Proximate study, mineral and anti-nutrient composition of Moringa oleifera leaves harvested from Lafia, Nigeria: potential benefits in poultry nutrition and health

Abstract: The leaves of Moringa oleifera were harvested from Lafia in Nasarawa State of Nigeria during the rainy season in June 2011 for proximate, mineral and phytochemical analysis. The results of proximate analysis revealed the presence of high crude protein (17.01% plus minus 0.1) and carbohydrate (63.11% plus minus 0.09). The leaves also contained appreciable amounts of crude fibre (7.09% plus minus 0.11), ash (7.93% plus minus 0.12), crude fat (2.11% plus minus 0.11) and fatty acid (1.69% plus minus 0.09). The total ash content showed it contained minerals, Ca (1.91% plus minus 0.08), K (0.97% plus minus 0.01), Na (192.95 plus minus 4.4), Fe (107.48 plus minus 8.2), Mn (81.65 plus minus 2.31), Zn (60.06 plus minus 0.3) and P (30.15 plus minus 0.5) parts per million (ppm). Magnesium (0.38% plus minus 0.01) and copper (6.10 plus minus 0.19) were the least. The results of phytochemical analysis and anti-nutrients showed presence of tannins (21.19% plus minus 0.25), phytates (2.57% plus minus 0.13), trypsin inhibitors (3.0% plus minus 0.04), saponins (1.60% plus minus 0.05), oxalates (0.45% plus minus 0.01) and cyanide content (0.1% plus minus 0.01). The presence of these essential nutrients and minerals implies Moringa oleifera leaves from Lafia, Nasarawa State could be utilized as a source of feed supplement to improve growth performance and health status of poultry. The benefits of essential nutrients and minerals in maintaining good health were also highlighted in this study.

In the present work studies have been carried out to investigate the antibacterial properties of ZnO nanoparticles (NPs). Various tests were performed to assess the antibacterial activity of cotton fabrics coated with ZnO nanoparticles against Gram positive Staphylococcus aureus and Gram negative Escherichia coli. The antibacterial activities of the fabrics were assessed semi-quantitatively by the agar diffusion method and the shake flask method (nutrient broth) and quantitatively by the shake flask method (saline) and the absorption method (ISO 20743:2007). The results showed a significant antibacterial activity of ZnO nanoparticles coated onto fabrics against both bacteria, with a slightly higher activity against Staphylococcus aureus as compared to Escherichia coli.

Formulation and nutritional quality of infant formula produced from germinated popcorn, Bambara groundnut and African locust bean flour.

Abstract: The aim of this present study was to produce and evaluate the nutritional quality of complementary foods from popcorn, African locust bean and Bambara groundnut. The popcorn, bambara groundnut and African locust beans were obtained locally in Akure, Nigeria. The seeds were germinated, oven dried, milled and sieved into flours. The flours were mixed as follows: GPA (70% popcorn, 30% African locust bean), GPB (70% popcorn, 30% bambara groundnut) and GPAB (70% popcorn, 20% bambara groundnut, 10% African locust bean). The chemical composition, functional properties, sensory attributes and nutritional qualities of the food samples were determined using standard methods. The protein content of the food samples range between 23.85±1.54 – 28.84±1.02 g/100g, energy values, 434.47±2.04 444.11±2.47 and appreciable amount of minerals. The total essential amino acid (TEAA) composition range from 27.63 to 31.09 g/100g. The calculated biological value range from 29.84 to 42.01 % . The oxalate, tannin, phytate and trypsin concentration of the food samples were reduced; while the choking property of the popcorn-based diets was eliminated with respect to the survival of experimental animals. The calculated molar ratios for [Ca][Phytate]/[Zn], phytate:calcium and phytate:iron were less than the critical values For sensory attribute, the GPB was rated highest in terms of overall acceptability over the JMBFS / Ijarotimi and Keshinro 2012 : 1 (6) 1358-1388 1359 GPA and GPAB, but rated less when compared with ogi and cerelac. It could be concluded that GPB had a better nutritional quality based on the overall ranking using protein, energy, Ca/P ratio, TEAA, biological value and sensory attributes indices.
