Effect Quercetin on Physiological and Productive Performance of females quail exposed to oxidative stress induced by H2O2
Plant polyphenols, particularly flavonoids, are of graet intrigued due to their wide run of natural activities. Quercetin, an omnipresent flavonoid, is known to have antioxidant and antibacterial impacts. The aim of this experiment is to know the effect of adding different levels of quercetin on some productive and physiological Traits of normal and oxidative stress quail birds. In the study, (108) females quail at the (45 days)of age, randomly distributed into six treatments, with three replications per each and reared for (42 days). The experiment treatments, as follows: The first treatment (T1): control group and the second treatment (T2): the birds fed a standard diet and drinking water with hydrogen peroxide (0.01% H2O2 ), the third(T3) and fourth(T4) treatments :The birds fed a standard diet with (400 and 600 mg of Quercetin / kg feed) respectively, normal drinking water. About the fifth (T5) and six (T6) treatments,the birds consumed same as T3 and T4 diet except for supplemented drinking water with (0.01% H2O2).The results indicated that the addition of quercetin to diets of quail birds led to:Significant improvement in the production Traits of natural and stressful quails by increasing egg production rate. Significant improvement of some biochemical indicators in the blood serum of natural and stressful quails birds, such as Estrogen, cholesterol, total protein, globulin, Calcium, AST, ALT, Malondialdehyde enzyme and glutathione concentration. While it did not affect glucose and albumin concentration. In conclusion, our study present that quercetin has huge effect on production and physiological indicators in females quail.
