The objective of this work is to analyze the biochemical parameters of Zingiber officinale (ginger) and Curcuma Longa (turmeric) found in the locality of Daloa. The samples were purchased in the markets of Daloa. The dry matter, ash and lipid contents were determined by the AOAC (Association of Official Analytical Chemists) method. Those of proteins, total sugars, reducing sugars were carried out respectively by the methods of Kjeldahl, Bernfeld and Dubois. A phytochemical study was done by Evans method. The contents of total flavonoids and total polyphenols were determined respectively according to the methods of Wood and Marinova. It emerges from the analyzes that the contents of dry matter (27.66 ± 0.06%), total sugars (31.25 ± 0.6 mg / g) and fibers (8.21 ± 0.01%) are higher in ginger than in turmeric. The lipid contents of the two species are less than 8%. The results also reveal the presence of tannins, saponins, polyphenols, alkaloids and flavonoids. Ginger has a high content of total polyphenols (53.55 ± 0.45 mg EAG / g) than turmeric (35.25 ± 0.52 mg EAG / g). However, the flavonoid values are high in turmeric (92.52 ± 0.54 µg EQ / g) than ginger (86.27 ± 0.62 µg EQ / g). Both turmeric have revealed that ginger and turmeric are low in fat, reducing sugars, and high in fiber and polyphenols. Both rhizomes have the same protein content. The presence of secondary metabolites in the rhizomes of ginger and turmeric justifies the therapeutic importance of these two plants, hence the importance of consuming them to take full advantage of the beneficial effects of its active ingredients. However, the compounds vary from species to species.
Chicken diet cost represents up to 70 % of the production charges. Inputs, which are mostly imported products such as lysine, methionine, wheat bran are the cause of the expensive cost of foods. Wheat bran is not available in Côte d'Ivoire and could be efficiently substituted by cassava. Cassava is affordable and available all year round. The objective of this work was to determine the effects of the substitution of wheat bran by cassava flour on the growth of chickens. After administering ad libitum during 8 weeks the different food categories (starting and growing food), results showed that protein, fat, ash and calcium contents improved more with the addition of cassava for both starting and growing periods. The energy value of cassava-based feed was higher than that of foods containing wheat bran: 12 155 kJ / kg against 11 428 kJ / kg for the starting food and 12 586 kJ / kg against 11 577 kJ / kg for growth, respectively. Throughout the rearing period, the growth of chicken fed with the cassava-based diet was much higher than that of the chicken fed with the control diet. In the growing food, palmitic acid was the dominant saturated fatty acids with the cassava-based diet exhibiting higher values of saturated fatty acids. The content of unsaturated fatty acids from cassava (48.6 %) was slightly higher than the control diet (47.6 %). Except magnesium, macro-element concentrations were higher in the cassava-based diet than those of food control. Micronutrients such as manganese and zinc had a high value in cassava-based diet than the control diet. Hydrogen cyanide which is in the fresh pulp at 100 mg / kg, decreased at 1.8 mg / kg of dry matter in the start food and at 1.9 mg / kg of dry matter in the growth food. The substitution of wheat by cassava improves feed nutritional profile, also reduces the production cost, food industry will benefit from this up to 13, 36 % in start-up period and up to 13, 25 % in growing period.
Côte d'Ivoire's membership in Scaling Up Nutrition (SUN) is a momentum in a collective effort to improve the nutrition and nutritional status of the population. This nutritional status study is part of this process and aims to assess the nutritional status of children aged 6 to 59 months in the dietary department of the Regional Hospital of Daloa. To do this an evaluation of the nutritional status is carried out. For this purpose, the anthropometric measurements of the children were carried out. The survey found that acute malnutrition affects 44.34% of children aged 6 to 59 months receiving dietary services from the Regional Hospital of Daloa and 31.13% suffer from severe forms. In fact, children aged 6 to 59 months suffered from stunting, of which 38.68% were severe and 56.60% of children aged 6 to 59 months were underweight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
