Summary of study findings and how a flock was managed:
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
Still we only worm with chemical wormers when a fecal test shows positive and we test twice a year. We use a preventative the rest of the time called Verm-X. We are in AZ where it is very dry and can't remember the last time we had worms in either flock....
Southerndesert, this is a very good article, I bookmarked the website. The article mentions that the 3 or 4 most common worms found in chickens are roundworms, capillaria and cecal worms, also tapeworms. I guess the part that confuses me is that this article has shown tests with albendazole killing those 4 common worms. But the manufacturers label on albendazole does not mention them, just other worms, (except for tapeworms). I wish they'd all get their facts straight.
The best thing I've learned here is that I've been treating with Wazine for 4 years, and not realizing that there are other worms I need to kill. I wonder if my chickens have suffered from that. I don't know. But now I will be using more affective wormers, like Valbazen, fenbendazole, and Pyrantel Paomate, and kill all the little suckers. I live in Florida and for sure the worms proliferate here.
I also have to say that it shocked me when a 10 week old chick I had pooped round worms right in front of me. I didn't think they were old enough.
Our soil is the same seminolewind. That's why I worm every 3 months. You have to keep in mind that valbazen, safeguard and ivomec products and other wormers are all "off label" products and the manufacturers will readily state that their products are not for use in chickens. This is why you never see info regarding dosages nor withdrawal times on the manufacturer labels. Wazine is approved for use in chickens. Not only wormers but other products such as corid, tylan and many other antibiotics, anti-protozoal meds etc...are not labeled for use in chickens. Also, if you look at the above study "Summary" and notice the percentage of kills...some more than others...that is another reason why it's important to follow up with a second dosing 10 days later with albendazole...to kill the leftover worms that the first dosing didnt get.
Valbazen (albendazole)is a cattle/sheep wormer as stated on the label.
Safeguard (fenbendazole/panacur) is an equine paste and there's safeguard liquid goat wormer.
Most ivomec products are for cattle and horses in pastes, injectables, oral drench and pour on.
For rotation purposes, I use valbazen, safeguard liquid goat wormer, and infrequently use zimectrin gold horse paste.
