Abstract: This study was conducted in Zone 2, Afar National Regional State to assess the beekeeping production system and evaluate the major honey quality parameters in different seasons and in different districts of the study area. For these study four districts and from each district four kebeles were selected using purposive sampling methods. A total of 100 beekeepers with different proportion from each kebele were selected randomly. Beekeepers were interviewed using pre-tested semi struc...
Abstract: This study was conducted to evaluate the effects of deep-litter and cage housing systems on laying performance, egg quality, hematological parameters, and serum metabolites of White Leghorn layers at Haramaya University. A total of 120 White Leghorn layers at an age of 26 weeks and an average initial body weight of 1246.25± 5.65g were randomly assigned to the two housing systems in completely randomized design with three replications for study period of 90 days. The chickens were ...
Abstract: Potato is an important food and cash crop in eastern Ethiopia including Oda Bultum District of West Hararghe Zone. However, there is no information on the role of blended NPSB fertilizer required to produce tuber yield and tuber quality traits of potato varieties in Oda Bultum District. A field experiment was conducted in Oda Bultum District, under rainfed during 2018 cropping season, with the objectives of assessing the effects of blended NPSB fertilizer rates on yield-related tra...
Abstract: Nitrogen and phosphorus deficiency are the most important production constraint of maize next to moisture deficiency. Therefore, a field experiment was conducted at Haramaya University main campus research station (Rare), eastern Ethiopia, using a maize hybrid xv variety (BH 661) as a test crop in the 2015 cropping season. The objectives of the study were to investigate the effects of nitrogen and phosphorus fertilizer application on growth, yield components and yield of the maize ...
Abstract: Calves are the foundation of the future dairy herd which signifies the importance of their proper rearing practices and needs to be performed at the herd and individual animal. This study was therefore conducted to assess calf husbandry practices in the urban dairy production system and to evaluate the effect of milk replacers on crossbred calf’s performance. The assessment was conducted in Dire Dawa city which was purposively selected based on its potential for dairy production....
Abstract: Nitrogen fertilizer is a major input required for cereal crop production in Ethiopia and its efficient use is important for the economic sustainability of cropping systems. Furthermore, the dynamic nature of N and its susceptibility for loss from soil-plant systems creates a unique and challenging environment for its efficient management especially on Vertisols. Developing suitable nitrogen fertilizer management practices is important strategy to improve productivity, quality and n...
Abstract: A study was conducted to evaluate the effect of dietary inclusion of mango seed kernel on growth performances (feed intake, body weight gain), feed conversion ratio, carcass characteristics, mortality percentages and partial budget analysis of broiler chicks at various levels of Mango Seed Kernel (MSK) as energy supplement at Haramaya University poultry farm.168 broiler chicks with average body weight 45.17±1.08g/b/d (mean ±SD) were randomly distributed to four treatments each wi...
ABSTRACT--- This experiment was carried out to determine the performance and carcass quality of broilers placed on pro-vitamin A cassava and sweet cassava-based diets using maize-based diet as control. The results show that daily weight gain of birds placed on maize-based diet (19.67g) was statistically higher (p0.05) among themselves. The average daily feed intake of the maize- based diets (54.07g/day) was significantly higher (p0.05) between each other. The feed conversion ratio of 2.75...
Abstract: Environmental friendly pre-treatment of fibre has been lately adopted by many researchers worldwide but not fully understood. Although various chemical modifications of fibre through several chemical treatments have been explored, but less has been done on lower sodium hydroxide (NaOH) concentrations. This paper investigated the effect of thermalization at 115 C and lower NaOH of concentrations (1, 3 and 5) effect on mukwa wood flour as a way of minimizing chemical impact on possib...
Abstract: Termite mounds are replete with natural nanoparticles, and they vary in physicochemical, geochemical, mineralogical, and biological properties from the adjoining soils. Although termite mounds have wide ecological and environmental roles including soil formation, faunal and vegetation growth and diversity, organic matter decomposition, geochemical exploration, water survey, treatment of underground contamination, thermoregulation, gas exchange, and global climate change, their nano...
Abstract: Advancement of knowledge on soil microbial richness is a key to environmental policy and sustainable land management. In Botswana, there is a dearth of scientific reports on soil bacterial dynamics. The aim of this study is to improve our understanding of how soil physico-chemical properties influence bacterial abundance and distribution under different land-use types (ecosystems). Six ecosystems studied include saline soil, sewage sludge dump, garden, fallow land rainfed and irrig...
Abstract: Diversifying tourism products is a vital contemporary business strategy for maintaining a competitive advantage in the face of rapid technological, economic and social changes. Tourism in Botswana is largely dependent on wildlife and international tourists and consistent calls to diversify over the past four decades have greatly been amplified by the colossal impact of the COVID-19 pandemic. A semi-systematic literature review analyzed progress and research trends related to touris...
Abstract: This study sought to establish the extent to which people with disabilities (PWD) are employed in the hotel sector in Zimbabwe. The study was motivated by the continued emancipation of PWDs globally and industry’s increasing acceptance of the contributions PWDs can make. Using a qualitative approach (interviews with hotel managers), this study revealed that PWDs are not employed in Zimbabwe’s hotel sector. Stigma, lack of information/knowledge about disabilities, and supposed c...
Abstract: It is evident from literature that the spread of the Covid-19 pandemic has brought the world economies to its ‘knees’. No industry has gone untouched by the effects of this pandemic. Globally there has been an adverse impact on travel which is backbone of the hotel industry. This study focuses on exploring the impact that the Covid-19 pandemic has had on Zimbabwean hotel sector. The objectives of the study focused on investigating the impact of Covid-19 pandemic on hotel occupa...
Abstract: The study sought to determine tourist perceptions on the threats to the sustainability of wildlife tourism using a case study of two state protected areas in Zimbabwe. Using close-ended questionnaires, we collected data from 128 tourists in December 2015. Results show respondents generally perceived all the seven tested threats as serious, i.e., illegal hunting, destruction of wildlife habitats, human-wildlife conflict, lack of involvement of local people in national park touri...
