Effect of Eucommia ulmoides Extract on the Immunity of Weaned Piglets
Abstract：To study the effect of different levels of Eucommia ulmoides extract on the immunity of weaned piglets, this experiment selected 60 healthy 30-day-old weaned piglets, randomly divided into 4 groups, with 3 replicates per group and 5 piglets per replicate. The control group was fed a basal diet, while the experimental groups 1, 2, and 3 were fed diets supplemented with 100, 200, and 400 mg/kg of Eucommia ulmoides extract, respectively. The pre-test period lasted 1 week, and the main test period lasted 4 weeks. The results showed that compared to the control group, the level of immunoglobulin A in the serum of piglets in group 2 was significantly increased (P < 0.05). The levels of immunoglobulin G and interleukin-10 in the serum of all three experimental groups were significantly increased (P < 0.05). The levels of tumor necrosis factor-α in piglets from groups 2 and 3 were significantly reduced (P < 0.05). The results indicate that adding 200 mg/kg of Eucommia ulmoides extract to the diet can significantly enhance the immunity of weaned piglets.
