Broilerbron-H N-79 (HC-405/M2.5) Indications For Use

For vaccination of healthy chickens 2 weeks of age or older via drinking water administration to aid in the prevention of Newcastle Disease and infectious bronchitis (Mass Type).

Vaccination Programs

Many factors must be considered in determining the proper vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive chickens held in a proper environment under good management. In addition, the response may be modified by the age of the chickens and their immune status. Seldom does one vaccination under field conditions produce complete protection for all individuals, in a given flock. The amount of protection required will vary with the type of operation and the degree of exposure that a flock is likely to encounter. For these reasons a program of periodic revaccination may be required.


Only Vaccinate Healthy Birds

Consult your poultry pathologist for further recommendations based on conditions existing in your area at any given time.

This vaccine offers protection with mild reaction.


Newcastle Disease virus can cause inflammation of the eyelids of humans lasting two or three days. The user should avoid contaminating his hands, eyes and clothing with this vaccine.
