This study evaluated the response of growing pigs fed diets containing Black Soldier Larval Meal (BSFLM) substituted for Soya Bean Meal (SBM). Twenty-four (24) crossbred (Large white x Landrace) male and female growing pigs with initial average body weight of 18.25kg were used for the study. Pigs were randomly allotted by the use of weight equalization tool (WE Tool) into four treatment groups, each with six replicates. Four experimental diets were formulated such that BSFLM replaced SBM at 0, 10, 20 and 30% levels. Data were collected on growth performance, carcass evaluation, intestinal morphology, microbial count and nutrient digestibility. The results showed that growth response of pigs fed the experimental diets were not significantly (P>0.05) affected across the levels of BSF used. Full gut which was significantly (P<0.05) influenced in pigs on 20, 0, 10% diets recorded highest percentage while 30% recorded least percentage. Lamina propria depth were not influencedsignificantly (P>0.05) with highest of 337.50 in pigs on 20% diet. In digestibilityparameters measured were not significantly (P>0.05) influenced by the percentage BSF replaced soy bean. Total bacterial Count had the highest(P<0.05) value of (1.25) in pigs on the control diet compared to other percentage BSF replacement of soy beans. Urinary nitrogen, total nitrogen excretion and nitrogen retention were not significantly (P>0.05) influenced by the levels of BSF used. The study concluded that the dietary inclusion of BSFLM did not significantly affect growth performance, nitrogen balance and nutrient digestibility of grower pigItem EFFECTSOF ACCESS TO LOAN ON THE FOOD INSECURITYSTATUS OF RURAL HOUSEHOLDS IN NIGERIA(2023-01-25) ADEDIGBA ISREALABSTRACT Historically, Nigeria has been plagued with declining food security, arising from inadequate agricultural financing. This menace had reduced the prospects of economic growth and increased the level of starvation in the country. Thus, this study evaluated the role of loan access on rural household food insecurity status in Nigeria. A multistage sampling procedure was used to select 14,671 rural households for the study. Secondary data on rural households’ socio-economic characteristics, sources of credit accessed, factors influencing credit use and food insecurity status of the rural households from the 2018/2019 Nigeria Living Standard Survey (NLSS) dataset was used for this study. Data collected were analysed using descriptive (frequency counts, percentages, means) statistics, the Foster, Greer and Thorbeck (FGT), Double Hurdle Model and Probit regression models. Results shows that 83.7% of the respondents were male, 57.1% were married and 62.2% had formal education with a mean age and household size of 48years and 6 persons respectively. Most (71.9%) of the respondents owned agricultural land but 53.5% have no right to sell land and 87.9% do not own agribusinesses. Also, 74.1% of the household heads applied for credit, and 25.9% obtained credit while 14.6% sourced their credit from friends/relatives with an average amount of ₦67,832.63 accessed. The Double Hurdle model results show that respondents’ age (t= -2.120; p<0.05), level of education (t= 5.941; p<0.01) and land ownership (t= 2.664; p<0.01) significantly influence amount of credit obtained while land ownership (t= 3.314), years of schooling (t= 5.334) and monthly income (t= 4.942) significantly (p<0.01) influence their accessibility to credit. The food security (FGT) results revealed that 44.4% of the households were food insecure. The Probit regression results reveal that age (β= 0.002; p<0.05), marital status (β= -0.061; p<0.05), sex (β= -0.276; p<0.01), years of schooling (β= -0.015; p<0.01), land ownership (β= -0.569; p<0.01) and ownership of non-agribusiness (β= -0.085; p<0.05) significantly influences the household food insecurity status. However, access to loan had no significant effect on the food insecurity status of the rural households (β= -0.045; p>0.05). This study concluded that loan access had not contributed significantly to the food insecurity status of the rural households in Nigeria. However, household becomes less vulnerable to food insecurity with increasing educational attainment, land ownership and involvement in non-agribusiness activities. Therefore, due to the importance of education in reducing food insecurity, educational development should be approached systemically while all stakeholders should prioritize the provision of credit to improve the living conditions of farming households in the rural communities.Item EFFECT OF AGGRESSIVE CONDITION ON THE DURABILITY OF UNDERWATER REINFORCED CONCRETE STRUCTURES AROUND THIRD MAINLAND BRIDGE LAGOS NIGERIA(2023-03-23) IGBA, Uvieoghene TobitItem EFFECTS OF MAGNETISED IRRIGATION WATER AND SEEDS OF COWPEA ON WATER USE EFFICIENCY, UPTAKE OF NUTRIENTS AND ITS YIELD(2023-04-23) ADEBAYO, Kehinde RaheefItem MODELING AND ANALYSIS OF LOW RESOLUTION MILLIMENTER WAVES ARCHITECTURE FOR COMMUNICATION(2023-04-26) RAJI, Akeem AbimbolaItem HYDROGEN EVOLUTION VIA PROTON REDUCTIN CATALYZED BY 1,10- PHENAATHROLINE ADDUCTS OF EARTH - ABUNDANT DITHIOCARBAMATE(2023-05-02) SHOTONWA, Ibukun OluwaseunItem EVALUATIONOF QUALITY ATTRIBUTES OF GUINEAFOWL SEMEN SUBJECTED TO DIFFERENT CRYOPROTOCOLS AND CENTRIFUGATION(2023-06-12) ASHAWE ESAN ADEBISIItem ASSESMENT OF ABBATTIORS' HYGIENE STATUS PATHOGENIC BACTERIA MEAT CONTAMINATION AND ASSOCIATED HEALTH RISK IN EDO STATE, NIGERIA(2023-06-20) OBAYAGBOLA NOSA OMOREGBEItem ENHANCING IRIS AUTHENTICATION: A GRADUAL FEATURE SELECTION APPROACH AUGMENTED WITH SOFT VOTE ENSEMBLI NG(2023-06-29) OMOJOLA, ABIODUN FOLURERAItem ANALYSIS OF INDEGENOUS KNOWLEDGE SYSTEM FOR WEATHER MONITORING AND PREDICTION OF FARMING SEASON IN OGUN STATE, NIGERIA(2023-07-20) ISKIL-OGUNYOMI SAFIAT ADEKEMIItem PREVALENCE AND MOLECULAR CHARACTERISATION OF HERPESVIROSES IN CAPTIVE MONKEYS IN ZOOLOGICAL FACILITIES IN SOUTH WEST NIGERIA(2023-07-20) EGBETADE ADENIYI OLUWAGBENGAItem DEVELOPMENT AND EFFICACY OF BIOPESTICIDE FROM AGRICULTURAL WASTE IN THE CONTROL OF FIELD AND POST-HARVEST LOSSES OF COWPEA AND MAIZE(2023-07-20) LASISI SAMSONDEEN ABIDEMIItem SUBSTITUTION OF WHEATH OFFAL WITH SOYABEAN HULL SUPLEMENTED WITH OR WITHOUT MULTI-ENZYME IN THE DIETS OF MEAT AND EGG-TYPE CHICKENS(2023-07-20) OGBONNA CHINNA CLAVERItem GENETIC DIVERSITY AND INTER-CHARACTER ASSOCIATION AMONG AGRO-MORPHOLOGICAL TRAITS lN OKRA (Abelmoschus esculentus L.)
