However, these contents can vary with the species of bee and at different value chains. Thus, this study aimed to investigate the bioactive components, antioxidant, and antibacterial activities of honey produced from Apis mellifera and Meliponula beccarii honey along the value chain. 2024-05-01T00:00:00Z https://repository.ju.edu.et//handle/123456789/9847 Effects of fertilizer types and harvesting stages onagronomic performance, biomass yield, chemicalcompositions, and in vitro digestibility of rhodesgrass (Chloris Gayana K.) At mizan, south west ethiopia Tamiru hailu; Wasihun hassen; Abdo mohammed The field experiment was conducted to determine the effects of fertilizer types and harvesting stages on agronomic performance, forage biomass yield, chemical composition, and in vitro dry matter digestibility of Rhodes grass (Chloris Gayana K) during the 2023 growing season in Mizan, Ethiopia under rain condition. A factorial arrangement with four fertilizer types (control, NPS, farmyard manure, and NPS + manure) and three harvesting stages (60, 90, and 120) with three replications was used. The data collected were morphological characteristics such as plant height, number of tillers per plant 2024-06-01T00:00:00Z https://repository.ju.edu.et//handle/123456789/9753 Effect of intercropping oats (Avena sativa L.) With alfalfa (medicago Sativa) on dry matter yield, nutritive value, in vitro ruminal Fermentation kinetics and silage quality Daniel Wana; Aregaw Abera; Wamatu Jane There is limited information on planting density for oats and alfalfa when intercropped to achieve a mixture of high nutritional quality for use as animal feed. A field experiment was carried out to study the effect of seeding ratio on yield components (TDM and seed yield), chemical composition (CP, OM, NDF, ADF, ADL, and Ash), total gas, CH4 and SCFA, silage (physical and chemical properties), and soil chemical composition (PH, OC, OM, EC, CEC, TN, K, and P). The experiment was conducted at the Adami Tulu Agricultural Research Center under irrigation conditions during February–June 2022/2023 in Oromia Regional State, Ethiopia. Treatments consisted of one adapted oats (bate) variety and one alfalfa (magna 788) variety in an additive design at three plant densities (25%, 50%, and 75% of their recommended sole seed rates of 80 and 15 kg per hectare for oats and alfalfa, respectively) and the recommended 100% plant density of sole oats and sole alfalfa. 2024-06-01T00:00:00Z https://repository.ju.edu.et//handle/123456789/9714 Agronomic Performances and Nutritional Values of Varying Levels of Row and Treated Amaranth Grain Meal in Broilers and Layers Rations Waseyehon Assen; Solomon Demeke; Taye Tolemariam The worldwide scarcity of high-quality feed highlights the critical need to investigate alternative feed sources, such as amaranth, to satisfy the nutritional requirements of poultry. Amaranth is recognized for its potential as a protein and carbohydrate supplement in chicken diets; however, research on locally cultivated varieties, particularly in the Jimma zone of Ethiopia, remains limited. This PhD study was aimed to assess the use of amaranth as a poultry feed ingredient by examining its agronomic performance, nutritional profile, and effects on both broiler and layer chicken production 2025-04-01T00:00:00Z
