Abstract: Se llevó a cabo un estudio en todo el estado de Jigawa en la república de Nigeria durante noviembre-diciembre, parte de la estación de seca; donde la malaria es una de las principales causas de morbilidad y mortalidad, especialmente entre los ni os menores de 5 a os y las mujeres embarazadas. Este estado presenta 2 estaciones climáticas una seca de octubre a mayo y otra de lluvia de junio a septiembre. Se muestreó un total de 112 cuerpos de agua, solo 18 en 9 gobiernos locales resultaron positivos a mosquitos. Los sitios de cría identificados para Anopheles correspondieron a campos de arroz, peque o hueco en la tierra, pisadas de animales, peque os estanques, terrenos con pasto inundados y presa de tratamiento de agua, para un total de 10. Contrario a lo que siempre se ha reportado sobre la presencia de Anopheles en aguas limpias, se encontraron criando en aguas con alta polución que contenían heces fecales humanas y desperdicios de basura, representadas por alcantarillas abiertas en las localidades. A study was conducted in the state of Jigawa, Republic of Nigeria, from November to December in the dry season, where malaria is one of the main morbidity and mortality causes particularly in under 5 years-old children and pregnant women. This state had two climate seasons: dry from October to May and rainy from June to September. A total of 112 water bodies were sampled and just 18 in nine local governments were positive to mosquitoes. Breeding sites for Anopheles were rice fields, small holes in land, animal footsteps, small ponds, flooded pasture fields and water treatment dam, among others, to amount to 10 sites. Contrary to what has always been reported about the presence of Anopheles in clean waters, they were also breeding in highly polluted waters containing human faeces and garbage and located in open sewers. Key words: Breeding sites, Anopheles, malaria, Nigeria.

Trends in Agricultural Economics , 2011,
Abstract: This study has examined the influence and relationship of socio-economic characteristics of the Fadama Resource Users on conflicts incidence in Fadama areas of Bauchi State, Nigeria. Stratified multistage random sampling was employed resulting to 120 respondents (60 arable farmers and 60 pastoralists). Data were analyzed using correlation and multiple regressions. From the arable farmers, land size, total cost and saving had strong but negative relationship with conflict incident at p<0.001. Education was also negative but significant at p<0.01. Herd size, accessibility to grazing reserve, saving were significant at p<0.001 for the pastoralists. The coefficient of awareness of grazing reserve, experience and education were significant at p<0.01. Gender and saving were statistically significant at p<0.01 and p<0.05, respectively in respect of their influence on conflict for the arable farmers. Education, total cost and savings were all significant at p<0.001, whereas accessibility to grazing reserves were significant at p<0.05 for their strong sensitivity to conflict incident. The outcome of the study revealed strong relationship of all the selected variables with incident of conflict except marital status and experience for the arable farmers. Gender savings, education, accessibility to grazing reserves and total cost had strong influence in conflict incidences. Therefore, the Fadama area communities especially that of the pastoralist needed improvement in their education status and more grazing reserves should be provided by the relevant authority to ease accessibility to pasture and invariably reduce conflict incidences.

Farm Planning Model for Sustainable Vegetable Crop Production in the Eastern Part of Kogi State, Nigeria
M.H. Sani,U. Haruna
Journal of Agronomy , 2010,
Abstract: The study examined the farm planning model for sustainable vegetable crop production in the Eastern part of Kogi State, Nigeria. Specific objectives of the study were to: identify the various cultural practice, irrigation sources and application methods and also to determine the net benefits of the farmers with respect to vegetable crop production. Multi-stage random sampling technique was used. From the study area, three local government areas were randomly selected. In each local government area, two villages each where there is extensive irrigation cultivation were purposively selected making a total of 6 villages. Samples of twenty farmers from each of the 6 villages were selected giving a total sample of 120 farmers in all. Data were collected with the assistance of trained enumerators using structured questionnaire, interview and on-the-farm observation. Farm budget planning model was used to determine the net benefits of the vegetable crop production by the farmers. The result reveals that gross total variable cost was N23, 378.59 and gross total fixed cost was 603.80 representing 97.48 and 2.52% of the gross total cost of N23, 982.39, respectively. Cost of fertilizer and fuel constitutes 30.62 and 38.38%, respectively of the gross total variable cost. The gross returns was N447,136.00 having the highest contribution margins of 51.47 and 27.86% from onion and pepper, respectively. The results of the profitability index revealed that RRI was 1,764.43%; RRFC was 70,181.75%; RRVC was 1,910.00% and CTO was 18.64. The result of RRI which is above 100% signifies that the 120 sample farmers do not require additional capital for crop production. The RRVC and RRFC were also above 100% meaning that some of the vegetable crop production inputs are high and as such needed to be subsidized in order to increase CTO of the sample farmers. The CTO has a value of 18.64 implying that for every additional Naira spent by the sampled farmers on inputs will yield about N18.64 net returns. The study recommend the need for the Government to subsidize some of the farm inputs based on the results of RRVC and RRFC which were above 100% revealing that some of the vegetable crop production inputs are high.

