A total of fifteen yearling indigenous short-eared Somali goat breeds with an initial weight of 15.2 ± 0.30 kg were assigned to three treatment groups using completely randomized design. Pigeon pea (Pp) and Moringa stenopetala (MS) feeds were formulated using 0%, 5%, and 10% inclusion levels of MSLM and PPLM as experimental diets, respectively. The feed of the experiment was prepared in two levels (2 kg of Moringa stenopetala and 2 kg of pigeon pea) and was supplemented to experimental animals in treatments one and two, respectively. The average e initial body weight of selected male goats was 18.82 ± 0.37, 18.8 ± 0.37 and 17.8 ± 0.37 kg under treatment groups T1, T2 and control respectively. Data was analyzed using general linear model (GLM) procedure of SAS computer package Version 9.0 (SAS, 2002). The final weights gain (FWG) of goats on T1 and T2 of experimental group was significantly (P 0.05) the final weight gain of goat supplemented on Moringa stenopetala (T1) and pigeon pea levels (T2). The mean average weight gains (AWG) obtained from the supplemented group in this study were 7.50 ± 0.37 and 7.82 ± 0.37 kg for T1 and T2, whereas mean weight gains for un-supplemented goats were found to be 6.26 ± 0.37 kg. Feeding of dried Moringa stenopetala and pigeon pea leaves mixture improved body weights and average daily body weight gain without affecting feed intake and overall health of Somali goat breed. As Moringa stenopetala and pigeon pea leaves are rich nitrogen/protein source, they can be used effectively as substitute for conventional concentrate in the diet of growing goats at small holder farmer’s level where they can be grown in abundance. Therefore, for higher quality of forage and higher total DM yield for animal feeding, moringa should be harvested at wider harvesting intervals of at least 6th- to 8th-week intervals. Similarly, for pigeon peas, 4- to 6-week harvesting interval can result in optimum forage as well as feed quality and resulted in better growth performances for Somali short-eared goat breeds.展开更多

Their valuation is therefore a major issue for sustainable development. The main objective of this study aims to develop an organic fertilizer derived from moringa leaves and cocoa pod husks that can improve soil quality and plant growth. The experimental design consisted of completely randomized blocks in three repetitions. The experiment was carried out in five treatments: T0: no fertilization, T1: 100% cocoa pods, T2: 75% cocoa pods + 25% Moringa leaves;T3: 50% cocoa pods + 50% Moringa leaves;T4: 25% cocoa pods + 75% Moringa leaves;T5: 100% Moringa leaves. Three doses were applied: 1;2;4 kg/m2. The trial took place over three growing cycles. The results of the soil analysis compared to the control revealed a significant improvement in physicochemical parameters. Variation of pH from (6.1 to 7.2), calcium from (1.4 to 4.13), magnesium from (0.450 to 0.870), potassium from (0.096 to 0.365) cmol+/kg. Carbon and nitrogen were recorded (1.02% to 2.77%) and (0.12% to 2.56%) respectively. The CEC (cation exchange capacity) saw a clear improvement (4.2 to 9.03) cmol+/kg. Concerning the growth parameters, the control plants recorded an average height of (31.19 cm) while those that benefited from the treatments oscillated between (55.51 to 105.57 cm). In terms of production, the best yields are attributed to treatments T3 and T4 with (37.66 t/ha) and (51.176 t/ha) respectively. The T3 and T4 formulations could help improve the fertility of agricultural soils and the yield of market garden products such as eggplant.展开更多

The study detected the level of tumor necrosis factor (TNF-α) to monitor the immune and inflammatory responses of experimentally infected mice. Through meat inspection, a total number of 2125 male bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were examined under the authority of Albsatine and Alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from March 2022 to April 2023. The overall prevalence of the disease among bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and M. oleifera extracts showed cysticidal activity in experimentally infected mice. A decrease in the numbers of cysticerci was found in all treated mice groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group;higher than that was recorded in both M. oleifera (72.23%) and albendazole-treated ones (80.56%). Postmortem findings proved that M. oleifera and B. aegyptiaca reduced cysticerci numbers comparable to a commercial anthelmintic. The study showed a significant decrease (P 0.001) in TNF-α levels after treatment with Balanites and Moringa extracts, compared with the untreated control and the albendazole-treated groups.展开更多

