Geospatial Approach to Solving Traffic Congestion Problems In Mushin Local Government Area of Lagos State

The variation in road conditions in relation to traffic congestion overtime enhances the need for proper development of a geospatial platform by comprehensively building and relating the attributes information of the entire road network with respect to various road segments. This is better executed through the concept of dynamic road segmentation. The aim of this study is to carry out geospatial data structure of dynamic road segmentation in Mushin local government area of Lagos State showing the road segment (spatial data) and its topological information.The selected roads within Mushin Local Government were extracted from a street map of Mushin Local Government Area gotten from the office of the Surveyor General of Lagos state. The selected roads were digitized to obtain the spatial information required for the road segmentation. The road vectorization or digitization was carried out in ArcGIS 10.2 software. It was created as a separate shapefile and added as a layer within the GIS environment.The information acquired from the field survey describing the road network as well as the segments i.e. the attribute information, formed a database developed in a GIS platform using ArcGIS 10.2 software. This relational database contains information such as name of road, segment ID, nature of roads, nature of segments, presence of pot holes, presence of crime scenes, presence of congestion, causes of congestion, local inhabitants of segment, length of segments, adjoining land use (to the left and right), mode of transportation along the segment, the traffic condition of the roads and the number of lanes of the road.These large amount of attribute information for all the segment were geospatially referenced with respect to the positions of all the segments and this is the basis of every GIS operation; providing an environment for relating the spatial locations of features with the attribute information describing the spatial feature (which in this case the roads and the road segments represents the spatial feature)Spatial query by attribute as well as location can easily be carried out to select road segments of interest based on predefined criteria using a specific Structural Query Language (SQL) within the GIS environment.Dynamic road segmentation provides a platform for planning and controlling changes on road network. Since the roads are broken down into segments, temporal changes of the road structure as well as the traffic conditions of the roads can be analysed and suitable decisions as well as policies for proper road maintenance can easily be taken and the policies implemented with respect to the segmentation of the roads. It also aids the security organization implementing platform within a GIS environment to monitor the crime scenes with respect to affected segment and would aid in the deployment of security agents at the appropriate locations in case of emergency.In the control of traffic, dynamic road segmentation aid in deciding the alternative conditions to follow since the entire road network have being spatially segmented and the conditions of all the segments built into the GIS database.

Willingness to use ice-fish box by fresh fish value-chain actors in Lagos State, Nigeria

A fish preservation technology was developed in the year 2016 by Nigerian Stored Products Research Institute, (NSPRI) in a well-insulated container known as “NSPRI Ice-Fish Box” (NSPRI-IFB). The technology was disseminated to fresh fish value-chain actors (farmers, marketers, processors and transporters) in selected coastal local government areas of Lagos State namely Lagos Mainland, Epe, Badagry and Ikorodu which housed Asejere, Epe, Badagry and Ijede fish markets respectively in 2019. The study was conducted in these markets to ascertain the awareness status and determine the willingness of these actors to use NSPRI-IFB. Data were randomly collected from 110 respondents selected through a simple random sampling procedure using questionnaire and analysed using descriptive statistics and Chi-square statistical tool. Excellent numbers of actors (81.82%) are well aware of NSPRI-IFB while 27.27% of them declare they are not aware. Results further shows that actors are very willing to use NSPRI-IFB for fresh fish preservation (x̄ = 3.87) and transportation (x̄ = 3.81). However, they are not at all willing to use the technology for fish processing (x̄ = 1.67) and curing (x̄ = 1.73). Chi-square analysis reveals significant associations (p≤0.05) between willingness to use NSPRI-IFB and actors’ age and level of education. Conclusively, value-chain actors are well aware and are willing to use the technology. Fresh fish postharvest loss reduction policy should be directed towards mass adoption of NSPRI-IFB.

Many (58.6%) had good involvement in antenatal care. Male involvement was statistically significant with age, educational status, occupation and income with p value of 0.004, 0.024, < 0.001and 0.04 respectively.Conclusion: Age, education, occupation and income were significantly associated with male involvement. Young males should be encouraged to pursue formal education and vocational opportunities.

Perceptions and experiences of maternity care workers during COVID-19 pandemic in Lagos State, Nigeria; a qualitative study.