Abstract: Field experiments were carried out between 2007 and 2008 rainy seasons at the Teaching and Research Dry Land Farm of the Usmanu Danfodiyo University, Sokoto, to investigate the effects of planting date (mid may, early and late June) and weeding regimes (weedy check, weeding once, weeding twice and weed free) on the growth and yield of sesame (Sesamum indicum L.). The experiment was laid out in a Randomised Complete Block Design (RCBD) with three replications. Results obtained indicated that planting date had significant (P<0.05) influence on plant height, number of branches and number of capsules per plant, seed yield kg/ha and weight of 100 seeds. Weeding regime also significantly(P<0.05) affected plant height, weight of capsules and number of capsules per plant. KEYWORDS: Planting date; Sesame; Seed yield; Weeding regime

Abstract: The conversion of waste obtained from agricultural processes into biocompatible materials (biomaterials) used in medical surgery is a strategy that will add more value in waste utilization. This strategy has successfully turned the rather untransformed wastes into high value products. Eggshell is an agricultural waste largely considered as useless and is discarded mostly because it contributes to pollution. This waste has potential for producing hydroxyapatite, a major component found in bone and teeth. Hydroxyapatite is an excellent material used in bone repair and tissue regeneration. The use of eggshell to generate hydroxyapatite will reduce the pollution effect of the waste and the subsequent conversion of the waste into a highly valuable product. In this paper, we reviewed the utilization of this agricultural waste (eggshell) in producing hydroxyapatite. The process of transforming eggshell into hydroxyapatite and nanohydroxyapatite is an environmentally friendly process. Eggshell based hydroxyapatite and nanohydroxyapatite stand as good chance of reducing the cost of treatment in bone repair or replacement with little impact on the environment. 1. Introduction Agricultural waste is any waste being generated from different farming processes in accumulative concentration. Adequate utilization of agricultural waste reduces environmental problems caused by irresponsible disposal of the waste. The management of agricultural wastes is indispensable and a crucial strategy in global waste management. Waste of any kind in the environment when its concentration is in excess can become a critical factor for humans, animals, and vegetation [1]. The nature, quantity, and type of agricultural waste generated vary from country to country. The search for an effective way to properly manage agricultural waste will help protect the environment and the health quality. For sustainable development, wastes should be recycled, reused, and channelled towards the production of value added products. This is to protect the environment on one side and on the other side to obtain value added products while establishing a zero waste standard. The utilization of the waste is a priority today in order to achieve sustainable development [2]. One way that adds great value to agricultural waste is its utilization as a biomaterial used in medical surgery and therapeutics. The production of biocompatible material or biomaterial from agrowaste has added a different dimension to the utilization of agricultural waste for value added product. This is possible because some of this waste

