AbFen™ is an equine dewormer from Abler, which contains fenbendazole as its active ingredient. Fenbendazole for horses effectively removes and controls infestation of parasites, such as the encysted stages of cyathostomes or small strongyles. AbFen™ works by inhibiting the energy metabolism of equine parasites. Fenbendazole is known to have a wide therapeutic range. For this reason, fenbendazole is effective at targeting immature parasites and eliminating worm eggs. It is also the drug of choice for the management of roundworm infestations. Each sachet of AbFen™ contains 2250mg of fenbendazole granules. So, how many sachets of the product do you actually need for your horse?
Horses commonly suffer from colic. Colicky symptoms generally point to abdominal pain. Colic can develop if the horse’s digestive function is affected. How horse owners manage their horses also plays an important role in the development of equine colic. Colic is not a result of digestive dysfunction. In fact, pregnancy and even infections can cause colic in horses. In the year 1986, Morris Animal foundation reported that colic is attributed to many horse deaths in that year.
A British survey has shown that half of all ponies and horses are not receiving correct deworming for encysted small strongyles, the most common equine parasites found in equines. This can be an alarming news for experts. The encysted small strongyles or redworms – one of the stages involved in the life cycle of the parasite – are responsible for up to 90% of the small strongyles burden in horses and can be a serious health problem.
Spring is the time when horses are taken out to graze on to fresh pasture after being confined during winter and it is an important season to contemplate strategies for deworming. Giving the right dose of equine dewormers in early spring brings a positive effect to parasite control for the summer, and can also reduce the need for an extra worming dose during this season.
While it is unlikely for horses to suffer harmful side effects from deworming too frequently, the health of the horse can be compromised in the long run when parasites start to develop resistance against horse wormers.
In the 1960’s, horse worming strategies were developed and followed simple protocol – to treat the horse for 8 weeks using the available wormer benzimidazole (an anthelmintic drug used to kill end expel intestinal worms). There was a significant improvement on mortality from parasitic infections. In the following decades, new wormers have been developed and veterinarians recommended rotating different classes of equine dewormers, but using the same strategy for every horse.
However, equine parasites responded to dewormers in a different way – they have developed resistance. For instance small strongyles, the most prevalent equine parasite in adult horses at present, developed resistance to two major classes of dewormers, the benzimidazoles and pyrantels. Small strongyle resistance resulted from the rotation of drugs, some of which still exhibit efficacy against this particular parasite, and some of which do not.
Experts believe that it is time to abandon the old practices of deworming a horse. Horses shed worm eggs via their feces; therefore, it simply doesn’t make sense to deworm a horse with the same 8-week treatment course. Once you have determined the frequency at which you need to treat your horse, it is important to make sure that you choose products that actually exhibit an efficacy against parasites found on your farm. This practice is also called strategic deworming and is considered a better way to control parasites and help avoid the risk of drug resistance in your area.
Strategic deworming works best when you get your veterinarian involved. The first step to be done by your veterinarian is to conduct a fecal egg count on each horse, this will determine the type of parasite your horse has and which among your horses are high or low shedders. With the results, your vet will recommend to you the frequency of worming. Most likely, the vet will perform follow-up fecal egg count reduction tests to check whether your chosen wormers still work against the culprits on your farm. In the end, you might find that it is just appropriate for you to stop using some of the dewormers that were once part of your rotation program.
Strategic deworming can help you save money in the long term as broad spectrum agents may be not be required as often as they used to for some horses.
For broad spectrum agents found at affordable prices, choose Abler. Abler has all your deworming needs to include in your equine worming program.
