Cassava intake and vitamin A status among women and preschool children in Akwa-Ibom, Nigeria

Background As part of the HarvestPlus provitamin A-biofortified cassava program in Nigeria we con- ducted a survey to determine the cassava intake and prevalence of vitamin A deficiency among children 6-59 months and women of childbearing age in the state of Akwa Ibom. Methods A cluster-randomized cross-sectional survey was conducted in 2011 in Akwa Ibom, Nigeria. The usual food and nutrient intakes were estimated using a multi-pass 24-hour recall with repeated recall on a subsample. Blood samples of children and women were collected to analyze for serum retinol, serum ferritin, and acute phase proteins as indicators of infection. Vitamin A deficiency was defined as serum retinol < 0.70 ? mol/L adjusted for infection. Results A total of 587 households of a mother-child dyad participated in the dietary intake assess- ment. Cassava was very widely consumed in Akwa Ibom, mainly as gari or foofoo . Daily cassava consumption frequency was 92% and 95% among children and women, respec- tively. Mean ( ± SD) cassava intake (expressed as raw fresh weight) was 348 ± 317 grams/ day among children and 940 ± 777 grams/day among women. Intakes of most micronutri- ents appeared to be adequate with the exception of calcium. Median vitamin A intake was very high both for children (1038 ? g RAE/day) and women (2441 ? g RAE/day). Red palm oil and dark green leafy vegetables were the main sources of vitamin A in the diet, with red palm oil alone contributing almost 60% of vitamin A intake in women and children. Preva- lence of vitamin A deficiency ranged from moderate (16.9 %) among children to virtually non-existent (3.4 %) among womenConclusion Consumption of cassava and vitamin A intake was high among women and children in Akwa Ibom with a prevalence of vitamin A deficiency ranging from moderate in children to non-existent among women. The provitamin A biofortified cassava and other vitamin A inter- ventions should focus dissemination in states where red palm oil is not widely consumed.Background As part of the HarvestPlus provitamin A-biofortified cassava program in Nigeria we con- ducted a survey to determine the cassava intake and prevalence of vitamin A deficiency among children 6-59 months and women of childbearing age in the state of Akwa Ibom.

Nutrient Intakes and Nutritional Status of Mothers and their Under-Five Children in a Rural Community of Oyo State, Nigeria

Malnutrition in sub-Saharan Africa contributes to high rates of childhood morbidity and mortality which make it a public health concern in Africa. This study assessed the nutrient intakes and nutritional status of mothers and their under-five children in a rural community of Oyo State, Nigeria. A total of 500 households with a mother and child pair were sampled using a multi-stage sampling procedure. Information on household socio-economic status, hygiene practices, breastfeeding practices and clinical observation for signs of malnutrition were collected using pre-tested semi-structured questionnaires by trained interviewers. Weight for age (WAZ), weight for height (WHZ), and height for age (HAZ) for underweight, wasting and stunting, respectively were calculated and assessed by Epi Info software using the NCHS/WHO international reference values. BMI (weight/height2) of mothers were also constructed from the measurements of mothers’ weights and heights. The waist/hip ratio of mothers was also determined. An interactive 24 h recall repeated for three days was used to obtain data on food and nutrient intakes of the women. Information on foods consumed was converted into quantitative data of nutrients using Food Composition Table. The result showed a high proportion (81%) of mothers ate three times daily while 14% ate twice and 5% ate more than thrice daily. The mean daily intakes of calcium, vitamins A, B6, B12, niacin, and folate were found to be inadequate compared with the Recommended Intakes. The WHR of the mothers indicated that majority had low risk. Most of the mothers (69.2%) were normal, underweight 9.6%, overweight 15.8% and obese 5.4%. About 37% of the children were stunted, 18% were underweight and 14.3% were wasted. BMI correlated negatively with age (r = -0.41; p &lt;0.05), and positively with education (r = 0.22; p&lt;0.05) and income (r = 0.45; p &lt;0.05). Clinical observation revealed PEM prevalence in 12% children while eyes pallor and palm pallor were present in 15% and 20% respectively. The nutritional status of mothers and their under-five children is poor with respect to the overall food consumption and micronutrient intake. Consequently, nutrition programmes in this area should include effective measures to promote nutritional status of mothers and children

