Amproline for poultry has the strongest effect on the tender and pile-shaped Eimeria in chickens, but its effect on the toxic, Brucella, giant and mild Eimeria is slightly inferior. Usually, the therapeutic concentration cannot completely inhibit the production of oocysts. Therefore, both at home and abroad, it is often used in combination with ethoxyphenymethyl ester, sulfamethoquinoline, etc., to enhance the therapeutic effect.
