The most commonly used bird eggs are those from chicken. In Nigeria, the domestic foul dominates the poultry industry. Of the 120 million indigenous poultry population in Nigeria, the domestic fowl constitutes about 91 % of this. For this reason, the present work tried to evaluate the nutritional levels of the lipid composition of the free-range fertilized cooked chicken eggs. Five eggs were involved in the study and they were collected at once. The following experimental procedures were carried out on the yolk and the albumen using standard analytical methods: crude fat determination, preparation of methyl esters and fatty acid analysis. Also determined was the quality assurance of the determinations to ensure their accuracies, calculation of uncertainty interval percentage (UIP) particularly for the fatty acid values. Statistical evaluations carried out included: linear correlation coefficient (rxy), coefficient of determination (rxy 2 ), linear regression coefficient (Rxy), coefficient of alienation (CA) and index of forecasting efficiency (IFE). The study reports the nutritional values of the lipid composition of the free-range chicken eggs analyzing separately the yolk and the albumen. The yolk was 32.8 % of the total egg weight while the albumen was 53.8 %. The total crude fat in yolk was 22.9 g/100 g whilst it was 0.001 g/100 g in albumen. The total fatty acid in yolk was 19.0 g/100 g; it was 0.00083 g/100 g in albumen. The SFA level was 35.0 % in total fatty acids in yolk; it was 31.8 % in albumen. Total monounsaturated fatty acids (MUFA) in yolk was 43.5 % but 42.9 % in albumen. Total n-6 PUFA was 21.8 % in yolk and 25.2 % in albumen. The PUFA/SFA was 0.62 in yolk and 0.79 in albumen. Lecithin was high in yolk [115 mg/100 g; 46.0 %] but at trace level [23.3e-3 mg/100 g; 63.1 %] in albumen. Sterol was not detected in the albumen but total sterol in the yolk was 386 mg/100 g having cholesterol level of 86.3 mg/100 g (22.4 %). The levels of MUFA + PUFA in yolk was 65.3 % and 68.1 % in albumen showing that the chicken egg could be classified as being made up majorly of unsaturated oil. Free-range laying hens are given outdoor access instead of being contained in crowded cages; this gives them wide range of various feeding opportunities. This report showed the free-range chicken eggs yolk to be far more concentrated in crude fat; total fatty acids; SFA; MUFA; n-6 PUFA; high PUFA/SFA; high lecithin; high cephalin; high stigmasterol and cholesterol than the corresponding albumen. The cholesterol level was also below the average recommended level.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"55 1","pages":"374-384"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86096563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parameters measured were feed intake, weight gain, feed conversion efficiency, mortality, egg productivity (total number of eggs), egg infertility and egg fertility. There were significant differences (P<0.05) in feed intake of birds. Birds from Northern region had the highest intake of 78.3 ± 3.54 g/bird/day followed by birds from Upper East (74.4 ± 3.54 g/bird/day) and Upper West (62.9 ± 3.54 g/bird/day). Daily weight gain and feed conversion efficiency of the birds from all three regions were not significantly different (P>0.05). Birds from Upper West region suffered the highest mortality (17.5%), with the least being those from Upper East (1.25%). Total eggs laid during the period were 362 eggs for Northern region, 310 eggs for Upper East and 266 for Upper West. These also showed significant differences (P五0.001). Egg fertility levels were satisfactory in birds from all three regions (77.4-81.9%). There were distinctive differences in almost all the parameters measured.

A pot trial was carried out to evaluate the effects of lime (CaCO3) from three liming materials on soil Al toxicity and the yield of maize (Zea mays L.). Two cement by-products (Agri-56 and Filler) and a conventional liming material (Limbux) were used. The acid neutralizing values for Limbux, Agri-56 and Filler were 126, 88 and 34% CaCO3 equivalent, respectively. Five rates of lime equivalent: 0, 2, 4, 8 and 16 tons CaCO3 ha -1 and the three liming materials were applied in combinations as treatments. Agri-56 was as efficient as Limbux in neutralizing Al toxicity. Aluminium saturation decreased from 83% to 31, 37and 69% for Limbux, Agri-56 and Filler, respectively when 2 tons CaCO3 ha -1 was applied. Limbux and Agri-56 increased the soil pH from 4.3 to 7.1 and 6.5, respectively at equivalent rate of 16 tons CaCO3 ha -1 . There was a 53.5 and 67.2% increase in maize yield for Limbux and Agri-56, respectively when 2 tons CaCO3 ha -1 was applied.

The coefficient of friction was highest on plywood with 0.37 for seeds and 0.66 for kernel while the lowest coefficient of friction was recorded on stainless steel, 0.32 and 0.43 for seeds and kernels respectively. For all surfaces the kernels recorded the highest coefficient of friction. Also, the kernel angle of repose was 26.2 0 which are higher than angle of repose recorded for seeds, 19.2 0 .

In this study therefore, it was enriched with partially defatted peanut paste by partially substituting the maize with the groundnut paste in varying proportions ranging from ten to fourty percent paste. The various mixtures obtained were separately processed into snacks following essentially the traditional method of production, involving thorough mixing, dough formation and deep frying in vegetable oil. The products obtained were analysed for proximate composition, some physico-chemical properties and pasting characteristics. The sensory attributes were also evaluated. Results obtained indicated substantial increases in the level of protein with increases in the level of substitution with peanut paste, ranging respectively from 12.33 to 23.77% in the zero and 40% levels of substitution with peanut paste. This may be an indication of the potentials of the peanut paste in improving the nutritional status of the snack. While similar trends were observed with respect to the fat contents, the levels of ash, crude fibre and carbohydrate showed a reverse trend. The swelling capacity of the resulting flour mixtures before frying decreased in value with increases in the level of substitution, but increases, although only slightly in the values of water absorption capacity respectively. Slight increases were also recorded with respect to the generally low values of bulk density, an indication of a possible positive impact on the ease of packaging and transportation of products. There were no significant changes in the pasting properties of the resulting flour mixes regardless of the level of substitution. Sensory evaluation of the products obtained indicated that the greater the level of substitution with the defatted peanut paste in the mixture, the more acceptable the product is to consumers.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"44 1","pages":"280-286"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74139895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study therefore examined the problems and prospects of cassava production in Oyigbo L.G.A. Multistage sampling technique was used in the data generation exercise. Six (6) villages were randomly selected from the seventeen villages that make up Oyigbo L.G.A. Descriptive statistical tools, such as frequency and percentages were used in analyzing the data. Results showed that majorities (65.6%) of the cassava farmers were above 51 years which implied that able bodied young men and women were scarcely available for farm work. The result further showed that about 50% of the farmers received only primary education. Most of them rented their farmlands, used old cassava stem cuttings and were scarcely visited by extension agents. It is therefore recommended that adequate infrastructural facilities such as good roads and electricity, etc be made available in the rural areas to reduce the migration of the youths to urban centers in search of non existent white collar jobs. Credit liberalization policy should also be implemented by the Government to enable the farmers increase their farm sizes and purchase improved planting materials. Adult education programmes should be intensified by the Government to raise the educational standards of these farmers. The training of more extension agents is hoped to increase the number of extension contacts among these smallholder cassava farmers.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"36 1","pages":"296-301"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73587279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
