Abu-TalebAbstractA feeding trial was conducted to study the effect of replacing yellow corn ingredient as the major energy source in laying Japanese quail diets by 0, 5 and 10% each irradiated Olive Pulp (IOP) or un-irradiated Olive Pulp (OP). A total of 216 laying Japanese quail, 12 weeks-old were randomly divided into six equal treatments (36 birds/treatment) with three replicates (8 female, 4 male in each). The experiment was lasted for six weeks to evaluate OP or IOP as a source of nutrients. The results obtained could be summarized as follows: 1). There was a significant (P ≤ 0.05) increase in egg production, egg weight and feed efficiency, fertility, hatching percentage and hatching weight when IOP was fed at levels up to 10%. 2). There was a significant (P ≤ 0.05) increase in blood heamalotogical parameters when IOP was fed at levels up to 10%. 3). OP had no significant effect on egg quality measurements, except for yolk weight % and yolk colour values, they recorded significant (P ≤ 0.05) increase in diets including IOP up to 60 g/kg. 4). It seems that replacing of IOP up to 10% in layers diets had the highest relative economic efficiency. Therefore, it could be concluded that IOP can be used in laying quail diets at levels up to 10% on the expense of dietary yellow corn without detrimental effects on th...
