Abstract: Viral diseases are posing a growing threat to the young poultry industry flourishing in the country. Infectious bursal disease, Newcastle disease, Marek’s disease (MD), and Fowl pox are among the serious threats to poultry production. IBD is considered as AIDS of chicken since it severely affects the immune system of chicken. NDV is a human pathogen and the most common sign of infection in humans is conjunctivitis. Marek’s disease (MD) is a lymphomatous and neuropathic disease of domestic fowl. Avian pox is a viral disease of a wide range of both domestic and wild bird species. It is a slow-spreading and characterized by the formation of proliferative lesions and scabs on the skin, and diphtheritic lesions in the upper parts of the digestive and respiratory tracts. Many viral diseases of poultry can be diagnosed on the basis of clinical signs together with post mortem findings and histopathological changes. However, confirmation of the involvement of specific viral pathogens requires specific laboratory procedures. There is no specific treatment for viral diseases of poultry. However, antibiotics are sometimes given in viral disease outbreaks to prevent secondary infection with bacteria. The most practical way to control viral diseases in poultry and prevent losses through effective biosecurity practices, timely vaccination and good hygiene accompanied by improved management is therefore of the greatest importance at all times.

Abstract: The Northern Fergana river basins under study are located in the territory of the Republics of Uzbekistan and Kyrgyzstan, and are part of Fergana valley. The territory of the Northern Fergana is provided with many rivers comparing to other parts of Fergana valley. These rivers are so important for economic and agricultural activities. Because of land use/land cover change, there is an ever-increasing impact on the environment. The present paper analyzes the landscape-ecological situations of the largest river basins of the Northern Fergana (basins of Pochchaotasoy, Kasansay, Gavasay rivers). For this purpose, land use land cover changes of watersheds were calculated. The results show that anthropogenic activities play an important role in forming landscape-ecological situations of the watersheds.

ABSTRACT: Bovine fasciolosis is an economically important parasitic disease of cattle caused by Fasciolidaetrematodes of the genus Fasciola. The two most important species of this genus, Faciola hepatica and Faciolagigantica, are commonly known as liver flukes. The distribution of fasciolosis is worldwide, however, the distribution of Faciola hepatica, is limited to temperate areas and highlands of tropical and sub-tropical regions while Fasciolagigantica, which predominates in tropical area. The definitive hosts for Faciola hepatica are most mammals among which sheep and cattle are the most important once. The geographic distribution of trematode species is dependent on the distribution of suitable species of snails. Ethiopia has a high livestock population but productivity is low as a result of diseases, malnutrition and other management problems. Both Faciola hepatica and Faciolagigantica species of genus Faciola are found in Ethiopia and are transmitted by Lymnaea truncatula and Lymnae natalensis, respectively and various reports indicated that it is a serious problem of livestock production in Ethiopia causing considerable economic losses. Diagnosis based on clinical signs, seasonal occurrence and a previous history of fasciolosis. Fasciolosis causes a substantial economic loss which includes death, loss in carcass weight, reduction in milk yield, condemnation of affected liver, decline production and productive performances, exposure of animals to other diseases due to secondary complications.

Abstract: Transport and logistics education is critical for supporting economic growth and sustainable development in Nigeria and Namibia. However, these countries face challenges in providing quality and accessible education in this field. This article explores the potential of integrating libraries and digital science in promoting transport and logistics education in these countries. The article highlights the importance of transport and logistics education and the role of libraries and digital science in education. It discusses the current state of transport and logistics education in Nigeria and Namibia, as well as the integration challenges. The article also examines examples of successful integration of libraries and digital science in transport and logistics education in other countries. Finally, the article calls for action to prioritize the integration of libraries and digital science in transport and logistics education in Nigeria and Namibia to support workforce development, economic growth, and sustainable development in these countries.
