Abstract

A study was conducted at Gbado-Lite city to assess the capacity of plantain macro-propagation by applying the PIF technique. To do this, the fragments of three types of banana trees: French, true horn and false horn were sown in a propagator containing sawdust. After germination, the seedlings were transplanted into polyethylene bags containing a mixture of clay and potting soil and installed under the shadehouse. With regard to the results obtained and statistical tests (at the 5% threshold), the significant difference between these three types of banana trees was only observed for the number of seedlings emitted by explant, the number of suckers weaned, the height of the plants at weaning and the mortality rate of plants in the nursery. Thus, emergence having taken place 2 weeks after sowing, after 46 days after resumption and 61 days after sowing, the French type was significantly different from two others with an average of 6 seedlings emitted and 4 suckers weaned per explant; the true and false horn being tied with 5 seedlings and 3 weaned suckers per explant. As for the height of the plants at weaning, the true horn (19.9 cm) was significantly higher than the other two (French: 17.7 cm and false horn: 19.6 cm). Finally, with 1.1% for True horn had a significantly lower mortality rate for plants in the nursery than the others (6.7% for French horn and 3.8 % for False horn). Although, the PIF technique influenced the suckering in a way strongly dependent on the cultivars, it can be popularized for these three types studied in order to promote banana cultivation in the agro-ecological conditions of Gbado-Lite.

Abstract

The poultry industry plays a crucial role in meeting the global demand for animal protein. To ensure optimal growth and productivity of poultry, the formulation and processing of high-quality feed are essential. Feed pelleting is a common method employed to enhance the nutritional value, digestibility, and handling characteristics of poultry feed. The machine which meant for the production of poultry feed pellets in good quantities, was designed, fabricated and its performance evaluation was carried out accordingly. The independent dual operated Poultry Feed Pelleting Machine permits constant production line since the prime mover (diesel engine) would be plunged into operation as at when due, that is, when electricity power supply failed. The materials used were locally sourced which included; mild steel, high carbon steel, aluminum, 3hp electric motor, prime mover and axle. The base materials are corn, soybean, wheat, rice bran, wheat bran, herbs, fish meal, groundnut cake etc. The machine functioned reliably at the throughput capacity of 95kg per hour and up to 800kg per day with 95% efficiency proved its high performing rate. Moreover, the study showed that useful information in designing pelleting machine that produced pellet optimally when the appropriate moisture condition for feed materials is considered ranging from 20% - 30% with temperature range of 500C-700C. The results indicate that the developed machine offers significant advantages in terms of pellet quality, production efficiency, and energy consumption compared to conventional pelleting methods. The developed machine is recommended to facilitate the production of poultry feed pellets for small scale and medium scale farmers.

Abstract

The Malagasy population generally consumes rice with "laoka" as a side dish. A diet that has become an atypical practice, a lifestyle well structured around the very common foods for typical Malagasy dishes. A nutritional analysis enabled us to determine their nutritional composition, and thus the energy intake that these foods can contribute to the proper functioning of the human metabolism for good health. A survey to assess the weekly consumption frequency of leafy vegetables by Tananarivians was carried out in 1,280 households. The constituent elements were then determined using TXRF for each elemental constituent of the solid samples. The macronutrient contents obtained from the analyses of these samples were used to determine overall energy values. Analysis of the extracts showed that most of them contained flavonoids and phenolic compounds respectively. Based on these results, Anatsinahy (Bidens pilosa) was found to be the most lipid-rich of the other brede species. Anamamy (Solanum nigrum) (38.88%) and Anandrano (Nasturtium officinale) (34.28%) are recommended for their high protein content. The carbohydrate content, ranging from 20.85% for Bidens pilosa to 52.69% for leaves of Ypomeas Batatas, could contribute to the nutrition, food security, and health of resource-poor people. The presence of these secondary metabolites in leafy vegetables may explain the particular pharmacological virtues of some of them, such as the alterative, antifungal, anti-inflammatory, antirheumatic, and styptic properties of Bidens pilosa, and the anesthetic, diuretic, digestive, sialagogue, antiasthmatic and antiscorbutic properties of Spilanthes acmella Murr. The presence of tannins, alkaloids, saponins, and flavonoids reported in this study may induce antidiarrheal activity.

Abstract

The study delves into the critical topic of dietary habits and alcohol consumption patterns among the elderly in Ugheli, Delta State, Nigeria. This investigation aims to shed light on the health implications of low vegetable consumption and local gin intake within this aging population. The research addresses the pressing issue of the health and well-being of the elderly in Ugheli, Delta State. Specifically, it focuses on two critical problems: low vegetable consumption and excessive local gin consumption. These issues are of concern due to their potential adverse effects on the health of older adults. Local gin consumption may stem from cultural practices and limited understanding of its health risks. To address these problems, a survey research approach was employed. The sample size included 375 retirees from various communities within Ugheli. This sample size was determined using a stratified non-proportional sampling method. The research findings revealed that low vegetable consumption was associated with health risks such as weight gain, digestive problems, goiter, increased cancer risk, and various chronic conditions. Local gin consumption among the elderly was linked to poor coordination, central nervous system depression, excessive appetite, excessive urination, and low blood glucose levels. This research carries significant implications for the elderly population in Ugheli, Delta State. By highlighting the health risks associated with low vegetable consumption and excessive local gin intake, it underscores the need for tailored interventions, education programs, improved access to fresh produce, and cultural sensitivity in healthcare approaches. Ultimately, this study aims to improve the overall health and quality of life of older adults in the region.

