Wazine® 17 Fleming Labs wormer for use in drinking water for the removal of large roundworms from turkeys and chickens and large roundworms and nodular worms from swine. For better result, remove water in the evening (except during hot weather). Then, early the next morning, begin water medicated with Wazine-17. Provide medicated water only, distributed in waterers sufficient in number so that all birds or animals have access to water. The medicated water should be consumed in one day or less. Worming every 30 days is necessary to break the large roundworm life cycle.
