ABSTRACT A mathematical model describing the dynamics of Nitrogen transformation and removal in a maturation Waste Stabilization Pond (MWSP) system receiving industrial wastewater was developed. Simulation of the processes was done using STELLA 8_1®, based on the principle of conservation of mass. Besides, measurement of different parameters input to the model was made. Model simulation and mass balance analysis results show that nitrification was responsible for the majority of nitrogen tr...
ABSTRACT The objective of this study was to investigate the effects of planes of nutrition on body weight, haematology and immune responses in broiler chickens vaccinated with NDV I-2 and Lasota vaccines. Two hundred (200) day old broiler chicks of Anak 2000 strain were used for the study. They were randomly assigned into nine groups of 20 birds each. Three feed types (A, B, C) were compounded for the study. Proximate analyses of the feeds were carried out. The groupings are A1 (feed A + ...
ABSTRACT Background: Health belief theory was developed to assess health behavior of individual through examination of perceptions someone may have towards disease and negative outcomes of certain actions. In relation to vaccine uptake, the theory explains why caregivers reject or accept child disease prevention intervention. Methods: Across sectional study design community based was conducted. Purposively sampling method was used to select region and District based on low uptake of Pneumo...
Abstract The effects of varied oral doses of trimethoprim-sulfamethoxazole therapy on the thyroid glands, haematology, serum chemistry and sperm count were evaluated in Nigerian local dogs. Twenty adult male dogs weighing between 4.5-10 kg were used for the study. The dogs were housed in metal cages in the Animal house of Department of Veterinary Parasitology and Entomology, University of Nigeria, Nsukka. The dogs were acclimatized for three weeks during which period they were vaccinated agai...
ABSTRACT Fifteen female grasscutters, obtained from David Mark Farms, Otukpo, Benue State, Nigeria, were used for the study. They were randomly assigned to 3 groups of 5 each according to their ages; 1-3 months, 4-6 months and 7-9 months. They were acclimatized for 14 days. The live weights of the grasscutters were obtained. They were then euthanized with gaseous chloroform in an air-tight container. The female reproductive system (ovaries, uterine tubes, uterine horns, uterus duplex, cervi...
The ARISE Network Adolescent Health Study is an exploratory, community-based survey of 8075 adolescents aged 10–19 in 9 communities in 7 countries: Burkina Faso, Eswatini, Ethiopia, Ghana, Nigeria, Tanzania and Uganda. Communities were selected opportunistically and existing population cohorts maintained by health and demographic surveillance systems (HDSSs). The study is intended to serve as a first round of data collection for African adolescent cohorts, with the overarching goal of gener...
ABSTRACT This study was aimed at determining the prevalence of and awareness of health risks associated with antimicrobial residues (AMRs) in edible tissues of cattle and pigs slaughtered for human consumption in Enugu State. In the first phase, the awareness of public health problems associated with consumption of animal tissues containing AMRs and compliance to specified withdrawal period (WP) by livestock farmers and veterinary practitioners were determined. This was carried out using a ...
Abstract The objectives of this study were to evaluate the factors limiting turkey production in Enugu State, Nigeria, determine the seroprevalence of Newcastle disease (ND) virus infection in turkeys raised in Enugu State and compare the clinical signs and lesions of velogenic ND virus (NDV) in turkeys and chickens. The study consisted of a cross-sectional survey of turkey producers in the three senatorial zones of Enugu State and experimental infection of chickens and turkeys with a veloge...
Abstract The physiological, biochemical and anaesthetic effects of the drug combinations were studies in West African Dwarf goat. In protocol I, there was a significant (p < 0.05) increase in the HR of GP I goats at 10 mins post-induction (PI), which significantly (p < 0.05) decreased from 30 min PI. The HR significantly decreased (p < 0.05) at 20 min in GP IV goats, and at 10 min GP II goats, and returned to the pre-anaesthetic value at 40 min PI. However, HR decreased significantly (p < 0...
ABSTRACT The large-scale use of agrochemicals has raised environmental and human health concerns. A comprehensive intervention strategy for improving agro-chemical safety among rice farmers in Izzi Local Government Area of Ebony State which comprises six communities (Agbja, Ndiebor, Ezza-Inyimegu, Ibeagu, Mgba-ukwu and Ndieze) is lacking. This study is carried out in light of the crucial importance of rice in the attainment of food security status. The study was designed to (i) assess the di...
ABSTRACT Two protocols were used to investigate and compare the biocompatibility of the nonconventional suture material-Cotton Hair Thread (CHT) with conventional silk suture on experimentally induced wounds on rabbits. The results of the study in protocol I showed no significant difference(p > 0.05) in the means of, collagenization, vascularisation, reepithelialization, fibroblasts formation, polymorphonuclear leucocytes (PMNLs) and macrophage proliferation in groups A and B throughout the ...
ABSTRACT This study investigated the effects of different tissue closure techniques and omentopexy in incisional wound healing in West African Dwarf (WAD) goats. Twenty-five male WAD goats aged 6 – 8 months were used for this study. The mean anaesthetic induction, analgesic and surgery time (omentopexy) were: 2.71 ± 0.31, 25.96 ± 1.01 and 58.41 ± 3.20 minutes respectively for all the groups. Serosanguinous exudates were observed at the incision sites between PSD 1 – 8 in GPs A and D a...
ABSTRACT seroprevalence study of Brucella abortus antibodies was carried out in cattle and humans in Taraba State. The aim of the study was to determine the current status of B.abortus in cattle and humans and to find the distribution of the infection with respect to settled and nomadic herds, sex, breed, live and slaughtered cattle, geographical zones and occupation Two LGAs were randomly selected from each of the three senatorial zones totalling six LGAs. In each of the LGAs, 5 herds of ca...
Abstract : Escherichia coli O157 and Salmonella spp. are major food borne pathogens and the emergence of these pathogens has been reported in many countries. The objectives of this study were to examine the meat contact surfaces in Nsukka slaughterhouse and meat sales environment for E. coli O157 and Salmonella species, determine the enterotoxigenic potential and antibacterial resistance profile of the isolated bacteria. For this study, a total of 448 swab samples randomly collected from slau...
ABSTRACT Ten plant samples were screened for topical anti-inflammatory activity. PDI.ra/n hi~w,u leaf (Family: Commelinaceae) gave the highest activity.
