Active Drug Ingredient:
Each 100 ml contains 34 grams piperazine base (present as sulfate).
Inert Ingredients:
Water, color, flavoring, preservatives and stabilizer.
Directions
For best results, remove water in the evening (except during hot weather). Then, early the next morning, give Wazine-34 in the drinking water. 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 1 day or less. Worming every 30 days helps break the large roundworm life cycle.
Turkeys
Under 12 weeks of age: for each 1000 birds, use 10 fluid oz. (300 ml) of Wazine-34 in 20 U.S. gallons (76 liters) of drinking water.
Over 12 weeks of age: for each 1000 birds, use 20 fluid oz. (600 ml) of Wazine-34 in 40 U.S. gallons (150 liters) of drinking water.
Worm turkeys at 4-6 weeks of age and thereafter at 30 days or as needed.
Chickens
4 to 6 weeks of age: for each 1000 birds, use 5 fluid oz. (150 ml) of Wazine-34 in 10 U.S. gallons (38 liters) of drinking water.
Over 6 weeks of age: for each 1000 birds, use 10 fluid oz. (300 ml) of Wazine-34 in 20 U.S. gallons (76 liters) of drinking water.
the difference in Wazine 34 and 17 is that each 100ml has 34 grams of piperazine while the 17 has 17 grams of piperazine per 100ml.
