Efficacy of albendazole of Syngamus trachea tested in groups of 8 to 9 turkeys experimentally infected with 500 larvae each at the age of 8 days. From day 17after infection, the animals were orally dosed with albendazole at 10, 5 or 2 mg/kg b.w. over 3 to 5 successive days. The efficacy was evaluated by daily inspection ofsymptoms, daily faecal egg counts and worm counts at post mortem on day 24after infection. The efficacy in the treated groups amounted to 100%, 100% and 94%, respectively. Remnants of wormpairs - mainly disintegrating males - were found in several animals of medicated groups as against all alive wormpairs in the control turkeys. The study shows high efficacy of albendazole at reduced dose rate against patent gapeworm disease in turkey.

Devada K.; Sathianesan V., 1989: Comparative anthelmintic efficacy of mebendazole thiabendazole and albendazole against syngamus trachea infection in chicken. Kerala Journal Of Veterinary Science. 20(1): 59-64

Three anthelmintics viz., mebendazole, (Gulfic) thiabendazole (MSD) and albendazole (SKF) were tried against Syngamus trachea infection in chicken under experimental conditions. Mebendazole dosed at a rate of 40 mg per kg body weightwas found to be most effective with 96.22 per cent reduction of eggs in the droppings, 88.1 per cent of disappearance of worms in the trachea and 95.52 per cent of weight gain of the treated birds. This was closely followed by albendazole administered at 15 mg per kg body weight, which had an efficacy of 95.14 per cent 76.19 per cent and 95.02 per cent in the respective three parameters. Thiabendazole given at a dose rate of 500 mg per kg body weight showed anefficacy of 89.27, 45.24 per cent and 94.18 perc cent based on the egg counts, worm counts and gain in body weight of the medicated chicks respectively. Thiabendazole was found to be the least effective when compared to the otherdrugs tried.

Thanks for sharing that. Would you know how fast gapes will kill a bird?

Of course I'd like to know. Please tell me you didn't lose one.

Sorry, I mis-read that! I have no idea how fast they can kill.

No, I haven't lost any birds. I am still trying to figure out what the problem was with that yearling hen that I sent you the video of last fall that was yawning constantly. Anyway, it was still doing it a couple of weeks ago and with the severe cold it was looking a bit worse. She has good weight and lots of meat on her breast, I brought her in and gave her a heat lamp and started her on Corid and Safeguard for five days. We also brought her in a friendly little chicken to keep her company in the parrot cage.

She looks to be right as rain, no yawning or coughing at all. I might add that she had no other symptoms when I brought her in. Brad told me to cull her last fall, but I didn't do it. Last year I gave her the whole gambit of anti-biotics, Corid, and Safeguard and she got moderately better after about six weeks of being in the infirmary. Now the weather is getting nice she will be going back into gen pop.

From the first sign of seeing the bird "Gape" about 4 days is all you have. I lost a bronze hen two years go to gape,first noticed her on Sat eve and we had plans we couldn't get out for the next day so Monday called Craig Hopkins,he said to drench her with safeguard twice a day,,naturally my local farm store doesn't carry safegard for goats,,so the next morning I made to 35 mile trip to get a bottle and when I got home she had passed. i later learned that Ivermectrin will immediatedly shrink the size of the worm so the bird can start breathing better,sooner.

 

[KsKingBee]

That is good to know, thanks. What was the recommended dosage of Ivermec for gapes?

ETA, I guess she didn't have gapes if four days is all that she would have to live if she did have them.

 

[frenchblackcopper]

I think it was 5cc per dose,twice a day but that was 2 years ago and I havn't had it again. Next time I will use Ivermectrin instead since it shrinks the worm size while killing it.

I treated gapes with Safeguard once and the dose I used was 50mg/kg once a day for five days, but gapes were cleared in two or three days. If I ever have to treat them again I think I might try it twice a day, and might even try ivermectin with Safeguard.

This study suggests fenbendazole (Safeguard) for three days at 20mg/kg.

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.
