Determination of serum chloride ion concentration in pregnant women from Minjibir local government area, Kano State Nigeria

Serum chloride ion level in blood samples of pregnant women attending ante-natal care clinic in Minjibir was investigated. The mean and standard deviation of the ion in the samples is 100.51± 4.89mmol/L. The distribution is skewed towards high frequency of low concentrations and could be attributed to electrolyte disturbance in some of these women. This disturbance may be due to vomitting, low fluid intake, drugs and malnutrition.Keywords: Chloride ion, pregnant women, ante-nata

Utilization of Neem Leaf Meal: Effect on growth response, haematology and serum biochemistry of rabbit does

This study determined the effect of Neem Leaf Meal (NLM) based - diets on growth response, haematological and serum biochemical indices of female rabbits (does). Twenty four (24) weaned rabbits (5 - 6 weeks old with average body weight of 600 ±1.05g) were used. The NLM was included in the diets at 0, 5, 10, and 15% levels as treatments TI , T2, T3, and T4, respectively. The rabbits were divided into four groups of six (6) each and randomly assigned to experimental diets using a Completely Randomized Design (CRD). Water was provided ad libitum and the rabbits were housed in disinfected wooden hutches for 56 days. Data on growth response, haematological and serum biochemical indices were collected and analysed using analysis of variance (ANOVA). Results revealed that the growth performance parameters showed significant (P<0.05) differences between dietary treatments with progressive decrease in values as the levels of NLM inclusion increased across the diets. The final weight gain ranged between 860 and 970 g/rabbit. The total weight gain was between 310 and 380 g/rabbit, total feed intake ranged between 2150 and 2221 g/rabbit while FCR ranged between 5.84 and 6.94. Growth parameters beyond 10% inclusion level were least compared with values in the control diet. The haematological indices showed that all parameters were significantly (P<0.05) affected by dietary treatments and within the normal ranges for apparently healthy rabbits. The serum biochemical indices were within normal ranges but not significantly affected (P>0.05) by dietary treatments. The study concluded that 10% NLM can be included in the diets meant for rabbits without fear of compromising growth performance and blood characteristics.Key words: Neem, female rabbit, growth, blood indice

Modification and Performance Evaluation of Active Solar Dryer for High Moisture Tomato Crop

In this study, two active solar cabinet dryers with capacity each to dry 10 kg of fresh vegetable were fabricated. The drying cabinet of the first dryer was fabricated using plywood and is refer to as unmodified dryer (UM) while the second dryer with white transparent glass and is refer to as modified dryer (MD). The performances of the two dryers in terms of total drying time, final moisture content obtained and preservation of nutritive values of the dried vegetable were investigated using tomato as sample. Ten kilogram of the sample were sliced to about 1cm and neatly arranged in the drying chamber for the drying process in a period of two days (8am-6pm). The results revealed that there was a reduction in total drying time of 2.5 hours, from 18 hours in UM to 15.5hours in MD which corresponds to reduction in moisture content (wet basis) from initial value of 92% to final moisture content of 12- 13.3%. The results further revealed that maximum drying rate of 6.9 kg/h was observed for UM dryer and 9.4 kg/h for MD both obtained within 8 hours of drying time.  The average temperature recorded in the MD was found more than the UM by about 13°C at 3.00pm. The efficiency of the MD in terms of reduction in total drying time was 13.89% higher than the UM. Proximate analysis result shows the composition of the dried tomato in the UM to be protein, 0.76%; lipids, 1.00%; vitamin E, 0.0083%; moisture content, 13.3%; ash, 0.60% and crude fiber, 1.80%. However, the composition of dried tomato in MD were protein, 0.69%; lipids, 0.90%; vitamin E, 0.0080%; moisture content, 12%; ash, 0.58% and crude fiber, 1.78%

Production and Economics Evaluation of Pilot Scale Essential Oil Extract from Eucalyptus Citriodora Leaves

In this study, essential oil was extracted from eucalyptus citriodora leaves plant species (lemon-scented gum) in a pilot plant using steam distillation technology. The extraction pattern of the oil was monitored over time and economic analysis of the production was carried out.  Five batches were carried out in a day and the results revealed that the daily production of the oil was 0.579 liters in a loading capacity of 100kg of leaves. It was also observed that the total production cycle per batch was 1.96 hours out of which 80 minutes were the actual extraction time with lag period of 37 minutes. The results further revealed that 66.7% of the oil was extracted in 40 minutes while 95.6% in 80 minutes. Liquefied petroleum gas (LPG) was used as source of energy with daily consumption of 7.5 kg at a cost of N2,400.00K. The economic analysis on annual basis revealed that the operating cost was N1,742,400.00K. The production output of the oil was estimated at 138.96 litres with expected selling price of N4,863,600.00K at the rate of N35,000.00K per litre and expected profit after tax of N2,115,871.00K. From this economic analysis carried out based on the practical data generated in the pilot plant, this project is highly profitable and is strongly recommended to potential investors and entrepreneurs. This will help in providing jobs for our teaming unemployed youths mostly in rural areas where these raw materials are in abundant thereby increasing nation’s foreign earning due to its export potential

