This study was conducted to determine the impact of banditry on food security, challenges faced by farmers, and the solutions in the Ndokwa–East, Ndokwa-West, and Ukwuani Local Governments Areas of Delta State. One hundred and fifty-five (155) farmers were used. A purposive sampling technique was also used. Structured questionnaires with forty (40) items of four (4) a point scale consisting of Strongly agreed (SD) Agreed (A) Disagreed (D) Strongly disagreed (SD), with a numerical weight score of 4,3,2,1 respectively was used to collect information from the farmers. Data collected were analyzed using simple percentages and simple statistical means. A decision rule was established where any item with a mean above 2.50 was accepted and items with a mean below 2.50 were rejected. The farmers disclosed that the conflict between the farmers and herders which has resulted in violence and communal clash has led to the loss of lives of many farmers and also displaced many farmers from their homes and this has added to untold challenges of food security in Nigeria which is a big threat to food production leading to abject hunger and starvation. It was recommended that the host community use community vigilantes in the local government area and negotiate with the Fulanis leaders to reach a common understanding of peaceful co-existence.</p> Joan Nneamaka Eze, Patience Okafor, Teslim Ademiju Copyright (c) 2025 Joan Nneamaka Eze, Patience Okafor, Teslim Ademiju https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/Banditry Wed, 26 Mar 2025 00:00:00 +0000 Mining effluent impact on selected soil physical quality parameters in agricultural land Daba, Kwara State, Nigeria https://www.ajol.info/index.php/drjafs/article/view/miningeffluents <p>The study examined soils' physical, chemical, and selected soil water transmission properties in an unregistered mining community in Moro Local Government Area, Kwara State, North-Central Nigeria. The assessed agricultural lands based on the reconnaissance survey were 400 m and 800 m away from the mine site, and 1200 m (forested area) away from the mine site. A 25 m x 25 m plot was demarcated and replicated three times in each farmland and mining site. Soil samples were obtained from 0 to 15 cm soil layer at 5 m x 5 m subplot level and analyzed for particle size distribution, pH, organic C, total N, available P, exchangeable Ca<sup>2+</sup>, Mg<sup>2+</sup>, K<sup>+</sup>&nbsp;and Na<sup>+</sup>, total acidity and selected heavy metals (Zn and Cu). Infiltration tests were run using the double-ring infiltrometer. Sixty soil core samples were collected from the study area to determine the water-holding capacity, bulk density, and hydraulic conductivity. The study showed that soil particles at mining sites were loamier and contained a significantly higher concentration of heavy metals but lesser concentrations of some soil nutrients than in the farmlands and the forested areas. The study also revealed that hydraulic conductivity and bulk density trends vary between 400 and 800 m from the mining site but within the recommended range of the soil-water transmission pathway. As a result, the mining effluent seems to have little impact on the water retention capacity of the soil's water transmission system, and plants growing in that region will not suffer a distorted soil water flow.</p> Adesina Abudlkabir Wahab, Sikiru Yusuf Alasinrin, Toyeeb Abayomi Abioye, Kola Agboola, Oluseyi Abel Aina Copyright (c) 2025 Adesina Abudlkabir Wahab, Sikiru Yusuf Alasinrin, Toyeeb Abayomi Abioye, Kola Agboola, Oluseyi Abel Aina https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/miningeffluents Tue, 25 Feb 2025 00:00:00 +0000 Quality evaluation, mineral composition and vitamin content of “Ndaleyi” (millet stiff forage) produced from pearl millet (Pennisetum glaucum) and Bambara-nut flour blends https://www.ajol.info/index.php/drjafs/article/view/PearlMillet <p>“Ndaleyi” is a fermented sundried agglomerated powder produced from pearl millet which is widely consumed across all ages of the royal families in the north western Nigeria, mostly by the Kanuri people of Borno State. It is prepared from reconstitution of starch flour with cold water to form slurry and added to the boiling water containing groundnut oil (to avoid sticking) with continuous stirring to form a thick gruel. The study focus on