RESPONSE OF WEANER RABBITS TO GRADED LEVEL OF OFFAL BASED DIETS OF TIGER NUT (Cyperus esculentus)
Get PDFTwenty crosses of Californian x New Zealand breed of weaner rabbits averaging 4 to 6 weeks old of mix sexes were used to investigate the growth and haematological traits of rabbits fed on tiger nut offal (TNO) based diets ina 35- day experiment. They were randomly allotted to 5 treatment groups and replicated 4 times. Each replicate had 1 rabbit that was housed individually in a cage and were fed twice daily (7.00am and 4.00pm) and had access to drinking water at all times. Feeding troughs and drinkers were provided in each cage and a known quantity of feed was supplied daily. Five diets were compounded to be iso-nitrogenous (18% CP) and iso-caloric (2700 ME kcal/kg) and TNO was included in the diets at 0, 5, 10, 15 and 20%, respectively. Growth was observed and measured in the course of the feeding trial and the results showed non-significance (P>0.05) in feed intake (68.11-75.66 g/rabbit/day), body weight gain (5.39-8.40 g/rabbit/day), feed conversion ratio (6.64-7.82) and proteinefficiency ratio (11.59-13.38); other parameter included feed cost per kg and mortality. Blood samples from rabbit treatments revealed that there was no variation (P>0.05) in packed cells volume (26.25-34.00 %), haemoglobin (9.30-10.10 g/dl), red blood cells (2.23-2.93 X1012) and white blood cells (6.00-7.75 X107). Mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, neutrophils and leucocytes were also not affected by the graded levels of TNO. Serum biochemistry analyses also showed that there was no variation (P>0.05) in the serum glucose (3.65-5.75 mol/l), cholesterol (2.80-5.00 mmol/l), total protein (48.50-52.50 g/dl), albumin (24.00-43.50 g/dl), creatinine (44.50-66.00 μ/l) and triglyceraldehyde (0.25-0.80 mmol/l). Similarly, serum enzymes, alkaline phosphatase, aspartate transaminase and alanine transaminase were not affected (P>0.05) by the inclusion of TNO in the diets. All the electrolytes analyzed, phosphate, calcium, sodium, chloride and bicarbonate were not influenced (P>0.05) by the treatments. The inclusion of TNO in the diet of rabbits did not affect their health status, nutrient bioavailability, and utilization as well as growth rate therefore; farmers can incorporate up to 20% of TNO in the diets of rabbits without causing any deleterious effect
STRUCTURAL AND OPTOELECTRONIC PROPERTIES OF ZnS NANOPARTICLES EXPOSED TO ORGANIC AND INORGANIC CAPPING AGENTS
Get PDFZnS nanoparticles capped with Sodium Carboxyl-methyl Cellulose (CMC-organic) and Tetraethylorthosilicate (TEOS-inorganic) as capping agents were synthesized by chemical co-precipitation and sol-gel technique respectively. Structural, morphological and optical studies of the synthesizes nanoparticles were carried out using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), UV-Vis spectroscopy and Fourier transforms infrared spectroscopy (FTIR). Studies of the capped ZnS nanoparticles revealed zinc blende structure.Particle sizes calculated from Williamson-Hall (W-H) analysis of Uniform Deformation Model (UDM) were (ZnS:CMC) and (ZnS:SiO ). The average strain values calculated from the model indicated that ZnS:SiO has while ZnS:CMC has All samples had smooth surfaces due topassivation of the capping agents. Optical absorption studies shows a blue shift of the absorption edge with bandgap values of and for ZnS:CMC and ZnS:SiO which are higher than the bulk value of ZnS nanoparticles due to quantum confinement effect. The vibrational modes associated with OH-stretching at and the carboxylic group –COOH at confirms the presence of capping agent from the Fourier transform infrared spectroscopy measurement

Get PDFContamination is becoming a threat to spring water in Nigeria especially the Obudu Cattle Ranch spring. This ground water resource is the major source of potable water for both the inhabitants and the agrarian society of the community. This work is part of continuous appraisal of Obudu Cattle Ranchspring. This is to identify the extent of possible contamination and infer the potability of the water. Routine analysis was conducted on the spring water samples to check for the physical, chemical and bacteriological constituents which include the pH, temperature, turbidity, conductivity, alkalinity, magnesium and others. Therefore, the geochemical status of Obudu Cattle Ranch spring in Calabar was assessed for a period of nine years at the peak period of the dry season (in March); using atomic absorption spectrometry (AAS). The result obtained show that, the pH value ranges from 5.7 to 7.3 signifying slightly acidic to neutral water. 
Step-Index Plastic Optical Fibre (SI-POF) Channel Optimisation: M-PAM and Equalization
Get PDFStep-Index Plastic Optical Fibre (SI-POF) is gaining popularity in local area network installations due to its characteristics as an inexpensive medium. This research optimized SI-POF channel of two distances (30metres and 60metres) by introduction of equalizer(s) at the output channel signal with M-PAM (PAM-2 and PAM-4) modulation scheme to address bandwidth limitation and inter symbol interference (ISI). The study which was carried out in MATLAB R2019a environment, study employed decision feedback equalizer-DFE (2, 1), (4, 2) and linear equalizer-LE (2, 0) algorithms to train the output channel signal. The study adopted scatter plots, bit error rate (BER) and data rate (DR) as indices to improve the performance of the output signal.
