Effects Of Banana Peels On Chicken Weight Gain And Egg Production In The Urban And Peri-Urban Areas Of Aksum City, Ethiopia, H. G. Araya, S. G. Gebrekristos, W. V. Oliver

International Grassland Congress Proceedings

High feed cost of running urban-animal-agriculture and huge city wastes are challenges of the growing towns in modern Ethiopia. Egg production microenterprise is steadily growing due to its low initial investment and ready market in urban and peri-urban areas. However, cost of egg production is high due to the rising cost of corn, the main feed ingredient in poultry rations. Using banana peels, which forms a great proportion of city waste in Ethiopia, is seen as a way of not only reducing the waste, but also as an alternative low-cost feed supplement that could help enhance egg production by small-holder ...

Drylands cover 40% of the global land area and host 2 billion people, of which 90% live in low- or middleincome countries. Drylands often face severe land degradation, low agricultural productivity, rapid population growth, widespread poverty, and poor health. Governance structures and institutions are often eroded. Livestock-based livelihoods, largely depending on seasonal migration are common. Pastoralist communities and their land are highly vulnerable to climate shocks, while there are also changes in land tenure, insecurity/conflicts and rapid infrastructure development. Drylands Transform is an interdisciplinary research project revolving around the UN Sustainable Development Goals (SDGs). The project aim is to ...

Range Condition Classification Based On Quantitative Characteristics Of Vegetation, Nafiseh Fakhar, Mansour Mesdaghi, Kamal Naseri

International Grassland Congress Proceedings

Change in range condition classes over time are usually the basis for monitoring management effectiveness. Several approaches have been proposed to monitor the range condition classes in relation to a bench mark usually called climax stage. There are some types of range condition classification often included in a range inventory. In this paper, six factors of canopy cover, litter frequency, plant vigour, soil protection percentage, plant composition, and present production as a percentage of indicative state were described for determination range conditions. We have determined range condition classes by using R software. This method was developed by FAO projects in ...

Despite expert consensus and evidence-based preventative strategies against drowning, limited formal study exists on translating recommendations into practical and effective interventions. This paper describes the design of an education-based drowning prevention intervention and reports results from a pilot evaluation of the program’s effect on self-reported water-safe behaviors, attitudes, self-efficacy, and knowledge. Parents and caregivers attending children’s swim lessons in July and August 2018 participated in a brief water-safety education program. A pre-post-test design evaluated "Theory of Planned Behavior" indicators to assess for changes. We found significant increases in scores related to water safety knowledge, attitudes on maintaining arms ...


Mechanisms Of Diapause And Cold Tolerance In The Colorado Potato Beetle, Jacqueline E. Lebenzon 2022 The University of Western Ontario

Mechanisms Of Diapause And Cold Tolerance In The Colorado Potato Beetle, Jacqueline E. Lebenzon

Electronic Thesis and Dissertation Repository

Many temperate insects enter diapause (a state of dormancy) and enhance their cold tolerance to survive the winter. During diapause, the Colorado potato beetle (CPB, Leptinotarsa decemlineata, Coleoptera: Chrysomelidae) stops developing, lowers its metabolism, and changes its physiology to avoid freezing. The extent to which diapause confers cold tolerance in CPB is currently unknown. In my thesis, I used CPB to improve our understanding of the mechanisms underlying metabolic suppression during diapause and cellular protection at sub-zero temperatures in insects. First, I used RNA-sequencing (RNA-seq) to compare gene expression in two metabolically important tissues (the fat body and flight muscle ...

International Grassland Congress Proceedings

Alfalfa cultivation in South Korea is not common. There are many reasons, but low productivity has been extremely limited. Although alfalfa growth was poor due to boron deficiency in the soil, the problem has recently been solved. Nevertheless, the cultivation of alfalfa is not expanding. About 200,000 tonnes of alfalfa hay are imported every year. Therefore, this study was conducted to find a way to replace imported hay by expanding alfalfa cultivation in Korea. Alfalfa (P5444) was sown in northern part of South Korea (Pyeongchang). Alfalfa was sown in September 2018 with different seeding rates (20, 30 and 40 ...

