Acceptability of egg powder among nursing mothers in rural areas of Ijebu North local government area of Ogun State, Nigeria
(2018) Tijani, S. A.
Eggs are among the most nutritious foods, cheapest source of protein, vitamins and minerals. However, fresh egg is fragile and its quality deteriorates easily. Egg powder adds consistent performance to the list of attributes of the commodity hence the need to evaluate the acceptability of egg powder among nursing mothers as a source of protein. The study was carried out in rural areas of Ijebu North Local Government Area of Ogun State. Random sampling technique was used to select 120 respondents across five maternity health centres. Interview schedule was used to collect data. Data were analysed using both descriptive and inferential statistics at α0.05. Findings revealed that 62.5% of the respondents had low level of awareness about egg powder, more than half (55.8%) had unfavourable disposition towards egg powder, resulting in 60.0% of them having low acceptability for its use. Non-availability of egg powder (50.8%) and lack of information on egg powder (50.0%) were major constraints to egg powder consumption in the study area. Significant relationship existed between respondents’ income (χ2 = 0.184), level of education (χ2 = 0.233), awareness (r = 0.229), perception of egg powder (r = 0.246) and the level of acceptability of egg powder. There was a low level of egg powder acceptability in the study area. Hence, there is a need to create awareness on the nutritive value of egg powder in the study area.
Physical characteristics, nutritive value and preference of zebu heifers for ensiled mixtures of corn cob, cassava peel and urea
(2015) Olorunnisomo, O. A.; Ososanya, T. O.
In order to improve the feeding quality of corn cob and cassava peel for zebu cattle, a mixture of corn cob-cassava peel was ensiled with 0, 1, 2, and 3% of urea. Physical characteristics, chemical composition and in vitro digestibility of the silage mixtures were determined in a laboratory trial while the preference of cattle for the mixtures was evaluated using twelve Sokoto Gudali heifers in a cafeteria feeding trial. The experimental design adopted was the completely randomized design. Silage colour changed from white to yellow; smell from very pleasant to pungent; and texture from very firm to firm as the level of urea in the silage increased. The pH increased from 3.80 to 6.00 as level of urea in the mixture increased. Crude protein (CP) content of silage increased from 8.50 to 17.52% while acid detergent fibre (ADF) decreased from 34.13 to 30.90% as level of urea in the silage mixture increased. Organic matter digestibility (OMD) varied from 55.44 - 60.45%, and increased with addition of urea. Preference of zebu heifers for corn c'ob-cassava peel silage varied from 13.81 - 38.87%. Acceptability of silage reduced significantly as level of urea increased. Addition of urea to corn cob- cassava peel silage enhanced CP content and digestibility but physical attributes and acceptability of silage by cattle were adversely affected.
Quality and acceptability of velvet bean (mucuna pruriens) foliage ensiled with whole plant maize by West Africa dwarf sheep
(2014) Alabi, B. O.; Ososanya, T. O.; Olorunnisomo, O. A.
This experiment was conducted to determine the suitability of Velvet Bean Foliage (VBF) and Whole Plant Maize (WPM) silage as dry season feed for ruminants in Southwest of Nigeria. In this study, WPM was ensiled with five levels of VBF (0, 25, 50, 75 and 100%). Physical characteristics, temperature, pH and proximate composition of the silages were assessed after 21 days of ensiling. Preference for the silage by ruminants was determined using twelve West African dwarf (WAD) rams. Results revealed that pH, temperature and physical characteristics of all silages were within acceptable range except for VBF -100 which did not make good silage. The appearance, smell and texture of all the silage mixtures compromised increasing level of VBF while the pH increased. The pH of the silage varied from 3.92-7.98. Dry matter (DM), crude protein (CP) and crude fibre (CF) concentration in the silages ranged from 20.67 - 26.65, 8.02 - 15.77, 26.42 - 1926g/100g, respectively. The DM and CF of the silages reduced with increasing level of VBF in the mixture while the CP increased. Coefficient of preference (CoP) for the silage varied from 0.79 to 1.13 while percentage preference varied from 15.58 - 22.50%. The coefficient of preference (CoP) was above unity for VBF (0, 25, 50 and 75) but less than unity for VBF- 100, showing that rams preferred silage with whole plant maize to sole VBF. This result suggests that quality of Whole plant maize silage improved when velvet bean foliage was added; however, acceptability by WAD rams was compromised.
Silage characteristics and preference of sheep for wet brewer's grain ensiled with maize cob
(Fundación CIPAV, Cali, Colombia, 2015) Ososanya, T. O.; Olorunnisomo, O. A.
In order to meet the shortfall in feed supply and provide adequate nutrition for sheep during the dry season, wet brewer’s grain (WBG) was ensiled with 0, 10, 20, and 30 % of crushed maize cob (MC). The physical characteristics, pH and chemical composition of the silage mixtures were determined at 21 days of ensiling. Acceptability and preference of sheep among the silage mixtures were determined in a cafeteria feeding trial using eighteen West African dwarf (WAD) sheep. The experimental design adopted was the completely randomized design. The colour, smell and texture of the mixtures showed that all silages had acceptable physical attributes. The pH of silage varied from 3.40 - 3.80, indicating that the silage mixtures were adequately fermented. Silage scores however revealed that the best physical attributes were attained at 20 % inclusion of maize cob to WBG. Dry matter (DM) content of silage was 26.88, 31.44, 36.69, 43.50% while crude protein (CP) content was 23.44, 19.11, 14.00, and 12.00% for silage with 0, 10, 20 and 30% of maize cob respectively. Neutral detergent fibre increased from 40.33 - 62.67 % and acid detergent from 25.00 - 39.67% with increasing level of maize cob in the mixture. The coefficient of preference (CoP) and percent preference showed that WBG silage with 10% MC was more acceptable and preferred by sheep than other silage mixtures. While physical attributes of silage showed that the optimum level of MC inclusion was 20%, animal preference indicate that this level was less acceptable to sheep. Sheep may require more time to adapt to higher levels of MC in the silage mixture.
