I don't mean to beat the subject into the ground. But although I trust the site I got this from (listed at the end) I didn't see when it was posted so don't know how old it is. * 1 ounce = 29.5ml. I'm using chickens because I could look up how much a chicken eats a day, and am using 1/2 cup or 4oz.( according to nutrena a laying hen eats 1.5lb/week) at that rate 15lbs of treated food would feed 60 chickens, giving each chicken only .491ml of safeguard.
1 oz Safeguard or Panacur per 15-20 lb feed
Dissolve the fenbendazole product in one cup of water. Mix this solution well into the feed and give to the birds as their only feed source for one day. When completely consumed, untreated feed can be given. Be sure that the commercial medication contains 10% fenbendazole.
Safeguard is a product of Ralston Purina, and Panacur is a product marketed by American Hoechst. One ounce of medication will treat about 1000 10-oz bobwhite quail. Adjustments of the amounts of medication and feed needed may be necessary depending on the number and size of the birds.
1.2 oz Safeguard or Panacur in 100 lb feed
4 oz pkt of "Worm-A-Rest Litter Pack" (Ralston Purina) in 50 lb feed
5 lb bag of "Worm-A-Rest Mix Pack" in 495 lb feed
Feed all the medicated feeds free-choice for three consecutive days. The feed mixtures provide 75 ppm fenbendazole. Quail will receive about 1.7 mg/bird each day for adult birds or 2.75 mg/lb of bodyweight.
Fenbendazole has been shown to be a very effective treatment for eliminating Capillaria (capillary worms), Heterakis (cecal worms), Ascaridia (roundworms), and Syngamus spp. (gapeworms). Toxicity from overdosing with fenbendazole is very remote. Research indicates that amounts up to 100 times the recommended dosages have been given under research conditions without adverse effects to the birds. Use of this product during molt, however, may cause deformity of the emerging feathers.
