I have read all of the posts I could find concerning cocci prevention and treatment. But I am not sure I have everything clear. Albon/Sulmet are sulfas. Are they only for treatment? Corid/Amprolium, Is this for treatment or prevention or both? Doeling (born 4/11/08) was wormed on July 14th with your recommended dosage of Ivomec+. Next day I started her on treatment for cocci. Sulmet at the recommended dosage on here. 5 day treatment. Refecaled on the 21st, clear. So, now here we are a month later and she is again unthrifty and fecal shows roundworms and cocci at high levels. None of the other goats have the levels of cocci that she does and appear to be tolerating the low worm loads they are carrying. Ie, good eye color and good condition. Up till now, I have not implemented a worming regimen. My property had no animals of any kind on for at least 10 years before we purchased it. We have been here for 3 1/2 years and my goats have only been wormed about every 6 months. I have fecaled before worming and then again after to be sure that my wormer is working. This has worked until I purchased two 8 week old doelings this spring. However, until I found this site, I had never heard of the 3x 10 days apart worming. I know she needs to be treated, but would like advice on what protocol to use. I live in the Pacific Northwest it is generally cool and damp. Thus far, Ivomec still works for us. Doeling is Alpine and 4 months old. She is still on a bottle, but only gets about 24 oz. a day, straight goat milk. Gets alfalfa hay free choice, meat goat pellets w/rumensin (1 lb. daily), alfalfa pellets (1 lb. daily) free access to a decent mineral (from what I have read on here, could be better, but I am working on it), fresh water 3 x day and free access to 1 acre of pasture (kind of crappy right not, but there). I know how much she is eating because each goat gets fed separately and feed is weighed. Then I know if someone is not eating. I worm first, if I am reading the posts correctly. Then start the cocci treatment, right? Now, if I am worming with Ivomec +, do I do the 3x 10 days apart? And do I treat her with Sulmet or Corid? Last time she was treated with Sulmet. I have both here. Should I have re-treated with the Sulmet? If I treat with Corid, do I then re-treat in 20 days? If she continues to have problems, what other issues should I examine? None of my other goats are having problems. Even the Miniature Alpine I purchased at the same time from the same breeder who is a week older. Sorry this is so long, just wanted to put in as much information as possible.
