Arrangement of animal experiments. A total of 360 21-day-old Duroc × Yorkshire × landrace weaned piglets (6.59 ± 1.06 kg) were randomly divided into 2 groups with 9 replicates per group and 20 pigs per replicate. The trial lasted 36 days and was divided into two phases; the first phase lasted from days 1–14 and the second phase days 15–36. On the 14th day of the feeding experiment, 18 piglets were selected, including 12 control piglets and 6 treated piglets. Of these, 6 control piglets were injected with normal saline, and the remaining 6 control piglets and 6 treated piglets (AO3 group) were injected with LPS. Blood and tissue samples were collected 4 h after LPS injection.
