This research aimed at determining the prevalence of antibodies to infectious bronchitis virus in chickens in sokoto state Nigeria. The samples were collected from selected areas in each of the four Agricultural zones of Sokoto State. The overall sero-prevalence obtained was 346 (86.50%). The sero-prevalence of infectious bronchitis viral antibodies in indigenous and exotic chickens was 88.72% and 84.39% respectively, chi square showed no significant relationship between the two groups, the chi value was 1.603 and P value was 0.205 (>0.05%). In young and adult chickens sampled, the sero-prevalence was 89.50% and 82.87% respectively, chi square showed significant relationship between the two age groups with chi value 3.179 and P value 0.038 (<0.05), binary logistic regression for the two age groups showed no significant association with P= 0.09 (>0.05). The result in male and female chickens tested was 86.88% and 86.17% positives respectively showing slightly higher positives in males than in females with no significant statistical relationship using chi square, chi value was 0,043 and P value 0.836 (>0.05%). This study has provided an update on sero-prevalence of IBV in Sokoto State. It was concluded that there was high sero-prevalence of IBV in the chickens sampled in the State.

While the global consumption of chicken products especially chicken meat drastically increased over the years and the trend is expected to continue. Much of the increase in demand is in the developing countries coupled with demand for the four traditional feed ingredients; maise meal, soya bean meal, fish meal, and meat meal. In all three poultry production systems that are extensive, semi-intensive and intensive, a wide range of alternative feedstuffs should be available for use. Expanding populations will create greater demand for chicken products, and the importance of feed industry resources and production systems will increase. This therefore calls for a need to enhance efforts towards increased chicken productivity. This study, therefore, evaluated the growth performance, feed conversion efficiency, and cost-effectiveness of feed supplementation termite Macrotermes bellicosus for indigenous chicken diets. Three groups of twenty IC were placed on diets comprising prepared feeds with different termite inclusion levels (0%, 2.5% and 5%) for each group for six weeks. Results reveal that the termite supplementation provides high crude protein content (43.36%), which leads to enhanced weight gain but no significant differences in the FCR of ICs compared to conventional feeds. Supplementation at different levels offers varying outcomes regarding feed intake: IC on a diet T3 had a lower feed intake compared to T2 but registered higher FBW and SGR. The use of termites contributes to smallholder farms’ food security by providing a cheaper alternative to commercial poultry feeds; and also increases the market value of IC, thus, increasing the profitability of IC production","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134194549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pest is estimated to reduce maize yields by about 60%. FAW could cause crop losses of up to US$13 billion annually across sub-Saharan Africa, threatening the livelihoods of millions of resource-poor farmers worldwide. Governments have warned against the indiscriminate use of chemical pesticides that could undermine pest control strategies for smallholder farmers who rely heavily on natural enemies. Since the invasion of this pest in Kenya, there have been limited studies conducted on indigenous innovations to tackle the challenges of FAW infestation. There has also been limited knowledge of the effects of the indigenous innovations adopted by smallholder farmers on crop production. A total of 150 farmers from Busia, Siaya, and Vihiga counties were purposely sampled and appropriately informed about the indigenous innovations they developed to address and leverage FAW challenges with the help of well-structured questionnaires. The impact of indigenous innovations on crop production were evaluated. Analysis of quantitative data was performed using the Statistical Package for Social Sciences (SPSS) version 20 to facilitate descriptive and inferential analysis of the study variables and by carrying out the Binomial Logistic regression analysis for objectives i, ii, iii and iv, respectively.

