The current work examined the impact of Ginkgo bilobaoil (GBO) on growth performance, some biochemical parameters, intestinal and hepatic morphology, economic efficiency and expression of some growth-related genes in broiler chickens. A total of 135 chicks (Cobb 500) were allotted into three groups with 3 replications (15 birds/replicate). The experimental groups included: G1 (control), G2 and G3 were supplemented with GBO in the drinking water (0.25 and 0.5 cm/L), respectively. The GBO was added to the drinking water only for 3 successive weeks. Compared to the other groups, supplementation with 0.25 cm/L GBO significantly (P≤ 0.05) increased final body weight, overall weight gain, feed intake and water consumption. When 0.25 cm GBO/L was added, that group significantly differed in intestinal villus length (P≤ 0.05). Birds received 0.25 cm GBO/L had significantly greater blood total albumin and total protein concentrations (P≤ 0.05), while birds given 0.5 cm GBO/L had higher serum cholesterol and LDL concentrations (P≤ 0.05). The cost parameters were significantly higher (P≤ 0.05) in the 0.25 cm GBO/L supplemented group, which exhibited higher total return and net profit. The addition of 0.25 cm GBO/L resulted in higher expression of antioxidant enzymes and insulin-like growth factor while inhibiting the expression of Myostatin in muscles (P< 0.05) compared to the control and those received 0.5 cm GBO/L. In conclusion, broiler chickens that received 0.25 cm GBO/L for 3 consecutive days per week had better performance, intestinal morphology, profitability, and antioxidant status than the control birds. |
