Abstract
We investigated the beneficial effects of Ecklonia cava by-product (ECB), a residual product obtained after polyphenol extraction from Ecklonia cava, on normal rats. Male Sprague-Dawley rats were divided into the following three groups: Control group (NC), received basal diet; ECB 0.1 group, received basal diet supplemented with 0.1% ECB for 21 days; ECB 0.5 group, received basal diet supplemented with 0.5% ECB for 21 days. The productivity, serum immunoglobulin level, expression levels of muscle-related genes, and cecal microflora were measured in all the treatment groups to evaluate the potential use of ECB as a feed additive. The ECB 0.1 group exhibited enhanced expression of Myod, Myog, and Igf1 genes, which increased the body weight of rats. Additionally, treatment with ECB increased the cecal Lactobacillus spp. counts and the serum immunoglobulin G levels in rats. Thus, ECB can effectively increase body weight and can be a potential feed additive for improving growth.