production, proximate, functional, minerals, vitamins and acceptability of ndaleyi produced by substituting millet flour with bambaranut flour, were evaluated at different proportions (10, 20, 30, 40 and 50 of bambaranut flour). ndaleyi prepared with 100% of millet flour served as control. Results showed that “ndaleyi” (millet stiff forage) had significantly increased in ash, protein, fat, crude fibre with decreased in carbohydrate than the control M (100% millet). Variation in functional properties of the flour, sample MBN<sub>2&nbsp;</sub>had higher amount of iron (11.29mg/100g), potassium (466.90mg/100g), and magnesium (316.67mg/100g). Vitamin c significantly decreased with increased in riboflavin resulting from substitution with bambaranut flour. Sample MBN<sub>2&nbsp;</sub>was overall accepted when compared with the control followed by samples MBN<sub>1</sub>&nbsp;and MBN<sub>3&nbsp;</sub>This also showed that all the formulations shows a significant difference based on the sensory attributes such as thickness, colour, flavor, texture and overall acceptability.</p> Fatima Abubakar, Aminu Barde Copyright (c) 2025 Fatima Abubakar, Aminu Barde https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/PearlMillet Tue, 25 Feb 2025 00:00:00 +0000 Cost implications of in situ solarization on cassava (manihot esculenta crantz) production in the humid agroecosystem of Southern Nigeria https://www.ajol.info/index.php/drjafs/article/view/289917 <p>A two year experiment was conducted in 2019 and 2020 cropping seasons to investigate the cost implications of in situ soil solarization duration using different colours of plastic film in cassava production. Designed as a factorial combination of two plastic colour (transparent and black) and five mulching duration (48, 16, 12, 8 and 0 weeks), arranged in randomized complete block design (RCBD) replicated thrice. The cost implication of the technology was analyzed by computing the production cost, total revenue, net returns, benefit/cost ratio and percentage net returns of each treatment. Results showed a higher production cost and revenue of the solarized plots relative to the unsolarized plot. The highest average percentage net returns of 69.13 % and 69.21 % were obtained from the blocks solarized for 48 weeks using black and transparent plastic, respectively, while the lowest 36.29 % was recorded on the unsolarized plot. In situ solarization for 48 weeks gave the highest economic returns and is therefore recommended.</p> OKechukwu Chidiebube Umunnakwe, Emmanuel Bassey Effa, Ozoemena Bernedette Bisong, Bini Onen Ebri, Emmanuel Abiodun Awelewa, Oluwatomiwa Samuel Olatunji Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/289917 Sun, 26 Jan 2025 00:00:00 +0000 Assessment of mutation induced bruchid (Callosobruchus spp.) resistance in cowpea https://www.ajol.info/index.php/drjafs/article/view/Bruchid <p>A study was carried out at the Joseph Sarwuan Tarka University, Makurdi located at latitude 7.41<sup>0</sup>&nbsp;N and longitude 8.39<sup>0&nbsp;</sup>E. The laboratory experiment was carried out in the Plant Breeding and Seed Science laboratory of the University. The objective of the study was to assess the cowpea induced mutants for bruchid resistance. This is to mitigate the post-harvest losses experienced by farmers to bruchids. Genotypes used in the study were Fuampea 1, IFE BROWN and Sampea 14. The seeds were subjected to mutagenic treatment using experimental grade Ethyl Methane Sulphonate (EMS), Sodium Azide (SA), Hydroxylamine Hydrochloride (HH) at 0.01%, 0.05% and 0.1. The seeds obtained from this mutagenesis experiment in the fourth mutant generation were used to test for bruchid resistance. Bruchids were cultured and subsequent treatment of the mutant cowpea genotypes were carried out and data recorded. Results from Analysis of Variance showed that there was significant (P&lt;0.01) genotype effect only for holes in seeds and mean development period. Mutagen effect was significant (P&lt;0.01 and P&lt;0.05) for only holes in seeds and number of eggs. Dose effect was also significant (P&lt;0.01 and P&lt;0.05) for holes in seeds. Genotype x Mutagen x Dose had significant (P&lt;0.01 and P&lt;0.05) variation in all the measured traits except for percentage bruchid emergence, percentage pest tolerance and growth index. From the present study it can be concluded that; EMS induced the only above susceptible resistance on the Dobie’s Index among the genotypes studied. EMS could potentially be used to induce bruchid resistance in cowpea.