Effect Of Prompt-Delayed Packaging And Ensiling Time On Fermentation And Aerobic Stability Of Soybean Curd Residue, Ajmal Wali, Takeshi Tsuruta, Naoki Nishino

International Grassland Congress Proceedings

Wet soybean curd residue (SCR) obtained from two tofu factories (F1 and F2) was anaerobically stored with or without added beet pulp (BP). Sealing was performed on the day of tofu production (prompt sealing [PS]) or 2 days after SCR was piled and unprocessed (delayed sealing [DS]). Predominant lactic acid fermentation was observed regardless of the sealing time and BP addition. Acinetobacter spp. were the most abundant (> 67%) bacteria in pre-ensiled SCR, regardless of the factory and sealing time. In PS silage, the abundances of typical lactic acid-producing bacteria, such as Lactobacillus, Pediococcus, and Streptococcus spp. reached > 50%. In DS ...

Relationship Between Exchangeable Acidity And Persistence Of Orchardgrass (Dactylis Glomerata) In Temperate Pastures Under Different Management, H. Kakihara, S. Ogura

International Grassland Congress Proceedings

Orchardgrass is a high productive, highly nutritive grass, but its persistence is low under acid soil condition. Therefore, to obtain the information on the effect of soil acidity on the persistence of orchardgrass in acid soil grasslands, we investigated the relationship between exchangeable acidity (y1) and orchardgrass in sown pastures. Eight temperate pastures (four cutting meadows [CMs] and four cattle grazing pastures [GPs]) were used for vegetation survey and soil samplings. Six or three line transects (50 m each) were fixed in each meadow or pasture, and measurement location (three quadrats 20 cm×20 cm in size and 50 ...

International Grassland Congress Proceedings

Vast areas of tropical forest have been converted into pastures sown with introduced grasses (Urochloa spp.). The majority of pastures exist in some stage of degradation, which has dramatic ecological and economic consequences. Our objective was to determine isotopic 15N signature of grass alone and grass-legume pastures to estimate sources of nitrogen (N) to grasses in farmer managed pastures. This work contributes to enhancing the sustainability of tropical pastures in forest margins through the integration of legumes. The overarching hypothesis tested was that legumes associated with grasses will improve nutrient supply via symbiotic fixation and mobilization of soil phosphorus ...


Landscape-Level Impacts Of Mesquite Canopy Cover On Herbaceous Species Composition, D. B. Murray, C. E. Cooper 2022 Tarleton State University

Landscape-Level Impacts Of Mesquite Canopy Cover On Herbaceous Species Composition, D. B. Murray, C. E. Cooper

International Grassland Congress Proceedings

Woody encroachment of mesquite (Prosopis) and acacia (Acacia) species into grasslands has widespread and ongoing impacts on grassland ecosystems. Changes in the herbaceous layer are associated with changes in the canopy cover of these sparse-canopied species, which do not exclude the herbaceous component, but often change species composition under the canopy relative to surrounding open areas. These effects are often differential based on productivity of the site and herbaceous species composition of the grassland. Here we investigated landscape-scale changes in the herbaceous composition resulting from changes in canopy cover of honey mesquite (Prosopis glandulosa) within woody-encroached areas of Texas, U ...

Interactive Effects Of Drought And Fire On Co-Existing Woody And Herbaceous Communities In A Temperate Mesic Grassland, R. Keen, J. Nippert, E. Tooley, K. O’Keefe, S. Bachle, M. Sandwick

International Grassland Congress Proceedings

Increased drought and woody encroachment are likely to have substantial and interactive effects on grassland carbon and water cycling in the future. However, we currently lack necessary information to accurately predict grassland responses to drought-by-fire interactions in areas experiencing woody encroachment. A more thorough understanding of these interactive effects on grass-shrub physiology would improve the effectiveness of demographic vegetation models and refine predictions of future changes in grassland ecosystem function. To this end, we constructed passive rainout shelters over mature Cornus drummondii shrubs and co-existing grasses in two fire treatments (1-year and 4-year burn frequency) at the Konza Prairie Biological ...

Interacting Effects Of Disease And Weather Variability On Rangeland Biodiversity Associated With Black-Tailed Prairie Dog (Cynomys Ludovicianus) Colonies, Courtney J. Duchardt, J. D. Hennig, D. Pellatz

International Grassland Congress Proceedings

Rangeland ecosystems worldwide are experiencing novel pressures during the Anthropocene, including land conversion, disease dynamics, non-native species, and climate change. These issues can be compounded in rangelands occupied by burrowing rodents. Often considered keystone species important for maintaining rangeland biodiversity, these species often experience widespread control efforts because of their potential to reduce forage for livestock. We examined the effects of climatic variation and disease on bird communities associated with a North American burrowing rodent, the black-tailed prairie dog (Cynomys ludovicianus). Following an outbreak of sylvatic plague (Yersinia pestis) in the prairie dog population, we observed rapid shifts in taxa ...