Abstract

In this paper, a SEIR epidemic model is considered; where individuals in the population are assigned to different compartments of SEIR defined with respect to epidemic status of Covid-19 in Nigeria. The article has demonstrated a simple mathematical model for the transmission of Covid-19 disease taking into account loss of human immunity with the aim that this model proves useful in controlling the possibility of a person contracting Covid-19 twice. When the basic reproduction number means that the Covid-19 free equilibrium solution is locally asymptotically stable. This suggests that the number of new cases of the disease will decrease over time and eventually will vanish as that whcih causes are established. The basic reproduction number and the model analysis (local stability of disease-free equilibrium and disease-endemic equilibrium) of the system were calculated and the stability of the SEIR model was checked.

Abstract

This study delves into the critical realm of the health implications of meal skipping among the elderly and delineates strategies for the enhancement of healthy food consumption within the unique context of Ugheli, Delta State. As the elderly populace plays an indispensable role in shaping the social, cultural, and familial tapestry of any community, understanding the dietary habits and their impacts on health becomes paramount. The research design comprises both experimental and survey methods, integrating dietary experiments with comprehensive questionnaires. Ugheli, a culturally diverse city in Delta State, Nigeria, forms the geographical scope of this study. The population encompasses 19,235 pensioners, representing a significant segment of the community. Three hundred and sixty-eight respondents, including retirees and health professionals, participated in the study, yielding a response rate of 98%. The findings highlight a pressing concern: a substantial proportion of the elderly in Ugheli grapples with undernutrition, particularly among females. Moreover, meal skipping among the elderly yields a host of adverse health effects, including metabolic disruptions, weight gain, elevated blood pressure, and impaired cognitive function. To mitigate these issues, the study posits evidence-based strategies for bolstering healthy food consumption. These strategies encompass discouraging meal skipping, promoting whole-grain intake, encouraging food fortification, and reducing excessive carbohydrate consumption. Notably, consensus prevails among both male and female respondents and health professionals regarding the significance of these strategies. The implications extend to public health policies and community development in Ugheli, Delta State.

Abstract

The overall aim of this study was to evaluate the reproductive performance of Oreochromis niloticus reared in ponds fed with periphyton and rice bran. It was carried out using a database resulting from an experiment carried out in the Gemena town hall, South Ubangi province in the Democratic Republic of Congo with Oreochromis niloticus fry fed on periphyton and rice bran. The methodological approach consisted of sampling the physico-chemical parameters of the pond water and the reproductive parameters, in particular the gonado-somatic ratio (GSR), the condition factor (K), fecundity and oocyte size. After analysis by pond category, it was found that the two treatments differed in terms of gonado-somatic ratio and condition factor. Treatment T1 is characterised by a relatively better value (RGS varying from 0.35 to 5.03 and K varying from 0.47 to 6.75) than treatment T0 (RGS varying from 0.34 to 3.91 and K varying from 0.20 to 3.26). The absolute fecundity of Oreochromis niloticus in the ponds with rice bran and those with periphyton varied respectively from 216-1504 and 279-1570. In contrast, the relative fecundity was 3.17-15.7 for the ponds with rice bran and 5.49-17.2 for the ponds with periphyton. These values correspond to total lengths of 11.6-18.1 Cm and 14.6-22.2 Cm, respectively. Oocyte diameter ranged from 0.95-2.00 mm, with an average of 1.63±0.05 mm, and from 0.89-2.15 mm, with an average of 1.59±0.05 mm, for females from ponds with rice bran and those with periphyton, respectively. At the end of this study, the results obtained showed that the females fed with periphyton showed a higher relative fecundity than those fed with rice bran. The data collected on the reproductive parameters indicate better reproductive performance in ponds fed with periphyton than in ponds fed with rice bran.

Abstract

On March 10, 2020, the Democratic Republic of the Congo (DRC) declared the onset of the COVID-19 pandemic. Since then, there have been a total of 95,738 cases, comprising 95,736 confirmed cases and 2 probable cases, with 84,321 recoveries and 1,464 fatalities. Following the guidance of the World Health Organization (WHO), African nations have been actively working to establish and expand vaccination programs. Starting the vaccination campaign in the DRC on April 19, 2021, a total of 10,893,593 individuals, estimated to be 20.18% of the target population, have received vaccines. Among them, 882,106 individuals, or 1.65%, have received their first dose, while 8,576,320 individuals or 15.89% of the target population, and have been fully vaccinated. The Democratic Republic of the Congo aims to vaccinate 53.9 million people against COVID-19, according to the technical response secretariat. This article focuses on the post-vaccination symptoms observed in a resident of the Wapinda sector, Yakoma territory in Nord-Ubangi Province, which has raised curiosity and serves as the subject of discussion.

Abstract

Beet (Beta vulgaris L.) is a vegetable, but its sweet taste prompted us to explore its use in wine-making. After TXRF analysis and phytochemical screening, the richness in micronutrients and chemical families of its pulp and peel led to the use of whole beet in the winemaking process. The temperature observed in each trial is well within the temperature range for red winemaking (22.0°C- 28.8°C). the pH decreases as a function of fermentation time, due to ethanol production and the consumption of part of the malic acid by the yeasts. The pH of musts and wines is generally between 3 and 4. The conversion of sugar is not total for all the trials but we can say that the fermentation is accelerating. There is still a small sugar-to-alcohol conversion scale equal to 0.2%. During the fermentation, the alcoholic strength depends on the type of hydrolysis used and the rate of glucose release. The values of the total acidity in H2SO4 were found to range from 3.867 to 4.586. According to the results of the analyses carried out, the physico-chemical characteristics of the beet wine comply with European regulations. The vinasse was recycled and underwent a composting process. The C/N ratio (15.16), P (0.95%), Ca (3.05%), Mg (2.25%), K (5.16%) and Na (0.24%) contents were determined. The vinasse compost was used to prepare a beet nursery, and then allowed the young plants from the nursery to grow normally. Beet farming in a zero-waste circular economy.
