This study was aimed to determine the influence of Oregostem® and imbalance diet on body performance, hematology and spermatogenesis of male quails. A total of 160 birds have been distributed into four groups (40 birds) each with 2 replicates starting at 12 weeks of age, the four treatments includes:(G1) was fed on balanced diet only. (G2) was received a balanced diet with Oregostem® with drinking water. While G3 was fed on imbalance diet (ground yellow corn) and G4 received imbalance diet with Oregostem®. The parameters including body performance, reproduction, blood and biochemical Figure and histology of testes were measured at 4th and 8th weeks from beginning of treatment. The results showed that the supplementation of Oregostem® caused a significant increase in body and right testis weight, gonadosomatic index, sperm count as well as live sperm in G2 relative to other groups at 4th and 8th weeks post treatment. In G3, WBC and lymphocytes decrease significantly with increasing hetrophils percentage and stress index at 4th and 8th weeks post treatment. Also there was a significant decrease of cholesterol with an increase of total protein and creatine kinase in G3 at 8th week of treatment. While the groups treated with Oregostem® did not differ from control group. This study concluded that liquid form of Oregostem® had a positive effect on body weight, sperm count with improvement hematological and biochemical parameters of the male quails.
