Профілактика хвороб печінки у курей яєчного напрямку продуктивності
The article gives brief statistics of state poultry industry in Ukraine, its importance in the market of the country and problematics. The most common pathologies of non-contagious etiology in poultry associated with impaired metabolism are examined in the article. The data on age features of metabolism, level of metabolic processes and critical physiological and technological periods in laying hen sis shown. The greatest load takes over the liver, which is directly or indirectly involved in all metabolic and functional changes of hepatocytes cause a breach in the systems of organs and in organism as a whole. The analysis of scientific literature and numerous studies in recent years shows that the disease of the liver (hepatosis or dystrophy of hepatocytes, hepatitis and cirrhosis) are very common among poultry and are composed from 5.0 to 50.8% of all non-communicable diseases. A feature of these diseases is hidden (subclinical) course, which complicates their timely diagnosis and effective prevention. One direction solution to the problem is to normalize metabolic processes in the body and morpho-functional state of the liver is to use hepatoprotectors. It is established that the group of these medications in recent years, acquired widespread adoption due to the intensive rearing of poultry and for protection their organism against unfavorable external and internal environment. Hepatoprotectors, improving metabolism in the liver, provide intensive growth, development and high productivity of poultry. The selection studies of physiological period of laying hens for using hepatoprotectors in the prevention of liver diseases is required, in particular hepatosis for conducting clinical examination of how the system measures to prevent metabolic diseases of poultry. It is necessary to improve methods of early diagnosis the dysfunction of the liver and use effective methods of correction of metabolic processes.
