| Abstract | ||||
| This research was carried out to determine the use of oil waste ((acidulated soapstock (AS) and distillated fatty acids (DFA)) as a replacement of various traditional oil sources (soybean oil (SO) or palm oil (PO)) in the diets of laying Japanese quail and their influences on productive performance, carcass traits, egg components and quality characteristics. At 16 weeks of age, 160 laying Japanese quail were distributed into four groups (40 quail each). Each group contained 4 replicates of 10 quail each. The first group was feed the basal diet containing (3%) SO as a fat source (control), while the groups T1-3 received basal diets with (3%) of (PO, T1), (AS, T2) and (DFA, T3) respectively. The experimental period was extended for 12 weeks. The result obtained revealed that: Layer quail fed diets containing (DFA, T3) improved Productive performance (egg production rate %, feed conversion ratio (kg feed /kg egg) and egg mass comparable or better than other treatments T1-2 and control. Carcass traits indicated that oil wastes (AS and DFA) or traditional oil sources (SO and PO) hadn’t effect on carcass characteristics (inedible and edible parts %) Similar trends were observed the effect of dietary treatment on egg quality (shell weight %, eggshell thickness (mm), shell weight unit of surface and shell density), on the other hand quail fed (DFA, T3) diet gave the lowest significant egg albumin weight% and shell surface area compare with other treatments. The different fat sources (SO, PO, AS and DFA) supplementation to the quail diets was effective on fatty acid composition of egg yolk. Conclusion: It is observed that the best performance was seen when 3% DFA supplementation laying quail diet without negative effecting on carcass traits, egg components, and quality characteristics. | ||||