Some studies have estimated that paracetamol is involved in 56% of acute liver diseases, whereas 0.4% of paracetamol overdose cases result in fatal-ity. In this study, the effects of Moringa oleifera on paracetamol toxicity in the liver were explored. It has been demonstrated that Moringa oleifera is highly nu-tritious, contains bioactive molecules, and is therapeutically beneficial. Many studies have shown that Moringa oleifera leaves possess a wide range of biologi-cal properties, including antioxidant, tissue protection, analgesic, antihyperten-sive, and immunomodulatory activities. This study highlights the protective role of Moringa oleifera on handling possible paracetamol hepatotoxicity in male rats. .展开更多

The causative agents of common bacterial infections that are thought to cause water-borne diseases, namely, Escherichia coli, Enterococcus faecalis, and Bacillus cereus were chosen for the study. The paper-disc diffusion method was used with treatments arranged in a completely randomized design and replicated four times. The M. oleifera extracts showed more inhibitory effect than those of M. ovolifolia. The conventional antibiotic Ampicilin generally showed higher inhibitory effect than the extracts of both M. oleifera and M. ovalifolia. The inhibitory effect varied depending on the solvent used. The n-hexane extracts of both seeds and bark of M. ovalifolia and M. oleifera had almost the same inhibition activities (6 ± 1 mm mean inhibition zones) on B. cereus, E. coli and E. faecalis. The n-hexane extract generally gave lower antibacterial activities than those of the other solvents for seeds and back. The results of the study showed that M. oleifera and M. ovalifolia had a degree of antibacterial properties against the selected test organisms that cause water borne diseases.展开更多

文摘This study was conducted at Fafan Research Center, Golajo research site to evaluate the effect of Moringa stenopetala and pigeon pea leaf supplementation on growth performance of short-eared Somali goat breed. A total of fifteen yearling indigenous short-eared Somali goat breeds with an initial weight of 15.2 ± 0.30 kg were assigned to three treatment groups using completely randomized design. Pigeon pea (Pp) and Moringa stenopetala (MS) feeds were formulated using 0%, 5%, and 10% inclusion levels of MSLM and PPLM as experimental diets, respectively. The feed of the experiment was prepared in two levels (2 kg of Moringa stenopetala and 2 kg of pigeon pea) and was supplemented to experimental animals in treatments one and two, respectively. The average e initial body weight of selected male goats was 18.82 ± 0.37, 18.8 ± 0.37 and 17.8 ± 0.37 kg under treatment groups T1, T2 and control respectively. Data was analyzed using general linear model (GLM) procedure of SAS computer package Version 9.0 (SAS, 2002). The final weights gain (FWG) of goats on T1 and T2 of experimental group was significantly (P 0.05) the final weight gain of goat supplemented on Moringa stenopetala (T1) and pigeon pea levels (T2). The mean average weight gains (AWG) obtained from the supplemented group in this study were 7.50 ± 0.37 and 7.82 ± 0.37 kg for T1 and T2, whereas mean weight gains for un-supplemented goats were found to be 6.26 ± 0.37 kg. Feeding of dried Moringa stenopetala and pigeon pea leaves mixture improved body weights and average daily body weight gain without affecting feed intake and overall health of Somali goat breed. As Moringa stenopetala and pigeon pea leaves are rich nitrogen/protein source, they can be used effectively as substitute for conventional concentrate in the diet of growing goats at small holder farmer’s level where they can be grown in abundance. Therefore, for higher quality of forage and higher total DM yield for animal feeding, moringa should be harvested at wider harvesting intervals of at least 6th- to 8th-week intervals. Similarly, for pigeon peas, 4- to 6-week harvesting interval can result in optimum forage as well as feed quality and resulted in better growth performances for Somali short-eared goat breeds.
文摘Organic fertilizers generally come from agricultural co-products. Their valuation is therefore a major issue for sustainable development. The main objective of this study aims to develop an organic fertilizer derived from moringa leaves and cocoa pod husks that can improve soil quality and plant growth. The experimental design consisted of completely randomized blocks in three repetitions. The experiment was carried out in five treatments: T0: no fertilization, T1: 100% cocoa pods, T2: 75% cocoa pods + 25% Moringa leaves;T3: 50% cocoa pods + 50% Moringa leaves;T4: 25% cocoa pods + 75% Moringa leaves;T5: 100% Moringa leaves. Three doses were applied: 1;2;4 kg/m2. The trial took place over three growing cycles. The results of the soil analysis compared to the control revealed a significant improvement in physicochemical parameters. Variation of pH from (6.1 to 7.2), calcium from (1.4 to 4.13), magnesium from (0.450 to 0.870), potassium from (0.096 to 0.365) cmol+/kg. Carbon and nitrogen were recorded (1.02% to 2.77%) and (0.12% to 2.56%) respectively. The CEC (cation exchange capacity) saw a clear improvement (4.2 to 9.03) cmol+/kg. Concerning the growth parameters, the control plants recorded an average height of (31.19 cm) while those that benefited from the treatments oscillated between (55.51 to 105.57 cm).

