Figure 2: Antioxidant enzymes (MDA, SOD, CAT, and GPx) level in chicken muscles and organs. (a) Total malonaldehyde (MDA); (b) SOD activity; (c) catalase activity; and (d) glutathione peroxidase (GPx) activity of different muscles (breast and thigh) and organs (liver and kidney) of chicken fed with various gradient Moringa oleifera leaves extracts (0.5%, 1.0%, and 1.5% w/w) with nutritional feed/nutritional feed alone were determined. Results are means ± SD of three duplicate measurements. compared to only nutritional feed and compared to other gradient extracts.
