Abstract

Almond powder of Irvingia smithii has been incorporated, at the doses of 25 and 50 %, in mice standard ration (prepared by Matadi mill), at INRB, composed of wheat flour, wheat bran and pellets for rabbits to evaluate weight gain, live weight gain and feed conversion and to assess motor activity after 50 days of feeding. Results showed an average increase in live weight gain of 31.08% and 8.36% for the groups of mice fed food supplemented with Irvingia smithii almond powder respectively at 25% and 50% higher than the group of control mice fed exclusively with the standard food. On the other hand, the food consumption index (F.C.I) was very low for the group of mice fed with the food supplemented at 50% (F.C.I. 27.73) and low for the group of mice fed 25% supplemented food (F.C.I. 64.83) compared to the control group (F.I.C. 108,14). In addition, the groups of mice fed the supplemented food did not show motor weakness, even fewer respiratory complications or health problems compared to the control during these 50 days of observation. Live weight gain sufficiently demonstrates the nutritional value of the kernel of I. smithii.

Abstract

The objective of this work is to identify and eliminate antinutritional factors in the fruit kernel of Irvingia smithii (wild mango tree) from the KISANTU botanical garden (DRC) by thermal effect at different temperatures (T1: sun drying, T2: roasting in an oven at 130° C for 30 minutes, T3: boiling for 45 minutes) as a function of time. It appears from the results of our analyzes that the fruit kernels of Irvingia smithii contain antinutritional factors in low proportions: phytates (536.34mg/100g), oxalates (14.84mg/100g), nitrates (12.71mg/100g, 8), and nitrites (50.15mg/100g,). Saponins were not found in these almonds. Treatment of almonds by boiling for 45 minutes (T2 treatment) proved to be the best eliminator of antinutritional factors (60%) followed by treatment of almonds by roasting (T3) (43%), probably by the dissolution of antinutritional factors in medium aqueous (hydrolysis) and their evaporation by boiling which takes place during cooking. Wild mango (Irvingia smithii) levels of antinutrients are low enough to cause poisoning in their consumers; they have not yet been detected in human tissue or the urine of their consumers. We recommend that the roasting of the almond is done before cooking which is done by boiling, a process which will eliminate almost all the antinutritional factors.

Abstract

In Kinshasa, to understand the influence of different proportions of Moringa incorporated into the feeding of chicks, a study was carried out on the COBB 500 chicks. 40 chicks with an average weight of 41 ± 4.71 g for the control and 42 ± 4.06 for the test batch were tested in an experimental system duplicated with foods containing 25% crude protein where diets were supplemented with 5%, 10%, and 15% of the Moringa flour for 21 days. After analysis of the results, we noted the following: It was found that the chicks triplet weight during the experiment in the following order: 152 ± 55.96 g for R1, 181 ± 57, 48 g for R2, 185 ± 46.36 g for R3 and 157.5 ± 27.88 g for feed R0. A non-significant difference (>0.05) was found in the STUDENT t-test, between the body weight gain of chicks fed R0 diet and those fed R1, R2, and R3. SGR (specific growth rate) was significantly correlated with the R3 regimen. Weekly consumption was not constant, and with significant increase during the experimental period. The results of mortality rates obtained during this experiment did not seem to be directly linked to the different regimes but rather to diseases, poor zootechnical construction conditions, and untimely shutdown of electricity in livestock premises. Regarding food Conversion Efficiency (ACE), it is found that diets containing 15% of Moringa show better feed conversion efficiency, with 0% diets showing a decrease in diet as the proportion in Moringa decreases. As regards the quantity of the food consumed, it should be noted that R1 was the most consumed during the experiment.

Abstract

This study was conducted in Gbado-Lite; therefore, it had the objective of producing one-day chickens by palm oil weever combustion. The method adopted for this investigation consisted of constructing an incubator using raffia fibers and using the heat offered by the live combustion of palm oil; the eggs were classified in 3 blocks following the rows on a sieve. This source of energy has achieved a temperature threshold of 37.5 to 39.3 ° C, the recommended temperature for artificial incubation; Hatching rate of 88.9 to 93.5% was recorded, a rate close to the natural incubation. This study has a great socio-economic value because with local inputs, chicks are produced in order to be self-sufficient in meat feed.

The essential oils found in the samples of the three zones showed qualitatively, the following composition: α-pinene, β-pinene, α-phellandrine, Benzene-1-methyl, phellandrene, 3-carene, caryophyllene. While higher alcohols and phytosterols found in the unsaponifiable Kinshasa were the 1-eicosanol, 1-Tétracosanol, 5-α-cholestane, 1-hexacosanol, 1-octacosanol, cholesterol, campesterol, Stigmasterol-1, 1-triacontanol, the β-sitosterol, and stigmastanol.

Abstract

Despite its socio-economic vulnerability, Madagascar has committed itself to carrying out development actions that are reflected in its National Policy. The aim of this study is to produce recommendations for decision-makers on local realities that need to be taken into account regarding the implementation of Sustainable Development Goals. To proceed, four Sustainable Development Goals or SDGs that directly concern cities have been chosen such as: SDG 6 “clean water and sanitation”, SDG 7 “clean and affordable energy”, SDG 11 “sustainable cities and communities” and SDG 12 “responsible consumption and production”. The main methodology is based on an inductive method with a multiscalar approach that starts from the study of the particular case of Ambositra, the locality chosen for this study, to express an opinion on a broader and generalized perspective of Malagasy cities' situations. These results are highlighted: low access to clean water and sanitation, outdated and inadequate public infrastructure and facilities; polluting and non-renewable energy consumption. However, opportunities exist and can be used to achieve these four objectives. Sustainable development is a long-term task which must be included into local development frameworks.

Abstract

Ecological charcoal is coal produced from biodegradable residues rich in carbon, mainly from agricultural residues. This charcoal has been obtained with different operations such as carbonization, molding and compacting to obtain briquettes. To ensure the quality of the coal, several analyses were carried out in the laboratories. The physicochemical characteristics such as moisture content, ash content, fixed carbon content; volatile matter index and lower calorific value are analyzed to better exploit their uses. Its exploitation has many advantages especially in the field of health and environment, especially for the reduction of deforestation and air pollution. This research gives 5 varieties of ecological coal obtained by the valorization of agricultural waste in the region of Vakinankaratra, a region located in the highlands of Madagascar and known for its high potentiality in agriculture and livestock. It is about the valorization of rice straw, rice husk, corn straw, banana peelings, and soybean stalks.

Abstract

For the conservation of the biodiversity of Ranomafana, the valorization of the aromatic and medicinal plants of Ranomafana is an alternative. Two plants of the RUTACEAE family were chosen Vepris ampody and Vepris sp. For this a multidisciplinary approach was adopted: an ethnobotanical survey for the traditional use, ecology of the plant in order to identify environmental conditions favorable to the development of the species, phytochemical screening and identification of the essential oils of the leaves, isolation of mycoendophytes and identification of the fatty acids resulting from the extracts of fermentation. Vepris ampody is used in traditional medicine, and the decoction of leaves and bark is used in case of fever, malaria, fatigue, and muscle pain. The leaves are rich in alkaloids and the essential oils in sabinene. Four strains have been isolated. After fermentation, these four strains produce fatty acids, mostly unsaturated. Vepri ssp. has no medicinal use, it is used to ward off a spell. The leaves are rich in alkaloids. The essential oil is rich in linalool. The perspectives of the study concern the popularization of culture and the identification of alkaloids.
