The encapsulation efficiencies for BVDV and AHP were 66.8% and 73.2%, respectively. AHPPE demonstrated recruitment of antigen-presenting cells at the injection site and activated IgA cells in the duodenum, jejunum, and ileum, inducing to increased IgA expression across multiple intestinal segments. Furthermore, AHPPE significantly induced serum IgG production and elevated levels of cytokines, including IL-4, IL-10, IL-17, IFN-\u03b3, and TNF-\u03b1 (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt;0.05).
