This study was carried out in the sheep field of the Department of Animal Production / College of Agriculture - Tikrit University for a period from 25/10/2021 to 2/1/2022 (70 days), preceded by a 14-day preliminary period to acclimatize the lamb to concentrated feed. In the sixteenth month, Awassi lambs aged 4-5 months were used from local trade, the initial weight was adjusted (25.350 ± 2.25) kg, the experiment was divided into two periods (0-35 days, 36-70 days) respectively . Study The results of this study are as follows: There are significant differences in efficiency for the second, third fourth and treatments (P≤0.05) on the first treatment. food conversion. It was in those qualities. Adding a mixture of (Cr-Met and Zn-Met) led to a significant (P≤0.05) increase in insulin concentration over the rest of the treatments, while the first treatment recorded a significant (P≤0.05) increase in cortisol concentration in lambs’ blood over the rest of the treatments. Significantly (P≤0.05) the two treatments (T2 and T3) over the rest of the treatments in the concentration of thyroxine (TSH), and the addition of Cr-Met recorded a significant increase (P≤0.05) over the rest of the treatments in the concentration of thyroxine (T4). It was noticed a significant decrease (P≤0.05) in the treatments (T2, T3, T4) compared to the control treatment (T1) in the concentration of threonine (T3). The length of the treatment period and the interaction between the periods and the treatments had a significant effect on these characteristics.

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.