BackgroundThe COVID-19 (coronavirus disease 2019) pandemic challenges provision and access to essential maternity care in low-resilience health systems. The aim of this study was to explore maternity healthcare workers’ experiences of, and perceptions about providing maternity care during the COVID-19 outbreak in Lagos State, Nigeria.MethodsThis qualitative study conducted individual, remote, semi-structured interviews with midwives and traditional birth attendants (TBAs). Eligible participants spoke English, and provided maternity care during COVID-19 in Lagos, Nigeria. Participants were recruited via purposive and snowball sampling, from primary health facilities in seven Local Government Areas of Lagos State. Interview transcripts were analysed thematically following the framework method.ResultsSixteen midwives (n = 11) and TBAs (n = 5) were interviewed from March to April 2021. Two overarching themes were identified from the data. ‘Maternity care workers’ willingness and ability to work during the COVID-19 pandemic’ outlined negative influences (fear and uncertainty, risk of infection, burnout, transport difficulties), and positive influences (professional duty, faith, family and employer support). Suggestions to improve ability to work included adequate protective equipment, training, financial support, and workplace flexibility. ‘Perceived impact of COVID-19 on women’s access and uptake of maternity care’ highlighted reduced access and uptake of antenatal and immunisation services by women. Challenges included overstretched health services, movement and cost barriers, and community fear of health facilities. Participants reported delayed healthcare seeking and unattended home births. Midwives and TBAs identified a need for community outreach to raise awareness for women to safely access maternity services. Participants highlighted the responsibility of the government to improve staff welfare, and to implement public health campaigns.ConclusionsDespite disruption to maternity care access and delivery due to COVID-19, midwives and TBAs in Lagos remained committed to their role in caring for women and babies. Nevertheless, participants highlighted issues of understaffing and mistrust in Lagos’ underfunded maternity care system. Our findings suggest that future resilience during outbreaks depends on equipping maternity care workers with adequate working conditions and training, to rebuild public trust and improve access to maternity care.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12913-022-08009-y.

Groundwater Quality Assessment of Ikorodu Local Government Area of Lagos State in Nigeria

An assessment of the quality of groundwater in Ikorodu Local Government Area (LGA) was carried out in September 2020 (Late wet season). A total number of 29 samples were collected from different selected locations of the study area. The samples were collected from private and government bore holes. The pH, Total dissolved solids (TDS), Salinity, Turbidity, Hardness, Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), Phosphate, Nitrate, Sulphate, and Total bacterial count (TBC) were determined according to American Public Health Association (APHA) standard techniques. The results showed that the mean pH, TDS, Salinity, Turbidity, Hardness, BOD, COD, Phosphate, Nitrate, Sulphate, and TBC in the water samples were 7.0 ±0.59, 176.0 ±132.2mg/L, 0.14 ±0.11g/kg, 0.32 ±0.05 NTU, 59.58 ±34.89mg/L, 11.59 ±3.41mg/L, 14.90 ±4.18mg/L, 0.97 ±0.46mg/L, 2.62 ±1.27mg/L, 9.44 ±5.94mg/L, and 4.92 ±2.94 x 102 cfu/mL, respectively. The calculated Water quality index (WQI) of the different sampling points showed the least WQI was 50.3 and the highest WQI was 66.9. Overall, the WQI indicated “Poor” quality of groundwater in the Ikorodu Local Government Area of Lagos State.

MARKET SURVEY OF ANIMALS COMMONLY USED AS BUSH MEAT IN OLUWO MARKET, EPE IN SOUTHWEST NIGERIA: HOW LONG WILL THERE BE SUSTAINABILITY OF EXPLOITED WILDLIFE SPECIES?

The trade of bush meat in Oluwo Market, Epe at Epe Local Government Area of Lagos State was investigated. Eleven animal species from three different classes (Amphibia, Reptilia and Mammalia) of vertebrates were found to be commonly used as bush meat. Xenopus muelleri (frog) was the most abundant animal species traded in the market followed by Crocidiora sp (shrew) and Cephalophus maxwelli (antelope) each having a weekly sale of about 30 individuals. Bitis sp (viper), Pelusioscasteneus (turtle) and Varanus niloticus (monitor lizard) were the least abundant traded animals with a weekly sale of eight, ten and ten respectively. Pertaining to ethnozoological uses, different parts of animal species were used to cure diseases, appease witches, prevent accidents, protect against evil and seek marital partner. Other traders (34%) were the highest customers of bush meat followed by the consumers (22%) and the hotel and restaurant owners (22%). Students and researchers (8%) were the lowest group of customers patronizing the bushmeat trade. Analysis of Variance showed that there was no significant difference between nutritional contents of the various bush meat species at (df= 3; P< 0.005). Appreciating the importance of bush meat both economically and ethnozoologically, it is not only imperative to emphasize and educate all stakeholders in this trade the importance of its conservation and sustainable use, but to also offer efforts that would provide alternative source of protein. Given the present trend of exploitation, many wildlife species may undergo local extinction if urgent measures are not taken

