A 90-day feeding trial was conducted to evaluate the effects of diets supplemented with three concentrations (control or 0%, 0.5% and 1.0%) of fermented Saccharina japonica and Dendropanax morbifera (FSJ-DM) on the meat composition, growth performance, oxidative stability and fatty acid profile of Korean native black goat (KNBG) meat. The feed conversion ratio and body weight gain (1st to 2nd month) were improved significantly (p < 0.05) in response to feed supplemented with 1.0% FSJ-DM. Moisture content was increased, whereas ether extract and cholesterol contents were decreased in meat obtained from goats supplemented with 1.0% FSJ-DM dietary feeds (p < 0.05). In the same diet group, the total saturated fatty acids (ΣSFA) were lower, whereas the sum of polyunsaturated fatty acids (ΣPUFA) was higher, along with higher PUFA/SFA ratio and lower n-6/n-3 ratio (p < 0.05). On an average, the dietary supplementation of 1.0% FSJ-DM reduced the thiobarbituric acid reactive substance (TBARS) and pH values of goat meat. Overall, the results of this study suggest that diet supplemented with 1.0% FSJ-DM improves the meat composition, growth performance and fatty acid profile and reduces lipid oxidation of goat meat.
