- Abstract
This study aimed to study the effects of adding Stems Leaves of Angelica sinensis (ASL) pow‐ der to the diet on the growth performance, slaughtering performance, serum biochemistry and antioxidant capacity of broilers. 432 broilers were randomly divided into 6 groups according to the test requirements, each group was set up with 6 replicates, each replicate of 12 chickens, fed with a diet containing ASL of 0 (group 1), 1% (group 2), 1.5% (group 3), 2% (group 4), 2.5% (group 5), 3% (group 6), respectively, the feeding test time was 42 days. The results showed that: compared with group 1, groups 3, 4, 5, and 6 significantly increased the average feed intake and average body weight gain of broilers in the later stage (22-42 days) and throughout the experimental period (1-42 days) (P<0.05); the addition of ASL in the diet significantly increased the slaughter rate of broilers (P<0.05). Compared with group 1, groups 4 and 6 significantly increased the semi clean bore rate, full clean bore rate, chest muscle rate, and leg muscle rate of broilers (P<0.05), and significantly reduced the abdominal fat rate of broilers (P<0.05); 4, 5 and 6 groups significantly reduced blood lipid level and blood sugar content (P<0.05), significantly increased serum glutathione peroxidase activity in broilers (P<0.05), and the total antioxidant capacity of serum in 6 groups was the highest. In summary, the addition of angelica stem and leaf powder to the diet improved the production performance, slaughtering performance, serum biochemical and antioxidant capacity of broilers, and the recommended addition amount is 3%.