Family Instability as a Predictor of Academic Performance Among Secondary School Students in Oshodi/Isolo Local Government Area of Lagos State, Nigeria

The research investigated Family instability as a predictor of academic achievement of secondary school students. survey research design of expo- facto type was used for the study. A total of 200 participants were randomly sampled for the study. Data were collected with self-developed family instability questionnaire, while the students’ scores in mathematics and English were used as academic achievement data. The reliability of the instrument was measured through pilot testing and Cronbach’s alpha test was employed to check the consistency and accuracy of the measurement scale. A reliability coefficient of 0.73 was obtained, which indicates that the items in the instrument measured similar concept. Three hypotheses were raised and tested at 0.05 level of significance. The data were analyzed using Pearson product moment statistics method. The result of the analysis showed a significant relationship between family instability and academic achievement of secondary school students (junior, senior). On the basis of the findings it was recommended among others that that couples should avail themselves of the services of marriage counselors in the resolution of marital disputes.

Impact of Research- and Assessment-based Instructional Modes on the Achievement of Senior High School Students in Selected Chemistry Topics

This research focused on the impact of research- and assessment-based instruction on senior high school students’ achievement in selected chemistry topics. A 3 × 2 × 2 pre-test and post-test control group in a quasi-experimental research design was used on a population of Grade 11 chemistry students in Ojo Local Government Area of Lagos state. Two schools (one public and one private) were randomly assigned to each of the treatments. A sample of 240 chemistry students was used. Three research questions were answered and five hypotheses were tested. The reliability coefficient of the “Chemistry achievement test” was found to be 0.770 using the Kuder–Richardson Formula 20. Research-based, assessment-based, and conventional instruction manuals were also developed. The data collected were analyzed using descriptive statistics and analysis of covariance. It was found that the impact of assessment- and research-based instruction on senior high school students’ achievement in the selected topics was significant (F (2,227) = 49.214, p < 0.050). It was also found that the students exposed to the assessment-based instructional mode had a higher achievement than those in the research-based and conventional groups. Male chemistry students were found to benefit more than the female students after being exposed to research- and assessment-based instructional modes. It is, therefore, recommended that assessment- and research-based instructional modes be used to teach the selected chemistry topics to enhance effective learning.

Conclusively, value-chain actors are well aware and are willing to use the technology. Fresh fish postharvest loss reduction policy should be directed towards mass adoption of NSPRI-IFB.

ENVIRONMENTAL POLLUTION: EFFECT ON PEDESTRIANS WHILE WALKING IN URBAN STREET

Purpose: The reason for this study is because of observed difference in environmental condition in Lagos metropolis. The change is witnessed in environmental change arising from air, water and noise pollution mostly from increasing vehicle emissions in the State. This study has been conducted to analyze the environmental effects of pollution on pedestrians. Specific objectives are determine the air quality of the city at most populate headquarters of each of the 20 Local Government Areas of Lagos State, to examine the impact of pollution (air, water and noise) on pedestrians and assess various measures for reducing environmental pollution in the State.
 Methodology: The use of Thermo scientific MIE pDR-1500 instrument was used to measure air quality index of the selected locations and survey was carried out with well-structured questionnaire to elicit information with the aid of incidental sampling technique on impact of pollution on pedestrians from 177 respondents.
 Findings: Air Quality Index was shown with histogram chart where six out of 20 Local Government Areas are above the acceptable standard of pollution. There is rising cases of pollution in the State and very few Local governments were within acceptable range. One –Sample T-test showed that air pollution is majorly affecting pedestrians with t-value of 22.226 followed by noise with 19.643 and water with 5.529 respectively.
 Conclusion and recommendations: The research concluded that, there is need to control the rising cases of pollution in the state and policies to tame air and noise pollution in the state should be adopted. Emission control strategies to be adopted with the existing ones can be in form of restricting hours of movement of vehicles to late at night to avoid human pollutant contact, encourage tree planting and rapid evacuation of environmental waste.

