Problems solved by technology

However, due to the influence of factors such as vaccine production quality, vaccine transportation, storage conditions and methods, selection of immunization procedures, occurrence of immunosuppressive diseases, and the effect of maternal antigens, the application of Newcastle disease vaccines is limited, especially when Newcastle disease occurs. The effect is not satisfactory, making Newcastle disease still one of the biggest epidemics that endanger the chicken industry
So far, no drug has been proven to have a definite preventive effect on this disease

Description

technical field [0001] The invention relates to the field of feed technology, in particular to an immune additive for preventing chicken Newcastle disease. Background technique [0002] Newcastle disease (Newcastle disease, ND), also known as Asian chicken plague, pseudo chicken plague, is an acute, highly contagious infectious disease. It has been prevalent in our country for many years. It is an old disease, but it is still one of the most serious infectious diseases that endanger poultry in our country. It is characterized by fever, dyspnea, severe diarrhea, mucous membrane, serosal hemorrhage and necrosis, with a slightly longer course of disease accompanied by neurological symptoms. [0003] At present, the prevention and control of chicken Newcastle disease adopts Newcastle disease vaccination and has received good results. However, due to the impact of factors such as vaccine production quality, vaccine transportation, storage conditions and methods, selection of im...
