Location: Elwood, IN. | here is a list of deworming scheduals you can use and types of dewormers. i use the adult fast deworming program because we run a boarding facility. mickiebon Adult Fast Deworming Program: January ------------------------- Oxibendazole March ------------------------- Pyrantel Pamoate May ------------------------- Oxibendazole July ------------------------- Ivermectin September ------------------------- Pyrantel Pamoate November ------------------------- Ivermectin Adult Slow Schedule Deworming: On a slow schedule, the same dewormer is used every 2 months for 1 to 2 years. In theory, drug-resistant worms should emerge when the dewormer is not rotated. In practice, drug-resistant worms do not develop if ivermectin is used once or twice every 12 months in place of the selected dewormer. In facet, since resistance to ivermectin has never been demonstrated, ivermectin itself can be used as the selected drug in a slow schedule. Foal Deworming Program: 2 months old ------------------------- Ivermectin 4 months old ------------------------- Pyrantel Pamoate 6 months old ------------------------- Oxibendazole 8 months old ------------------------- Ivermectin 10 months old ------------------------- Pyrantel Pamoate 12 months old ------------------------- Oxibendazole Adult Seasonal Deworming Program: May ------------------------- Oxibendazole July ------------------------- Ivermectin December ------------------------- Ivermectin Adult Continuous/Daily Deworming Program: In this program the horse is fed Pyrantel Tartrate (2.64 mg/kg) in alfalfa pellets on a daily basis to control the adult intestinal forms of large and small strongyles, ascarids, and pinworms. Pyrantel Tartrate does not kill tissue stages of these worms, but (when used on a daily basis) does kill larvae before they begin their tissue migration. This has a great advantage for elderly and stressed horses, and in circumstances in which other methods have failed to reduce egg counts and numbers of infective larvae. One other asset of daily deworming is that, as opposed to other programs, Pyrantel Tartrate does not have to be given to all horses on the premises to control worms in a single individual. This is advantageous of boarding facilities and for farms where horses come and go frequently. A potential drawback is the risk that feeding low levels of a dewormer will lead to the development of drug-resistant worms. However, this does not appear to be a problem with Pyrantel Tartrate, a dewormer to which no parasite has yet developed resistance. Pyrantel Tartrate does not kill bots. Accordingly, a boticide should be administered in midsummer and late fall.