Occupational health hazards and use of personal protective equipment among automobile mechanics in Surulere local government area of Lagos State, Nigeria - a descriptive study

Introduction: The job of an automobile mechanic is associated with hazards, illness, and injuries, which may result in sickness, absenteeism, economic loss, disability, or even death. This study assessed the level of knowledge and workplace safety practice by automobile mechanics.
 Methods: A descriptive cross-sectional study was carried out among 120 registered automobile mechanics in Surulere Local Government Area of Lagos State, Nigeria. A questionnaire was used to obtain information on socio-demography and occupational health practices. Data entry and analysis were done with Epi-info 3.5.1(2008). Chi-square and Fischer Exact tests were used to test for significance.
 Results: The respondents were all males with a mean age of 39.9±7.5 years, the majority learned the trade through apprenticeship (95.80%) and on full-time work (98.30%). Most respondents (95.8%) were aware of at least one health problem associated with its hazards. Over 75% of respondents were aware of physical hazards. Over eighty percent (84.17%) of respondents used their own overalls, 40% of them used overalls regularly, and only 26.67% of respondents used overalls appropriately.
 Conclusion: Many respondents were aware of health problems, occupational hazards, and PPE used in the Automobile workplace but did not translate to good practice of workplace safety as seen in only 1.67%. The respondents did not deem the use of PPE necessary and lack, or inadequate training on the ‘how’ and ‘why’ PPE were identified as factors hindering PPE use. Workers' training and adherence monitoring could help improve good workplace safety practices in Lagos, Nigeria.

Morbidity Pattern, Physiologic Parameters and Outcome among Elderly Patients Attending Selected Primary Healthcare Facilities in an Urban Region of Lagos

Background: In Nigeria, the elderly account for 4.97% of the total population and as one ages, the physiological status of the body gradually declines.Hypertension, cataract, osteoarthritis and neurological problems, constitute the commonest cause of morbidity among elderly. This results in inadequate medical attention leading to development of multiple health conditions and the inability to control certain physiological functions. Objective: This study aimed to describe the morbidity pattern, physiologic parameters and outcome among elderly patients attending the primary healthcare centres in Kosofe Local Government Area of Lagos State, Nigeria. Methods: The study was a descriptive cross-sectional consisting of 210 participants selected through systematic sampling. Data on morbidity pattern, physiologic parameters and disposition decisions were collected and analyzed using Epi-info, version 7.2. Proportions, means and frequencies were calculated and presented with Tables while Chi-square was used to test for association between morbidity and gender, age and outcome, vital signs and age, and disposition decision and sex. P-value < 0.05 was considered statistically significant. Results: Disease such as hypertension (51.4%), malaria (18.5%) and osteoarthritis (6.6%) constituted the major reasons of visit of the elderly to primary healthcare facilities. There were statistically significant associations between cardiovascular condition and gender (p=0.005), and between musculoskeletal condition and age of the respondents (p=0.005). There were statistically significant associations between the urological conditions and outcome of the respondents (p= 0.001), between the pulse and age of the respondents (p=0.001), between respiratory rate and age (p=0.001) and between percentage oxygen saturation of haemoglobin and age (p=0.001). Conclusion: Diseases such as hypertension, osteoarthritis and malaria constitute the major cause of visits to primary healthcare facilities among the elderly. Those with cardiovascular disease were more likely to be females. Those with age range of 75-79 years may likely have a pulse rate less than 60 bpm. Those within the age of 70–74 years are more likely to have a low blood oxygen saturation level. Those with urological condition were more likely to be referred.

Hepatitis B and C seroprevalence among residents in Lagos State, Nigeria: A population-based survey.