文摘Obesity has brought great challenges to global human health,and how to effectively prevent and control the occurrence and development of obesity has become an urgent problem.The role and mechanism of 4-[(α-Lrhamnosyloxy)benzyl]isothiocyanate(MITC),an active ingredient of Moringa oleifera Lam.,in the regulation of lipid metabolism have not been comprehensively investigated.In the present study,we investigated the mechanism of MITC in inhibiting lipid accumulation in mice fed with a high-fat diet(HFD)in terms of both lipolysis and central appetite regulation mediated by the gut microbe-gut-brain axis.MITC enhanced the characteristic indices associated with HFD mice and also promoted adipocytolysis and brown fat thermogenesis.Moreover,MITC was observed to improve leptin resistance,modulate the composition of gut microbiota such as Ruminococcaceae,Parasutterella,and Acetatifactor,promote 5-hydroxytryptamine secretion,further enhance the secretion of glucagon-like peptide-1(GLP-1)and peptide tyrosine-tyrosine(PYY)to activate peroxisome proliferator-activated receptor(PPAR)signaling in the hypothalamus,and modulate feeding behavior to inhibit lipid accumulation in HFD mice.These data suggest that MITC supplementation can help to alleviate obesity or obesity-related diseases.
文摘Moringa oleifera have laxative effects,but their active compositions and mechanisms are not very clear thus far.To this end,we systematically explored the active components and mechanism of M.oleifera leaves in relieving constipation by using the slow transit constipation(STC)mouse model and network pharmacology.The results of animal experiments showed that M.oleifera aqueous extract(MOA)had good laxative activity,and its 70%alcohol soluble part(ASP)also showed significant laxative activity(P<0.01).Network pharmacological prediction results suggested that L-phenylalanine(Phe)was the key compound of ASP,and it might relieve constipation through tachykinin receptor 1(TACR1)and three kinds of adrenergic receptors,includingα_(1A)(ADRA1A),α_(2A)(ADRA2A),andα_(2B)(ADRA2B).Further animal experiment results showed that Phe significantly promoted gastrointestinal motility.Phe may relieve STC by enhancing the release of substance P(SP)and upregulating the m RNA expression of TACR1 in the ileum.Importantly,Phe may also promote intestinal movement by downregulating the m RNA expression of ADRA2A and ADRA2B and upregulating the m RNA expression of Calm and the m RNA and protein expression of myosin light chain 9 in the ileum,thereby activating the G protein-coupled receptor-myosin light chain signaling pathway.These results lay a foundation for the application of M.oleifera and Phe in constipation.