</p> Sorishima Mlahaga Liamngee, Terkimbi Vange, Ene Abigail Ochigbo, John Ochoche Okoh Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/Bruchid Fri, 31 Jan 2025 00:00:00 +0000 Effects of different roofing materials on the growth performance, haematological profile and welfare of broiler chickens https://www.ajol.info/index.php/drjafs/article/view/Heatstress <p>This study investigated the effects of different roofing materials on the growth performance, haematological profile and welfare of broiler chickens. Thirty-six (36) 4-week-old Arbor Acre broiler chickens were randomly allocated to three treatment groups: houses covered with corrugated iron roofs (CIR), (houses covered with asbestos cement roofs (ACR), and (houses covered with tarpaulin roofs (TPR), with 12 birds per treatment replicated thrice at four birds per replicate. The birds were reared for 28 days under controlled conditions, and data on ambient temperature, feed intake, body weight, weight gain, feed conversion ratio (FCR) and haematological parameters were collected. Results revealed significant differences (p &lt; 0.05) in the ambient temperatures across treatments. The CIR group recorded the highest average temperature (33.13°C), followed by TPR (28.89°C) and ACR (27.11°C). Growth performance metrics, including feed intake, weight gain and FCR, were significantly lower in the CIR group compared to the ACR and TPR groups, which exhibited statistically similar performance. Haematological analysis showed higher levels of heterophil, basophil and heterophil-to-lymphocyte (H/L) ratios in the CIR group, indicating increased heat stress levels. In contrast, ACR and TPR groups exhibited higher levels of lymphocyte, monocyte, haemoglobin and haematocrit. Due to their high thermal conductivity, corrugated iron roofs resulted in heat stress, reduced growth and impaired haematological parameters. Conversely, asbestos cement and tarpaulin roofs provided better thermal insulation, enhancing growth performance and welfare. It was concluded that roofing materials influence the growth performance, haematological parameters and welfare of broiler chickens.</p> Akinbobola Akinwemoye, Muyiwa Adegbenro, Olayele Ogunnusi Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/Heatstress Thu, 06 Feb 2025 00:00:00 +0000 Nutrient utilization and blood profile of broilers fed with unpeeled yellow cassava root meal (UMUCASS-46 or TMS01/0539) https://www.ajol.info/index.php/drjafs/article/view/haematology <p>An eight-week old experiment was conducted to investigate the&nbsp;nutrient utilization, haematological and serum biochemistry of broilers fed&nbsp; with unpeeled yellow cassava root meal (UYCRM). The unpeeled yellow cassava root was harvested, washed, ground and toasted. This was incorporated in graded levels of 0% (control), 25%, 50% and 75% into the diets designated T<sub>1</sub>&nbsp;, T<sub>2</sub>, T<sub>3</sub>&nbsp;and T<sub>4&nbsp;</sub>respectively. One hundred and twenty Anak, day&nbsp; old broiler chicks were randomly allotted to the four dietary treatments in a Completely Randomized Design (CRD). Each treatment consisted of 30 birds, replicated three times with 10 birds per replicate. Nutrient digestibility of the birds revealed a significant (P&lt;0.05) variation in all parameters with the exception of dry matter and ash. Digestibility values for crude protein (9.083%), ether extract (0.047%), crude fibre (8.163%) and metabolisable energy (1938.747kcal/kg) were observed to highest in birds fed 75% UYCRM. Haematology and serum biochemistry values, although higher in the control, were in conformity with standards for healthy broiler birds. Up to 75% of UYCRM can be incorporated into broiler diet without negative effect on the digestibility, haematology and serum chemistry. Diet T4 was then recommended.