Objectives were to identify the coffee production systems and practices used, identify the socioeconomic challenges associated with the uptake of recommended practices for coffee production, and identify the policy interventions to address the challenges associated with the use of recommended coffee practices. Farmers continue to register low coffee yields hence affecting their livelihoods and incomes and achieving maximum coffee production requires that farmers apply recommended practices since the quantity and quality of the crop rely on the practices used. A cross-sectional survey was conducted using simple random sampling and a total of 376 coffee farmers were sampled. Results indicated that Arabica coffee commonly grown has two major systems intercropping and mono-cropping. The coffee-recommended practices used were weeds control (23.7%), shading (21.5%), pruning (15.5%), fertiliser application (14.1%), pest and disease management (12.2%), water drainage management (6.6%), transplanting (4.0%), and seedbed preparation (2.7%). Statistically significant socioeconomic factors affecting the uptake of recommended practices for coffee were age [p=0.014], education level [p=0.002], labour [p=0.005], Farm size [p=0.001], farming experience [p=0.031], gender [p=0.031], land slope [p=0.048], un-accessibility to credit services [p=0.032], and plot ownership [p=0.049]. Policy interventions were farmer capacity building (35.1%), strengthening agricultural extension (23.7%), credit extension to the farmers (15.7%), re-visiting land reform policies (13.6%), and group formation (11.9%). The study concluded that coffee in the study area was grown under two production systems; intercropping and mono-cropping; the major coffee recommended practices used were; seedbed management, transplanting, pruning, shading, fertiliser application, weeds control, pest and disease management, and water drainage management. Socioeconomic factors like Education level, shortage of labour, farm size, experience in farming, gender, the slope of the land, un-accessibility of credit services, farmer age and plot ownership type were significant socioeconomic factors affecting uptake of recommended practices. Suggested policy interventions were re-visiting land reform policies, credit extension, capacity building, strengthening agricultural extension, and farmer group formation. More education and training for farmers, revisiting land policies, groups, associations and cooperative formation, and credit services extension are recommended.","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121499208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specific objectives were to; (i) assess the household livelihood changes resulting from smallholder participation in Compassion International programs; (ii) assess the level of beneficiary participation in Compassion programs, (iii) analyse the contribution of Compassion International to food production and security, and (iv) examine the challenges being faced by Compassion International that hinder their operations in rural settings of Uganda. The study adopted a descriptive survey design that applied both quantitative and qualitative approaches for data collection. Data was captured from 206 respondents using both a questionnaire and an interview schedule. Data was analysed using SPSS version 16 to generate both descriptive and inferential statistics. The study found that smallholder participation in Compassion International programs has resulted in livelihood changes such as; enhanced child education, household economic and spiritual empowerment, increased access to agricultural inputs, income-generating projects, and enhanced household capacities. The study also found that beneficiaries participated in compassion programs by attending organisation outreaches, seminars, and annual meetings, mobilising local resources towards the cause, participating in project activities, paying annual membership fees, and giving feedback on project activities and operations. Compassion International has contributed towards household food production and security of the household across the district by setting up agricultural support projects, mobilising farmers, providing agro-inputs, and facilitating extension service delivery. The study further established that; poor funding, corruption and misuse of funds, competition and poor power relations with the local government are the key challenges hindering Compassion International’s operations in the Bushenyi district. The study concluded that though smallholder farmer participation in compassion programs has resulted in improved livelihood changes for member households, there remains a huge socio-economic gap in the Bushenyi district. The organisations’ operations are still hampered by a number of challenges. The NGO needs to tackle poverty reduction dynamically, strategically, and comprehensively. This is because poverty is a multidimensional phenomenon that needs a multidimensional approach. There is a need to look at other categories of needy people in society such as the elderly, widows, and disabled persons, rather than placing emphasis on a category.","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124039982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aquaculture has then proven useful in supplementing the dwindling catch fisheries stocks, which have become incapable of supporting the growing population. Since its introduction in Africa, however, changes have been seen as it has contributed to food security and malnutrition and improved livelihoods by creating jobs and generating income. Currently, diversified products come from aquaculture practices both in inland and freshwaters, ponds, and intensification of aquaculture farming methods, which all put together boost the production to a higher level. Genetics has also been employed to ensure seeds produced for aquaculture are worth being cultured for production. A lot of fisher folks are benefiting both directly and indirectly making a living.
