| Abstract |
| This study was performed on 120 of 5-6 week old Japanese quail hens. They were divided into five groups after two week of adaptation. Treatments were as follows: G1 (control with basal layer quail diet), G2 (17%protien diet), G3 (500g protease/ton of 17% protein diet, G4 (500ml of formic acid /100 kg of 17%protein diet), G5 (0.05% protease + 0.5% formic acid of 17% protein diet). The experimental period was 12 week. For each replicate, daily egg number, daily egg weight and egg mass as well as weekly feed intake, egg production and FCR were recorded. At the end of each week, eggs were collected from each replicate to evaluate egg quality traits [shell weight (wt.) and %, shape index, egg yolk wt. and % and albumin wt. and %]. Mean egg production, shape index, egg albumin weight, egg shell weight and egg yolk percent in all treated low protein groups were as the control. Mean FCR was improved numerically in G3 (protease) when compared with the other. G3 was being the highest in T3 hormone than the other.G3 was being the highest in feed intake and body change weight. Triglycerides /whole yolk were lower in all treated low protein groups than the control. Cholesterol (mg)/whole yolk was low in low protein and protease groups. It could be concluded that, fed laying Japanese quail hen on an economical low protein diet contain 0.05% protease as feed additives significantly improve performance and reduce cholesterol (mg)/whole yolk. |
