Access to clean and stable electricity is essential in actualizing Nigeria's quest for joining the league of twenty most industrious nations by the year 2020 (vision 20:2020). No country can develop and sustain it development without having a minimum access to electricity for it larger percentage of its population. At present, Nigeria depends petroleum reserves and its aged hydro plant instalments for electricity generation to feed the 40% of its total population that are connected to the national grid. This paper summarizes literature on the current energy issues in Nigeria and introduces the difficulty of the issues involved. The paper also analyses the current (2010) electricity generation as well as the future expansion plans of the Government in 20 years period. The plan includes the introduction of new electrify generation technologies that have not been in used in the base year (2010). The electricity generation system of (including the future expansion plan) was simulated using the LEAP System (Long-range Energy Alternative and Planning). We also investigated the potential environmental impact of siting a nuclear power plant in one of the potential sites based on the site's specific micro-meteorology (land use) and meteorology using the US EPA (Environmental Protection Agency) models; AERMOD 12345. © 2013 Elsevier Ltd.

A study was carried out using 520 household across three states of Benue, Nasarawa and Plateau to characterize goat production and breeding objective traits in north- central Nigeria. Data was collected through participatory rural appraisal (PRA) method, structured questionnaire and interviews were used to determine the productivity of local goats, breeding traits preference and factors used to decide which goat to keep in communal production system. Results obtained indicated that West African Dwarf goat was the main goat breed reared in this zone. Mating was natural and uncontrolled. Herd sizes recorded were 8.48±1.20, 11.71±0.61 and 7.12±1.11 while litter size was 1.6±0.01, 1.4±0.03 and 1.2±0.02 for Benue, Nasarawa and Plateau States respectively. Fast growth, disease resistance, temperament and mothering ability were ranked as the very important attributes in all the communities. Coat colour and body conformation were reported to be of little value as preference traits. The goats have the potential to produce good litter size and attain lower weaning mortality. The communal smallholder goat keeper in this zone selects their breeding stocks based on some adaptive traits such as disease resistance, and also on inherent traits such as temperament, mothering ability and fast growth rate. Inbreeding rate estimated using standard procedure, among the population was low and indication that the goat population at this region is not at risk. It can be concluded that the breeding strategy for the goat is similar in this region. The findings in this study can be used to design an appropriate programme for improvement and conservation of this indigenous goat. © 2016, Fundacion CIPAV. All Rights Reserved.


Sexual dimorphism was examined in 221 randomly selected adult African Muscovy ducks extensively reared in north central Nigeria using univariate and multivariate measures of body size and skeletal proportions. The body parameters investigated included body weight, 8 primary linear body measurements [breast circumference (BTC), thigh circumference (THC), body length (BDL), bill length (BLL), neck length (NKL),foot length (FTL), total leg length (TLL) and wing length (WNL)] and 4 morphological indices (massiveness, stockiness, long-leggedness and condition index). The univariate analysis showed male dominance (p<0.05) in all the morphometric measurements, with the exception of stockiness and longleggedness where significantly higher mean values were recorded for females. Low, moderate and high positive and negative correlations among the body size and shape characters of the ducks were recorded. The canonical discriminant analysis on body weight and primary linear body measurements revealed that wing length was the most discriminating variable between the sexes, followed by body weight, neck circumference, total leg length, body length and foot length respectively. Three other variables not qualified to enter the model were expunged. The single discriminant function obtained (D= -3.116 + 0.280WNL+ 0.921BWT + 0.191NKL - 0.196TLL - 0.063BDL - 0.283FTL) correctly classified 91.4% of individuals of known-sex ducks. This might aid in ecological studies, conservation and improvement of the indigenous ducks.

Natural aquatic plants population can be healthy for any aquatic ecosystems as they serve as fish feed, play an important role in nutrient cycling, purify the water, control unwanted algal growth and support fauna including birds. Water hyacinths (Eichhornia crassipes) have proven to be a persistent and expensive aquatic weed problem. The review was carried out in the face of current global challenge (climate change) which threatens biodiversity conservation and sustainable use of natural resources so that water hyacinth could be viewed as an asset of multifarious benefits considering the revealed highlights rather than been labeled expensive nuisance. The simplest method of management of aquatic weeds is to harvest it and utilize it for cost effectiveness in production such preparation of fish and livestock feeds, bio-gas production, making of charcoal briquetting and waste water treatment for domestic and industrial use. The main problem of utilization and management of water hyacinth is its high cost of transportation to sites for utilization but once this can be overcome as revealed in the review appropriate utilization techniques is recommended. © 2013 Academic Journals Inc.

The changes that have taken place in Nigerian fisheries are reviewed, with the major contributor to fish production in the Nigerian fishery sector which is the Artisanal fishery. From data accumulated over the years by Nigerian Institute for Oceanography and Marine Research (NIOMR) on fishery resources in our coastal waters, fish and shrimps are being over exploited that they no longer sustain the number of registered vessels. Consequently, the potential or maximum sustainable yields must be thoroughly examined on regular basis via sufficient data to determine the status of the fisheries resources and embark on necessary actions that ensure its sustain ab ility. The important ability of fisheries statistics for sustainable fisheries management and under-explored potential of Nigerian waters is also highlighted. The need for human resources development (fisheries statisticians) at each national level was also enumerated and it was identified to operate at regional levels through government funding for joint effective participation. The need to adopt and develop strategie s/technologies that ease addressing the present and uncertainties about future positions of our fisheries was emphasized. The advantages resulting for fisheries sciences are examined and illustrated with examples and the understanding of some alleged weaknesses in some popular concepts and theories would enhance technology adoption with adaptation in making explicit inferences and decisions for the sustainable management of both the present and future situation of our fisheries resources. © 2011 Academic Journals Inc.

