Live Vaccine PULVAK IB Primer

Infectious bronchitis of chickens (IB) is characterized by high viral variability, which makes standard monovalent vaccines insufficiently effective against new variant strains. For comprehensive flock protection against a wide range of threats, Zoetis offers the live dry vaccine PULVAK IB Primer. This vaccine contains high concentrations of two key attenuated strains — the classical “H-120” (Massachusetts serotype) and the variant “D274”, providing strong cross-protection for the respiratory and reproductive systems of poultry.

The main advantage of PULVAK IB Primer for modern poultry farms is its exceptional safety and versatility. Its low reactogenicity ensures gentle action on the flock without post-vaccination complications. The vaccine can be combined with other immunobiological products, allowing veterinarians to optimize vaccination schedules, save staff time, and reduce stress for birds. A robust immune response develops within 10–14 days after administration and reliably lasts for at least 3 months.

Implementing PULVAK IB Primer in your farm’s veterinary protection program is a proven step to increase biosecurity, as the vaccine has been successfully used in industrial poultry farming for over 5 years. By blocking both classical and variant bronchitis, it ensures high feed conversion in broilers and maintains maximum egg production in layers. This is a strategic solution to protect your agribusiness profits.
