A survey of the farming systems of Vertisol areas of the Ethiopian highlands

In 1986, ILCA carried out informal surveys at Dogollo and Inewari in order to understand the farming systems. Such surveys were also conducted by the Institute of Agricultural Research (IAR) at Ginchi in 1986 and by the Alemaya University of Agriculture at Ada/Debre Zeit in 1988/89. This was followed by one-time detailed formal farm surveys at Dogollo, Inewari and Ginchi in 1988/89. This chapter mostly presents the results of these formal surveys. The objectives of the surveys were to understand the existing farming systems in order to develop appropriate Vertisol technologies, to identify production constraints and opportunities for technological interventions, to identify recommendation domain, and to compile baseline data in order to assist in ex-post Vertisol - technology evaluation. Natural resources, farm resources, crop and livestock interaction, feed production and livestock feeding, constraints to production, livestock production constraints and researchable areas are examined

Technology validation and transfer

As farming in Ethiopia is heavily dependent on animal traction, technologies that are based on this power source were envisaged to be appropriate for better management of Vertisols. Hence, the Joint Vertisol Project (JVP) began research on improved Vertisol technology that included 1) the use of an animal-drawn broadbed maker (BBM) to facilitate surface drainage and 2) the use of appropriate seeds, fertiliser and early planting. The aim of the technology verification and transfer were to verify the economic viability and acceptability of the BBM/Vertisol technology package and to popularies the technology so as to encourage large-scale adoption. A comparison of economic returns from crop grown with Vertisol technology package and traditional methods in selected Ethiopian highlands

The use of single oxen for crop cultivation in Ethiopia

Reports experiences with on-farm trials to assess the use of single oxen for work on mixed smallholder farms in the central highlands of Ethiopia, with particular reference to draft power and agricultural production, design and testing of the single ox technique, and results obtained during the 1983 crop year and future prospects with respect to feed requirements and advantages of using the single ox

Seroprevalence of infectious bursal disease and its potential risk factors in backyard chicken production of Waliso district, South Western Shoa Zone, Ethiopia

A cross sectional study on infectious bursal disease was conducted in apparently healthy backyard chicken at Waliso district of Southwestern Shoa, central oromia, Ethiopia from from November, 2018 to October, 2019. A total of 282 chickens were randomly selected to estimate seroprevalence of IBD infection and to identify the likely potential risk factors for the disease. Serum samples collected and serological test conducted in laboratory at National Animal Health Diagnosis and Investigation Center Sebeta, Ethopia. Out of 282 serum samples tested 224 were positive for indirect ELISA technique and the overall seroprevalence of IBDV in the study area was found to be 79.43% at individual level. Educational level of owners, kebeles and flock size significantly affect seroprevalence of IBD in the study area. The effect of difference in managements like source of replacement, frequency of house cleaning, use of disinfectant and isolation practice has a significant effect on IBDV sero-prevalence. A lower seroprevalence of IBDV was reported in good hygienic level of house (26.7%) than poor level of chicken house hygiene (96.4%) with statistically significant difference (P < 0.05). The seroprevalence of IBDV in the present study associated with chicken management, flock size, owner education level and other animal related risk factors for occurrence of the disease. Therefore, awareness on chicken health management, and importance of immunization would help to minimize the prevalence of the disease and play crucial role in the control of the disease. Furthermore, characterizing virus strains circulating in the area in future study is recommended

Systematic review of Ethiopian medicinal plants used for their anti-inflammatory and wound healing activities

Ethnopharmacological relevance: Plant materials are used worldwide as complementary and alternative therapeutics for the treatment of various illnesses. In Ethiopia, folk medicines are utilized across a wide range of cultures and settings. Ethiopia has numerous plant species of which around 12% are endemic, making it a rich source of medicinal plants that are potentially important for human wellbeing. Aim of the study: The aim of this study was to assess Ethiopian medicinal plants with anti-inflammatory or wound healing activities, in an attempt to compile the information required for further investigation of their potential role in the management of lymphoedema. Methods: A systematic review protocol was developed according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) statement. The protocol for this review was registered on PROSPERO with registration number CRD42019127471. This review considers all controlled in vivo and in vitro anti-inflammatory and wound healing studies evaluating the efficacy and safety of Ethiopian medicinal plants. The search strategy included all articles containing descriptors such as Ethiopia, medicinal plants, herbal products, care, management, lymphoedema, lymphedema, swelling, podoconiosis, elephantiasis, wound, wound healing, inflammation, and anti-inflammatory that were published up to June 28, 2019. Outcomes were measured as the percentage of inflammatory and pro-inflammatory cell inhibition, as the percentage of carrageenan-induced oedema (anti-inflammation) inhibition, and the percentage of cell migration and proliferation (wound healing). For quality assessment of individual animal studies, the Risk of Bias tool for animal intervention studies (SYRCLE’s RoB tool) criteria was used. For quality assessment of individual in vitro studies, the OECD guidelines and the WHO Good Laboratory Practice (GLP) handbook were used. Results: A total of 46 articles on anti-inflammatory and 17 articles on wound healing properties were reviewed. For the in vivo studies, Swiss albino mice and Wistar rats were used, and the concentration of plant extracts or fractions administered to the lab animals varied considerably. Acetone extract of Vernonia amygdalina showed the fastest anti-inflammatory activity at lower concentrations in carrageenan-induced paw oedema. Conclusion: Lawsonia inermis, Azadirachta indica, Achyranthes aspera, and Cuminum cyminum are the most studied plant species in terms of anti-inflammatory activity, while Lawsonia inermis and Azadirachta indica are the most studied for wound healing. The most common in vivo techniques used for the anti-inflammatory and the wound healing assays were carrageenan-induced paw oedema, and excision and incision wound models, respectively

Issues on livestock technology Development on smallholder farms in Ethiopia

Discusses some methodological issues on livestock technology Development in Ethiopia, also stresses that livestock projects that appeared promising were abandoned after project funding ceased because of mainly the inappropriateness of many of the methods used in the design and execution of the projects. Argues that livestock technology Development and transfer have to follow a bottom-approach instead of top-down approach, and outlines farm-level contributions of livestock; indicates that livestock have output, input, asset and security, and investment functions on smal mixed farms
