摘要： The passion fruit peel (PFP) is the by-product of juice processing and is rich in phenolic com-pounds and dietary fibers. As the high ADF content in PFP (34.20%), we proceeded to treat PFP with cellulase. The ADF decreased to 16.70% after enzymatic processing, and we supposed that enzymolytic passion fruit peel (EPF) should have a greater growth performance than PFP to broilers. Two trials were conducted to evaluate the effects of dietary PFP or EPF supplementation on growth performance, serum biochemical indices, meat quality, and cecal short-chain fatty acids, microbiota, and metabolites in broilers. In Exp. 1, 180 1-day-old Sanhuang broilers (male, 36.17 +/- 2.47 g) were randomly allocated into 3 treatments, with 6 replicates in each treatment. The 3 experimental diets included 1 basal diet (control) and 2 PFP-added diets supplemented with 1 and 2% PFP, respectively. The trial lasted for 42 d. In Exp. 2, 144 Sanhuang broilers (male, 112-day-old, 1.62 +/- 0.21 kg) were randomly allocated to 3 treatments. Each treatment was distributed among 6 pens, and each pen contained 8 broilers. The 3 treatment diets included: a control diet, a positive control diet supplementing 75 mg/kg chlortetra-cycline, and the experimental diet supplementing 3% EPF. The trial lasted for 56 d. Results showed that dietary 1 and 2% PFP addition did not affect growth performance in Exp. 1, and the 3% EPF supplementation had a nega-tive effect on ADFI (P < 0.05) in Exp. 2. A decreased serum triglyceride (P < 0.05) in broilers was observed in Exp. 1. Broilers fed EPF had a higher glutathione peroxi-dase (GSH-Px) (P < 0.05), and lower levels of tumor necrosis factor -a (TNF-a) (P < 0.05) and glucose (P < 0.05) in Exp. 2. We also found that broilers from PFP or EPF-treated treatments had an increased butyrate con-tent and higher microbial diversity in the cecum. The effects of antioxidation, anti-inflammatory function, and elevated SCFAs were confirmed after the microbe and untargeted metabolomic analysis. Dietary EPF supple-mentation significantly increased the SCFA-generating bacteria, anti-inflammatory-related bacteria, the antioxi-dant-related and anti-inflammatory-related metabolites. Moreover, dietary 3% EPF addition positively affects the biosynthesis of phenylpropanoids, which strongly corre-late with the antioxidant and anti-inflammatory proper-ties. In conclusion, the proper addition level did not affect the growth performance, and the PFP and EPF could improve the antioxidation state, anti-inflammatory activ-ity, and intestinal functions of Sanhuang broilers to some extent.
