RESISTANCE PREVENTION

There are no reports on resistance of poultry roundworms to benzimidazoles more than 40 years after their introduction for this use.

This means that if this product does not achieve the expected efficacy against the mentioned parasites, it is most likely that it is not due to resistance but to incorrect use, which is the most frequent cause of product failure.

However, to prevent or at least delay resistance development it is a good practice to periodically alternate anthelmintics (rotation) with different modes of action.

Alternative chemical classes/active ingredients to prevent resistance of gastrointestinal roundworms through product rotation in poultry:

These alternative products may not be available in all countries or may not be effective against all the concerned parasites.

It is highly recommended to periodically check the resistance status of each property performing appropriate tests (e.g. fecal egg counts) under supervision of a veterinary doctor.

COMMENTS

FLUBENVET 1% Medicated Premixture is a classic anthelmintic for poultry from ELANCO containing generic flubendazole.

Flubendazole is a veteran anthelmintic introduced in the 1970s (by JANSSEN). It has a broad-spectrum of activity against roundworms (gastrointestinal and pulmonary) but is ineffective against tapeworms and flukesFlubendazole also kills eggs of roundworms (ovicidal activity). As all benzimidazoles, flubendazole has no efficacy whatsoever against external parasites (ticksflies, lice, mites, etc). Among the benzimidazoles flubendazole is quite comparable with mebendazole in terms of efficacy and safety. Flubendazole is moderately used in pig & poultry but rather scarcely in ruminants, horses or pets. It is not used in agriculture.

As all benzimidazoles (as well as other anthelmintics such as levamisole and tetrahydropyrimidines), flubendazole has no residual effect, i.e. it kills the parasites shortly after administration, but as soon as medicated feeding is interrupted it does not significantly protect the animals against re-infestation by infective stages in their environment.
