Nono is a spontaneously fermented yoghurt-like milk product consumed is a staple food commodity in parts of the Sub-Saharan West Africa. Nono is usually consumed along with 'Fura' as 'Fura da Nono' in Nigeria. Studies on physicochemical and bacteriological qualities were carried out on samples of Nono obtained from 5 different sources in Ado-Ekiti, Nigeria. The Nono samples were found to be nutritious, containing moderate levels of ash, crude fat, crude protein and carbohydrate. The pH of the Nono samples was relatively low (4.04 ±0.04), while the density and specific density were close to that of distilled water at room temperature. Total aerobic plate count of Nono samples was 1.8 ±0.02 × 106 CFU.mL -1 . A total of 15 bacteria species namely Eubacterium nodatum, Bacillus subtilis,
A feeding trial was conducted to assess the level of inclusion of high fibre sunflower seed cake (HFSSC) protein as ror soyabean cake protein replacement for soybean cake protein in the diets of broiler chicken at 0,25,50,75, and 100%. At the starter phase feed intake and feed efficiency ratio were significantly (p,0.05) increased as the level of HFSSC increased in the diets . weight gain and protein efficiency ratio were however significantly (p,0.05) reduced when over 25% of HFSSC was included in the diets . Atthe finisher phase the same trend was observed except that weight gain and protein efficiency ratio were significantly (p0.05) reduced when over 50% HFSSC was included in the diet. Significantly (p<0.05) differences were observed in live weight, plucked and dressing percentages at the starter and finisher phases. Reduction in abdominal fat deposition was obtained at the starter and finisher phases while gizzard weights wee significantly (p<0.05) increased. The result of this study show that 50% soybean cake protein in the diets of broiler chicken can be replaced by HSFFC.
Introduction : Heavy metals are known to cause deleterious effects on human health through food chain. Aims: The study is aimed at assessing heavy metal concentrations in the tissues of four highly consumed fish species and to evaluate the potential health risks associated with their consumption. Materials and Methods: The concentrations of Cu, Cd and Pb were analyzed in the tissues of Titus (Scomber Japonicus), Croaker (Pseudolithus Elongatus), Scumbia (Ilisha Africana) and Shrimps (Pipeus Notialis) by atomic absorption spectrophotometry (AAS) after digestion of the samples. Results: The results showed that Cd was not detected in the tissues of all fish species. There were variations among Cu and Pb concentrations in the tissues of the fish species. Cu had the highest concentrations (1.00 µg/g) in the tissues of croaker and shrimps respectively while Pb had the lowest concentrations (0.25 µg/g) in the tissues of Scumbia . The levels of all metals in the present study were lower than the limits permitted by Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO), European Community Regulation (EU) and European Commission (EC). Assessment of noncarcinogenic health hazard using Target hazard quotient (THQ) and hazard index (HI) indicated no concern from consumption of these fish species. The estimated daily intake (EDI) of the studied metals through fish consumption was below the permissible tolerable daily intake. Conclusion: It can be concluded that there is no potential human health risk from consumption of the selected fish species. Keywords: Heavy metals, Hazard index, Target hazard quotient.
