The present study has been aimed to determine the positive effects that can be detected by Apium graveolens seed on some physiological parameters in broiler breeder roosters (Hubbard flex). Thirty roosters, Twenty-sex weeks age, were randomly divided into three equal groups. First group (control) fed on the standard provender along the experimental period (7 weeks), second group (T1& T2) fed on standard provender supplemented with 2.5 & 5 Kg/Ton of fed, respectively. At the end of experiment, blood samples were obtained from wing vein for estimation of glucose, total cholesterol, total protein, LH, FSH, and Testosterone concentrations in blood serum. Then, roosters were sacrificed and the testes and Epididymis obtained for histological measurement. The result revealed that Apium graveolens seed supplementation in the two treated groups caused a significant increase (P<0.05) in body weight, weight, width & height of testes when compared with control group. On the other hand, serum concentration of glucose and cholesterol showed a significant decrease (P<0.05) in the two treated groups compared with control. The result of total protein showed a significant increase (P<0.05) in two treated groups compared with control. At the same time, the result of sex hormones, revealed a significant increase (P<0.05) in Luetinizing, Follicle stimulating & Testosterone hormones concentration in the both T1 and T2 groups compared with control.
