The vaccine provides active immunisation of future layer and breeder chickens from four weeks of age to reduce air-sac and foot-pad lesions and egg production losses caused by Mycoplasma synoviae infections. The infection causes significant economic loss, particularly in laying hens, where egg production in affected layers can be reduced by 5-10%.

Mycoplasma gallisepticum is a bacterial pathogen responsible for chronic respiratory disease in chickens and infectious sinusitis in turkeys. The live strain of the bacteria used for ECOVAXXIN^® MG is a naturally attenuated isolate shown to be safe for young chicks.
