Abstract
Echinacea dietary supplements are useful adjuvants for live anticoccidial vaccines. Feed supplementation with Echinacea preparations enhances the immune response to such vaccines. Echinacea purpurea in amounts of about 0.1% to 0.5% administered for about two weeks to day-old chicks has been found effective for providing significant weight gain compared to vaccination alone.
