Objective: The current experiment was performed to investigate the influence of different dietary levels of Moringa oleifera leaf meal (MOLM) on productive performance, nutrient digestibility, blood parameters, immune response, caecal microbiota, and carcass characteristics of Muscovy ducks (Cairina moschata) during 7 to 63 d of age. Methods: A total of 240 unsexed 7-d-old ducklings were distributed into five (treatment) groups; each one contained six replicates with eight ducklings each. Birds of the first group were fed basal diet without MOLM and served as control, while the other four groups were fed basal diet with 0.25%, 0.50%, 1.0%, and 2.0% MOLM inclusion level, respectively. Results: The obtained results revealed that including MOLM in the diets significantly improved body weight, body weight gain, feed conversion ratio and economic efficiency compared with the control group. Among the different MOLM inclusion treatments, increasing MOLM inclusion level decreased (p<0.05) such previous parameters. Decreasing MOLM inclusion levels in duckling diets increased (p>0.05) the digestibility of organic matter, crude protein, ether extract, and nitrogen free extract, however all MOLM treatments were significantly higher than the control group. Results also revealed that feeding ducks lower MOLM inclusion levels (0.25% or 0.50%) improved blood parameters (p<0.05) compared with the higher inclusion levels (1.0% or 2.0% MOLM) and the control group. Ducks fed different MOLM levels had significantly higher phagocyte index and activity, immunoglobulin G (IgG), IgM, total antioxidant capacity, glutathione peroxidase activity, and superoxide dismutase activity compared with control group. Conclusion: Despite the beneficial effects of all MOLM treatments on growth performance, nutrient digestibility, physiological status, and immune response of duckling, the increasing MOLM inclusion level in the diet had deleterious effects on such studied traits, consequently 0.25% was the best MOLM inclusion level in duckling diets.

The purpose of study is to evaluate in vitro anti-oxidant and anti-inflammatory effects of Moringa Folium and Eucommiae Cortex 2:1 (g/g) mixtures (MEMix). HaCaT and human normal dermal fibroblast were treated with 0.01-1 mg/mL of MEMix to monitor cytotoxicity. Radical scavenging activities of MEMix were examined by DPPH assay. To explore anti-inflammatory effect, Raw 264.7 cells were pretreated with MEMix for 1h and subsequently exposed to LPS for 18h. NO release and cytotoxicity of Raw 264.7 cells were measured by adding Griess and MTT reagents, respectively. TNF-α, IL-1β, IL-6, and PGE2 productions were examined by ELISA. Immunoblot analysis was conducted to examine COX-2 expression in MEMix pretreated Raw 264.7 cells. Up to 1 mg/mL concentration, treatment of MEMix for 24 h did not affect normal dermal fibroblast viability and significantly reduced cell viability of HaCaT cells with no concentration dependency. MEMix increased DPPH radical scavenging activity with concentration dependency. Radical scavenging activities by 1 mg/mL of MEMix was comparable with 30 µM of trolox. Pretreatment of MEMix did not change the reduction of Raw 264.7 cell viability. Exposure of LPS in Raw 264.7 cells significantly increased NO, TNF-α, IL-1β, IL-6, and PGE2 productions, and MEMix pretreatment attenuated these productions by LPS concentration dependently. However, pretreatment with MEMix did not change COX-2 expression by LPS in Raw 264.7 cells. MEMix showed in vitro anti-oxidant and anti-inflammatory activities. MEMix would be useful candidate agent against inflammation.

To investigate the effects of medicinal plants on the shelf life of kakdugi, various kakdugies, added with hot water extract from 62 natural plants, were fermented at 20oC for 15 days. In case of control without the addition, the shelf life required to reach the acidity of 1%(as lactic acid) was 7 days. Morethan two fold extension of shelf life was observed with twenty seven extracts, of which six extracts maintained the hardness of kakdugi higher than that of control over the entire fermentation time. And the number of lactic acid bacteria in above kakdugies was not remarkably different from that of control, and the color(a value) of the liquid of kakdugi, added with Chaenomeles lagenaria, Moringa oleifera, Peaonia lactiflora or Citrus tangerina extract, was similar to that of control. In sensory test, the extracts from the above plants except Moringa oleifera were found to be acceptable. It is suggested that the addition of above three extracts may lead to extension of shelf life of kakdugi, based on the acidity, hardness, color and sensory test.

Twenty crossbred (Yorkshire ${\times}$ Landrace) gestating sows were used to determine the effects of Moringa Oleifera leaf (MOL) supplementation in lactating sow diets with or without banana peel powder (BPP) on reproductive performance, fecal moisture content, rectal temperature and hormone profile. The treatments were as follows: 1) CON (control diet), 2) M1 (control diet + 0.5% MOL), 3) M2 (control diet + 1.0% MOL), 4) M3 (control diet + 0.75% MOL and 0.75% BPP), and 5) M4 (control diet + 1.5% MOL and 1.5% BPP). The diets was fed from da 107 of gestation to weaning. MOL and BPP supplementation decreased (p < 0.05) the fecal moisture content compared with that of the CON at day 0 and 7 after farrowing, and 1.0% supplementation of MOL also decreased (p < 0.05) the fecal moisture content at day 14 after farrowing. On farrowing day, MOL supplementation decreased (p < 0.05) the blood cortisol and norepinephrine concentrations compared with the CON. In conclusion, the results of this study show that MOL supplementation decreased the fecal moisture content and plasma concentrations of cortisol and norepinephrine, and MOL and BPP supplementation also decreased the fecal moisture content in lactating sows.

High soil salinity is the most severe threat to global rice production as it causes a significant decline in rice yield. Here, we investigated the effects of various plant extracts on rice plant stress associated with high salinity. Additionally, we examined various physiological and biochemical parameters such as growth, photosynthetic activity, chlorophyll content, and lipid peroxidation - in rice plants after treatment with selected plant extracts under salt stress conditions. Of the 11 extracts tested, four - soybean leaf, soybean stem, moringa (Moringa oleifera), and Undaria pinnatifida extracts - were found to effectively reduce salt stress. A reduction of only 3-23% in shoot fresh weight was observed in rice plants under salt stress that were treated with these extracts, compared to the 43% reduction observed in plants that were exposed to stress but not given plant extract treatments (control plants). The effectiveness varied with the concentration of the plant extracts. Water content was higher in rice plants treated with the extracts than in the control plants after 6 d of salt stress, but not after 4 d of salt stress. Although photosynthetic efficiency (Fv/Fm), electron transport rate (ETR), and the content of pigments (chlorophyll and carotenoid) varied based on the types and levels of stress and the extracts that the rice plants were treated with, generally, photosynthetic efficiency and pigment content were higher in the treated rice compared to control plants. Reactive oxygen species (ROS), such as superoxide radicals, hydrogen peroxide (H₂O₂), and malondialdehyde (MDA), increased as the duration of stress increased. ROS and MDA levels were lower in the treated rice than in the control plants. Proline and soluble sugar accumulation also increased with the duration of the stress period. However, proline and soluble sugar accumulation were lower in the treated rice than in the control plants. Generally, the values of all the parameters investigated in this study were similar, regardless of the plant extract used to treat the rice plants. Thus, the extracts found to be effective can be used to alleviate the adverse effects of stress on rice crops associated with high-salinity soils.
