Feed Resources Gozamen District, East Gojjam Zone, Amhara Region

Ethiopia is the largest livestock producer in Africa, with 70.79 million heads of cattle, 28.48 million sheep, 25.91 million goats, 24.56 million donkeys, 11.39 million horses, 8.08 million mules, 8.39 million camels, and 42.51 million poultry. The largest livestock were found in Oromiya, Amhara and South Nations and Nationalities of People regions. However, the production of livestock is low due to technical constraints to livestock development like absence of approved livestock policy, lack of rural infrastructure and services, inadequate specialists and skilled staff, feed constraints, prevalent animal diseases, grazing land shortage, lack of credit, poor management, low genetic quality of most indigenous breed, recurrent drought, and lack of technical skill on feeding.

Feed Resources Gozamen DistrictFeed problem is one of the major factors that hinders the development and expansion of livestock production in Ethiopia. Natural grazing land is the predominant feed sources for livestock in lowland and crop residues represent a large proportion of feed resource in mixed crop livestock system of Ethiopia.

Effect of Climate Changes on Surviving of Nitzschia inconspicua Grunow



The climate is changing at a rate never seen before. Aquatic organisms are endangered throughout the world for various reasons, including global climate change. Changes in precipitation and temperature will dramatically affect the survival of many species. Plants play a key role in moderating climate change becausethey take up carbon dioxide (CO2). If plants are lost, the carbon (as CO2) will continue accumulating in our atmosphere and causes air temperature to rise, leading to ocean acidification. With climate changes, aquatic environments face increases in oceans salinity and sea level rise due to melting of the ice in the poles. These combined factors result in drastic world destruction. 

Nitzschia inconspicua Grunow

Organisms need specific conditions in order to survive. Scientists predict that these conditions will be altered when the global climate changes. A change insalinity and temperature could lead to death, migration, or poor health of the living organisms. The loss of aquatic environments will be a major disasterthat will take place because of previous changes

Evaluation of Biofield Treatment on Physical and Thermal Characteristics of Selenium Powder



The importance of selenium (Se) in human is well established, and its deficiency has caused serious diseases such as cancer and heart disease. Around 25 selenoproteins contain selenium as important element, which are commonly known as selenocysteine. In addition, research on selenium has gained significant attention due to its important role in antioxidant selenoproteins for protection against oxidative stress initiated by excess reactive nitrogen species (RNS) and reactive oxygen species (ROS). In selenocysteins, selenium metal functions as redox centre in various processes, which includes thereduction of nucleotides in DNA synthesis through selenoenzyme and thioredoxinreductase; and production of active thyroid hormone pre-cursor from selenium-dependent iodothyronine deiodinases. 

Selenium Powder

Furthermore, the bioavailability of selenium plays a crucial role in its anticancer and antioxidant activities. It is reported that the particles with crystallite size of nanometre range exhibit better bioavailability and low toxicity as compared to particles withlarge crystallite size. After considering the vast importance of selenium as nutrient in human body, authors wish to investigate an economically safe approach that could be beneficial to modify the physical and thermal properties of selenium powder.
