Dietary hydrolysable tannin improves intestinal health of largemouth bass (Micropterus salmoides): insights from NF-κB signaling pathway and arachidonic acid metabolism.

ABSTRACT:

Background

To more effectively address the scarcity resources and elevated costs associated with fishmeal (FM), the utilization of cottonseed protein concentrate (CPC) as an alternative in aquaculture feeds has become increasingly prevalent. However, high levels of CPC substitution for FM have been reported to suppress the growth of fish and impair intestinal health. Hydrolysable tannin (HT) has been reported to exhibit biological activities such as anti-inflammatory and antioxidant activities, but whether the HT can generate positive biological effects on the intestinal health of largemouth bass (Micropterus salmoides) remains unknown. Largemouth bass (initial weight: 6.03 ± 0.01 g) were subjected to an 8-week feeding trial with three different diets: a basic diet (named as the NC