Abstract: In recent years, several attempts have been made in designing planar array antennas with high directivity. This paper is aimed at investigating the impact of element spacing on the directivity of planar array of monopole antenna. The directivity of antenna with reduced grating lobes can be obtained by carefully varying the inter-element spacing of array antenna. Based on this conception, this paper presents the investigation carried out on the relationship between inter-element spacing and the directivity of planar array of monopole antenna. It went further to highlight the effect on the total fields radiated by the antenna. The inter-element spacing is one of the most important antenna parameters that determine the directivity of the antenna. For a planar array of monopole, the directivity can be improved by varying the inter-element spacing. Four elements uniform planar array antenna and Hadamard matrix method was used to determine element positioning in the array matrix. The simulated results obtained using Matlab, showed that good directivity was obtained by using element spacing between 0.1λ - 0.5λ. Increasing the spacing beyond 0.6λ - 1.0λ also improved the directivity, but generated many grating lobes. As inter-element spacing increased, the grating lobes increased in size, number and levels. The study, therefore, inferred that the best directivity (radiation pattern) can only be obtained when the element spacing is within 0.1 - 0.5λ.

Abstract: There is a scarcity of information on the effect of vaccine against aspergillosis in Zaria and Kaduna areas. Thus, this study was conducted to determine the efficacy of an Aspergillus fumigatus germling vaccine. The methodologies used in this study included Aspergillus spore production, determination of LD50, preparation of the germling vaccine and testing the efficacy on broiler chicks. Three groups of 4 days old broilers were exposed to 4.2-5.8x108 cfu g-1 lung tissue of A. fumigatus. The calculated amount of A. fumigatus that killed 50% of the broilers was 5.8x107.4. A. fumigatus was recovered 4 weeks post exposure. A germling vaccine of A. fumigatus was administered to 4 days old broilers using the ocular route. The trial vaccine showed 40% protection when administered to chicks 2 weeks prior to challenge with A. fumigatus spores. It is recommended that levels of A. fumigatus spores should not rise to 5.8x107.4 cfu g-1 lung tissue in poultry houses. Adjuvants can be added to the vaccine to raise the level of protection using different routes of administration and vaccinating at an older age.

Research Journal of Animal Sciences , 2012, DOI: 10.3923/rjnasci.2012.76.78
Abstract: The study was conducted to determine the occurrence of Aspergilllus species among apparently healthy birds in poultry farms. Trachea swabs were collected from a total of 1500 birds in 52 commercial (10% of birds in each poultry farm visited) poultry farms were sampled. Aspergillus sp. was isolated from 718 (47.87%) of the birds. Six species of Aspergillus were isolated viz: A. fumigatus made up 52.37% (376) of the Aspergillus isolates followed by A. flavus 21.87% (157), A. niger 11.42% (82), A. terreus 8.64% (62), A. restrictus 2.79% (20) and A. ochraceous 2.92% (21). Aspergillus species were isolated throughout the year though with a higher incidence during the rainy season compared to the dry season.

International Journal of Animal and Veterinary Advances , 2011,
Abstract: The aim of this review is to highlight the inadequacies of the current control of African Trypanosomiasis in Nigeria and the need to strengthen the already integrated control approach. African Trypanosomiasis is one of the most devastating diseases of man and animals in Sub-Saharan African countries, Nigeria inclusive. Over the past century numerous methods of control have been developed yet the disease has proved very difficult to eradicate. Current methods to control the disease, in the absence of a vaccine, rely on the use of anti-trypanosomal drugs and vector control. In animals, an additional control method is the use of trypanotolerant breeds of livestock. Unfortunately, all of these methods have disadvantages and none has proved to be ideal. The public health importance of trypanosomiasis, has led to attempts to control the disease nationally and regionally with initiatives such as the Pan African Tsetse and Trypanosomosis Eradication Campaign (PATTEC) of the African union. At the Nigerian Institute for Trypanosomiasis Research (NITR), a combination of control methods is being used for research development and control efforts against the disease. However, diminishing funding for research development and control activities against the disease has hindered this approach. Hence there is a great need to strengthen these integrated approaches for more effective control of trypanosomiasis. Strengthening intersectoral and inter-agency collaboration is greatly advocated in the fight against trypanosomiasis, in order to improve the effectiveness and efficiency of control, as well as enhance the prospect of sustainability and food security as supported by PATTEC. Hence, further fostering the existing relationship with PATEC in a bid towards the eradication of trypanosomiasis from Nigeria.
