commercial layer diet containing 17.5% CP. and 280 K cal ME/Kg and served as a control (T1). Other groups were fed a diet supplemented with 0.1, 0.2, 0.3, 0.4% Egg plus (E.) and 0.125% Fermacto 500 (F), respectively. The experimental diets were used from 24 till 48 wks of age. Results showed that using 0.3% E' (T4) improved the average of egg production percentage (EP%), egg mass (EM), feed conversion (FC) and economic efficiency (EEF). The dietary treatments didn't affect neg­atively on the average egg weight (EW), egg quality, serum total lipids and cholesterol. However. feed intake (Fl) was decreased either by in­creasing the level of E' or by the presence of F, accordingly, feed con­version improved. Eiher Egg Plus or Fermacto - 500 could be used as an effective promoters for egg production.
