Some studies on quail feeds and management

The main objective of this work is to evaluate the replacement levels of sunflower seed meal (SFM) (with or without supplemental enzyme) & Nigella sativa seed oil meal (NSOM) for soybean meal (SBM) in grower and layer Japanese quail diets.Results obtained seemed to justly the following conclusion:1- Using SFM up to 75 % (25.5 % of the grower diet) and 100 % (25 % of the layer diet) substitution for SBM in growing and laying Japanese quail diets had no adverse effect on growth and laying performance. While from an economical point of view, SFM could substitute SBM up to the rate of 25% (8.5 % of the diet) and 100 % (25 % of the diet) in growing and laying Japanese quail. The supplementation of optizyme at a level of 0.50 g / Kg feed is superior in promoting performance of growing and laying Japanese quail. Also, the same results were obtained by using optizyme (0.50g / Kg feed) with 25 % and 100 % substitution in growing and laying Japanese quail diets. Such practice may be of high economic value without any adverse effects on the performance in growing and laying Japanese quail.2- Substituting NSOM up to 44.12% of SBM (15.00% NSOM of the diet) and 60.00% of SBM (15.00% NSOM) in growing and laying Japanese quail diets had no adverse effect on their growth and laying performance.
