Fenbendazole For Pigs

Parasite control, in addition to control of viruses and bacteria, must be part of a comprehensive herd-health program in every swine production system. Gastrointestinal worm infections may result in significant economic losses. Signs of infection are general and not readily apparent, since worm infections rarely cause elevated mortality levels. Some worms commonly found in pigs are roundworms (Ascaris suum), nodular worms (Oesophagostomum species), intestinal threadworms (Strongyloides ransomi), whipworms (Trichuris suis), kidney worms (Stephanurus dentatus), and lungworms (Metastrongylus species). Anthelmintics or “dewormers” are chemical substances that can be added to pig diets to control parasitic worms.

Fenbendazole is a broad-spectrum anthelmintic belonging to the benzimidazoles, effective against roundworms and, depending on the dose, also against some tapeworms (e.g. Moniezia spp) as well. It is ineffective against flukes (e.g. Fasciola hepatica adults) at the usual therapeutic dose. It is completely ineffective against external parasites. Oral administration is the rule. It is used massively in all kinds of livestock (mainly in drenches and feed additives), and abundantly in pets (often in tablets, pills, etc. or oral suspensions) and horses (mostly in oral pastes & gels). There are hundreds of generic brands worldwide, also in mixtures with other anthelmintics. Fenbendazole is not used against agricultural or household pests.

Description

Fenbendazole. Fenbendazole has a relatively broad spectrum of activity. It is effective against mature and immature forms of common worms that infect pigs. However, fenbendazole has a higher activity when given at low doses for several days (9 mg per kg body weight with the dose divided over 3 to 12 days) than when single-dosed. No withdrawal time is required when this product is used at the recommended dose. Swine Dewormer Premix is a medicated premix that provides fenbendazole for mixing complete dewormer feeds. The 3 to 12 day treatment removes and controls six major internal parasites in swine of all growth stages, including weanling pigs, pregnant sows and boars.

Features of Fenbendazole For Pigs

Benzimidazoles – Flubendazole (e.g. Flubenol: Janssen Animal Health) and Fenbendazole (e.g. Panacur: Intervet Schering Plough Animal Health) are available as oral preparation only, either for incorporation in feed, top dressing of feed or medication via the water. Specific preparations are available which are licensed to be applied directly to individual pigs by way of top dressing; products licensed for incorporation into feed only cannot be used for top dressing.
These chemicals are solely anthelminthics (wormers) but have the advantage of being effective against eggs, larvae and adult worms.

Caution

Consult veterinarian for assistance in the diagnosis, treatment and control of parasitism. Parasite control comes through strategically timed dewormings where infections are terminated at key times in the life cycle of an infection and in management schemes of an operation. SAFE-GUARD® is a registered trademark of Intervet, Inc., Millsboro, Delaware, for Fenbendazole.
