Abstract: The study was conducted to evaluate the effect of genotype, age at slaughter, aging temperatu re and aging duration on meat toughning of beef produced from Arsi, Borena, Harar and cro ss of Holstein Friesian with Arsi cattle breeds. A total of 24 bulls from Arsi (6), Borana (6), Harar (6) and crossbreed of HF breeds (6) were used for this study. The bulls were stratified into two age groups 2 - 3 and 4 - 5 years. Temperature and pH were recorded at 45 min, 3, 6, 12 and 24 hours on ...
Abstract: The study was based on two experiments;Experiment Iused white leghorn layers (Paper I and Paper II) whereasExperiment IIused cobb500 broilers (Paper III and Paper IV). Experiment-I was conducted to study effect of replacing soybean meal (SBM)with graded levels of linseed meal (LSM) on feed intake, egg production and quality, fertility, hatchability and chick quality(Paper I) and egg chemical compositions, fatty acids profiles and eating quality (Paper II). Experiment-II studied fee...
Abstract: The general objectives of the study were to provide information necessary for the development of appropriate management strategies to ensure improved quality of drinking water for livestock and to determine the extent to which consuming saline water affects performance and health of sheep and goats. Specific objectives were to analyze the quality of water from rift valley lakes of Ethiopia for livestock drinking and to determine the effects of salinity of drinking water on performa...

Abstract: A study was conducted to evaluate the effect of feeding kocho waste,“dupo” (scraped pseudostem fermented in a pit as upper cover of whole kocho) as a substitution of energy portion of concentrate mixture (ECM, that is 2:1 ratio of maize and wheat bran) on feed intake, digestibility, live weight gain, carcass characteristics, meat quality and economic benefit of Harerge Highland sheep fed a basal diet of natural grass hay. Twenty-four yearling intact Harerge highland sheep with ...
Abstract: Potato is an important tuberous vegetable crop in Ethiopia. It is production is constrained by arthropod pests, nutrient depletion of soil and diseases. Among the arthropod pests, two-spotted spider mite (TSSM) is one of the major pests affecting potato production in eastern Hararghe, Ethiopia. To tackle this problem, the survey was undertaken to assess the status of TSSM on the irrigated potato. The data were collected from ninety-six potato producers from October to March in Hara...
Abstract: Cotton flea beetle, Podagrica puncticollis Weise is among the most chronic and economically damaging insect pests of cotton in Northwestern Ethiopia. Although this beetle is known to cause significant crop losses, the ecological aspects and management of this insect pest have not been adequately assessed and documented. Thus, five studies were conducted in the area. The first study was conducted in Metema district to assess the cotton growers’ perception and knowledge of cotton f...
Abstract: Value chain analysis of maize in Nedjo woreda has been conducted to identify value chain actors, and their roles and linkages, to analyze maize marketing costs and margins of different actors along the value chain, and to identify factors affecting marketed surplus of maize at producers’ level. To accomplish these tasks, both primary and secondary sources of data were used. Data have been collected from randomly selected 119 maize producer households in Nedjo woreda using a semi-...
Abstract: The study was conducted in Plant Protection Laboratory and greenhouse (GH) at Haramaya University under 25±2 oC, 70±5% RH and 30±2 oC, 60±5% RH, respectively, during 2016. The objectives were to: 1) evaluate the efficacy of some pesticides on Tetranychus urticae in the laboratory and greenhouse; and 2) evaluate the performance of TSSM to six plants under GH conditions. The efficacy of five pesticides, viz. Amitraz, Profenofos, Chlorantrniliprole + λ-cyhalothrin, and Profenofos...
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...