Footprints of swine influenza H1N1 and H3N2 in pigs from southern Kaduna, Nigeria

Influenza A virus presents a significant public health burden worldwide, with the 1918 Spanish flu pandemic being the most dramatic example. Swine influenza viruses can be transmitted to humans through occupational exposures and in live pig markets. Novel variants can emerge in pigs because they can be infected by human, avian and swine strains. This study was carried out to determine the seroprevalence and serotypes of swine influenza in pigs from a major slaughter slab in southern Kaduna. Using competitive ELISA and haemagglutination-inhibition (HI) assays, 305 swine sera were analysed. The result showed an overall seroprevalence of 28.20% (n=86), with H3N2 7.87% (n=24) emerging as the most dominant subtype in circulation. Concurrent antibody detection of H1N1 in 5.26% (n=16) was also detected in boar 2.62% (n=8) and sows 2.62% (n=8). This study revealed swine Influenza H1N1 and H3N2 serotypes are in circulation in pigs in Kaduna State, and that reassortment in the instance of co-infection of swine host is possible

Seed Needs Assessment in Northeastern Nigeria

Harnessing the genetic potential inherent in crops for higher yields requires the supporting role of all inputs (Manjunatha et al., 2015), of which, quality seed is the most important. In many countries in Sub-Saharan Africa (SSA), a recurrent conflict has become a major factor distorting the availability of quality seeds and the seed system; this has since been the case in northeastern Nigeria. Farmers need quality seeds and planting materials of preferred crops to enable them resume agricultural activities after conflicts. Similarly, seed security is an important component of overall resilience in risk prone environments (FAO, 2016). This study was set-out to analyze existing seed systems in Borno, Adamawa and Yobe States of Northern Nigeria in order to identify practical ways of improving farmer’s access to quality seed

Mechanical Properties and Morphological Characterization of PLA/Chitosan/Epoxidized Natural Rubber Composites

Poly (lactic acid) (PLA)/chitosan (CS) natural polymer/epoxidised natural rubber (ENR) composites were successfully prepared through a solution casting method. The morphological characteristics of fabricated composites were investigated by scanning electron microscopy (SEM) and optical microscopy. The microstructure of PLA/ENR was significantly altered with the addition of CS. SEM analysis of composites fractured surfaces revealed smooth and homogeneous texture and good dispersion of CS. However for 15 wt% CS composites, the phase segregation and poor adhesion between the polymers were observed. Fourier transform infrared spectroscopy revealed some levels of attractive interaction between CS, PLA, and ENR in the composites. The mechanical properties of composites in terms of tensile strength and tensile modulus were significantly improved with the addition of CS into the matrix while the percent elongation at break decreased. The tensile strength increased up to 5 wt% CS loading for both PLA/CS and PLA/ENR/CS and thereafter decreased while Young’s modulus increased up to 10 wt%. However, when the CS content was increased to 15 wt%, the tensile strength and tensile modulus were slightly decreased. These improvements were attributed to good dispersion of CS at the optimum filler levels and attractive interaction between the composites components.</jats:p

Genetic variability and heritability of some selected of cowpea (Vigna unguiculata (L) Walp) lines

The success of most crop improvement programs largely depends upon the genetic variability and the heritability of desirable traits. The magnitude and type of genetic variability help the breeder to determine the selection criteria and breeding schemes to be used for improvement purposes. Two different but related experiments, one in 2011 rainy season (August to November) and the second in 2012 dry season (February to May) were carried out at ICRISAT-Kano, Nigeria screen house to estimate the genetic variability and heritability of some traits in selected cowpea lines. Results of the study showed that there were considerable variations among the lines for duration of vegetative and reproductive phase and for yield characters (seed/pod, number of pod/plant, weight of pod/plant, and 100 seed weight). Broad sense heritability estimate (h2) was 83% for 100 seed weight, 53% for Number of seed per pod, 48% for days to first flower and 46% for number of root nodules. This information showed that there is sufficient genetic variability to justify selection for improvement in the cowpea. This result will be of immense practical uses for plant breeders to choose parent of interest to meet different breeding objectives
