Grand parent and parent poultry farms should be free from Pullorum and Fowl Typhoid diseases as well as public health important Salmonella. If you repetedly get positive reactors with whole blood agglutination test (S.Pullorum and Gallinarum) can we use SG9R vaccine for that farm.
Is this recommended? If we decided to use this vaccine how long we have to use the vaccine? Or without vaccine can we comntrol the disease
