الملخص EN

The study was carried out to investigate the effect of employing sesame seeds in broiler breeder diet on some physiological parameters.

30 Cobb breeder hens (36 week age) were divided into 3 groups (10 hens each).

The 1st group was reared on standard ration (control), the 2nd group was reared on standard ration and given orally Sesame seeds capsules daily (250 mg /kg) and the 3rd group was reared on standard ration and given orally Sesame seeds capsules daily (500 mg/kg).

The treatment continues for 4 weeks period.

Results showed a significant increase in the RBCs, Hb and PCV in the 2nd and 3rd group compared with the control group.

This was accompanied by a significant decrease in MCV and MCH.

Significant increase in the MCHC in the 3rd group compared with other groups after 2 and 4 weeks of treatment was noticed.

Sesame seeds treatments for 4 weeks also caused a significant increase in the WBC count in the 2nd and 3rd group as compared with control.

Hormonal Assay revealed that sesame seeds treatment with tow doses has no effects on plasma levels of LH hormone (4.94 and 4.48 miu/ml) compared with control (3.93 miu / ml), but the sesame seeds treatment (500 mg/kg) causes a significant increase in plasma levels of FSH (0.88 miu / ml) compared with the control (0.64 miu/ ml).

Sesame seeds treatment, also, increased the egg weight, shell weight and yolk weight and it reached the levels of significantly in the 3rd group (66.15, 7.33 and 20.65 g) respectively as compared with control (61.48, 6.86 and 18.66 g), respectively.

It is concluded that, sesame seeds treatment enhanced erythropoiesis, FSH activity and some productive parameters.
