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 experiment was conducted in Haramaya University beef farm from July 2019- June 2020 with the objective to investigate milk production, milk composition and calve growth performance(birth weight,weaning weight and daily weight gain) of ogaden cattle under improved feeding management. Sixteen lactating cows from early to late lactation stage were used by Randomized complete block design to receive four treatment diets. The supplementation was given based on cow’s daily milk yie...
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: A study was conducted to evaluate the effect of substituting maize with different levels of taro tuber meal (TTM) on feed intake, weight change, feed conversion ratio, mortality percentage, carcass characteristics and partial budget analysis of broiler birds. Four experimental diets were formulated with T1 (control) containing 0% TTM while diets T2, T3 and T4 contained (TTM) each at 20%, 40% and 60% replacement levels respectively. Two hundred sixteen unsexed blood Cobb 500 broiler...
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: A study was conducted to evaluate the efficacy of oral administering neem and bitter leaf extract as natural feed additive for broiler chicks on feed Intake, body weight gain, feed conversion ratio (FCR), carcass parameters, hematological serum biochemical parameters, chick mortality percentage, sensory evaluation of meat, chemical composition of meat and partial budget analysis of broiler chicks. Unsexed one hundred ninety-two, day-old Cobb 500 broiler chick with initial weight of...
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: A study was conducted to assess forage mass, botanical composition, nutritive value of herbaceous vegetation, grazing behavior, forage selectivity and performance of co-grazing sheep, goats, cattle and camels with initial body weights (BW) of 20.6±2.09, 16.6±0.97, 96.8±3.43 and 162.3±21.28 kg, respectively. Grazing lasted 16 weeks, using 6 growing animals from each animal species (AS). Animals co-grazed 6 ha of grazing area (G) with diverse plant species. Four enclosures (E) ea...
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...
