The Effect of Adding Different Types of Vegetable Oils and Waste Frying Oil on the Productive and Reproductive Performance of Japanese Quail

This study was carried out to evaluate the effect of adding different types of vegetable oils in improving production and reproduction performance and egg quality of Japanese quail. A total number of 112 birds of the 6-weeks Japanese quail were used and randomly distributed on four treatments with 4 replicates per 7 birds (2 males and 5 females). The bird were fed by treatments the following treatment: the first treatment (a control 2.5 % commercial oil (a mixture of soybean oil, sunflower oil and cotton seed oil)), the second (2.5% corn oil), third (2.5% sunflower oil), and fourth (2.5% waste frying oil -frying fish-(commercial oil)). Body weight (BW), body weight gain (BWG), feed consumption (FC), feed conversion ratio (FCR), egg production, egg weight, egg mass, fertility, hatchability, weight of chicks at hatch,  egg quality, and relative economic efficiency (REE) were estimated for the whole experimental period (10 weeks).
There was no significant effect on egg number, egg mass, egg laying rate, feed intake and FCR, except for egg weight, which was higher for birds fed sunflower oil and waste frying oil compared to the second group (corn oil). Lipid sources evaluated had no significant difference (p > 0.05) for yolk weight, yolk percentage, albumen percentage, eggshell percentage, shape index, yolk index, Haugh unit (HU), shell thickness and SWUSA between the treatments applied. However, albumen weight, eggshell weight, and width of egg increase significantly (P >0.05) due to addition sunflower oil compared with addition of corn oil, and increase significantly (p > 0.05) shell strength and ESA comparing corn oil group or control group. There were insignificant differences in fertility and hatchability rate between the experimental treatments. However, body weight of chicks at hatch increased significantly (p > 0.05)) due to addition sunflower oil comparing the other treats and increase significantly due  to  waste oil by  comparing the  control treat and corn oil treat. It was observed that treatment the quail birds with different types of vegetable oils have no significant effect on body weight of these birds during the experimental period. Replacement of commercial oil with waste frying oil has led to higher economical efficiency. However, addition of corn oil has led to lower economical efficiency.
