碩士 === 中興大學 === 動物科學系所 === 95 === Moringa oleifera is a historical food plant in India and Africa. It’s rich in nutrient elements including potassium, calcium, iron, proteins and vitamins, and also used as herbal medicines. It is reported to have various biological activities, including antitumor, antiinflammatory, antioxidant, antibacterial, antihypertensive, cholesterol lowering and hepatoprotective. The purpose of this study was to evaluate the effects of diet supplemented with Moringa oleifera on growth performances, blood characteristics and immune response in broilers. Antimicrobial activities of Moringa oleifera before and after simulated digestion to the S. aureus. by in vitro were determinted. The results showed that Moringa oleifera possessed the ability to surpress S. aureus before and after in vitro simulated digestion. On the other hand, the anti-oxidant ablilties of the water and methyl alcohol extractants of Moringa oleifera were measured. The results showed that Water extractants of Moringa oleifera possessed better anti-oxidant ability than methyl alcohol extractants. Furthermore, this study also evaluate the effects of diet supplemented with Moringa oleifera on growth performances, blood characteristics and immune response in broilers in the animal feed experiment. Sixty broilers (Arbor Acres) 21 days of age were randomly allocated to five treatments, and were fed diet supplemented with 0、0.5、1.0、2.0 and 3.0 % Moringa oleifera (powder of leaves). Each treatment had 3 replicates (cages) with 4 birds per replicate (cage). All experimental diets contained 3200 kcal/kg ME and 20 % CP. Birds were housed in wired cages for three-week experimental period, feed and water were supplied ad libitum. Supplying Moringa oleifera had no significantly affected growth performance (p > 0.05) but significantly (p < 0.05) decreased the contents of uric acid, triglyceride and albumin/globumin ratio in the serum of broilers. Moringa oleifera significantly (p < 0.05) increase SRBC antibody titer, γ-globulin content, skin of swelling response, basophils ratio and IgA concentration. Furthermore, Moringa oleifera can significantly decreased E. Coil. count and increase Lactobacillus count in ileum of broilers. However, it had no significantly different effect on antioxidant enzyme in liver and plasma among treatments. It is concluded that supplemention of Moringa oleifera can increase immune ability and improve the microbial population in intestine of broilers. So, it had the potential to use for a feed additive.
