Chicken Coccidiosis Vaccine Description
This live quadrivalent coccidiosis vaccine is formulated with four important Eimeria species responsible for the majority of clinical and subclinical coccidiosis cases in poultry production.
Coccidiosis is a highly prevalent parasitic disease causing intestinal damage, poor feed conversion, reduced growth rates, and increased susceptibility to secondary infections. It remains one of the most economically significant diseases in the poultry industry worldwide.
Unlike anticoccidial drug programs, this vaccine enables birds to develop natural immunity through controlled exposure to attenuated oocysts. This approach reduces dependence on anticoccidial drugs and helps prevent drug resistance.
The vaccine is designed for early-life administration (3–5 days old), allowing birds to establish protective immunity before field exposure. Immunity develops within 14 days post-vaccination and lasts for approximately 150 days, covering the critical production period for broilers and early-stage layers.
