Abstract: This study investigates the effects of varying concentrations of polysaccharide from Atractylodes macrocephala Koidz and microecological preparations on the growth performance and serum hormone levels of weaned piglets. A total of 120 piglets, averaging 7 kg, were randomly assigned to five groups over a 148-day trial, including a control group, an antibiotic group, and three experimental groups with different dietary enhancements. Results indicated that the experimental groups exhibited significantly improved average daily gain and feed-to-meat ratios, particularly in the group receiving both microecological preparations and polysaccharide (p<0.05). Serum analyses revealed increased levels of hormones and proteins, with significant rises in IGF-1, total protein, and globulin content (p<0.05), while triglycerides and cholesterol levels decreased significantly in the combined treatment group (p<0.05). These findings suggest that incorporating polysaccharide from Atractylodes macrocephala and microecological preparations into piglet diets enhances growth performance and positively affects serum biochemical indicators, with the most beneficial effects observed in the combined treatment group.