Hepatitis is one of the leading causes of morbidity and mortality, particularly in developing countries. It is often caused by hepatitis B and C, which are both preventable and treatable. Available information on Hepatitis B and C in Nigeria is based primarily on estimates obtained from specific population sub-groups or hospital-based surveys leaving gaps in population-level knowledge, attitudes, and prevalence. This study aimed to assess the knowledge, attitude and associated factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections amongst residents of Lagos State. This was a community-based descriptive cross-sectional study carried out in all the 20 local government areas of Lagos state using a multistage sampling technique. Data were collected using pre-tested interviewer-administered questionnaires. Blood samples were taken (pinprick) from respondents (n = 4862) and tested using hepatitis B and C surface antigen tests after obtaining informed consent. The overall prevalence of HBV infection in Lagos State was 2.1% while the prevalence of HCV infection was 0.1%. Only about half of all the respondents (50.9%) had heard about hepatitis B before the survey. Knowledge of the specific symptoms of HBV was also very low. For instance, only 28.1% of the respondents knew that yellowness of the eyes is associated with hepatitis while < 1% (0.1%) knew that HBV infection is associated with the passage of yellow urine. The most common source of information about hepatitis was the radio (13.0%). Only 36.2% of the respondents knew that HBV infection could be prevented. Overall, 28.8% of the respondents were aware of the hepatitis B vaccine. Less than half (40.9%) felt it was necessary to get vaccinated against HBV, however, a similar proportion (41.9%) would want to be vaccinated against HBV. Only 2.5% of all the respondents had ever received HBV vaccines while 3.5% had ever been tested for hepatitis B before this survey. There was a statistically significant association between HBV infection and respondents' use of shared clippers and work exposure involving contact with body parts and body fluids (P < 0.05). The knowledge, awareness and risk perception of HBV infection were low, however, almost half of the residents were willing to receive hepatitis B vaccinations if offered. It is recommended that the population-based prevention programmes and regular community-based surveillance be conducted by the public health department of Lagos State Ministry of Health. In addition, the strengthening of routine immunisation and vaccination of high-risk groups should be prioritised.

Infection Control Practices among Laboratory Healthcare Workers in an Urban Local Government Area of Lagos State, Nigeria

Background: Laboratory healthcare workers do handle a wide range of potentially dangerous materials which exposes them to numerous hazards. This study aimed to assess the practices of laboratory health care workers towards safety, infection control and the associated factors to its practices.&#x0D; Case Presentation: A cross-sectional study was conducted among 181 laboratory healthcare workers in all registered 33 laboratory facilities in Ikeja Local Government Area in 2017. Data were collected with pre-tested, structured self-administered questionnaires. Data analysed with SPSS version 20 and p-value of &lt; 0.05. The mean age of respondents was 35.0 ± 2.45 years, most of whom were females (57.7%) and married (61.1%). The majority (98.9%) demonstrated good knowledge of infection control. A total of 62.3% identified hand washing as the most important infection control practice while HIV and Tuberculosis were diseases respondents majorly considered as high risk of contracting. A total of 84.6% of the respondents showed good practices. Limited availability of personal protective equipment in the laboratories was a major barrier identified by 98.1% of respondents. Respondents displayed good knowledge, attitude and practice of infection control.&#x0D; Discussion and Conclusion: Barrier to infection control was the limited availability of personal protective equipment. Therefore, concerted efforts should be mustered to ensure continuous training and retraining with the provision of personal protective equipment. &#x0D;

Isolation of Cellulase Producing Microorganisms from Sugar Bagasse Dump Sites in Lagos, Nigeria

Introduction: Soil is an important reservoir for a diverse group of microorganisms. However, human activities including disposal of solid wastes affects the quality, composition, and microbial communities in the soil. The polymeric units of compounds in a soil determines the type of microbial activities in the soil. Aim: This work investigated the cellulose-degrading potential of the microbial profile of a sugarcane bagasse dumpsite at Ojo Local Government Area of Lagos State. Materials and Methods: The samples collected from this location were labelled A, B, and C respectively based on the soil depth. The samples were processed and inoculated on Nutrient Agar and Potato Dextrose Agar (PDA), to isolate bacteria and fungi. However, the cellulose-degrading ability of the isolates were determined by subculturing the isolates into Mandel’s medium containing Carboxymethyl cellulose (CMC). Results: The physiochemical analysis of the soil samples revealed the variations in parameters such as pH, moisture, nitrogen, organic carbon etc, at different soil depth. Four cellulose-degrading bacteria and fungi were isolated. The isolated bacterial species are Bacillus species, Serratia species, Pseudomonas species and Lactobacillus species. Bacillus species had the highest cellulose-degrading potential amongst the four isolates with Serratia species having the lowest. The isolated fungal species are Aspergillus niger, Penicillium species, Mucor species, Neurospora species, Microsporium species and Aspergillus flavus. Conclusion: In this work, we demonstrated successfully that soil from sugarcane bagasse dumpsite is a rich source of cellulose and possesses a high rate of activities of cellulolytic bacteria and fungi. The major deduction from this work is that Bacillus species and Mucor species are prominent cellulolytic microorganisms and have immense potential for industrial applications.