EFFECTS OF ASCORBIC ACID SUPPLEMENTATION ON THE PERFORMANCE INDICES OF STARTER PULLETS IN A HOT - HUMID ENVIRONMENT

Two studies were conducted to evaluate the nutritional effects of supplementary ascorbic acid (AA) at levels of 0, 100, 200, and 300 mg/kg in the diets of starter pullets reared at different seasons (harmattan season and rainy season) in a hot humid environment. Two hundred and forty day-old Harco pullet chicks were used in each trial, they were randomly assigned to each of the four dietary treatments in three replications of twenty chicks per replicate. Each trial lasted 8 weeks during which data were collected and a 2 X 4 factorial arrangement was employed in the analysis of data collected.&nbsp; Results showed significant (p&lt;0.05) effect of treatments on feed conversion ratio of birds fed dietary treatments. Season of presentation of ascorbic acid significantly affected (p&lt;0.05) feed intake with higher value obtained in the rainy season compared to the dry season (41.89g vs. 39.59). &nbsp

CONSUMPTION PATTERN OF MAIZE BASED DISHES IN FOUR AGRO-ECOLOGICAL ZONES OF NIGERIA

The global picture had dramatically changed the lifestyles of Nigerian citizens pushing them into various fast-eating cultures with more instant and tasty meals, and the attendant gradual relegation of our traditional rich eating cultures. Studies were carried in eight Local Government Areas of Nigeria from the four Agro-Ecological Zones (AEZs) namely: moist savanna (Oyo State), humid forest (Lagos State), mid-altitude (Abuja) and dry Savanna (Kaduna State). Stratified multistage sampling technique with structured questionnaires from 1641 respondents and focus group discussions (FGDs) were employed to identify the maize-based dishes consumed and determined the frequency of consumption. The demographic characteristics revealed that 54.8% of the respondents were male. Residents in the rural area were more (56.8%) and majority of the respondents were between the ages of 26-45 years (67.6%), while more Christians (57.88%) participated in the study than any other religion. Results showed that thirty–two maize-based dishes were identified, of which ten were frequently consumed. Ogi was the most popular maize-based dish (73.5%) consumed in the AEZs while corn pudding was the least consumed (28.5%). There were significant differences (p&lt;0.05) in all the sensory attributes measured. The low consumption of majority of the maize-based dishes raises concern for the current campaign on mobilizing local biodiversity which has been reported to be one of the food based intervention strategies for solving nutrition problems among population groups

Nutritional Composition and Sensory Properties of Iron Fortified Fufu Flour

Cassava fufu flour was fortified with iron Sulphate, iron fumarate and sodium iron EDTA at three concentrations (25, 35 and 45 mg/kg) in this study. The samples were analyzed for proximate and minerals composition as well as sensory and pasting properties.&nbsp; There were significant differences (p&lt; 0.05) in the proximate and pasting properties of iron-fortified fufu samples compared to unfortified samples. Iron contents of unfortified samples ranged from 8.50 to 11.36 mg/kg compared to iron contents of fortified fufu. There were no significant differences (p&gt;0.05) in sensory taste, texture and odour of unfortified and fortified samples.&nbsp; In terms of overall acceptability, panelists rated unfortified cassava products higher followed by samples with 25 mg/kg NaFeEDTA and iron sulphate respectively. The rate of return on investment for iron fortified fufu flour was 1.41. The study has shown that the use of iron fortified cassava products has potentials for practical application and economic viability. &nbsp

Performance and nutrient utilization of cockerel finishers fed graded levels of rice milling waste

An experiment was conducted to investigate the effects of rice milling waste (RMW) on performance and nutrient utilization of cockerel finishers. One hundred and fifty 9-week old Black Harco cockerels were raised on five experimental diets where RMW replaced maize at graded levels and designated diet 1 (0% RMW); diet 2 (15% RMW without palm oil); diet 3 (30% RMW without palm oil); diet 4 (15% RMW with palm oil) and diet 5 (30% RMW with palm oil). The diets were formulated to be isonitrogenous and isoenergetic. Each diet was fed to a group of 30 birds for a period of ten weeks. Records were maintained on body weight gain, feed intake and mortality while digestibility trials were conducted at the end of the experiment. There was no significant difference (P&gt;0.05) in weight gain between treatments, however dietary treatments had significant (P&lt;0.05) effect on feed intake, feed to gain ratio and feed cost. Apparent crude protein retention and digestibilities of dry matter, ether extract, crude fibre and ash were significant for ail dietary treatments. From the study it was concluded that RMW can he included in cockerel finisher diet at up to 30% level when the diet is supplemented with palm oil. Keywords: Cockerels, rice milling waste, utilizatio
