Abstract

Six weeks feeding trial investigated the effect of different oil sources without or with lecithin supplementation on the productive, reproductive performance and egg quality parameters of laying Japanese quail. Quail hens were divided into 8 groups including; group 1, 2, 3 and 4 which were fed on the basal diet (BD) containing 2 % soybean, sunflower, palm and coconut oil respectively while groups 5, 6, 7 and 8 had the same previously mentioned design with lecithin addition. Feeding on coconut oil significantly reduced the egg production %, egg mass and deteriorated the FCR compared to other oil sources. Saturated rich oil sources (palm and coconut oils) induced higher embryonic mortality than the unsaturated oil sources. In conclusion, different oil source can affect productive, reproductive performance of laying Japanese quail. The saturated rich sources (palm and coconut) showed adverse effects on the productive (reduced egg mass and egg production, deteriorated FCR) and reproductive performance (increased embryonic mortality, lowered the fertility and hatchability). The sunflower oil showed good results regarding the productive and reproductive aspects if being used to replace the soybean oil in diets. Lecithin supplementation had no significant effect on the most of assessed parameters; however, its positive effects were shown when added with the palm and coconut oils.