Radiation Measurements | Year: 2015

The residents of the world's high background natural radiation areas (HBNRAs), such as Ramsar (in Iran), Guarapari (in Brazil), Orissa and Kerala (in India) and Yangjiang (in China) have lived in these areas for generations under extraordinary radiation fields. The failure of earlier epidemiological studies to report any substantial increase in cancer incidence in HBNRAs has raised some controversy regarding the validity of the linear no-threshold hypothesis. This paper reviews some of the most recent studies of HBNRAs with the intent of stimulating greater research interest in the dosimetric, epidemiological and radiobiological issues related to the world's HBNRAs and proposes solutions to the challenges facing HBNRA studies. This paper may serve as a useful reference for some of the harder-to-find literature. ©2015 Elsevier Ltd. All rights reserved.

Body weight and nine morphostructural characters (withers height, rump height, heart girth, body length, head width, cannon circumference, shoulder width, rump width and rump length) of 83 White Fulani cows aged 1.5-2.4 years old were used to study the problem of multicollinearity instability in the estimation of body weight from morphological indices. Pairwise phenotypic correlations indicated a high and positive significant relationship between body weight and body dimensions (r = 0.61-0.94; P<0.01). Among the linear type traits, the highest correlation was observed between withers height and rump height (r =0.98) while the lowest value was recorded for rump height and shoulder width (r =0.51). Severe collinearity problems were evident in 5 of the zoometrical variables as portrayed by variance inflation factors (VIFs) higher than 10.00 (VIF = 33.096, 31.421, 24.612, 22.726 and 13.327 for rump height, withers height, rump length, heart girth and body length respectively). Collinearity problems were further confirmed from the computations of the eigenvalues of the correlation matrix, condition indexes and variance proportions. Heart girth was retained among the collinear variables, and singly accounted for 87.9%, 92.3% and 94.1% of the variation in body weight in the subsequent stepwise regression, quadratic and cubic models, respectively.

Breeding performance of Clarias gariepinus under different dietary crude protein (CP) levels 30%, 35%, 40% and a broodstock diet (imported feed) as the control. Female broodstocks were subsequently induced for breeding and were stripped after 11 hours latency period. Weight of eggs stripped increased with increase in dietary protein levels and no broodstock mortality was recorded. Hatchability rate was highest in fish fed 40% C.P (90.33± 0.44%) which was only marginally different from fish fed 35% CP (89.42± 0.01%) while fish fed 30% CP diet had the least hatchability rate (84.70± 0.12%). Advanced frys were monitored for 3 weeks under intensive feeding and frys from fish fed 40% CP dietary level had superior mean weight gain, specific growth rate, feed conversion ratio and protein efficiency ratio indicating sufficient level of nutrient for gonad development while fry from fish fed 35% CP diet only had marginally different specific growth rate compared with the former (p>0.05). This study revealed that dietary protein level at 35% CP was able to ensure fish growth maintenance, while 40% CP diet sustained the fish further to ensure proper gonadal development and maturation and consequently, superior performance of the hatchlings.

This study was carried out for 21 days to determine the impact of treating peanut (Arachis hypogea) husk, an economically important cash crop in Nigeria with white rot fungi: Pleurotus ostreatus and Pleurotus pulmonarius, and the resulting impact on the chemical composition and in vitro digestibility. Solid state fermentation improved the crude protein (CP) from 7.39% (control, UM) to 9.29% for Pleurotus ostreatus (POT) and 16.10% for Pleurotus pulmonarius (PPT). On the contrary, fungal treatment depleted the crude fiber (CF) from 26.2% in UM to 16.9% for POT and 18.7% for PPT. In a similar trend, the fungal treatment increased significantly (p<0.05) the neutral detergent fiber and acid detergent fiber. Wide variations were also observed in the mineral contents of the substrates under study with higher value obtained in all the major minerals with the exception of sodium. However, copper (Cu) was observed to be higher in the treated substrates compared with the untreated. Fungal treatment increased the iron (Fe) content of POT. The fermentation of the insoluble fraction (b) increased consistently from 34.33mL in the control to 50.67mL for POT and 53.33mL. Faster rates of gas production were also observed in the treated peanut husk compared with the untreated. Gas volume was significantly higher at all incubation period in the fungal treated substrates. The estimated metabolisable energy (ME), organic matter digestibility (OMD) and short chain fatty acid (SCFA) also increased with fungal treatment. The results of this study indicate that fungal treatment of peanut husk have the potential to be used as feed supplements for ruminants especially during the dry season when feedstuffs are lacking and the only available feedstuffs are crop residues.

Research results and facts about indigenous Muscovy duck production in Nigeria are reviewed with the aim of assessing its current status and delivering relevant information to stakeholders and other potential beneficiaries. There are large variations in phenotypic and biochemical characteristics of indigenous Muscovy ducks in the country, which could serve as a basis for genetic improvement. These ducks have the potential for a mean live weight of 2.73 and 1.52 kg and dressing percentage of 71.2% and 69.8% for drakes and ducks, respectively. Under scavenging, backyard farming conditions, the ducks can lay between 60 and 80 eggs each per year, and about 100 and 125 eggs per bird per year with an egg weight of about 72g under improved management conditions. The morphological, meat and egg attributes of local Muscovy ducks may be exploited in management decisions geared towards ensuring an increase in productivity, thereby making an important contribution to food security in a developing economy.
