Carotenoid and anthocyanin levels in skin, fin, and muscle increased with higher MRE levels. Histologically, MRE\u20103 improved intestinal villus height, whereas MRE\u20104 induced more pronounced hepatic hyaline degeneration. In conclusion, dietary inclusion of 3% MRE was identified as the optimal level for fancy carp, improving growth, feed efficiency, immune and antioxidant responses, pigmentation, and intestinal development without adverse hepatic effects.\n                  <\/jats:p>","DOI":"10.1155\/anu\/8985910","type":"journal-article","created":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T03:46:39Z","timestamp":1782791199000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dietary Microencapsulated Roselle (\n                    <i>Hibiscus sabdariffa<\/i>\n                    L.)
