The aim of this study was to examine the effects of supplementing Guizhou black goats with Houttuynia cordata extract (HCE) during summer on growth performance, anti-inflammatory activity, and rumen fermentation parameters. A completely randomized single-factor experimental design was employed. Twenty-four healthy Guizhou black goats, with similar body weights (16.03 ± 0.79 kg), were randomly divided into three groups, with eight replicates per group and one goat per replicate. The control group (CON) was fed a basal diet, the LC and HC groups received the basal diet supplemented with 500 mg/kg and 1000 mg/kg of HCE, respectively. The ADG in the HC group was significantly higher (P < 0.05) than that in the CON group.The digestibility of DM in both the LC and HC groups was significantly higher (P < 0.05) than in the CON group. Additionally, the digestibility of CP, GE, and NDF in the HC group was significantly higher (P < 0.05) than in the CON group. GSH-Px levels in both the LC and HC groups were significantly higher (P < 0.05) than in the CON group. T-AOC in the HC group was also significantly higher (P < 0.05) than in the CON group. MDA levels in the HC group were significantly lower (P < 0.05) than in both the LC and CON groups (P < 0.05). The TP content in the HC group was significantly higher (P < 0.05) than in the CON group. IgA levels in both the LC and HC groups were significantly higher (P < 0.05) than in the CON group. The levels of IL-6 and IL-8 in the HC group were significantly lower (P < 0.05) than in the LC and CON groups.Interestingly, the IL-10 level in the HC group was significantly higher (P < 0.05) than in the LC and CON groups. The TNF-α level in the HC group was significantly lower (P < 0.05) than in the CON group. The HCE had no significant (P > 0.05) effect on rumen pH, NH3-N, and VFAs.
