Marek's disease in the infectious agent reservoir of poultry industry - household farms

The distinctive feature of the virus of Marek's disease is its ability to remain in the host and ecosystem while evolving for a long time, due to which new problems in control and diagnosis of the disease are constantly created. In a period of market economy, private entrepreneurs are often neglected in the implementation of anti-epizootic measures against infectious, viral and invasive diseases, which leads to huge loss of chicken and enormous damage and losses. Owing to enormous economic damage caused by Marek's disease, the widespread circulation of its viruses and the danger of importation of its virulent strains for industrial poultry entails to significant economic losses, as time proves the need for mandatory preventive immunization of chickens, guinea fowls, pheasants, quail and turkeys, against disease Marek in homesteads. The purpose is to achieve intense and maximally long group immunity, preventing to importation of virus's virulent strains, propagation and the spread of infection for industrial poultry. The article gives the results of researches on studying the efficiency of vaccine-preventable against Marek's disease. In non-vaccinated livestock from control production shop was manifested Marek's disease with all clinical and pathological changes, whereas in the experimental production shop where vaccination was performed subcutaneously in the neck area, Marek's disease was absent. In comparison with the control group, livestock's safety of experimental production shop has increased to 17-18 % with absence of clinical implications of different pathologies of Marek's disease and also arising the productivity and resistance of the poultry' organism. The vaccination recommended be made to the chicken subcutaneously in the neck area based on the results obtained for the specific prevention of Marek's disease in the chickens of cross-country such as brown Highsex Brown, Rodonit-3 and Brown Nick, including the White-chested guinea-fowl, the hunting Romanian breed of pheasants, the quail of Pharaoh and turkeys BIG-6 households as a natural reservoir of infection for an industrial poultry.
