Amprolium is a derivitive of B group vitamins and works by inhibiting the coccidia's ability to feed. For this reason the medication MUST be administered continuously for the specified period of time. Usual treatment programs consist of 30 grams in 25 litres (or 5g in 4 litres) of water for 7 days. To allow the correct development of immunity, some exposure to coccidia is required. It is recommended that the medication level be reduced to 15 grams in 25 litres of water for a further 7 days.
Amprolium has no witholding period and can be used right up to slaughter of chooks and poultry. Use permitted in egg production. No withholding period. Can be used at a low level continously in the feed, or as an occasional preventative for 1 day at full strength, before any symptoms are present.
