Abstract

Introduction Weaned piglets face growth challenges due to low feed intake and weaning stress. Palm oil (PO) rich in long-chain saturated fatty acids may optimize nutrition, but appropriate replacement ratios and mechanisms remain unclear. Methods 144 weaned piglets were randomly assigned to four groups (CON: 4% soybean oil (SO); T1-T3: 25%, 50%, 100% SO replaced by PO) for 35 days. Growth performance, nutrient digestibility, intestinal health, gene expression, and gut microbiota were measured. Results T1 and T3 improved average daily gain (ADG) and reduced feed/gain ratio (0-14 d, p
