Cygro® 1% Dosage and administration Use feed containing Cygro® 1% as the only feed for the period during which broilers and turkeys are at risk. Cygro® 1% should be mixed thoroughly into broiler feeds at a level of 500 grammes per tonne. This will provide 5 mg/kg maduramicin ammonium. To optimise blending, Cygro® 1% should be diluted at least 1 to 10 with supplement or feed ingredient prior to incorporation into the final mix.