</p> Olubukola Olajumoke Adedokun, Kamorudeed Kolawole Safiyu, Luke Kehinde Akinsola, Merit Chisom Osigwe, Uchechukwu Okah, Gbolagunte Sunday Ojewola Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/haematology Fri, 07 Feb 2025 00:00:00 +0000 Biochar and poultry manure application effects on selected soil chemical properties and bioaccumulation of heavy metals in maize plant cultivated on degraded soils https://www.ajol.info/index.php/drjafs/article/view/poultrymanure <p>With the rapid development of industrialization and overpopulation, a significant number of heavy metals have been produced and entered the soil through anthropogenic (illegal mining) interference, and has become an issue of global focus. Soil samples for this study were collected in degraded farmland in Amagu, Abakaliki, Nigeria. The study evaluated the effect of composted poultry manure and biochar on heavy metals (Lead, Copper, and Zinc) in degraded soil and its bioaccumulation in maize plants. Biochar from three feedstocks were pyrolyzed at 42<sup>0</sup>C, while poultry manure from battery cage system was composted for 90 days before application. The study was a 4 × 2 factorial experiment in a completely randomized design. The soil's physical and chemical properties were analysed before treatment. The application of Composted poultry manure (CPM) and biochar sources reduced the acidity of the soil and recorded a significant increase in the organic carbon content. After harvest, Pb still exceeded the Food and Agricultural Organization (FAO) permissible limit of 100 mg/kg in Agricultural soils, but reduced significantly in the root region. CPM showed a significant (P≤0.05) increase by 33 % of the amount of Pb in the shoot after harvesting. Significant increases were recorded in the level of copper in the shoot across the biochar treatments. About 140 % reduction of Zinc in the soil was recorded after composted poultry manure was applied. The application of the organic treatments varied in their effects on different elements and plant bioaccumulation mechanisms. The amount of Pb in the root and shoot reduced after the application of biochar and poultry manure.</p> Ikwuakonam George Okoro, Abimbola Oluwatosin Babalola, Joshua Kayode Adesodun, Adewole Michael Gbadebo, Olayinka Ibiwumi Nwachukwu Copyright (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/poultrymanure Sat, 08 Feb 2025 00:00:00 +0000 Comparative studies of chemical and sensory properties of functional neem fruit juice and commercial orange juice https://www.ajol.info/index.php/drjafs/article/view/micronutrient <p>Micronutrient deficiencies, often termed "hidden hunger," pose significant global health challenges. Underutilized local resources, such as Neem (Azadirachta indica), present opportunities to improve dietary intake and public health. Neem juice, rich in essential vitamins and minerals, has been identified as a potential nutritious beverage. This study aims to compare the nutritional composition and sensory properties of fresh Neem juice with commercially available orange juice, evaluating their potential health benefits and implications for addressing micronutrient deficiencies. Fresh Neem fruits were sourced, and juice was extracted for analysis. The proximate composition, including water, energy, protein, fat, carbohydrates, sugars, dietary fibre, and ash, was determined using standard AOAC methods. Mineral content (calcium, iron, phosphorus, magnesium) and vitamin C levels were also analysed. A sensory evaluation was conducted with panellists assessing the juices on appearance, taste, texture, and overall acceptability. Data were statistically analysed using ANOVA and Duncan’s test. Our study revealed that Neem juice has a lower energy content (20-30 kcal) compared with control juice (42-45 kcal) but contains higher protein levels (1-2 g) and lower sugars (1-3 g). Vitamin C content was significantly higher in Neem juice (35.51 μg RE) compared with control juice (29.41 μg RE). Sensory evaluations indicated that while control juice was preferred for appearance and aroma, Neem juice was favoured for its taste and texture. Neem juice presents a promising alternative beverage with unique nutritional benefits, particularly for those seeking lower sugar intake and additional protein. Incorporating Neem juice into diets could contribute to addressing micronutrient deficiencies and enhancing public health, warranting further research to improve its market acceptance and utilization as a functional food.