[Dynamics of the immune titers in commercial layers raised under increased lighting intensity].
Investigations were carried out into the dynamics of the immune titers in commercial layers raised under equal conditions (exceptxor intense illumination for the control group). The trials were performed in the conditions of industrial poultry farming. Studied were the imune titers against NDV on the 14th, 21st, 35th, 68th, and 88th day following aerosol immunisation with the vaccinal strain Komarov. A higher titer for a more prolonged period in birds raised in the conditions of increased intensity of electric light within the range of 70--75 lx was established.