Occupational Ocular Injuries and Utilization of Eye Protective Devices among Sawmill Workers in the Ojo Local Government Area of Lagos State, Nigeria.

In this work, we carried out a cross-sectional study to assess occupational ocular injuries and utilization of eye protective devices among sawmill workers in the Ojo local government area of Lagos State, Nigeria A structured questionnaire was used to conduct face-to-face interviews among the sawmill workers. Pearson’s chi-squared test and t-test were used to test associations between variables. A p-value of less than 0.05 was considered statistically significant. A total of 215 sawmill workers with a mean age of 37.08 ± 12.07 years participated in the study. A majority (55.8%) of the participants were male (93.7%), and a majority were 21–40 years old (55.8%). Of the participants, 78.6% were aware of occupational ocular injuries and 17.7% used ocular safety devices. The major barrier to the use of eye protective devices was unavailability (43%). Workers who were ≥20 years old (p < 0.001), who received a monthly salary of less than USD 100 (p < 0.043), who had work experience of ≥10 years (p < 0.04), who were aware of ocular hazards (p < 0.03), and who did not use protective eye devices (p < 0.02) were significantly associated with occupational ocular injuries compared to others. The prevalence of occupational ocular injuries and the utilization of eye safety devices among the sawmill workers in the current study were comparable to findings from other studies. Based on the results of our study, we advise the provision of ocular protective devices for sawmill workers and policies to enforce regular utilization.

Kinetic modelling of dumpsite leachate treatment using Musa sapientum peels as bio-sorbent

Kinetics models are very vital to dumpsite operators and planners as they provide relevant information for effective treatment of leachates. The aim of this work is to model the kinetic process of treatment of Lagos dumpsite leachate using Musa sapientum peels as bio-sorbent with a view of establishing the kinetic parameters of the treatment process. Musa sapientum peels which were collected from Ayetoro market in Epe Local Government area of Lagos State were used to prepare the bio-sorbent. Kinetic process was carried out using 1 g of the prepared bio-sorbent in 100 ml Lagos dumpsite leachate in different conical flasks and at various contacting time. The kinetic data obtained were fitted to different kinetics models. The kinetics models tested were Fractional power model, Lagregren pseudo first – order model, Pseudo second – order model, Kuo – Lotse kinetic model, Blanchard kinetic model and Elovich kinetic model. Other kinetics models considered were Sobkowsk – Czerwi kinetic model, Intraparticle diffusion (IPD) model, Behnajady – Modirshahla – Ghanbery (BMG) model and Diffusion – Chemisorption model. Coefficient of determination (R2) values and the expected nature of the plots of the models were used to screen the tested models. The results revealed that the Pseudo second – order kinetic model has the best R2 value of 0.99996 and the graph followed the expected nature of the plot hence it was adopted in this work. It was concluded that Pseudo second – order kinetic model can be used to navigate the treatment process of Lagos dumpsite using Musa sapientum peels as bio-sorbent.

Blood profile of prevalent sheep breeds in Nigeria: A case study of Ikorodu Local Government Area of Lagos State, Nigeria

