Climate and land use land cover change and their interconnections with livestock feed resource management in Ethiopia
We assessed land use/ land cover changes from remotely sensed satellite imagery and compared this with households perceptions on availability/use of livestock feed resources and feed deficit management strategies since the 1973 in three districts representing the pastoral, agro-pastoral and mixed crop-livestock eco-environments of Ethiopia. We found that land use/land cover changes are proceeding in all eco-environments and that transitions are from grasslands, and forest lands to bush/shrub lands and crop lands in the pastoral site (Liben), from bush/shrub lands and grasslands to crop lands in agro-pastoral site (Mieso) and from bush/shrub lands, forest lands and grasslands to crop lands in the mixed crop-livestock site (Tiyo). The changes significantly affected livestock feed resources and feed deficit management strategies available to households. Over the last 30-40 years, grazing resources available to livestock keepers have been declining with resultant increase in the contribution of crop residues and other feeds from crop lands (weeds and crop thinnings) as compared to feeds from grasslands. The feed deficit management strategies of households are also changing significantly from mobility to herd management and feed conservation in the pastoral areas; from mobility to feed conservation and purchasing of feed in the agro-pastoral areas and from transhumance to feed conservation and purchase of feed in the mixed crop-livestock areas. Hence feed resources and their availability vary with time and eco-environments indicating the need for the development of eco-environment/site specific feed management strategies in order to support productive stock in the study areas and similar eco-environments
Modeling the response of tropical highland herbaceous grassland species to climate change:the case of the Arsi mountains of Ethiopia
AbstractGlobal warming is forcing plant and animal species to respond either through pole-ward or upslope migration to adjust to temperature increases, and grassland communities are not an exception to this phenomenon. In this study, we modeled the response of herbaceous species of grasslands within the Arsi Mountains in Ethiopia under no-migration and with migration scenarios to the projected 4.2°C increase of temperature by 2090 (under the A2 emission scenario). For 67 species of grasses and legumes, we determined the current and predicted altitudinal limits and calculated current and projected area coverage using a Digital Elevation Model. The results indicated that the projected warming significantly reduced altitudinal ranges and habitat areas of all the species studied. All the studied species faced range contraction and habitat loss with range shift gaps among forty two species under the no-migration scenario. With the migration scenario, however, the forty two species with range shift gaps are predicted to benefit from at least some habitat area retention. Between growth forms, legumes are predicted to lose significantly more habitat area than grasses under the no-migration scenario while no significant difference in habitat area loss is predicted under the migration scenario. It can be concluded that management options are required to facilitate upslope species migration to survive under the warming climate. This could involve leaving suitable dispersal corridors and assisted colonization depending on species behavior and level of extinction risk predicted under the projected warming
Predictors of early neonatal mortality at a neonatal intensive care unit of a specialized referral teaching hospital in Ethiopia
Background: The larger fraction of infant mortality is that of neonatal; and early neonatal death is the most significant contributor of neonatal mortality as a whole. There are various factors which may be associated with early neonatal mortality and they have been the reasons for the wide variation in mortality rates among the health facilities reporting.Objective: This study was made to assess the independent predictors of early neonatal mortality.Methods: From 2001 through 2005, a total of 3789 live born neonates, who were admitted to the neonatal intensive care unit of Tikur Anbessa Hospital, were included in this study. Variables were classified into two: Socio economic/reproductive factors and maternal/newborn factors. Predictors were assessed using a multivariable binary logistic regression. Variables with a p-value of <0.05 were entered into a multivariable logistic model.Results: From the socio-economic/reproductive variables: age less than one day (AOR=2.53 95% CI= (1.66, 3.85)), having three or more siblings (AOR=2.04, 95% CI= (1.15, 3.64) ), second birth order (AOR=1.79, 95% CI= (1.28, 2.51)), absence of antenatal care (AOR=1.70, 95% CI= (1.28,2.26)), and being unmarried (AOR=1.55 95%CI= (1.20,2.00)) were independent predictors of increased mortality. On the other hand, singleton pregnancy was found to be protective by 30% against early neonatal mortality with an odds of 0.70, 95% CI of (0.54, 0.90). From the neonatal/ maternal variables: gestational age of <32 weeks (AOR= 10.46, 95% CI= (5.39, 20.31)), first minute APGAR of three or less (AOR=2.12, 95% CI= (1.39, 2.23)), presence of any congenital anomaly ( AOR=2.02, 95% CI=(1.33,2.51)), presence of peri-natal asphyxia (AOR=1.82, 95% CI=(1.32,2.51)), any oxygen treatment (AOR=2.65, 95% CI=(1.89,3.72)), birth weight less than 1500 (AOR=9.64, 95%CI=(3.32,27.97)) were independent predictors of neonatal mortality. A normal weight at admission was protective of early neonatal mortality.Conclusion: There are many factors that could have influenced neonatal mortality in the current study. Antenatal care follow up is the key point of contact for planning and managing labor and delivery; it should be improved to control most other variables. The care provided to these high risk babies should also be maximized to reduce mortality in these risk groups
