Nutritional Assessment of Precooked Flour Formulated From Corn (Zea Mays), Soybean (Glycine Max) and Groundnut (Arachis Hypogaea) Flours Consumed In Côte D’ivoire (Published)
The purpose of this study was to enrich corn flour with soybean and peanut flour in order to formulate an enriched feed for children of weaning age. To do this, an enriched corn flour has been formulated by adding to corn flour, soybean and peanut flours. The flour thus composed was characterized physically and biochemically. Then, a growth and biometric study was conducted to evaluate the effect of enriched corn flour on young rats of Wistar strain in growing. The results of the physicochemical and biochemical study give contents in dry matter, protein, fat, ash, carbohydrate and energetic value of 89.44 ± 0.13, 17.85 ± 0.11%, 5.83 ± 1.72%, 1.85 ± 0.03 %, 62.31 ± 0.01% and 442.99 ± 0.05 Kcal / 100g respectively for enriched corn flour. The effect of compound meal on young rats gives the growth level for weight gain, feed efficiency, apparent digestibility, true digestibility, and biological value values of 2.91 ± 0.59 g / j, 0.33 ± 0.07, 86.45 ± 0.31%, 94.28 ± 0.13% 84.27 ± 0.37% respectively. At the level of the biometric study no abnormality was observed at the level of the regulating organs which are the kidneys, the liver, the heart and the spleen compared to the control diet. Nutritional assessment results showing better performance at the 5% threshold for the different nutritional parameters show that enriched corn meal could have a positive impact on children’s health and prevent the occurrence of illness such as kwashiorkor due to malnutrition. In addition, the fact that the nutritional parameters comply with the standards required shows that this food could be industrialized to facilitate its accessibility by all layers of society.
Phosphorus Adsorption Isotherms of Some Low Activity Clay Soils As Influenced By Soil Properties and Their Effect on Fertilizer P Recommendations and Yield of Soybean (Glycine Max (L.) Merr.) In Benue State, Nigeria (Published)
The relationship between labile P sorbed to the soil surface and solution P can be described by a quantity-intensity relationship which shows P sorption or desorption as a function of P in the equilibrium solution. Twelve soils in Benue state representing Alfisols, Ultisols and Inceptisols were therefore used to examine the influence of soil properties on the shape and placement of their adsorption curves and yield of soybean. Sorption characteristics were determined in 0.01 M CaCl2 solutions of various P concentrations. For each soil, the amounts of P that gave 0.025, 0.05, 0.075, 0.100, 0.125, 0.150, 0.175, 0.200, 0.225, 0.250 mg kg-1 solution concentrations were estimated from adsorption curves. In the greenhouse, 4 kg of soil from each location was placed in plastic pots. Amount of P estimated from sorption study was added as KH2PO4. The treatments were laid out in Randomized Complete Block Design (RCBD) and soybean seed variety (TGx 1448-2E) was planted and growth and development observed to maturity. Optimum solution P concentration (SPC) was determined for each soil in relation to yield. At harvest, SPC that gave highest grain yield was evaluated for each soil and the quantity of P required (SPR) to achieve this concentration was calculated. Consequently, Odoba would require highest P fertilizer application (604.84 Kg P ha-1), (Tor-Donga 112.31, Abeda-Mbadyul 105.93) would require medium fertilization, (Utonkon 72.75, Katsina-Ala and Ofugo 67.64, Akoodo-Mbakor and Nor 61.26, Ogyoma 39.56, Otobi 33.18 and Abaji-Kpav 22.97 Kg P ha-1)would require low fertilization while Vanam (2.55 Kg P ha-1) would require the least.
