Research on worming chickens with albendazole

Quote:
Hope Pine Grove don't mind if I answer this. You give it orally, undiluted. 1/4 cc for standard size birds, 1/8 of a cc for bantams.
ETA: The label should say: Albendazole 11.36% (equivalent to 113.6 mg/ml)

Great post. I just have one question, did you administer any follow up doses or did just one dose do the trick?

 

[FireTigeris]

Ack I was hoping there was an answer for this...

I need the withdraw time and the dosing time.

HI, did you get an answer on whether to repeat the dose on the Albendazole for deworming your chickens? I just used it last Friday and also would like to know the answer to that. Thanks so much!

One of my hens was looking thin and then I saw a roundworm in droppings this week-ugh! /img/smilies/sickbyc.gif Based on various posts on this site, I decided to worm my hens with Valbazen (albendazole).  Afterwards, I had some serious second thoughts, which led me to do some additional investigation, which ultimately calmed my nerves.  The recommendation to use Valbazen was a good one!  Thanks to BYC! /img/smilies/love.gif


The article that calmed my nerves describes research done on broilers using 3 dose levels of albendazole (5 mg, 10 mg and 20 mg/kg body weight) and then measuring the effectiveness by doing necropsy analysis 7 days after treatment.  Here is the link to the journal article: http://japr.fass.org/cgi/content/full/16/3/392#T1


Summary of study findings and how Ill manage my flock:

1.  There was a high incidence of worms in this 1 year old flock, maintained on litter.  Incidence:

o  Ascaridia galli (roundworms)73% adults; 80% larvae,

o  Heterakis gallinarum (cecal worms)100% adults; 73% larvae

o  Capillaria obsignata. (capillary or thread worms)100% adults; 100% larvae

o  Raillietina cesticillus (tapeworms)53%


2.  There were no adverse effects of albendazole treatments on bird appearance, behavior, apparent appetite, and weight gain.


3.  Good control was seen at 10 mg/kg for all worms except tapeworms, which required 20 mg/kg for control.


4.  Through other medical websites, I found that albendazole is used to treat humans with worm infections.


5.  Conclusions:

o  Since there is a very high incidence of worms in chickens raised on litter, I plan to worm my chickens 2 times per year, or more frequently if I observe worms or weight loss.


o  I will use 10-20 mg albendazole/kg body weight, which translates to:

-  2 pound chicken ~0.1 ml Valbazen

-  4 pound chicken ~0.25 ml Valbazen

-  7 pound chicken ~0.5 ml Valbazen


o  Ill not eat the eggs for 2 weeks, although since albendazole is used in humans, this is probably not essential.


I hope others find this useful.

Thank you for this info! I have a pale faced/lethargic RIR. Going to give the albendazole see if worms aren't be problem.
I have a Peking duck whom I'd also like to treat. Does anyone know if this is safe for him?

What is the youngest you would deworm? I have some 2 month old chicks but found tapeworms in one of the adult hen's poos, so I want to just do them all but not sure if I should wait...

Also, did just one dose work for you?

Can you post a pic?

Of the poo or of the young chickens?

Oh boy, this is an old thread, so I hope somebody can give me an answer. I'd like to dose my chickens in their water. What would be the proper amount?

 

[mickeymousears]

I'm thinking you don't want to dose the water because there's no way to control the amount of meds each bird gets.
