Abstract
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 1 st group was reared on standard ration (control), the 2 nd group was reared on standard ration and given orally Sesame seeds capsules daily (250 mg /kg) and the 3 rd 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 2 nd and 3 rd group compared with the control group. This was accompanied by a significant decrease in MCV and MCH. Significant increase in the MCHC in the 3 rd 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 2 nd and 3 rd 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 3 rd 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.
Highlights
Plant seeds and herbs are used for treatments of diseases in the folk medicine
The Sesame seeds in breeder diet enhances the erythropoiesis as shown by a significant increase in the red blood cells count (RBC) count, Hemoglobin concentration (Hb) and Packed cell volume (PCV) compared with the control group, and it was reflected in the signifant decrease in the Mean corpuscular volume (MCV) and Mean corpuscular hemoglobin (MCH), and the signifant increase in the Mean corpuscular hemoglobin concentration (MCHC), after 2 weeks of treatment, (Table 1) and after 4 weeks of treatment (Table 2)
Sesame seeds effects which enhances the blood picture represented by the increase in RBC, Hb and PCV, may be related to Sesame lignans which have an antioxidant and health promoting activities. [6], Sesame ingestion significantly increased the time for erythrocyte hemolysis due to the reduction of the thiobarbituric acid – reactive substances [13]
Summary
Plant seeds and herbs are used for treatments of diseases in the folk medicine. Their use was increased in many fields due to their safetyness and it’s low side effects as compared with chemical drugs [1]. Sesame seeds are rich in compounds with powerful antioxidant properties [6], it’s belongs to it’s lignan which consists of about 1.5 % of the sesame seeds or oil, the majority of which are sesamin and sesamolin [5, 7]. Sesame seed consumption appears to increase plasma gammatecopherol and enhance vitamin E activity which in turn prevent cancer and heart diseases [8]. Intestinal microflora convert lignans into Enterolactone and Enterodiol agents which are responsible for it's estrogenic activity [9]
