A recent trial* failed to demonstrate any benefit from supplementing diets with an egg-derived compound apparently demonstrating an anti-Interleukin-10 effect. Challenging caged broilers with Eimera tenella and E. acervulina reduced weight gain, feed intake and feed conversion compared to uninfected controls. Neither oocyst shedding, serochemistry nor hematological parameters were improved by administration of the egg-based anti-IL-10 additive.
