摘要： The study evaluated the effects of Pleurotus geesteranus stem (PGS), an agricultural waste rich in bioactive components, on pig growth, antioxidant status, anti-inflammatory responses, short-chain fatty acid (SCFA) production, fecal microbiota, intestinal function, and meat quality across different stages. In Exp. 1, 108 weaned piglets (7.80 +/- 0.41 kg) were randomly assigned to three dietary treatments: control (basal diet), 1.5% PGS, and 3% PGS. In Exp. 2, 108 growing-finishing pigs (76.97 +/- 5.91 kg) were subjected to the same treatments. Results showed that diets supplemented with PGS increased the average daily gain (P < 0.05) and fecal total SCFA contents (P < 0.05) of piglets. PGS supplementation reduced serum interleukin-6 (IL-6) content (P < 0.05) and fecal Escherichia coli counts (P < 0.05) in piglets. The PGS addition could enhance ileal mucosal mucin 1 and mucin 2 expression (P < 0.05), decrease drip loss (P < 0.05), and increase pH45 min value (P < 0.05) of longissimus dorsi muscle (LDM), and downregulate ACC expression (P < 0.05) in LDM of growing-finishing pigs. Overall, PGS supplementation positively influenced growth performance, inflammation control, SCFA production, intestinal health, and meat quality.