Exploring genetic variability among feed and food crops for accelerated improvement in biomass and nutritional quality traits in Ethiopia
Carcass Yield and Quality of Pork from Pigs Fed Graded Levels of Fig (Ficus sur) Fruits Mixed with Maize Grain
Twenty growing Yorkshire piglets of 27.8±1.4kg (mean ± SD) average initial weight were used to investigate the effect of feeding different proportions of ground Ficus sur fruits (FSF) mixed with ground maize grain (MG) on carcass yield and quality attributes. The experiment was conducted in randomized complete block design (RCBD) with four treatments and five replications per treatment. The treatment diets were: 100% FSF and 0%MG represented as (100FSF), 67% FSF and 33% MG (67FSF), 33% FSF and 67% MG (33FSF) and 0% FSF and 100% MG (0FSF). For all treatments protein supplement (NSC+SBM) was given to provide about 18% CP to make the ration isonitrogenous. Except for the slaughter weight, which significantly (P<0.05) increased with increase in MG level in the diets, all other carcass measurements and primal cuts did not differ (P>0.05) among the treatments. However, lungs (P=0.012) and gastro intestinal tract (GIT) (P=0.001) among the viscera organs were varied. None of the quality attributes of the pork significantly differed (P>0.05) in color, taste, flavor, juiciness, tenderness and texture among the treatments. This indicates that similar quality pork can be produced by feeding FSF as those fed with MG. It is, therefore, concluded that substitution of MG with FSFs in the diets of pigs can result in comparable carcass yield and quality attributes

Family Medicine needs assessment: Studying the clinical work of general practitioners in Ethiopia
Background and Objective: Some universities in sub-Saharan Africa have initiated Family Medicine (FM) residency programs. This study was conducted by FM colleagues at Addis Ababa University (AAU) in Ethiopia and the University of Toronto, Canada to inform the FM residency curriculum at AAU. It was designed to determine the clinical problems that family physicians in Ethiopia may encounter.Methods: We used a mixed methods approach: Modified time-motion study and brief interviews. We observed 46 general practitioners (GPs) across ten sites in Ethiopia. Trained observers recorded time-motion data while GPs conducted their daily work. This data was supplemented by brief interviews with the GPs.Findings: Clinical encounters occupied 82% of GP work. The common symptoms were digestive-abdominal pain (21% visits), respiratory-cough (16%), and general-fever and chills (16%). The common diagnoses were infectious (22% visits), genitourinary (12%), circulatory (10%), and endocrine (10%). Challenges identified were lack of clinical resources (57% of GPs), difficulties in communication (48%) and excessive workload (33%). Most common requests were for information technology (78%) and HIV (46%) training.Conclusion: The profile of common symptoms and diagnoses indicated the competencies family physicians in the regions should have. This information will be used to develop an appropriate FM curriculum at AAU

These fraudulent medications can include products that contain either accurate or incorrect ingredients, lack proper labeling, have insufficient quantities of ingredients, and are packaged with counterfeit packaging. This unlawful activity has led to treatment failures, the development of antibiotic resistance, adverse effects, and even deaths. Hence, the objective of this study was to assess the knowledge, practice, and regulatory status of veterinary drug experts in the central Gondar zone of Ethiopia regarding counterfeit veterinary medications.Methods: From January 2023 to July 2023, a self-administered structured questionnaire was utilized to conduct a cross-sectional study in Central Gondar Zone, Ethiopia. The analysis of the data involved the application of descriptive and chi-square tests.Results: The study revealed that the majority of professionals possessed a work experience ranging from 5 to 9 years (23; 56.1%). Additionally, a total of 25 individuals (61.0%) who participated in the research had not undergone any kind of training. It was observed that a significant proportion of participants (82.9%) possessed knowledge about counterfeit veterinary drugs. Only about 63% and 36% of respondents had high knowledge and good practice concerning veterinary counterfeit drugs, respectively. Only 29.3% of participants have reported practices. Furthermore, a poor regulatory level of coordination was detected (85.4%). The study revealed a significant (χ 2 =7.6165; p = 0.022) disparity between the respondents’ practice levels and training. Respondents’ regulatory levels were also significantly associated (p < 0.05) with their sex (χ 2 = 13.34; p = 0.001) and work experience (χ 2 = 13.64; p = 0.033). The research findings also revealed a noteworthy correlation between practice and regulatory activity (χ 2 = 15.0463; p = 0.005).Conclusion: The study outlines the necessity of awareness initiatives, with a focus on the significance of veterinary experts’ knowledge, practice, and regulatory efforts in addressing the issue of counterfeit veterinary medications.Keywords: counterfeit veterinary drug, veterinary drug professionals, cross-sectional study, knowledge, practice, regulatory activity, central Gondar zone, Ethiopi