</p> Queen Chisom Adeoye-Agomoh Copyright (c) 2025 Queen Chisom Adeoye-Agomoh https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/micronutrient Wed, 12 Feb 2025 00:00:00 +0000 Assessment of the socioeconomic factors affecting smallholder rice farmers' use of ICTS to access market information in Nasarawa State, Nigeria https://www.ajol.info/index.php/drjafs/article/view/RiceFarmers <p><em>The study assessed the socioeconomic factors affecting smallholder rice farmers' use of ICTs to access market information in Nasarawa State. A multi-stage sampling technique was used to sample respondents for the study, while primary data was used for the study, collected with a well-structured questionnaire. The study's objectives were achieved using descriptive statistics such as frequency, percentage, and mean, as well as chi-square test and multiple regression analysis. The result revealed that the majority (70.7%) of the respondents were male, with a mean age and household size of 39 and 6, respectively. Most (38.6%) of the farmers had secondary education, 64.3% did not belong to cooperative societies, and 68.1% had farming as their primary occupation. The average farming experience, farm size, and annual income of the farmers were 11 3.187 and N471, 312.68, respectively. The majority, 93.9%, of the farmers never used ICT to access market information and digital skills such as basic computer knowledge, navigation of the internet, email marketing, digital marketing, and search engine optimization. The result of the regression analysis showed that gender, age, membership of cooperatives, farming experience, farm size, and annual income of the farmers significantly influenced the use of ICT to access market information. The study, however, revealed that the cost of ICT devices, limited access to a reliable internet connection, lack of digital literacy skills, unavailability of information tailored to meet specific needs, and lack of funding were the major hindrance to the use of ICT to access market information by smallholder rice farmers. The study recommends that efforts be put in place by the state government to increase digital literacy and training to improve digital literacy among smallholder rice farmers.</em></p> Edwin Ejoga Idu, Samson Olayemi Sennuga, Ajuma Owoicho Copyright (c) 2025 Edwin Ejoga Idu, Samson Olayemi Sennuga, Ajuma Owoicho https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/RiceFarmers Thu, 13 Feb 2025 00:00:00 +0000 Effect of incorporating Zamarke (Sesbania rostrata) as a green manure on some soil physicochemical properties in Sudan Savannah Zone, Aliero, Kebbi State Nigeria https://www.ajol.info/index.php/drjafs/article/view/Soil <p>A Field experiment was conducted at the University Botanical Garden, in Kebbi State University of Science and Technology, Aliero, Aliero local Government area, to evaluate the effect of incorporating Sesbania rostrata as a green manure on the early growth of maize (Zea Mays L.). The experiment consists of four treatments; Control, Green manure (Sesbania rostrata), NPK Fertilizer (20:10:10) and intercropped Sesbania plant (as T1, T2, T3 and T4 respectively) that were fitted into Randomized Complete Block Design (RCBD) and replicated three times. Results from the experiment indicated that the most effective practice on germination count (%), plant height and leaf area of the Maize plants, in most cases at latter stage of the growth was found with T2 (Green manure) with 90.27% at 15 DAP, 22.88cm, and 11.60cm2 respectively, and T3 ranked the second with 82.34%at 15 DAP, 18.70cm and 18.80cm<sup>2</sup> respectively. However, in most cases, T3 (NPK Fertilizer) gave a similar effect as that of T4 (intercropped Sesbania plant). Germination count (%), Plants height and leaf area were highest with green manure treatment (T2), while the rest, in most cases, were statistically similar. Green manure treatments gave highly significant effect on the growth parameters, of 90.27% at 15 DAP, 22.88 cm, 11.60 cm<sup>2</sup> for germination count (%), Plants height and leaf area respectively over the control treatment with 81.94% at 15DAP, 8.87cm and 4.77cm<sup>2 </sup>at the latter stage of growth, while they were unaffected by green manure treatments at early stage that is at 1WAP. Green manure of Sesbania rostrata was found to be the best management practice to be used in improving soil fertility and growth of Maize particularly for the study area. To achieve an increased and sustainable maize production in the study area, with less use of inorganic fertilizers, there is need to adopt a green manure cropping system that is environmentally friendly and can improved nutrient availability to crops.</p> Aminu Muhammad, A.

