Abstract

This experiment was conducted to investigate the effect of feed restriction on egg production of laying Japanese quail during the period from 6 to 14 wk of age. Four hundred and fifty Japanese quail chicks were divided into five groups. Each treatment group contained three replicates of 30 birds (20 females + 10 males) each.   Layers were reared in brooder batteries. Treatments were assigned as follows:. T1, layers fed 100% of daily feed intake requirement (control) T2, layers fed 90% of daily feed intake requirements, T3, layers fed 80% of daily feed intake requirements, T4, layers fed 70% of daily feed intake requirements and T5, layers fed 60% of daily feed intake requirements. Feed intake, egg number and egg weight were recorded. Egg mass and feed conversion ( g feed / g egg mass ) were then calculated. Results showed that increasing feed restriction negatively affected (P<0.01) body weight compared with the control. At the age of 6 wk, hens receiving 80, 70 and 60 % of the recommended feed intake laid no eggs , while at  wk 7, hens that received 60 % feed intake still laid no eggs . However, hens fed 90% of the recommended feed intake quail eggs equal (P<0.05) to that of the control group. Egg mass values trended to agree with both egg number and egg weight as expected.  Birds subjected to severe feed restriction in early life showed lower quality of albumin and yolk compared to those given feed ad libitum. Total economic costs declined as the level of restriction increased. Net revenue, economical efficiency and relative economic efficiency values were lower in treatment groups except the group of birds fed 90% of the requirements as they showed higher values and surpassed the ad lib control one .
