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: The study was conducted at Bako Agricultural Research Center with the aim to evaluate the effects of Elephant grass ensiled with different proportion of Dolichos lablab on intake, digestibility, body weight gain and carcass parameters. Elephant grass was harvested after eight weeks of regrowth during rainy season and Dolichos lablab harvested at 50% blooming stage and both forages were chopped and weighed separately, mixed, added with 3% molasses and ensiled in pit. A total of twen...
Abstract: The study was conducted in Selected Districts of Sidama zone with the objective to assess the production practices, productive and reproductive performance, on farm evaluation of milk production performance, and chemical composition of milk of Local cows, and to identify their constraints and opportunities. For study, multistage sampling was employed in that three districts were selected representing Highland (Wonisho), Midland (Dale) and Lowland (Loka Abaya) from Sidama Zone and t...
Abstract: Four interrelated studies were conducted to assess milk handling practices, microbiological quality and safety of raw cow milk across the milk supply chain in eastern Ethiopia. The first study evaluated hygienic cow milk production practices of producers, while the second study assessed milk postharvest handling practices of producers, collectors/transporters, vendors and consumers across the milk supply chain in the study area. Both studies employed cross sectional survey. The stu...
Abstract: The experiment was conducted at Yabello Pastoral and Dry land Agriculture Research Center with the objectives to evaluate the effect of supplementation of browse species mixed with wheat bran on feed intakes, digestibility, growth performance and carcass characteristics of Borena goats fed a basal diet of native pasture hay, and to identify the economic feasibility. The experiment was conducted using Twenty five (25) intact male yearling Borena goats with an average live weight of ...
Abstract: Livestock production and tanneries have high potential in Ethiopia, even though there are a critical shortage of quality raw hides and skins at national level. In the study districts there is high livestock population potential for hide and skin production but different types of defects were observed and hampered the effective and efficient utilization of these resources. Therefore, cross- sectional study was conducted in Bako Tibe and Ilu Gelan districts, West Showa zone, Oromia R...
Abstract: An experiment was conducted in Horro Guduru Zone, at Guduru Animal Production and Research Center (GAPRC) of Wollega University to evaluate the effect of Ficus sur (Cv. Forssk) fruits supplementation on feed intake, milk yield and composition, and sensory attributes of Horro cows. Twelve healthy lactating Horro cows of similar lactation stage, body weight and condition were selected from GAPRC. All of the selected cows were in early (one weak to 10days) lactation stage. The experim...
Abstract: The study was conducted to assess the availability of feed resources, major constraints of ruminant production, identify the major indigenous browse species (IBS) in the area, characterizing their local utilization, chemical composition, degradability and biomass yield in two agro-ecologies (Midland and highland)in the eastern zone of Tigray in northern Ethiopia. A semi structured questionnaire was used at community and household levels and a total of 270 respondents (180 from high...
Abstract: The study was conducted in Bedano district, East Hararghe Zone of Oromia Region, Ethiopia. To assess milk production, reproduction, handling, marketing system and analyze milk composition of local cows at smallholder farmers’. The study had two parts: survey and monitoring. For survey study Multi-stage stratified sampling technique was employed to select targets. The number of PAs selected from rural, 3 PAs (About 10% of these PAs) was selected by using purposive sampling and for...
Abstract: The study was assessed smallholder chicken production practices and locally available feed resources. Six kebeles from two districts and 30 households (HHs) from each 6 kebeles were selected purposively and stratified to local, exotic, and mixed breed keepers. Four locally used ration samples were identified, collected and analyzed at Haramaya University Animal nutrition laboratory. The average flock size was highest in mixed breed (16.6 chickens) rearing strata. Purchase (36.1%), ...

Abstract: Improvement of the contribution of the untapped huge goat resource of Ethiopia can be achieved through alleviating constraints and adjusting inefficient production practices which requires knowledge about roles of goat, husbandry practices, production constraints, performance under the prevailing condition and available resources. With this understanding, a survey study on goat production systems of mixed crop livestock (MCL) and Agro pastoral (AP) Farming systems in the rural kebe...
Abstract: A survey and other three interrelated trials were conducted on the objective of selecting the best maize form that would substitute brewery grain in crossbred (Fogera and Holstein Friesian) dairy cows ration. In the survey (paper I) a cross-sectional single visit multi-purpose design was used to assess farmers’ perception, and available practices for hydroponic fodder production. In paper II and III, a 4 x 3 factorial experiment (four maize varieties with three seed rates) in a C...
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--- 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...