This study investigates the nutritional potential of defatted Moringa oleifera seeds in ameliorating PEM in albino rats. Moringa oleifera seeds were defatted to enhance protein concentration. The seeds' proximate composition, mineral elements, amino acid profile, and in-vitro protein digestibility were analyzed. Additionally, the effects of Moringa oleifera seed based-diet on liver function indices of Protein energy malnourished rats were assessed. Results indicated that defatting significantly increased crude protein content and reduced crude fat level. Mineral analysis revealed high sodium and calcium concentrations, essential for electrolyte balance and bone health. Amino acid profiling showed a significant (p &lt; 0.05) increase in essential amino acids, particularly arginine, leucine, and valine, which are crucial for tissue repair and muscle growth. In-vitro protein digestibility improved significantly after defatting, with the highest digestibility observed in seeds defatted with the solvent mixture. Protein energy malnourished rats exhibited significantly (p&lt; 0.05) elevated serum level of alanine amino transferase, aspartate aminotransferase and alkaline phosphatase, conjugated and total bilirubin and significantly (p &lt;0.05) reduced plasma protein levels (total protein, globulin and albumin), indicative of liver dysfunction. Treatment with the Moringa oleifera kernel-based diet resulted in significant reduction on these liver enzymes and significant increase in the serum protein compare to the malnourished control group. The diet normalized enzyme activities and increased plasma protein levels, suggesting liver recovery. The study concludes that defatted Moringa oleifera seeds is a viable, cost-effective alternative protein source for managing PEM, exhibiting promising nutritional and functional properties.</p> Raphael Eneji Jegede, Gideon Ayeni, Rose Mafo Abaniwo, Abdulquadri Funmbi Olutoye, Godwin Amoka Audu, Abdullahi Haruna, Oluwabusayomi Stella Oluwole Copyright (c) 2025 Raphael Eneji Jegede, Gideon Ayeni, Rose Mafo Abaniwo, Abdulquadri Funmbi Olutoye, Godwin Amoka Audu, Abdullahi Haruna, Oluwabusayomi Stella Oluwole https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/seeds Fri, 07 Mar 2025 00:00:00 +0000 Evaluation of full-fat and defatted black soldier fly larvae (Hermetia illucens) meal as an alternative source of functional feed ingredients https://www.ajol.info/index.php/drjafs/article/view/meal <p>This research work presents the proximate, minerals and anti-nutritional factors of full-fat and defatted black soldier fly larvae (Hermetia illucens) meal. The Black soldier fly larvae was reared and supplied by a commercial company (The Fly Colony, Ilishan Remo, Ogun State), Harvested larvae was dried in an oven at 90OC and milled afterwards using local blender. Milled Black Soldier Fly Larvae meal was defatted using food grade hexane. Results from the proximate analysis showed that full-fat and defatted BSFL meals had appreciable amount of dry matter (96.29% and 92.54%), crude protein (46.03% and 54.53%), and also with high value for ether extract which are 29.91% and 10.81% respectively. The meals also had lower values of crude fibre (6.80% and 6.94%). The mineral analysis showed that the meals had sodium (0.48% and 0.54%), potassium (1.79% and 1.87%), calcium (0.29% and 0.30%), while the micro minerals showed that full-fat and defatted BSFLM had appreciable concentration of iron (874mg/kg and 893mg/kg), zinc (97.67mg/kg and 114.80mg/kg) and copper (34.59mg/kg and 46.41mg/kg). the anti-nutritional factor constituents of full-fat and defatted BSFLM showed that phytate concentration was (0.09% and 0.17%), tannin (0.12% and 0.24%), haemagluttinin (39.74HU/mg and 55.37HU/mg) and trypsin inhibitor (11.68TIU/mg and 18.70TIU/mg) respectively. This study showed that full-fat and defatted BSFLM can be good sources of protein, ether extract, carbohydrate and minerals. Therefore, these meals can be exploited as commercial source to supplement livestock feedstuff.</p> E. M. Afam-Ibezim, A. H. Akinmutimi, M.C. Ugwuene, D. N. Onunkwo, U. K. Oke, R. S.

The birds were randomly assigned to five treatments/diets in a Completely Randomized Design (CRD). Each treatment was made up of three replicates with 10 birds per replicate. With the exception of treatment one (T1) which is the control, the other treatments T2, T3, T4 and T5 contained incorporated full-fat Black Soldier Fly Larvae Meal (BSFLM), as replacement of fishmeal in the diets of broiler chickens at 25%, 50%, 75% and 100% respectively. The result showed that there were no significant (P&gt;0.05) differences in values obtained for growth parameters except FCR. The FCR of diet 3 (50%) showed significantly (P&lt;0.05) lower value than other diets (T1, T2, T4 and T5). Diet 3 (50%) showed significantly (P&lt;0.05) higher values for cut-parts, especially in the prime parts (drumstick and thigh). Diet 3 (50%) also compared favourably with other treatment diets for organ weights. Conclusively, 50% replacement of fishmeal gave the best performance when full-fat BSFLM was fed to broiler chickens and is therefore recommended.</p> E.M. Afam-Ibezim, A.H. Akinmutimi, M.C.

