Competing Role of Bioactive Constituents in Moringa oleifera Extract and Conventional Nutrition Feed on the Performance of Cobb 500 Broilers

Figure 1

In vitro antioxidant activity of MOLE and MOLM extracts. (a) DPPH radical scavenging activity; (b) NO scavenging activity; and (c) total antioxidant capacity of varying gradient Moringa oleifera leaves extracts (MOLE) (0.5%, 1.0%, and 1.5% w/v) and Moringa oleifera leaves meal (MOLM) extracts (0%, 0.5%, 1.0%, and 1.5% w/w) with/without nutritional feed at different concentrations (10–500 μg/mL) were determined spectrophotometrically at 540 nm, 540 nm, and 630 nm respectively. Results are means ± SD of three duplicate measurements. (DPPH: 1,1-diphenyl-2-picryl-hydrazyl free radical; NO: Nitric oxide free radical). In (a) and (b), the control compared to gradient extract with or without nutritional feed is statistically significant (). In (c), compared to only nutritional feed and compared to other gradient extracts.
