Ferulic acid: A natural compound as an efficient feed additive for GIFT (Oreochromis niloticus)

This study aimed to investigate the effect of dietary ferulic acid (FA) supplementation on growth performance, antioxidant capacity and some physical characteristics of flesh in genetic improvement of farmed tilapia (GIFT) juveniles. Five diets supplemented with 0, 50, 100, 200 and 400 mg/kg FA were...

Summary:This study aimed to investigate the effect of dietary ferulic acid (FA) supplementation on growth performance, antioxidant capacity and some physical characteristics of flesh in genetic improvement of farmed tilapia (GIFT) juveniles. Five diets supplemented with 0, 50, 100, 200 and 400 mg/kg FA were prepared. Weight gain was significantly increased, while feed conversion ratio, viscerosomatic index and hepatosomatic index were significantly decreased in fish fed FA diet at 100 mg/kg feed (p < .05). FA supplementation improved hepatic and serum superoxide dismutase and catalase activities, but decreased the malondialdehyde content (p < .05). Furthermore, with the addition of FA, serum triacylglycerol, cholesterol, low‐density lipoprotein cholesterol contents, alanine aminotransferase and aspartate transaminase activities were reduced, whereas serum high‐density lipoprotein cholesterol content, alkaline phosphatase and lysozyme activities were enhanced. The texture profile analysis parameters and water‐holding capacity tended to increase while cooking loss was decreased by dietary FA supplementation (p < .05). These results suggested that dietary FA supplementation increased the growth performance and antioxidant capacity of GIFT, and improved some physical characteristics of flesh and serum biochemical parameters. The optimum dietary FA level was 100 mg/kg in diet.