However, conservation challenges such as overfishing, habitat degradation, and illegal fishing practices threaten its sustainability. Understanding the attitudes of fishing communities towards conservation measures is essential for effective fisheries management. This study assessed the perceptions, compliance behaviors, and influencing factors among fishermen at Kagwara Landing Site, the largest fishing hub on Lake Kyoga in Teso Sub-Region. A mixed-methods approach was used, combining structured questionnaires, focus group discussions, and direct observations. A total of 297 fishermen participated in the survey. Purposive and stratified sampling techniques were applied during the study. Results indicate that while some fishermen recognize the ecological benefits of conservation measures, a significant proportion perceive them as unfairly enforced, restrictive to their livelihoods, or difficult to comply with. Gear regulations (52%) and licensing requirements (24%) were the most disliked measures, primarily due to economic hardships and enforcement inconsistencies. Economic constraints (41%) and corruption (23%) emerged as the leading factors influencing non-compliance. The study findings further evidenced continuous use of illegal fishing gears and fishing of undersize fish (79%) at Kagawara Landing Site on Lake Kyoga. Despite resistance, 60% of respondents acknowledged improvements in fish stocks due to conservation efforts. The study highlights the necessity of integrating community concerns into conservation policies, strengthening enforcement mechanisms, and promoting alternative livelihoods to improve compliance. A participatory approach, involving local stakeholders in policy design and implementation, is crucial for fostering sustainable fisheries management in Lake Kyoga. These findings provide policymakers with data-driven insights to enhance conservation strategies while ensuring the socio-economic well-being of fishing communities.</p> Jackson Mulokozi Copyright (c) 2025 Jackson Mulokozi https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/Attitudes Wed, 12 Mar 2025 00:00:00 +0000 Ticks infestations and parasitism in resident and non-resident dogs of Plateau State, Nigeria https://www.ajol.info/index.php/drjafs/article/view/dogs <p>The aimed of the study was to determine tick infestations and parasitism in resident and non-resident dogs of Kanke Local Government Area, Plateau State, Nigeria and was carried out from November 2023 to October 2024. A total of five hundred (500) dogs were examined for ticks, out of which 421(79.0%) were infested with ticks. Three species of ticks were discovered infesting dogs in the study area. These are Boophilus decoloratus, Rhipicephalus sanguineus and Amblyomma variegatum (Ixodid or hard ticks). The dogs had multiple infestations with no single presence of tick found. Rhipicephalus sanguineus had the highest prevalence rates of 901(31.0%) and 2009(69.0%) in resident and non-resident dogs respectively. Boophilus decoloratus recorded an infection rate of 455(22.1%) in resident dogs and 1603(77.9%) in non-resident dogs. 99(43.2%) and 130(56.8%) prevalence rates for Amblyomma variegatum were recorded in resident and non-resident dogs respectively. The ticks recorded were mostly found on the facial region, followed by the trunk, interdigital cleft, anal region and lastly the abdominal region. Adult dogs were heavily infested with all the species of ticks encountered when compared with puppies. (P&lt;0.05). This study revealed that Babesia canis was the only tick-borne parasite present in the examined blood samples of the animals. This haemoparasite was more prevalent in non-resident dogs. Adult dogs were mostly infected with Babesia canis. The examined animals showed an association of tick infestations and babesiosis. The present study, therefore revealed multiple tick infestations with monoparasitism in the dogs. Both resident and non-resident dogs showed a decrease in PVC levels due to tick infestations. Packed cell volume indicated significant difference in the studied dogs (P&lt;0.05), thus aneamic, emaciated and loss economic and meat value to the farmers and consumers respectively.</p> Paul Davou Kaze, Daniel Velshang Dakung, Dung Davou Pam Copyright (c) 2025 Paul Davou Kaze, Daniel Velshang Dakung, Dung Davou Pam https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.ajol.info/index.php/drjafs/article/view/dogs Thu, 13 Mar 2025 00:00:00 +0000