文摘The extensive use of polymeric materials in single-use packaging has driven the need to develop biodegradable alternatives.This study investigates the incorporation of graphene oxide(GO)and Moringa oleifera seed oil(MOSO)into a gelatin matrix to create polymer films and evaluate their potential as active packaging materials.The properties of these films were evaluated using structural,thermal,mechanical,optical,and physicochemical methods to determine their suitability for food packaging applications.The results showed that GO and MOSO were homogeneously dispersed in the gelatin matrix,forming colloidal particles(around 5μm in diameter).The addition of GO increased opacity by approximately 20 times the base value while MOSO affected light transmittance without impacting opacity.Mechanical properties were affected differently,GO acted as a crosslinking agent reducing elongation and increasing tensile strength at break,on the other hand MOSO acted as a plasticizer,making films more plastic increasing elongation a 30%.These effects counteracted each other,and similar behavior was recorded in differential scanning calorimetry.The films exhibited an improved water vapor resistance,which is crucial for food packaging.These findings indicate that the incorporation of GO and MOSO into a gelatin matrix may produce biodegradable polymer films with enhanced properties,suitable for active packaging in the food industry.
文摘Objective:To investigate the effect of Moringa oleifera leaf extract on semen quality parameters in Teressa goat buck.Methods:A total of 25 semen samples from six bucks were selected for the study.Spermatozoa of 150×10^(6) were incubated in 0,300,500 and 700μg of leaf extract as groupⅠ,Ⅱ,Ⅲ and Ⅳ,respectively.Liquid stored semen samples were analysed for motility,viability,total sperm abnormalities,plasma membrane,acrosomal and nuclear integrities,seminal plasma intracellular enzymes[aspartate aminotransferase(AST),alanine aminotransferase(ALT)and lactate dehydrogenase(LDH)]and total antioxidant capacity(TAC)and spermatozoa malondialdehyde(MDA)and cholesterol efflux in comparison with the control group(groupⅠ)for up to 72 h.Results:Moringa oleifera leaf extract(500μg/150×10^(6) spermatozoa)-treated semen had significantly higher motility,viability,plasma membrane,acrosomal and nuclear integrities,and TAC(P<0.05),and had significantly lower total sperm abnormalities,AST,ALT,LDH,MDA production and cholesterol efflux compared to those in other Moringa oleifera leaf extract treated(300 or 700μg/150×10^(6) spermatozoa)and control groups at different hours of liquid storage(P<0.05).Semen quality parameters and TAC showed an increasing trend and total sperm abnormalities,MDA production,leakage of intra-cellular enzymes and cholesterol efflux showed a decreasing trend from group Ⅰto group Ⅲand then an opposite trend from group Ⅲ to group Ⅳ at different hours of liquid storage.Conclusions:Moringa oleifera leaf extract 500μg/150×10^(6) spermatozoa can be used for liquid semen preservation in Teressa goat at Andaman and Nicobar Islands.

文摘The aim of the present study was to determine the prevalence of bovine cysticercosis in both cattle and buffloas, in Egypt and to assess the cysticidal efficacy of Balanites aegyptiaca fruits (B. aegyptiaca) and Moringa oleifera seeds (M. oleifera) extracts in experimentally infected mice. The study detected the level of tumor necrosis factor (TNF-α) to monitor the immune and inflammatory responses of experimentally infected mice. Through meat inspection, a total number of 2125 male bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were examined under the authority of Albsatine and Alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from March 2022 to April 2023. The overall prevalence of the disease among bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and M. oleifera extracts showed cysticidal activity in experimentally infected mice. A decrease in the numbers of cysticerci was found in all treated mice groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group;higher than that was recorded in both M. oleifera (72.23%) and albendazole-treated ones (80.56%). Postmortem findings proved that M. oleifera and B. aegyptiaca reduced cysticerci numbers comparable to a commercial anthelmintic. The study showed a significant decrease (P 0.001) in TNF-α levels after treatment with Balanites and Moringa extracts, compared with the untreated control and the albendazole-treated groups.
文摘In recent years, there has been an increase in concern regarding the effects of paracetamol poisoning on liver tissues, particularly when consumed in large amounts. Some studies have estimated that paracetamol is involved in 56% of acute liver diseases, whereas 0.4% of paracetamol overdose cases result in fatal-ity. In this study, the effects of Moringa oleifera on paracetamol toxicity in the liver were explored. It has been demonstrated that Moringa oleifera is highly nu-tritious, contains bioactive molecules, and is therapeutically beneficial. Many studies have shown that Moringa oleifera leaves possess a wide range of biologi-cal properties, including antioxidant, tissue protection, analgesic, antihyperten-sive, and immunomodulatory activities. This study highlights the protective role of Moringa oleifera on handling possible paracetamol hepatotoxicity in male rats. .

文摘Antibacterial activity of methanol, n-hexane and water extracts of seeds and bark of Moringa oleifera and Moringa ovalifolia was conducted. The causative agents of common bacterial infections that are thought to cause water-borne diseases, namely, Escherichia coli, Enterococcus faecalis, and Bacillus cereus were chosen for the study. The paper-disc diffusion method was used with treatments arranged in a completely randomized design and replicated four times. The M. oleifera extracts showed more inhibitory effect than those of M. ovolifolia. The conventional antibiotic Ampicilin generally showed higher inhibitory effect than the extracts of both M. oleifera and M. ovalifolia. The inhibitory effect varied depending on the solvent used. The n-hexane extracts of both seeds and bark of M. ovalifolia and M. oleifera had almost the same inhibition activities (6 ± 1 mm mean inhibition zones) on B. cereus, E. coli and E. faecalis. The n-hexane extract generally gave lower antibacterial activities than those of the other solvents for seeds and back. The results of the study showed that M. oleifera and M. ovalifolia had a degree of antibacterial properties against the selected test organisms that cause water borne diseases.
