Abstract：The study aimed to investigate the effects of Atractylodes extract(AE)on the growth performance,meat quality,and serum biochemical indices of White-feathered broilers.A total of 450 one-day-old healthy White-feathered broilers were randomly divided into three groups with five replicates per group and 30 chickens per replicate(All male).The control group(CK group)was fed a basal diet,while the LAE and HAE groups were supplemented with 150 and 300 mg/kg AE in the basal diet,respectively.The test period was 42 days.The results showed that compared with the CK group,the body weight of 21-day-old White-feathered broilers in the HAE group was significantly increased(P＜0.05),and the body weight of 42-day-old in the LAE and HAE groups was significantly increased(P＜0.05).The average daily weight gain in the HAE group aged one to 21 days was significantly increased(P＜0.05).The average daily weight gain in the LAE and HAE groups at the ages of 22 to 42 days and one to 42 days was significantly increased(P＜0.05),while the feed to gain ratio in the HAE group was significantly decreased(P＜0.05).Compared with the CK group,the eviscerating percentage,pectoral muscle rate,and leg muscle rate in the HAE group were significantly increased(P＜0.05).The cooking loss and the 24-hour drip loss of breast muscles were significantly decreased(P＜0.05),and the pH24h value was significantly increased(P＜0.05).The 48-hour drip loss of pectoral muscles in the LAE and HAE groups was significantly reduced(P＜0.05).Compared with the CK group,the activities of serum superoxide dismutase and glutathione peroxidase,the content of high-density lipoprotein,and the total antioxidant capacity of broilers in the LAE and HAE groups were significantly increased(P＜0.05).The concentrations of low-density lipoprotein,malondialdehyde,and the activities of alanine aminotransferase and aspartate aminotransferase were significantly decreased(P＜0.05).The activity of serum catalase of the HAE group was significantly increased(P＜0.05).The study indicates that dietary AE supplementation enhances growth performance,slaughter performance,and serum antioxidant capacity in broilers,with 300 mg/kg identified as the optimal dosage.
