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. | ||||
