Effects of dietary supplementation with grape seed powders on growth performance and muscle nutrition of grass carp (<i>Ctenopharyngodon idella</i>) by gut microbiota mediation.

ABSTRACT:

Objective

To investigate whether grape seed powders (GSP) contribute to growth-promoting in aquaculture, a comprehensive analysis of the effects of GSP on grass carp (Ctenopharyngodon idella) was performed.

Methods

Six hundred grass carp were divided into four groups, including the control and the low (100 mg/kg), middle (500 mg/kg), and high (1000 mg/kg) GSP-supplemented groups. The material composition, growth parameters, physiological/biochemical indexes, and muscle nutrition were analyzed.

Results

After feeding of 60 days, the weight gain rate, specific growth rate, and condition factor of grass carp significantly increased with GSP supplementation at low and middle levels in comparison to the blank control (P < 0.05). Additionally, the catalase acti
