Treatments...
Abstract: An experiment was conducted to evaluate the effects of supplementing Moringa stenopetala leaf mea l(MSLM) on feed intake, growth performance and carcass characteristics of cobb 500 Chicken at Haramaya university poultry farm. A total of 192 Cobb 500 day-old broiler chicks with initial body weight of 36.23±0.25 (Mean±SD) gram were randomly 16 chicks per replicate distributed into 12 pens, representing 4 treatment diets each replicated three times. The experiment lasted for 45 days...
Abstract: A study was conducted with the objective of evaluating the effect of feeding different proportions of dry pigeon pea and neem leaves on feed intake, digestibility, body weight gain and carcass parameters of Gumuz goats. Thirty six yearling intact male Gumuz goats with initial mean body weight of 14.1 ± 1.5 kg (mean ± SD) were used for the experiment. The experimental design used for all parameters was randomized complete block design. The experimental animals were grouped in to s...
Abstract: The study was conducted at Agarfa ATVET College with the Objectives to investigate the effect of cafeteria leftover (DCLO) replacement for concentrate mix (CM) on feed intake, nutrient digestibility, feed conversion efficiency, daily body weight gain and carcass yield of Arsi – Bale sheep and economic benefit of replacement of cafeteria leftover for concentrate mix. The experiment consisted of 90 days of feeding trial and seven days of digestibility trial followed by evaluation o...
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: 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: 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 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: Fish feed protein ingredients are the most expensive and often unavailable in subSaharan Africa especially in commercial aquaculture systems. The major fish feed protein ingredient in fish farming in Kenya is fishmeal (FM) that is often times expensive and adulterated leading to low productivity of fish farming. This problem has necessitated a need for exploring alternative less expensive and easily available protein sources such as black soldier fly larvae (BSFL). This study aimed...
Abstract: Increasing demand for soybean meal and fishmeal for use in formulating animal feeds has led to increased prices and moreover their availability in future might be limited. Insect rearing can be part of the solution because they take a short period to mature, require small space and fewer resources to start. This study was designed to evaluate the effect of substituting fishmeal (FM)with black soldier fly larvae (BSFLM) at different inclusion levels, as a protein source in exotic ch...