The role of the environment in the survivability of an animal is paramount and blood profiles are part of the indices for measuring the health status. Therefore, a study was carried out to determine the blood profile of prominent indigenous breed of sheep (Ram) viz: West African Dwarf, Yankasa, Balami and Ouda breeds reared in Ikorodu Local Government. A total of 20 rams were used comprising of five rams per breed, with average age of 2½ years weighing 31.13±4.8 kg. Blood samples were carefully collected from the rams into labeled sterile bottles containing EDTA for haematological examination and another set of bottles containing Lithium Heparin was used to collect blood for the serum biochemical analysis. Haematological parameter assessed were Packed Cell Volume (PCV), White Blood Cell (WBC), Red Blood Cell (RBC), while the biochemical parameters investigated were Total protein (Tp), Albumin, Glucose, Creatine Cholesterol, and Alkaline phosphatase (ALP). PCV was significantly (p&lt;0.05) highest (32.25%) in Yankassa and lowest (26.25%) in Ouda. Yankasa had statistically (p&lt;0.05) the higher 11.66g/dL Hb, followed by WAD (10.00), Ouda (9.60) and lower (9.20) in Balami. RBC (x10/ml) was significantly (p&lt;0.05) higher in WAD (3.72) than other breeds and lowest in Ouda (3.11). MCV (fl) value was significantly lower in Yankasa (75.83) than other breeds and higher in Ouda (83.60). MCH (pg) was statistically (p&lt;0.05) highest (30.89) in Yankasa and lower (26.93) in Balami. Yankasa had significantly(p&lt;0.05) the higher (8673.00) Total WBC (mm3), followed by WAD (8453.25), Balami (6814.25) and least in Ouda (6718.75). Total protein was significantly (p&lt;0.05) the higher (53.76) in WAD ram and lower (43.76) in Ouda. Yankasa ram recorded significantly (p&lt;0.05) the higher Albumin content (5.45), glucose level (48.87), ALP (129.71) and significantly the least creatine (0.63) while significantly (p&lt;0.05) the least values for Glucose were in Ouda (44.83), Albumin content and Alkaline phosphatase in Balami (4.33, 104.87 respectively). Cholesterol value was significantly the higher (93.22) in WAD and lower (79.70) in Balami. Results revealed significant differences in haematological and serological indices tested though all values obtained were within the normal range for sheep. &#x0D; &#x0D; Le rôle de l'environnement dans la survie d'un animal est primordial et les profils sanguins font partie des indices de mesure de l'état de santé. Par conséquent, une étude a été menée pour déterminer le profil sanguin de la race indigène de moutons (bélier), à savoir: les moutons nains d'Afrique de l'Ouest (WAD), Yankasa, Balami et Ouda élevés dans la collectivité locale d'Ikorodu. Au total, 20 béliers ont été utilisés comprenant cinq béliers par race, avec un âge moyen de 2 ans et demi pesant 31,13 ± 4,8 kg. Des échantillons de sang ont été soigneusement prélevés sur les béliers dans des flacons stériles étiquetés contenant de l'EDTA pour un examen hématologique et un autre ensemble de flacons contenant de l'héparine de lithium a été utilisé pour collecter du sang pour l'analyse biochimique du sérum. Les paramètres hématologiques évalués étaient le volume de cellules emballées (PCV), les globules blancs (WBC), les globules rouges (RBC), tandis que les paramètres biochimiques étudiés étaient la protéine totale (Tp), l'albumine, le glucose, la créatine cholestérol et la phosphatase alcaline (ALP). Le PCV était significativement (p &lt;0,05) le plus élevé (32,25%) à Yankassa et le plus bas (26,25%) à Ouda. Yankasa avait statistiquement (p &lt;0,05) le taux d'Hb le plus élevé de 11,66 g / dL, suivi de WAD (10,00), Ouda (9,60) et moins (9,20) à Balami. Les globules rouges (x10 / ml) étaient significativement (p &lt;0,05) plus élevés chez WAD (3,72) que chez les autres races et plus faibles chez Ouda (3,11). La valeur MCV (fl) était significativement plus faible à Yankasa (75,83) que dans les autres races et plus élevée à Ouda (83,60). MCH (pg) était statistiquement (p &lt;0,05) la plus élevée (30,89) à Yankasa et inférieure (26,93) à Balami. Yankasa avait significativement (p &lt;0,05) le plus élevé (8673,00) WBC total (mm3), suivi des moutons nains d'Afrique de l'Ouest, (8453,25), Balami (6814,25) et inférieur à Ouda (6718,75). La protéine totale était significativement (p &lt;0,05) la plus élevée (53,76) chez les moutons nains d'Afrique de l'Ouest, et la plus faible (43,76) chez Ouda. Le bélier Yankasa a enregistré de manière significative (p &lt;0,05) la plus haute teneur en albumine (5,45), le niveau de glucose (48,87), l'ALP (129,71) et significativement le moins de créatine (0,63) tandis que de manière significative (p &lt;0,05) les valeurs les plus faibles pour le glucose étaient à Ouda (44,83), teneur en albumine et phosphatase alcaline chez Balami (4,33, 104,87 respectivement). La valeur du cholestérol était significativement la plus élevée (93,22) chez les moutons nains d'Afrique de l'Ouest et la plus basse (79,70) chez Balami. Les résultats ont révélé des différences significatives dans les indices hématologiques et sérologiques testés bien que toutes les valeurs obtenues se situent dans la plage normale pour les moutons.
