Abstract: The objective of this study was to compare the characteristics of exotic chickens' eggs and their crosses. For this, the qualities associated with egg quality were assessed in 240 eggs from each genotype, totaling 2400.Eggs' weight, length, width, albumen height, yolk height, albumen weight, yolk color, eggshell weight, and eggshell thickness were all measured. SAS was used to analyze the data, and a substantial difference was found. The Duncan Multiple Range Test was used to disti...
Abstract: Maize is becoming an important cereal crop in Ethiopia due to its use as sources of food security and generated income. However, its productivity is constrained by insufficient application of NPS fertilizer rate and different inter row spacing. Thus, afield experiment was conducted at Haramaya to assess the effects of application of different rates of blended NPS fertilizer and inter- row spacing on growth, yield components and yield of maize and to estimate the cost benefit analys...
Abstract: Groundnut (Arachis hypogaea L.) is one of the most important cash oil crops for smallholder farmers in semi-arid parts of eastern Ethiopia. However, its productivity is low due to biotic and abiotic stresses as well as poor agronomic practices. Suboptimal plant population and soil fertility depletion are among the major constraints to sustainable groundnut production in the semi-arid ecology of Ethiopia. This problem is aggravated by lack of application of fertilizers at appropriat...
Abstract: Bread wheat is one of the major crops in the study area cultivated both for home consumption and market purposes. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation. Therefore, field experiment was carried out to assess the effect of blended NPSB fertilizer rates on yield, and yield related traits on selected bread wheat cultivars during the 2018/2019 cropping season on farmer training center (FTC) in Ke...
Abstract: This study was conducted in Zone 2, Afar National Regional State to assess the beekeeping production system and evaluate the major honey quality parameters in different seasons and in different districts of the study area. For these study four districts and from each district four kebeles were selected using purposive sampling methods. A total of 100 beekeepers with different proportion from each kebele were selected randomly. Beekeepers were interviewed using pre-tested semi struc...
Abstract: This study was conducted to evaluate the effects of deep-litter and cage housing systems on laying performance, egg quality, hematological parameters, and serum metabolites of White Leghorn layers at Haramaya University. A total of 120 White Leghorn layers at an age of 26 weeks and an average initial body weight of 1246.25± 5.65g were randomly assigned to the two housing systems in completely randomized design with three replications for study period of 90 days. The chickens were ...
Abstract: Potato is an important food and cash crop in eastern Ethiopia including Oda Bultum District of West Hararghe Zone. However, there is no information on the role of blended NPSB fertilizer required to produce tuber yield and tuber quality traits of potato varieties in Oda Bultum District. A field experiment was conducted in Oda Bultum District, under rainfed during 2018 cropping season, with the objectives of assessing the effects of blended NPSB fertilizer rates on yield-related tra...
Abstract: Nitrogen and phosphorus deficiency are the most important production constraint of maize next to moisture deficiency. Therefore, a field experiment was conducted at Haramaya University main campus research station (Rare), eastern Ethiopia, using a maize hybrid xv variety (BH 661) as a test crop in the 2015 cropping season. The objectives of the study were to investigate the effects of nitrogen and phosphorus fertilizer application on growth, yield components and yield of the maize ...
Abstract: Calves are the foundation of the future dairy herd which signifies the importance of their proper rearing practices and needs to be performed at the herd and individual animal. This study was therefore conducted to assess calf husbandry practices in the urban dairy production system and to evaluate the effect of milk replacers on crossbred calf’s performance. The assessment was conducted in Dire Dawa city which was purposively selected based on its potential for dairy production....
Abstract: Nitrogen fertilizer is a major input required for cereal crop production in Ethiopia and its efficient use is important for the economic sustainability of cropping systems. Furthermore, the dynamic nature of N and its susceptibility for loss from soil-plant systems creates a unique and challenging environment for its efficient management especially on Vertisols. Developing suitable nitrogen fertilizer management practices is important strategy to improve productivity, quality and n...
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: Faba bean (Vicia faba L.) is an important legume grown in the highlands of Ethiopia. However, the yield of the crop is limited by a number of edaphic constraints out of which low soil fertility, low pH and reduced N2 fixation due to various biological and environmental factors are the major problem. Therefore, a field experiment was conducted at Bore Agricultural Research Center under rain-fed condition during the 2015 main cropping season to evaluate effects of Rhizobium inoculati...
Abstract: The study was conducted to investigate the effect of mixtures of Ruta Graveolen (Ruta chalepensis L.), coriander (Coriandrum sativum L.), and basil (Ocimum basilicum) seed extracts in drinking water on productive performance, some blood profiles, egg quality, egg chemical composition, and economic benefit of white leghorn at Haramaya University poultry farm for 8 weeks. One hundred eighty White Leghorns (WL) layer at twenty- six weeks of age were randomly distributed to four treatm...
Abstract: The present investigation was conducted to determine the impact of the dietary addition of garlic and ginger as natural feed additives on feed intake, productive performance, carcass characteristics, hematology and serum biochemistry, economic efficiency, and mortality of broilers. A total of one hundred and ninety-two day old, unsexed (cobb-500) broiler were randomly divided into four experimental groups with three replication per treatment which consisted 16 birds. The birds were...
