MEVAC™ LASOTA + H120

Combating Respiratory Disease in poultry operations

Respiratory diseases are among the most devastating diseases in the poultry industry; in most cases, these are the result of more than one pathogen involved. Among several avian viruses with tropism of the respiratory tract, infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) are the most important viruses compromising poultry health worldwide.¹

Using various strategies such as combination of live attenuated and inactivated vaccines or the development of combined ND+IB vaccines, will lead to effective programs that contribute to poultry health and food security in many countries on a global scale.²

Administration

The vaccine should be administered via the eye drop, spray, or drinking water routes.

• Eye drop: Reconstitute 1,000 doses into 3 to 5 ml of non-chlorinated drinking water and subsequently dilute it into 30-50 ml of non-chlorinated drinking water. Use a calibrated dropper to distribute 30-50 μl-drops. Place one drop of the vaccine solution on the eye of each bird, allow the drop to spread, and release the bird.
• Spray vaccination: Spray the vaccine solution above the birds using a sprayer device capable of producing micro-droplets (mean diameter 80-100 μm). Make sure that birds are closely confined together during spraying. The ventilation system of the poultry house should be inoperative during the spray administration.
• Drinking water: When using tap water, treat all water with skimmed milk powder at a rate of 2.5 g per liter to neutralize traces of chlorine. Distribute the vaccine solution at the time of use to birds. Birds should be deprived of water for two hours before vaccination.
