Efficacy of fenbendazole against helminth parasites of poultry in Uganda.

Ssenyonga GS.
Abstract

Fenbendazole 4% (Panacur, Hoechst) administered in feed was used to treat chickens infected with Ascaridia galli, Heterakis gallinarum and Railletina spp. It was also used to treat Syngamus trachea in broiler birds. There was a marked drop in helminth egg counts in the faeces on the second day of treatment and the faeces became negative by the seventh day after the last treatment. Post-mortem examination 15 to 21 days later showed that the drug was 100% effective against Ascaridia galli and Heterakis gallinarum at 10 mg/kg. However, for complete removal of Railletina spp. 15 mg/kg was required. Similarly 20 mg/kg fenbendazole was effective against Syngamus trachea. It was concluded that fenbendazole is suitable for the treatment of the important intestinal and tracheal worms of poultry, a dose of 15 to 20 mg/kg for 3 consecutive days being recommended for use under field conditions.

I'm going to call the vet for further clarification in the morning but I was just curious tonight if she was overdosed. It certainly would explain so much. Does it sound like it to you?

If you go back a few pages you can see the history of what I wrote with symptoms and dosage etc.

Let us know what the vet says.

I use the large 5 day dose all of the time, but I guess there have been a few people that have reported experiences similar to what you described.
