The effects of different levels of phospholipid supplement and oil source on performance and blood biochemical parameters of Japanese quail

The present study was conducted to evaluate the effects of different levels of phospholipid supplement and oil sources on performance and blood biochemical parameters of Japanese quails. A total number of 270seven-day-olds Japanese quails were selected, and analyzed in a completely randomized design with 9 treatments, three replicates and 10 quails per each replicate. Experimental diets included: basal diet with 3 levels of phospholipid supplement (0, 0.1 and 0.2%) with 3 oil types (poultry, rapeseed, mixed of poultry and rapeseed). Results showed neither feed intake nor feed conversion ratio were not influenced by the type of oils. Using oil with phospholipid caused reduction in body weight and feed intake however increment in feed conversion ratio (p<0.05).Using poultry oil with/without phospholipid supplementation (0.1%) significantly increased breast and thigh weights in quail’s (p<0.05). Poultry oil with phospholipid supplement showed a significant effect on blood parameters, so that the levels of HDL increased but did not show significant effect with poultry oil and without phospholipid on cholesterol and triglyceride levels. The most neutrophil count was related to treatment received rapeseed oil with 0.1% phospholipid supplement. Overall, the use of poultry oil with phospholipids supplement improved carcass traits and positively affected blood and hematological parameters in Japanese quails.
