Abstract: The studies presented in this dissertation were designed to investigate the performance of dromedary camels under improved management condition based on two sets of experiments conducted in the long dry season (September - December). The first set evaluated milk yield and chemical quality of camels milk grazing/browsing natural pasture only (Control) and supplemented with Low (0.25 kg./kg milk), Medium (0.5 kg/kg milk) and High (0.75 kg/kg milk) level of concentrate. The second set...
Abstract: Barley is one of the popular crops cultivated since ancient time in the world. Food barley is one of the main cereal crops produced in Ethiopia. In Gurawa district, the productivity of food barley is low due to poor agronomic practices. Most of the farmers in this area do not use fertilizer except few other who use below the optimum rate. The unsuitable NPS fertilizer applications rate is also among the most important agronomic factors that hindered productivity of food barley arou...
Abstract: The effect of feeding different levels of baker’s yeast on feed intake, daily body weight gain (ADG), feed conversion ratio (FCR), blood constituents, carcass characteristics and profitability of the rations of Cobb 500 broiler chicks was studied. Four nearly isocaloric and isonitrogenous starter and finisher rations were prepared according to the recommendation of National Research Council (NRC). Unsexed 240 Cobb 500 chicks with an average initial body weight of 42.75±0.71g wer...
Abstract: A field experiment was conducted inBabile District during the main cropping season of 2019 to evaluate the effect of plant spacing (inter- and intra-row spacing) on yield and yield related traits of sorghum (Sorghum bicolor(L.)Moench].Four inter-row spacing (65 cm,75 cm,80 cm and 90cm) and four intra-row spacing (15, 20, 25 and 30 cm ) were evaluated as treatments using a randomized complete block design with three replications. Yield and yield related parameterswere collected and ...
Abstract: Low soil fertility and poor crop management practices including use inappropriate seeds rates are among the major constraints limiting the productivity of tef in Ethiopia in general and in the study area in particular. Thus, field experiment was conducted to assess the effect of rates of seed and blended fertilizer (NPSB) on growth, yield components and yield of tef and to identify economically feasible rates of seed and blended NPSB in the study area. Factorial combination of thre...
Abstract: One of the basic agronomic practices to improve the yield potential of common bean is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the yield and yield components of common bean using variety Dursitu (DOR-811) at Chiro District in eastern Ethiopia. The treatment consisted of four inter- row (20, 30, 40 and 50cm) and four intra- row (5, 10, 15 and 20 cm) spacing arranged in factorial combinati...
Abstract: This dissertation is composed of three separate experiments. The first and second studies evaluated the performance of broilers and white leghorn layers fed different levels of enset corm replacing maize grain. The third experiment assessed the performance of white leghorn layers fed kocho diets replacing maize. In the studies with enset corm treatments were ration consisting 0 (T1), 15 (T2), 30 (T), and 45% (T4) of enset corm as a replacement for maize by weight. In the experiment...
Abstract: Maize is one of the most important food crops grown in Oromia region of Ethiopia and is produced in different agro-ecologies in the region. However, its productivity is constrained by a number of problems. Among the several constraints in maize production, application of different blended NPS rates and planting space are the most important ones. A field experiment was conducted at Gamta Hamuma Kebele in Nedjo District, West Wollega Zone, western Ethiopia to assess the effects of ap...
Abstract: A study conducted at Haramaya University dairy farm aimed to evaluate the levels of macro and micro minerals in the feed, serum, and milk of lactating dairy cows. The 6 feed samples were collected from dairy farms and 22 milk and blood samples from cows selected based on parity (three to four) and stages of lactation (4 post-partum, 6 early, 6 mid, and 6 late). The analysis included measuring Calcium (Ca), Phosphorus (P), Potassium (K), Sodium (N), Magnesium (Mg), Zinc (Zn), and Ir...
Abstract: The study was conducted in Meta Distirict of Eastern Hararge Zone Oromia Regional State, with the aimed to assess general milk production and marketing, to determine chemical composition and microbial quality of raw cow's milk. Three kebeles namely; Biftu Ganama, Oda Chafe and Waligalte Bali'na were purposively selected based on their dairy potential. A total of 132 respondents were randomly selected from farmers (122),from consumers (6) and from collection centers (4). Interviewed...
Abstract: Common bean (Phaseolus vulgaris L.) is highly preferred by Ethiopian farmers because of its fast maturing characteristics that enable households to get cash income required to purchase food and household needs when other crops have not yet matured. However, the current national average yield of common bean is far less than the attainable yield under good management conditions for most improved varieties. This low yield of common bean in Ethiopia is attributed to several production ...
Abstract: The study was conducted in Arsi Negelle and Adami Tulu Jido Kombolcha (ATJK) districts from July to the end of September 2017, with the objectives to determine the effect of applying different sources of fertilizer on species composition, herbage yield and chemical composition of natural pastures and soil fertility status of pasture land. The experiment involved five treatments, i.e., (T1) control (no fertilizer application), (T2), a combination of urea and DAP (50 + 100 kg ha-1 re...
Abstract: Maize production plays vital role for the producers of the study area in serving as staple food. However, its productivity is constrained by a number of factors out of which optimum spacing is among the most important production factors. The Objective of the experiment was to investigate the influence of inter and intra-row spacing on yield components and grain yield of maize in 2019 cropping season at Chinaksen, East Hararghe Zone, eastern Ethiopia. The experiment was arranged in ...
Abstract: A study was conducted to evaluate the effect of substituting maize with different levels of sweet potato tuber meal (SWPTM) on feed intake, weight gain, and feed conversion ratio (FCR) and mortality percentage of broiler chicks. One hundred ninety two Cobb 500 broiler chick strains with initial weight of 35.64±0.37 (mean± SD) grams were randomly distributed to four treatments each with three replications in a completely randomized design. At the end of the trial, three broilers w...
Abstract: An experiment was conducted to evaluate feed intake, digestibility, body weight gain and carcass characteristics of Arsi Bale sheep fed a basal diet of wheat straw (WS) supplemented with crushed maize (CM) grain only or with graded levels of dried green Vernonia amygdalina (VA) leaves. Twenty male Arsi Bale sheep with mean initial live weight of 19.36±0.82 kg (mean ± SD) were grouped into five blocks based on initial body weight and randomly assigned to one of the four treatments...
