Widespread aflatoxin contamination of maize is a public health hazard in Sub-Saharan Africa and its management requires strategies which are implemented both at pre-and post-harvest stages of cereal production. This study aimed at assessing knowledge and practices for aflatoxin contamination of maize and factors associated with adoption of artisanal aflatoxin control technologies. A semistructured questionnaire was administered to 315 household heads that were practicing subsistence maize farming in Kitui, Kenya. Data were analyzed to determine farm level factors which were associated with aflatoxin contamination. Farmers in uplands areas had partial knowledge on occurrence of aflatoxin at pre-harvest stages of maize growth and effects of aflatoxins on animal health and productivity. Adoption of aflatoxin control technologies was higher in farms located in lowland areas as compared to uplands. There was evidence of association between adoption of control technologies and farm level factors including farmer's knowledge on aflatoxin contamination, farmer's level of education and location of farm. The results demonstrate a knowledge gap on aflatoxin contamination and farm level barriers for adoption of aflatoxin control technologies. The findings call for enhanced capacity building activities through extension to influence change on farming practices for farms with high risk of aflatoxin contamination.
Broiler farming creates wealth for farmers, but the system faces myriad constraints. The objectives of this study were to determine farmer's willingness to adopt welfare practices, farm biosecurity risks and cost of production from selected farms in Kenya. Primary data were collected using questionnaires from 60 medium-scale and 60 large-scale farms, and secondary data collected on product condemnation and downgrades from a large-scale broiler meat processing factory. Descriptive statistics were computed to estimate level of farm inputs and outputs, while framework analytical approach was used for qualitative data. A bio-economic model was used to estimate gross margins per farm. Medium-scale farmers were willing to forgo 30% of their income to implement welfare practices. The cost of mortality was 24,000 KSH per cycle for large-scale farms and 3,500 KSH for medium-scale farms. Feed accounted for over 60% of production costs in both farming systems, and gross margin per cycle was 548,230 KSH in large-scale farms and 37,890 KSH for medium-scale farms. There was uncontrolled use of antibiotics for treatment of sick broiler chickens in farms. Policy interventions are required to minimize production losses along the broiler value chains, and reduction of risks of disease and antibiotic resistance in connected farms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
