Effects of Bamboo Leaf Extracts on Blood Biochemistry and Antioxidant Function in Broilers at Early Age

This study was conducted to investigate the effects of dietary Bamboo Leaf Extract(BLE)on blood biochemistry parameters and antioxidant status in broiler chickens at early age,with purpose to improve the status of broilers and provide safe meat for human diet. A total of 256 1-day-old male Arbor Acres broilers were randomly divided into 4 groups with 8 replicate each. A CON was fed basal diet,while three experimental groups were fed basal diet supplemented with 0.10%,0.20% and 0.40% BLE for 21 d,respectively. The results showed that supplemented with 0.20% BLE significantly reduced total cholesterol and urea nitrogen contents in serum as compared with CON(P<0.05). Dietary of BLE had no significant effect on the antioxidant capacity of breast meat in broiler chickens,but improved glutathione concentration. The liver glutathione contents in 0.20% and 0.40% BLE groups were significantly higher than CON group(P<0.05),in addition,BLE improved liver superoxide dismutase and glutathione peroxidase enzymes activity. Compared with CON group,the serum glutathione peroxidase activity in broiler chickens was increased by 5.82% and 4.90% in the 0.10% and 0.20% BLE groups,respectively,among which the 0.10% BLE group was significantly higher than the CON group(P<0.05). In addition,the serum malondialdehyde contents in 0.10%,0.20% and 0.40% BLE groups were reduced by 11.18%,14.59% and 4.05% respectively as compared with CON group. In conclusion,adding a certain amount of BLE into broilers’ diets at early age without negative influence and improved health status and antioxidant capacity in broilers,which implied that Bamboo leaf extract act as food antioxidant had a certain feasibility.
